Rasa offers the decentralized non-custodial liquidity market where users can participate as suppliers or borrowers. Suppliers provide liquidity to the market to earn a passive income, while borrowers can borrow in an over-collateralized (perpetually) or under-collateralized (one-block liquidity) fashion.
Rasa offers a comprehensive suite of features to facilitate decentralized finance (DeFi) operations.
Key Features
Decentralized and Trustless: Operates without a central authority, ensuring that all transactions are transparent and trustless.
Variety of Supported Assets: Supports a wide range of assets, allowing users to diversify their portfolios and manage risk effectively.
Dynamic Interest Rates: Utilizes advanced algorithms to provide competitive and dynamic interest rates for both lenders and borrowers.
Secure Collateral Management: Implements rigorous security protocols for collateral management, ensuring the safety of user funds.
Efficient Liquidation Mechanisms: Employs efficient liquidation processes to manage under-collateralized positions and protect the protocol's integrity.
Interoperability: Designed to integrate with DeFi platforms and services, enhancing its utility and user experience.
This tiered model incentivizes both lending and borrowing, ensuring sufficient liquidity and stable interest rates.
Collateral management is a crucial aspect of the Rasa Lending protocol, ensuring that loans are secure and the system remains stable. Key components of collateral management include:
Collateralization Ratio: The required ratio of collateral value to borrowed amount. This ratio ensures that loans are over-collateralized to protect against market volatility.
Health Factor: A measure of the safety of a borrower's loan, calculated as the ratio of the value of the collateral to the value of the borrowed assets. A higher health factor indicates a safer loan.
Collateral Types: Rasa Lending supports various types of collateral, each with its own collateralization ratio based on its risk profile.
Borrowers must maintain their collateral above the required ratio to avoid liquidation. The protocol continuously monitors the value of the collateral and the borrowed amount to ensure compliance.
The liquidation process in Rasa Lending ensures that the protocol remains solvent and that lenders' funds are protected. The key steps in the liquidation process are:
Triggering Liquidation: When a borrower's health factor falls below 1 (i.e., the value of their collateral is insufficient to cover their debt), the liquidation process is triggered.
Liquidation: Liquidators can liquidate the under-collateralized loans at a discount. The system incentivizes liquidators to repay the loan and sell the collateral, restoring the protocol's balance.
Repayment and Collateral Sale: The liquidator repays the borrower's loan and receives the collateral at a discount. This process ensures that the protocol remains solvent and that the liquidator is incentivized to participate.
Liquidations help maintain the stability and solvency of the Rasa Lending protocol, ensuring that lenders' funds are always protected.
Rasa Lending employs several risk parameters to ensure the stability and security of the protocol. These parameters are designed to manage risk and protect users from market volatility. Key risk parameters include:
Loan-to-Value (LTV) Ratio: The maximum amount a user can borrow relative to the value of their collateral. A lower LTV ratio indicates a more conservative borrowing limit, reducing the risk of liquidation.
Liquidation Threshold: The collateral value at which a loan becomes eligible for liquidation. This threshold is set to ensure that loans are adequately collateralized and to protect against sudden market downturns.
Liquidation Bonus: An additional incentive for liquidators, provided as a percentage of the collateral value. This bonus ensures that liquidators are adequately rewarded for their efforts in maintaining the protocol's stability.
Reserve Factor: A percentage of the interest paid by borrowers that is reserved for the protocol. This reserve acts as a safety buffer to cover potential losses and ensure the long-term sustainability of the protocol.

These Terms of Service (the "Agreement") explain the terms and conditions by which you may access and use the Products provided by Rasa DAO (referred to herein as "Rasahom", "we", "our", or "us"). The Products shall include, but shall not necessarily be limited to, (a) app.rasa.finance a website-hosted user interface (the "Interface" or "App"). You must read this Agreement carefully as it governs your use of the Products. By accessing or using any of the Products, you signify that you have read, understand, and agree to be bound by this Agreement in its entirety. If you do not agree, you are not authorized to access or use any of our Products and should not use our Products.
