CommonActions

This abstract contract defines common actions to be used by the proxy actions contracts

State Variables

Address of the inheriting contract, used to check if the call is being made through a delegate call

address internal immutable _THIS = address(this);

Joins system coins into the safeEngine

function joinSystemCoins(address _coinJoin, address _dst, uint256 _wad) external delegateCall;

Parameters

Name	Type	Description
`_coinJoin`	`address`	Address of the CoinJoin contract
`_dst`	`address`	Address of the SAFE to join the coins into
`_wad`	`uint256`	Amount of coins to join [wad]

Exits system coins from the safeEngine

function exitSystemCoins(address _coinJoin, uint256 _coinsToExit) external delegateCall;

Parameters

Name	Type	Description
`_coinJoin`	`address`	Address of the CoinJoin contract
`_coinsToExit`	`uint256`	Amount of coins to exit [wad]

Exits all system coins from the safeEngine

function exitAllSystemCoins(address _coinJoin) external delegateCall;

Parameters

Name	Type	Description
`_coinJoin`	`address`	Address of the CoinJoin contract

Exits collateral tokens from the safeEngine

function exitCollateral(address _collateralJoin, uint256 _wad) external delegateCall;

Parameters

Name	Type	Description
`_collateralJoin`	`address`	Address of the CollateralJoin contract
`_wad`	`uint256`	Amount of collateral tokens to exit [wad]

Joins system coins into the safeEngine

Transfers ERC20 coins from the user to the proxy, then joins them through the CoinJoin contract into the destination SAFE

function _joinSystemCoins(address _coinJoin, address _dst, uint256 _wad) internal;

Exits system coins from the safeEngine

Exits system coins through the CoinJoin contract, transferring the ERC20 coins to the user

function _exitSystemCoins(address _coinJoin, uint256 _coinsToExit) internal virtual;

Joins collateral tokens into the safeEngine

Transfers ERC20 tokens from the user to the proxy, then joins them through the CollateralJoin contract into the destination SAFE

function _joinCollateral(address _collateralJoin, address _safe, uint256 _wad) internal;

Exits collateral tokens from the safeEngine

Exits collateral tokens through the CollateralJoin contract, transferring the ERC20 tokens to the user

The exited tokens will be rounded down to collateral decimals precision

function _exitCollateral(address _collateralJoin, uint256 _wad) internal;

Checks if the call is being made through a delegate call

modifier delegateCall();
