V1 Converters

On V1 Converters, the same value of both reserve assets need to be provided or removed. One LP token corresponds to a share of both reserve assets.

Adding Liquidity

addLiquidity increases the pool's liquidity and mints new LP tokens (shares in the pool) to the caller. The assets are to be provided in the same ratio as the pool holds them at the time of transaction execution. If the ratio differs, not all provided tokens will be transferred to the pool.

function addLiquidity(IERC20Token[] _reserveTokens, uint256[] _reserveAmounts, uint256 _minReturn) public payable protected active 

Arguments

Name	Type	Description
_reserveTokens	IERC20Token[]	address of each reserve token
_reserveAmounts	uint256[]	amount of each reserve token
_minReturn	uint256	minimum return amount of liquidity pool tokens

Removing liquidity

removeLiquidity decreases the pool's liquidity and burns the caller's shares in the pool.

function removeLiquidity(uint256 _amount, IERC20Token[] _reserveTokens, uint256[] _reserveMinReturnAmounts) public nonpayable protected active 

Arguments

Name	Type	Description
_amount	uint256	amount of liquidity pool tokens to burn in exchange for the underlying reserves.
_reserveTokens	IERC20Token[]	address of each reserve token
_reserveMinReturnAmounts	uint256[]	minimum return-amount of each reserve token