To access or use any of our Products, you must be able to form a legally binding contract with us. Accordingly, you represent that you are at least the age of majority in your jurisdiction (e.g., 18 years old in the United States) and have the full right, power, and authority to enter into and comply with the terms and conditions of this Agreement on behalf of yourself and any company or legal entity for which you may access or use the Interface. If you are entering into this Agreement on behalf of an entity, you represent to us that you have the legal authority to bind such entity.
You further represent that you are not (a) the subject of economic or trade sanctions administered or enforced by any governmental authority or otherwise designated on any list of prohibited or restricted parties (including but not limited to the list maintained by the Office of Foreign Assets Control of the U.S. Department of the Treasury) or (b) a citizen, resident, or organized in a jurisdiction or territory that is the subject of comprehensive country-wide, territory-wide, or regional economic sanctions by the United States. Finally, you represent that your access and use of any of our Products will fully comply with all applicable laws and regulations, and that you will not access or use any of our Products to conduct, promote, or otherwise facilitate any illegal activity.
NOTICE: This Agreement contains important information, including a binding arbitration provision and a class action waiver, both of which impact your rights as to how disputes are resolved. Our Products are only available to you — and you should only access any of our Products — if you agree completely with these terms.
The Interface provides a web or mobile-based means of access to a decentralized protocol on various public blockchains, including but not limited to Lisk, that allows users to trade and borrow certain compatible digital assets (the "Rasa" or the "Protocol").
The Interface is distinct from the Protocol and is one, but not the exclusive, means of accessing the Protocol. The Protocol itself has one version, designated as v1, which comprises open-source or source-available self-executing smart contracts that are deployed on various public blockchains, such as Lisk. Rasa does not directly control or operate any version of the Protocol on any blockchain network. All control and operation is performed by Rasa Decentralized Autonomous Organization (Rasa DAO, DAO). By using the Interface, you understand that you are not buying or selling digital assets from us. We do not operate any liquidity pools on the Protocol, control trade execution, or control the lending platform. When traders pay fees for trades, those fees accrue to liquidity providers for the Protocol. When users pay interest to the lending platform, those fees accrue to Rasa DAO revenue pool in DAO MultiSig Treasury (treasury). When liquidators are liquidating lending positions, this happens only in case they become undercollateralized, liquidators can't liquidate healthy positions, and the whole liquidation is governed and secured by an autonomous automatic liquidation mechanism. Liquidated collateral is a liquidator incentive, where a certain amount is taken as fees that accrue to the treasury. No borrowed asset will be taken from the borrower from the liquidation event. The whole liquidation process is described in the documentation. As a general matter, Rasa is not a liquidity provider into Protocol liquidity pools and liquidity providers are independent third parties. The Protocol was initially deployed on the Lisk blockchain (Lisk), and can be deployed on other blockchain networks including by parties other than Rasa. Deployments on other networks typically make use of cross-chain bridges, which allow assets native to one blockchain to be transferred to another blockchain. Please note that digital assets that have been "bridged" or "wrapped" to operate on other blockchain networks (including to blockchains compatible with the Ethereum Virtual Machine that are designed to ensure the Lisk blockchain can effectively process more transactions or other blockchains that are frequently referred to as "Layer 2" solutions) are distinct from the original Lisk mainnet asset.
To access the Interface, you must use a non-custodial wallet software, which allows you to interact with public blockchains. Your relationship with that non-custodial wallet provider is governed by the applicable terms of service (with respect to a third party wallet, the applicable terms of service of such third party). We do not have custody or control over the contents of your wallet and have no ability to retrieve or transfer its contents. By connecting your wallet to our Interface, you agree to be bound by this Agreement and all of the terms incorporated herein by reference.
