\_redeem ```solidity function _redeem(contract IERC20 token, uint256 amount, address to) internal returns (uint256 redeemed) ``` redeems funds from the pool ### Parameters | Name | Type | Description | | ------ | --------------- | -------------------------------------------------------------- | | token | contract IERC20 | the asset one is trying to redeem | | amount | uint256 | of assets one wishes to redeem | | to | address | is the address where the redeemed assets should be transferred | ### Return Values | Name | Type | Description | | -------- | ------- | ------------------------------------------------- | | redeemed | uint256 | the amount of asset that were transferred to `to` | ## \_supply ```solidity function _supply(contract IERC20 token, uint256 amount, address onBehalf, bool noRevert) internal returns (bytes32) ``` supplies funds to the pool ### Parameters | Name | Type | Description | | -------- | --------------- | ------------------------------------------------------------------------------------------------- | | token | contract IERC20 | the asset one is supplying | | amount | uint256 | of assets to be transferred to the pool | | onBehalf | address | address of the account whose collateral is being supplied to and which will receive the overlying | | noRevert | bool | does not revert if supplies throws | ### Return Values | Name | Type | Description | | ---- | ------- | ---------------------------- | | \[0] | bytes32 | reason for revert from Aave. | ## \_claimRewards ```solidity function _claimRewards(address[] assets, address to) internal returns (address[] rewardsList, uint256[] claimedAmounts) ``` rewards claiming. ### Parameters | Name | Type | Description | | ------ | ---------- | -------------------------------------------------- | | assets | address\[] | list of overlying for which one is claiming awards | | to | address | whom the rewards should be sent | ### Return Values | Name | Type | Description | | -------------- | ---------- | -------------------------------------------- | | rewardsList | address\[] | the address of assets that have been claimed | | claimedAmounts | uint256\[] | the amount of assets that have been claimed | ## checkAsset ```solidity function checkAsset(contract IERC20 asset) public view returns (bool) ``` verifies whether an asset can be supplied on pool ### Parameters | Name | Type | Description | | ----- | --------------- | --------------------------- | | asset | contract IERC20 | the asset one wants to lend | ### Return Values | Name | Type | Description | | ---- | ---- | ----------------------------------------- | | \[0] | bool | true if the asset can be supplied on pool | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
