Altitude
Summary
DeFi loans are typically over-collateralized and capital-inefficient, Altitude is a non-custodial protocol that optimizes DeFi loans. Altitude actively manages usersʼ debt and collateral in real-time, optimizing capital efficiency. When a user takes out a loan from the Altitude it will be optimized by: Continuously refinancing debt at the best available rates. Actively managing dormant capital to generate yield. Channeling the generated yield towards reducing user debt. Users can interact with the protocol through the following functions. These functions are run against a specific vault: Deposit - The deposit function allows a user to transfer the supply asset of the vault and receive supplyTokens in exchange. deposit(uint256 amount, address onBehalfOf) amount - the amount the user wants to deposit. The user must approve this amount prior to deposit. onBehalfOf - the address onBehalfOf who this deposit is made, typically the user themselves Upon receiving a deposit the vault will deploy this collateral into the active lending provider to be used as collateral. Borrow - User borrows the specified amount of borrow assets from the vault and receives borrowTokens in exchange to represent their debt. borrow(uint256 amount) amount - the amount the user wants to borrow Upon receiving a request for a borrow the vault will check how this request would affect the users position and if within specified margins will borrow the required amount from the active lending provider. Withdraw - User transfers supplyTokens and receives the vault supply assets in return withdraw(uint256 amount, address to)amount - amount the user wants to withdraw to - address to which the funds should be sent The user can withdraw up a loan-to-value ratio of the specified supplyThreshold. Repay - User transfers vault borrow assets to reduce their own debt or the debt of another user who has approved them to repay repay(uint256 amount, address onBehalfOf) amount - amount the user wants to withdraw onBehalfOf - address onBehalfOf who the loan should be repaid. Claim Rewards - For users who donʼt have a loan their yield rewards will accumulate directly to their account in the vault borrow asset. These can be withdrawn through the claimRewards function. claimRewards(uint256 amountRequested) amountRequested - amount the user wants to withdraw There are a number of other functions that can be utilized by users in specific scenarios. depositAndBorrow - combining deposit and borrow in a single transaction. repayAndWithdraw - combining repaying and withdrawing in a single transaction. commitUser - update an individual account, recognising earnings/losses from yield farming. liquidateUsers - liquidate one or more user unhealthy user positions. allowOnBehalf - allowing a users to authorize a specific address to act on its behalf borrowOnBehalfOf - a pre-approved user borrows assets on behalf of another user repayBadDebt - repaying bad debt for a user whoʼs supply token balance is 0.