We may from time to time in the future offer additional products, and such additional products shall be considered a Product as used herein, regardless of whether such product is specifically defined in this Agreement.
When you use any of our Products, you may also be using the products, services or content of one or more third parties. Your use of such third party products, services or content may be subject to separate policies, terms of use and fees of these third parties, and you agree to abide by and be responsible for such policies, terms of use and fees, as applicable.
We reserve the right, in our sole discretion, to modify this Agreement from time to time. If we make any material modifications, we will notify you by updating the date at the top of the Agreement and by maintaining a current version of the Agreement. All modifications will be effective when they are posted, and your continued accessing or use of any of the Products will serve as confirmation of your acceptance of those modifications.

Any Other Unlawful Conduct. Activity that violates any applicable law, rule, or regulation of the United States or another relevant jurisdiction, including, but not limited to, the restrictions and regulatory requirements imposed by U.S. law.
Each of the Products is a purely non-custodial application, meaning we do not ever have custody, possession, or control of your digital assets at any time. It further means you are solely responsible for the custody of the cryptographic private keys to the digital asset wallets you hold and you should never share your wallet credentials or seed phrase with anyone. We accept no responsibility for, or liability to you, in connection with your use of a wallet and make no representations or warranties regarding how any of our Products will operate with any specific wallet. Likewise, you are solely responsible for any associated wallet and we are not liable for any acts or omissions by you in connection with or as a result of your wallet being compromised.
This Agreement is not intended to, and does not, create or impose any fiduciary duties on us. To the fullest extent permitted by law, you acknowledge and agree that we owe no fiduciary duties or liabilities to you or any other party, and that to the extent any such duties or liabilities may exist at law or in equity, those duties and liabilities are hereby irrevocably disclaimed, waived, and eliminated. You further agree that the only duties and obligations that we owe you are those set out expressly in this Agreement.
You bear full responsibility for verifying the identity, legitimacy, and authenticity of assets that you purchase from third-party sellers and we make no claims about the identity, legitimacy, functionality, or authenticity of users or assets (and any content associated with such assets) visible on any of our Products.
One or more of our Products may not be available or appropriate for use in your jurisdiction. By accessing or using any of our Products, you agree that you are solely and entirely responsible for compliance with all laws and regulations that may apply to you.
Specifically, your use of our Products or the Protocol may result in various tax consequences, such as income or capital gains tax, value-added tax, goods and services tax, or sales tax in certain jurisdictions.
It is your responsibility to determine whether taxes apply to any transactions you initiate or receive and, if so, to report and/or remit the correct tax to the appropriate tax authority.
Assets may be subject to terms imposed by their creators with respect to the use of the Asset content and benefits associated with a given Asset. For example, when you click to get more details about any of the Assets visible on the Interface, you may notice a third party link to the creator's website. Such websites may include additional terms governing the use of the Asset that owners of the Asset will be required to comply with. We are not a party to any such intrinsic Asset terms, which are between creators, sellers, and buyers. The buyer and seller are entirely responsible for communicating, promulgating, agreeing to, and enforcing those terms, and you are solely responsible for reviewing such terms.
Blockchain transactions require the payment of transaction fees to the appropriate network ("Gas Fees"). Except as otherwise expressly set forth in the terms of another offer by Rasa, you will be solely responsible to pay the Gas Fees for any transaction that you initiate via any of our Products.
You expressly agree that you assume all risks in connection with your access and use of any of our Products. You further expressly waive and release us from any and all liability, claims, causes of action, or damages arising from or in any way relating to your use of any of our Products. If you are a California resident, you waive the benefits and protections of California Civil Code § 1542, which provides: "[a] general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party."
