Functions

`tradeWithHint`

Executes a trade between src and dest token and send dest tokens to destAddress; platform fee is ignored and is pre-Katalyst/backwards compatible.

function tradeWithHint(ERC20 src, uint256 srcAmount, ERC20 dest, address payable destAddress, uint256 maxDestAmount, uint256 minConversionRate, address payable walletId, bytes hint) external payable returns (uint256)

Parameter	Type	Description
`src`	ERC20	source ERC20 token contract address
`srcAmount`	uint256	source ERC20 token amount in its token decimals
`dest`	ERC20	destination ERC20 token contract address
`destAddress`	address	recipient address for destination ERC20 token
`maxDestAmount`	uint256	limit on the amount of destination tokens
`minConversionRate`	uint256	minimum conversion rate; trade is canceled if actual rate is lower
`walletId`	address	deprecated
`hint`	bytes	hint in bytes for reserve routing

Returns:
Amount of actual destination tokens in twei

`tradeWithHintAndFee`

Executes a trade between src and dest token and send dest tokens to destAddress; includes the platform fee.

function tradeWithHintAndFee(IERC20 src, uint256 srcAmount, IERC20 dest, address payable destAddress, uint256 maxDestAmount, uint256 minConversionRate, address payable platformWallet, uint256 platformFeeBps, bytes hint) external returns (uint256 destAmount)

Parameter	Type	Description
`src`	IERC20	source ERC20 token contract address
`srcAmount`	uint256	source ERC20 token amount in its token decimals
`dest`	IERC20	destination ERC20 token contract address
`destAddress`	address	recipient address for destination ERC20 token
`maxDestAmount`	uint256	limit on the amount of destination tokens
`minConversionRate`	uint256	minimum conversion rate; trade is canceled if actual rate is lower
`platformWallet`	address	address receiving the platform fee
`platformFeeBps`	uint256	platform fee in BPS to be used in this trade
`hint`	bytes	hint in bytes for reserve routing

Returns:
destAmount - Amount of actual destination tokens in twei

`trade`

Executes a Best-of-All trade (no reserve routing) between src and dest token and send dest tokens to destAddress; platform fee is ignored and is pre-Katalyst/backwards compatible.

function trade(IERC20 src, uint256 srcAmount, IERC20 dest, address payable destAddress, uint256 maxDestAmount, uint256 minConversionRate, address payable platformWallet) external returns (uint256)

Parameter	Type	Description
`src`	IERC20	source ERC20 token contract address
`srcAmount`	uint256	source ERC20 token amount in its token decimals
`dest`	IERC20	destination ERC20 token contract address
`destAddress`	address	recipient address for destination ERC20 token
`maxDestAmount`	uint256	limit on the amount of destination tokens
`minConversionRate`	uint256	minimum conversion rate; trade is canceled if actual rate is lower
`platformWallet`	address	address receiving the platform fee

Returns:
Amount of actual destination tokens in twei

`getExpectedRate`

Get the token conversion rate without platform fee; pre-Katalyst/backwards compatible.

function getExpectedRate(ERC20 src, contract ERC20 dest, uint256 srcQty) external returns (uint256 expectedRate, uint256 worstRate)

Parameter	Type	Description
`src`	ERC20	source ERC20 token contract address
`dest`	ERC20	destination ERC20 token contract address
`srcQty`	uint256	source ERC20 token amount in its token decimals

Returns:
expectedRate - conversion rate of the src and dest tokens after deducting the network fee. worstRate - 97% rate of the conversion rate, allowaing a 3% buffer for use in minConversionRate in trade.

`getExpectedRateAfterFee`

Get the token conversion rate after processing the hint and includes the platform fee.

function getExpectedRateAfterFee(IERC20 src, IERC20 dest, uint256 srcQty, uint256 platformFeeBps, bytes hint) external returns (uint256 expectedRate)

Parameter	Type	Description
`src`	IERC20	source ERC20 token contract address
`dest`	IERC20	destination ERC20 token contract address
`srcQty`	uint256	source ERC20 token amount in its token decimals
`platformFeeBps`	uint256	platform fee in BPS
`hint`	bytes	hint in bytes for reserve routing

Returns:
expectedRate - conversion rate of the src and dest tokens after deducting the network and platform fee.
