How to Supply

When supplying take care to input the correct data. Make sure you are supplying to a wallet you can control on Pool Chain (Arbitrum).

You can supply any supported asset and earn interest across any chain through Replete by interacting with RepletePool . After supplying collateral, you are able to create borrow positions with supported assets or withdraw to a different chain.

The provided onBehalfOf will receive rTokens on Pool Chain and requires no user interaction.

From Any Chain

When supplying, ensure the RepletePool contract has enough allowance to spend funds on behalf of msg.sender for the amount being supplied.

To supply native token (if supported) through RepletePool, set the asset parameter as RepletePool.ETH_ADDRESS() and set amount as the intended supply 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)