BY ACCESSING AND USING ANY OF OUR PRODUCTS, YOU REPRESENT THAT YOU ARE FINANCIALLY AND TECHNICALLY SOPHISTICATED ENOUGH TO UNDERSTAND THE INHERENT RISKS ASSOCIATED WITH USING CRYPTOGRAPHIC AND BLOCKCHAIN-BASED SYSTEMS, AND THAT YOU HAVE A WORKING KNOWLEDGE OF THE USAGE AND INTRICACIES OF DIGITAL ASSETS SUCH AS LISK, SO-CALLED STABLECOINS, AND OTHER DIGITAL TOKENS SUCH AS THOSE FOLLOWING THE LISK TOKEN STANDARD (ERC-20) OR SIMILAR (SUCH AS ERC-20 TOKEN STANDARD OR ETHER (ETH)).

YOU UNDERSTAND THAT ANYONE CAN CREATE A TOKEN, INCLUDING FAKE VERSIONS OF EXISTING TOKENS AND TOKENS THAT FALSELY CLAIM TO REPRESENT PROJECTS, AND ACKNOWLEDGE AND ACCEPT THE RISK THAT YOU MAY MISTAKENLY TRADE THOSE OR OTHER TOKENS. SO-CALLED STABLECOINS MAY NOT BE AS STABLE AS THEY PURPORT TO BE, MAY NOT BE FULLY OR ADEQUATELY COLLATERALIZED, AND MAY BE SUBJECT TO PANICS AND RUNS.
FURTHER, YOU UNDERSTAND THAT SMART CONTRACT TRANSACTIONS AUTOMATICALLY EXECUTE AND SETTLE, AND THAT BLOCKCHAIN-BASED TRANSACTIONS ARE IRREVERSIBLE WHEN CONFIRMED. YOU ACKNOWLEDGE AND ACCEPT THAT THE COST AND SPEED OF TRANSACTING WITH CRYPTOGRAPHIC AND BLOCKCHAIN-BASED SYSTEMS SUCH AS ETHEREUM ARE VARIABLE AND MAY INCREASE DRAMATICALLY AT ANY TIME. YOU FURTHER ACKNOWLEDGE AND ACCEPT THE RISK OF SELECTING TO TRADE IN EXPERT MODES, WHICH CAN EXPOSE YOU TO POTENTIALLY SIGNIFICANT PRICE SLIPPAGE AND HIGHER COSTS.
IF YOU ACT AS A BORROWER THROUGH THE INTERFACE, YOU UNDERSTAND THAT YOUR COLLATERAL TOKENS MAY LOSE SOME OR ALL OF THEIR VALUE WHILE THEY ARE SUPPLIED TO THE PROTOCOL THROUGH THE INTERFACE DUE TO THE FLUCTUATION OF PRICES OF TOKENS IN A TRADING PAIRS OR LIQUIDITY POOLS OR IN ANY OTHER SOURCE OF PRICE THAT IS USED FOR THOSE TOKENS.
IF YOU ACT AS A LIQUIDITY PROVIDER TO THE PROTOCOL THROUGH THE INTERFACE, YOU UNDERSTAND THAT YOUR DIGITAL ASSETS MAY LOSE SOME OR ALL OF THEIR VALUE WHILE THEY ARE SUPPLIED TO THE PROTOCOL THROUGH THE INTERFACE DUE TO THE FLUCTUATION OF PRICES OF TOKENS IN A TRADING PAIR OR LIQUIDITY POOL.

