CompoundV2 adapter

CompoundV2 has one pool per each asset, so there is one adapter per cToken.

State-changing functions

`mint`

Deposits the specified amount of underlying to mint cTokens.

function mint(uint256 amount) external returns (uint256 tokensToEnable, uint256 tokensToDisable);

Parameter	Description
amount	Amount of underlying to deposit.

Usage:

import {ICompoundV2_CTokenAdapter} from "@gearbox-protocol/integrations-v3/contracts/interfaces/compound/ICompoundV2_CTokenAdapter.sol";
 
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = MultiCall({
    target: compoundAdapter,
    callData: abi.encodeCall(ICompoundV2_CTokenAdapter.mint, (amount))
});
 
creditFacade.multicall(calls);

`mintDiff`

Deposits the difference between the current balance of underlying and leftoverAmount, to mint cTokens.

function mintDiff(uint256 leftoverAmount) external returns (uint256 tokensToEnable, uint256 tokensToDisable);

Parameter	Description
leftoverAmount	Amount of underlying to keep on the account.

Usage:

import {ICompoundV2_CTokenAdapter} from "@gearbox-protocol/integrations-v3/contracts/interfaces/compound/ICompoundV2_CTokenAdapter.sol";
 
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = MultiCall({
    target: compoundAdapter,
    callData: abi.encodeCall(ICompoundV2_CTokenAdapter.mintDiff, (leftoverAmount))
});
 
creditFacade.multicall(calls);

`redeem`

Burns a specified amount of cTokens to receive underlying.

function redeem(uint256 amount) external returns (uint256 tokensToEnable, uint256 tokensToDisable);

Parameter	Description
amount	Amount of cTokens to burn.

Usage:

import {ICompoundV2_CTokenAdapter} from "@gearbox-protocol/integrations-v3/contracts/interfaces/compound/ICompoundV2_CTokenAdapter.sol";
 
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = MultiCall({
    target: compoundAdapter,
    callData: abi.encodeCall(ICompoundV2_CTokenAdapter.redeem, (amount))
});
 
creditFacade.multicall(calls);

`redeemDiff`

Burns the difference between the current balancer of cTokens and leftoverAmount, to receive underlying.

function redeemDiff(uint256 leftoverAmount) external returns (uint256 tokensToEnable, uint256 tokensToDisable);

Parameter	Description
leftoverAmount	Amount of cTokens to keep on the account.

Usage:

import {ICompoundV2_CTokenAdapter} from "@gearbox-protocol/integrations-v3/contracts/interfaces/compound/ICompoundV2_CTokenAdapter.sol";
 
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = MultiCall({
    target: compoundAdapter,
    callData: abi.encodeCall(ICompoundV2_CTokenAdapter.redeemDiff, (leftoverAmount))
});
 
creditFacade.multicall(calls);

`redeemUnderlying`

Burns cTokens to receive a specified amount of underlying.

function redeemUnderlying(uint256 amount) external returns (uint256 tokensToEnable, uint256 tokensToDisable);

Parameter	Description
amount	Amount of underlying received.

Usage:

import {ICompoundV2_CTokenAdapter} from "@gearbox-protocol/integrations-v3/contracts/interfaces/compound/ICompoundV2_CTokenAdapter.sol";
 
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = MultiCall({
    target: compoundAdapter,
    callData: abi.encodeCall(ICompoundV2_CTokenAdapter.redeemUnderlying, (amount))
});
 
creditFacade.multicall(calls);

Compound Multicaller library

The CompoundV2 adapter has a corresponding library that simplifies the MultiCall building API.

Usage example:

import {CompoundV2_Multicaller, CompoundV2_Calls} from "@gearbox-protocol/integrations-v3/test/multicall/compound/CompoundV2_Calls.sol";
...
 
using CompoundV2_Calls for CompoundV2_Multicaller;
...
 
MultiCall[] memory calls = new MultiCall[](1);
calls[0] = CompoundV2_Multicaller(compoundAdapter).mint(amount);
 
creditFacade.multicall(calls);
