Events

Erc20Supplied(liquidityProvider, asset, tokenAmount, cTokenAmount) CErc20Supplied(liquidityProvider, cAsset, cTokenAmount) Erc20Withdrawn(liquidityProvider, asset, tokenAmount, cTokenAmount) CErc20Withdrawn(liquidityProvider, cAsset, cTokenAmount ) EthSupplied(liquidityProvider, amount, cTokenAmount); EthWithdrawn(liquidityProvider, amount, cTokenAmount);

Details

getCAsset(asset) -> address Returns the address of the cAsset associated to the underlying asset.

getCAssetBalance(account, cAsset) -> uint256 Returns the cAsset balance of an account. This can be combined with cAssetAmountToAssetAmount() to get the accounts underlying balance.

supplyErc20(asset, amount) -> uint256

Returns the amount of cTokens minted and added to the lenders balance.

Emits a Erc20Supplied() event.

supplyCErc20(cAsset, amount) -> uint256

Returns the amount of cTokens added to the lenders balance.

Emits a CErc20Supplied() event.

withdrawErc20(asset, amount) - uint256

Returns the amount of cTokensburnedand subtracted from the lenders balance.

Emits a Erc20Withdrawn() event

withdrawCErc20(cAsset, amount) - uint256

Returns the amount of cTokens subtracted from the lenders balance.

Emits a CErc20Withdrawn() event.

supplyEth() - > uint256

Returns the amount of cTokens minted and added to the lenders balance.

Emits a EthSupplied() event.

withdrawEth(amount) -> uint256

Returns the amount of cTokensburnedand subtracted from the lenders balance.

Emits a EthWithdrawn() event.

assetAmountToCAssetAmount(asset, amount) -> uint256 Returns the amount of cAsset to be expected in a conversion from an underlying amount.

cAssetAmountToAssetAmount(cAsset, amount) -> uint256

Returns the amount of asset to be expected in a conversion from a cAsset amount. This function rounds at the 10th decimal and provides a slightly rounded, less-than-whole-number value. This results from Compound's cTokens having 8 decimal values.
