params	ExactInputSingleParams	address of token A, pool, amount of token A to swap, minimum amount of token B after the swap and data required by the pool for the swap

Returns

Name	Type	Description
amountOut	uint256	amount of token B after swap

exactInput

function exactInput(ExactInputParams calldata params) public payable returns (uint256 amountOut)

Swaps token A to token B indirectly by using multiple hops.

Parameters

Name	Type	Description
params	ExactInputSingleParams	address of token A, pool, amount of token A to swap, minimum amount of token B after the swap and data required by the pool for the swap

Returns

amountOut	uint256	amount of token B after swap

exactInputSingleWithNativeToken

function exactInputSingleWithNativeToken(ExactInputSingleParams calldata params) public payable returns (uint256 amountOut)

Returns

Name	Type	Description
amountOut	uint256	amount of token B after swap

exactInputWithNativeToken

function exactInputWithNativeToken(ExactInputParams calldata params) public payable returns (uint256 amountOut)

Swaps token a to token B indirectly by using multiple hops; it is the same as exactInput except it takes raw ERC-20 tokens from the users and deposits them into bento.

Parameters

Name	Type	Description
params	ExactInputSingleParams	address of token A, pool, amount of token A to swap, minimum amount of token B after the swap and data required by the pool for the swap

Returns

Name	Type	Description
amountOut	uint256	amount of token B after swap

complexPath

function complexPath(ComplexPathParams calldata params) public payable

Swaps multiple input tokens to multiple output tokens using multiple paths, in different percentages.

Parameters

Name	Type	Description
params	ComplexPathParams	includes all info needed for the swap

addLiquidity

function addLiquidity(
        TokenInput[] calldata tokenInput,
        address pool,
        uint256 minLiquidity,
        bytes calldata data
    ) public payable returns (uint256 liquidity)

Adds liquidity to a pool.

Parameters

Name	Type	Description

pool	address	address of pool to add liquidity to
minLiquidity	uint256	minimum output liquidity (caps slippage)
data	bytes	data required by pool to add liquidity

Returns

Name	Type	Description
liquidity	uint256	amount of liquidity added to chosen pool

burnLiquidity

function burnLiquidity(
        address pool,
        uint256 liquidity,
        bytes calldata data,
        IPool.TokenAmount[] calldata minWithdrawals
    ) public payable

Burns liquidity tokens to get back bento tokens.

Parameters
