The objective of this proposal is to do an upgrade of the credit manager contract which enables auto-repay of borrows after a swap action, within the same transaction.
Currently the repay function requires the user to pass in an exact amount to repay. However when swapping an asset, you cannot accurately calculate how much of the “swap to" asset you will receive once accounting for slippage etc.
This update allows a user to specify they would like to repay the available account balance amount of an asset instead of a specific amount.
Currently Mars enables the user to open a leveraged long or short position in one transaction. However to “close” this same position takes multiple transactions involving swapping assets and repaying debt on assets.
With this new change, users of Mars protocol will be able to close a margined trade position in one transaction via swapping from the current asset to the debt asset and repaying the account balance of the debt asset from within one transaction.
A UI upgrade is planned to accompany this smart contract upgrade that introduces an auto-repay toggle to the trading screen. If the user is swapping into an asset they have a debt balance of, they now have the option to auto-repay this debt in the same transaction.
This change introduces smart contract code changes, the risk in making changes to the smart contracts are that while the code changes are minor, new bugs or unforeseen situations as a result of the changes can occur.
This upgrade introduces a new functionality to the repay and repay_for_recipient functions that allow the amount of “account_balance” to be passed in the amount argument. Passing this value to the mentioned functions will repay the maximum amount possible based on the users account balance.
The changes can be viewed in Release v2.0.2 · mars-protocol/contracts · GitHub
This is a signaling proposal, not an executable proposal.
The Mars smart contracts on the Osmosis chain are currently controlled by the Builder Multisig address. If this proposal passes, the builders will utilize their multisig to make the necessary parameter changes.