WE MAY PROVIDE INFORMATION ABOUT TOKENS IN OUR PRODUCTS SOURCED FROM THIRD-PARTY DATA PARTNERS THROUGH FEATURES SUCH AS RARITY SCORES, TOKEN EXPLORER OR TOKEN LISTS. WE MAY ALSO PROVIDE WARNING LABELS FOR CERTAIN TOKENS. THE PROVISION OF INFORMATIONAL MATERIALS DOES NOT MAKE TRADES IN THOSE TOKENS SOLICITED; WE ARE NOT ATTEMPTING TO INDUCE YOU TO MAKE ANY PURCHASE AS A RESULT OF INFORMATION PROVIDED. ALL SUCH INFORMATION PROVIDED BY ANY OF OUR PRODUCTS IS FOR INFORMATIONAL PURPOSES ONLY AND SHOULD NOT BE CONSTRUED AS INVESTMENT ADVICE OR A RECOMMENDATION THAT A PARTICULAR TOKEN IS A SAFE OR SOUND INVESTMENT. YOU SHOULD NOT TAKE, OR REFRAIN FROM TAKING, ANY ACTION BASED ON ANY INFORMATION CONTAINED IN ANY OF OUR PRODUCTS. BY PROVIDING TOKEN INFORMATION FOR YOUR CONVENIENCE, WE DO NOT MAKE ANY INVESTMENT RECOMMENDATIONS TO YOU OR OPINE ON THE MERITS OF ANY TRANSACTION OR OPPORTUNITY.

EXCEPT AS EXPRESSLY PROVIDED FOR HEREIN, WE DO NOT PROVIDE REFUNDS FOR ANY PURCHASES THAT YOU MIGHT MAKE ON OR THROUGH ANY OF OUR PRODUCTS.
WE MAKE NO WARRANTIES OR REPRESENTATIONS, EXPRESS OR IMPLIED, ABOUT LINKED THIRD PARTY SERVICES, THE THIRD PARTIES THEY ARE OWNED AND OPERATED BY, THE INFORMATION CONTAINED ON THEM, ASSETS AVAILABLE THROUGH THEM, OR THE SUITABILITY, PRIVACY, OR SECURITY OF THEIR PRODUCTS OR SERVICES. YOU ACKNOWLEDGE SOLE RESPONSIBILITY FOR AND ASSUME ALL RISK ARISING FROM YOUR USE OF THIRD-PARTY SERVICES, THIRD-PARTY WEBSITES, APPLICATIONS, OR RESOURCES. WE SHALL NOT BE LIABLE UNDER ANY CIRCUMSTANCES FOR DAMAGES ARISING OUT OF OR IN ANY WAY RELATED TO SOFTWARE, PRODUCTS, SERVICES, AND/OR INFORMATION OFFERED OR PROVIDED BY THIRD-PARTIES AND ACCESSED THROUGH ANY OF OUR PRODUCTS.
SOME JURISDICTIONS DO NOT ALLOW THE LIMITATION OF LIABILITY FOR PERSONAL INJURY, OR OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THIS LIMITATION MAY NOT APPLY TO YOU. IN NO EVENT SHALL OUR TOTAL LIABILITY TO YOU FOR ALL DAMAGES (OTHER THAN AS MAY BE REQUIRED BY APPLICABLE LAW IN CASES INVOLVING PERSONAL INJURY) EXCEED THE AMOUNT OF ONE HUNDRED U.S. DOLLARS ($100.00 USD) OR ITS EQUIVALENT IN THE LOCAL CURRENCY OF THE APPLICABLE JURISDICTION.
THE FOREGOING DISCLAIMER WILL NOT APPLY TO THE EXTENT PROHIBITED BY LAW.
These terms constitute the entire agreement between you and us with respect to the subject matter hereof. This Agreement supersedes any and all prior or contemporaneous written and oral agreements, communications and other understandings (if any) relating to the subject matter of the terms.
You may not assign or transfer this Agreement, by operation of law or otherwise, without our prior written consent. Any attempt by you to assign or transfer this Agreement without our prior written consent shall be null and void. We may freely assign or transfer this Agreement. Subject to the foregoing, this Agreement will bind and inure to the benefit of the parties, their successors and permitted assigns.
