# How to Repay {% hint style="danger" %} When repaying take care to input the correct data. Make sure you are repaying for the correct wallet. {% endhint %} You can repay any supported asset and close borrow positions across any chain through Replete by interacting with [RepletePool](/contracts/repletepool.md). Repaying an asset is often straight forward, where you supply the borrowed asset to repay debt positions. However, if interacting with [RepletePool](/contracts/repletepool.md), there are a few things to note, for example if there are excess assets provided for the repayment: * The default behavior is that excess assets are supplied to the pool on behalf of `onBehalfOf`. Allows for the user to withdraw the asset on any chain in another transaction. * `transferExtraAssets` is an option to allow for transferring the excess supplied assets to `onBehalfOf` on Arbitrum instead of doing the default behavior above. ### From Any Chain {% hint style="warning" %} When repaying, ensure the [RepletePool](/contracts/repletepool.md) contract has enough allowance to spend funds on behalf of `msg.sender` for the amount being repaid. {% endhint %} To repay native token (if supported) through [RepletePool](/contracts/repletepool.md), set the `asset` parameter as `RepletePool.ETH_ADDRESS()` and set `amount` as the intended repay amount. Ensure that `msg.value` covers the bridge transfer fee too. `msg.value` should equal `amount` + `bridgeFee`. If supplying native is not supported, the function will revert with error `Replete_UnsupportedAsset(address asset)` #### Interface #### Stargate v1 {% code fullWidth="true" %} ```solidity /** * @notice Repays a borrowed `amount` on a specific reserve, burning the equivalent debt tokens owned * - E.g.
