Functions
### `tradeWithHint` Makes a trade between src and dest token and send dest tokens to destAddress, with an additional `hint` parameter for reserve routing. Function is backwards compatible to pre-Katalyst.
function tradeWithHint(address payable trader, ERC20 src, uint256 srcAmount, ERC20 dest, address payable destAddress, uint256 maxDestAmount, uint256 minConversionRate, address payable walletId, bytes hint) external payable returns (uint256 destAmount) | Parameter | Type | Description | | --------- |:-----:|:-----------:| | trader | address | trader's address | | 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 | uint | minimum conversion rate; trade is canceled if actual rate is lower | | walletId | address | wallet address to send part of the fees to | | hint | bytes | for filtering permissionless reserves | Returns:\ destAmount - Amount of actual destination tokens