In connection with your historic or current use of one or more of our Products, we may provide you certain incentives, prizes or rewards for completing certain activities, such as completing a certain number of transactions ("User Rewards"). Details regarding the criteria for earning a reward will be described within the applicable Product or official Rasaom documentation. Upon satisfaction of the criteria for obtaining a reward and subject to your compliance with the associated rewards terms, this Agreement, and applicable law — to be determined exclusively by Rasa — we will use commercially reasonable efforts to promptly transfer the earned reward to the digital wallet that you designate or have connected to the applicable Product. We reserve the right to change, modify, discontinue or cancel any rewards programs (including the frequency and criteria for earning such User Rewards), at any time and without notice to you.
We are not registered with the U.S. Securities and Exchange Commission as a national securities exchange or in any other capacity. You understand and acknowledge that we do not broker supply and borrow orders on your behalf. We also do not facilitate the execution or settlement of your orders, which occur entirely on public distributed blockchains like Lisk. As a result, we do not (and cannot) guarantee market best pricing or best execution through our Products or when using our Auto Routing feature, which routes trades across liquidity pools on the Protocol only. Any references in a Product to "best price" does not constitute a representation or warranty about pricing available through such Product, on the Protocol, or elsewhere.
We may provide any notice to you under this Agreement using commercially reasonable means, including using public communication channels. Notices we provide by using public communication channels will be effective upon posting.
If any provision of this Agreement shall be determined to be invalid or unenforceable under any rule, law, or regulation of any local, state, or federal government agency, such provision will be changed and interpreted to accomplish the objectives of the provision to the greatest extent possible under any applicable law and the validity or enforceability of any other provision of this Agreement shall not be affected.

Understanding Rasa Lending
Rasa Lending allows users to lend and borrow cryptocurrencies. By providing liquidity to the protocol, lenders earn interest on their deposits, while borrowers can access these funds by providing collateral. The platform operates without intermediaries, leveraging smart contracts to automate and secure transactions.
Lender: A user who deposits assets into the Rasa Lending platform to earn interest.
Borrower: A user who borrows assets from the Rasa Lending platform by providing collateral.
Collateral: Assets pledged by borrowers to secure their loans and minimize the risk of default.
Interest Rate: The percentage of interest paid by borrowers on their loans or earned by lenders on their deposits. Rates are determined dynamically based on supply and demand.
Liquidity Pool: A collection of assets provided by lenders, available for borrowers to draw from.
Liquidation: The process of selling a borrower's collateral when their loan falls below the required collateral ratio to protect the protocol from losses.
Lending: Users deposit their assets into the Rasa Lending protocol, adding liquidity to the platform. In return, they receive interest-bearing tokens representing their share of the liquidity pool.
Borrowing: Users can borrow assets from the liquidity pool by providing collateral. The amount they can borrow is determined by the collateral's value and the protocol's collateralization requirements.
Interest Rates: Interest rates for both lenders and borrowers are dynamically adjusted based on the utilization rate of the liquidity pool. Higher utilization leads to higher interest rates, incentivizing more deposits and balancing supply and demand.
Collateral Management: Borrowers must maintain a collateral ratio above a certain threshold to avoid liquidation. If the value of their collateral falls below this threshold, the protocol will automatically liquidate a portion of the collateral to repay the loan and maintain system stability.
Liquidation: When a borrower's collateral ratio drops below the required level, the protocol triggers a liquidation process. Liquidators can purchase the under-collateralized loans at a discount, incentivizing them to repay the loan and sell the collateral.
Rasa Lending's contract architecture is facilitating seamless interactions between various components of the protocol. The architecture consists of several core smart contracts that handle different aspects of the lending and borrowing process. This modular approach ensures that each contract has a well-defined role, enhancing maintainability and scalability.
These smart contracts are the AAVE V3 direct fork. They are battle-tested on various networks and are considered safe.
Key Contracts and Their Roles
LendingPool: The central contract that manages deposits, withdrawals, borrowing, and repayments. It interacts with other contracts to execute these operations and maintain the protocol's state.
LendingPoolCore: Stores the protocol's internal data, such as user balances, reserve configurations, and interest rate models. It serves as the data layer for the LendingPool contract.
LendingPoolConfigurator: Allows authorized entities to configure the protocol's parameters, such as interest rate models, collateral factors, and reserve assets. It ensures that the protocol can be updated and optimized as needed.
InterestRateStrategy: Determines the interest rates for borrowing and lending based on the utilization rates of the asset pools. Multiple strategies can be implemented to accommodate different assets and market conditions.
CollateralManager: Manages collateral for borrowers, ensuring that loans are properly collateralized and initiating the liquidation process when necessary.
PriceOracle: Provides real-time price data for assets, enabling accurate calculation of collateral values and ensuring that loans remain adequately collateralized.
Contract Interactions and Data Flow
The interaction between contracts in Rasa Lending follows a well-defined flow to ensure efficiency and security. Here’s how these interactions typically occur:
User Interaction: Users interact with the LendingPool contract to deposit assets, borrow funds, repay loans, and withdraw assets.
Data Access: The LendingPool contract interacts with the LendingPoolCore contract to access and update user balances, reserve configurations, and other protocol data.
Interest Calculation: When users deposit or borrow assets, the LendingPool contract calls the InterestRateStrategy contract to determine the applicable interest rates based on current utilization rates.
Collateral Management: When a user borrows assets, the LendingPool contract interacts with the CollateralManager contract to verify collateral requirements and manage collateral deposits.
Price Updates: The PriceOracle contract continuously updates asset prices, which are used by the LendingPool and CollateralManager contracts to assess collateral values and determine liquidation thresholds.
Liquidation: If a borrower's collateral falls below the required threshold, the CollateralManager contract initiates the liquidation process, interacting with the LendingPool contract to repay the loan and sell the collateral.

The RSToken is an interest-bearing token used within the Rasa Lending. It represents the user's stake in the underlying assets supplied to the protocol. This document provides details on the storage, functions, and events related to the RSToken contract.
name() external view returns (string memory): Returns the name of the token.
symbol() external view returns (string memory): Returns the symbol of the token.
decimals() external view returns (uint8): Returns the decimals of the token.
totalSupply() public view returns (uint256): Returns the total supply of the token.
balanceOf(address account) public view returns (uint256): Returns the balance of the specified account.
transfer(address recipient, uint256 amount) external returns (bool): Transfers tokens from the caller to the specified recipient.
allowance(address owner, address spender) external view returns (uint256): Returns the allowance of the spender for the owner's tokens.
approve(address spender, uint256 amount) external returns (bool): Approves the spender to use the specified amount of the caller's tokens.
transferFrom(address sender, address recipient, uint256 amount) external returns (bool): Transfers tokens from the sender to the recipient using the allowance mechanism.
getIncentivesController() external view returns (IRASAIncentivesController): Returns the address of the incentives controller.
setIncentivesController(IRASAIncentivesController controller) external: Sets a new incentives controller.
mint(address caller, address onBehalfOf, uint256 amount, uint256 index) external returns (bool): Mints tokens to the specified user.
burn(address from, address receiverOfUnderlying, uint256 amount, uint256 index) external: Burns tokens from the specified user and transfers the underlying asset to the specified receiver.
mintToTreasury(uint256 amount, uint256 index) external: Mints tokens to the treasury.
transferOnLiquidation(address from, address to, uint256 value) external: Transfers tokens during liquidation.
transferUnderlyingTo(address target, uint256 amount) external: Transfers the underlying asset to the specified target.
handleRepayment(address user, address onBehalfOf, uint256 amount) external: Handles repayment of the underlying asset.
permit(address owner, address spender, uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) external: Approves spending of tokens using a signed message.
BalanceTransfer(address indexed from, address indexed to, uint256 value, uint256 index): Emitted during the transfer of tokens.
Mint(address indexed caller, address indexed onBehalfOf, uint256 value, uint256 balanceIncrease, uint256 index): Emitted during the minting of tokens.
Burn(address indexed from, address indexed target, uint256 value, uint256 balanceIncrease, uint256 index): Emitted during the burning of tokens.
Transfer(address indexed from, address indexed to, uint256 value): Emitted during the transfer of tokens.
Approval(address indexed owner, address indexed spender, uint256 value): Emitted when approval for spending is granted.
To cover the most important flows: supply, borrow, repay and withdraw an asset, follow the steps below.
Go to
Connect your Web3 wallet (such as ) and make sure your network is set to the intended chain (i.e., ).
Choose the asset to Supply.
You can investigate the for this asset to make the decision. Clock "Details" button.
Click "Supply" button.
Enter the amount of the asset you would like to supply.
Click "Supply Asset"
If this is your first time supplying this asset you may be required to approve the asset transfer before the actual transfer (depending on the asset type).
Sign and send the transaction in your Wallet.
Wait for the transaction to be processed.
Once the transaction has gone through, you'll see your asset supply in "Your supplies".
Now, you can borrow assets against your collateral. Be careful only to borrow a little; otherwise, your position may be liquidated. The simplest metric for the position risk is the health factor.
Choose an asset to borrow and click "Borrow" button.
Enter the amount of the asset you would like to borrow. Pay attention to the Health Factor.
Click "Borrow Asset"
Sign and send the transaction in your Wallet.
Wait for the transaction to be processed.
Once the transaction has gone through, you'll see your asset borrowed in "Your borrows".
If you have significant borrowing positions, your ability to withdraw your supply may be restricted. You need to repay all your borrowed assets with interest to withdraw all your supplies.
Choose the asset to repay and click "Repay" button.
Enter the amount of the asset you would like to repay.
Click "Repay Asset"
If this is your first time repaying this asset you may be required to approve the asset transfer before the actual transfer (depending on the collateral type).
Sign and send the transaction in your Wallet.
Wait for the transaction to be processed.
Once the transaction has gone through, you'll see changes in "Your borrows".
Choose the asset to withdraw and click "Withdraw" button.
Enter the amount of the asset you would like to withdraw.
Click "Withdraw Asset"
Sign and send the transaction in your Wallet.
Wait for the transaction to be processed.
Once the transaction has gone through, you'll see changes in "Your supplies".
Pay attention to your Health Factor. If it becomes too small, your supplied assets may be liquidated to restore it. In that case, you will lose your supply.
There are 2 ways how to manage your Health Factors:
Supply more assets
Repay your borrowed assets

The VariableDebtToken contract is part of the Rasa Lending. It tracks users' borrowing positions at variable interest rates. This token is non-transferable and can only be minted or burned by the lending pool.
DEBT_TOKEN_REVISION: Version of the debt token.
_underlyingAsset: The address of the underlying asset.
POOL: Reference to the main Pool contract.
_incentivesController: Incentives controller for the token.
approveDelegation: Delegates borrowing power to a user.
delegationWithSig: Delegates borrowing power via signature.
setIncentivesController: Sets the incentives controller.
balanceOf: Returns the debt balance of a user.
totalSupply: Returns the total supply of the debt token.
borrowAllowance: Returns the borrow allowance for a user.
name: Returns the name of the token.
symbol: Returns the symbol of the token.

getIncentivesController: Returns the incentives controller address.
UNDERLYING_ASSET_ADDRESS: Returns the underlying asset address.
Mint/Burn Functions:
mint: Mints debt tokens to a user.
burn: Burns debt tokens from a user.
The following standard ERC20 functions are disabled as this is a non-transferable token:
transfer
allowance
approve
transferFrom
increaseAllowance
decreaseAllowance
These functions revert with an OPERATION_NOT_SUPPORTED error if called.
Mint: Emitted when tokens are minted.
Burn: Emitted when tokens are burned.
BorrowAllowanceDelegated: Emitted when borrow allowance is delegated.
Transfer: Emitted when tokens are transferred (disabled in this contract).
