Notice: For Sets created after June 2022 using TokenSets UI, please refer to the Batch Trading section on how to execute trades manually via Etherscan

What is the TradeModule:

The Trade Module enables managers of SetTokens to perform atomic trades using aggregators such as 0x and 1inch, and decentralized exchanges such as Sushiswap and Uniswap. This rebalances the Set for all Set holders.

Initializing the TradeModule:

All modules need to be added to the SetToken as the first step. Learn how to add a module to your SetToken by referring to the Adding a Module guide.

Once you have added the TradeModule to the SetToken, you must initialize the SetToken on the TradeModule:

/**
 * Initializes this module to the SetToken. Only callable by the SetToken's manager.
 *
 * @param _setToken        Instance of the SetToken to initialize
 */
function initialize(ISetToken _setToken);

Trading:

Only the manager will be able to trade. Call the trade function with inputs as follows:

Important: sendQuantity and _minReceiveQuantity are denominated in position units and not the notional quantity. For example, if 1 SetToken contains 1 WETH, and there are 10 supply of SetTokens (10 WETH locked in total), trading 100% of the ETH to DAI requires passing in 1 (more accurately 10**18) into the sendQuantity.

/**
 * Executes a trade on a supported DEX. Only callable by the SetToken's manager.
 * @dev Although the SetToken units are passed in for the send and receive quantities, the total quantity
 * sent and received is the quantity of SetToken units multiplied by the SetToken totalSupply.
 *
 * @param _setToken             Instance of the SetToken to trade
 * @param _exchangeName         Human readable name of the exchange in the integrations registry
 * @param _sendToken            Address of the token to be sent to the exchange
 * @param _sendQuantity         Units of token in SetToken sent to the exchange
 * @param _receiveToken         Address of the token that will be received from the exchange
 * @param _minReceiveQuantity   Min units of token in SetToken to be received from the exchange
 * @param _data                 Arbitrary bytes to be used to construct trade call data
 */
function trade(
    ISetToken _setToken,
    string memory _exchangeName,
    address _sendToken,
    uint256 _sendQuantity,
    address _receiveToken,
    uint256 _minReceiveQuantity,
    bytes memory _data
);

The exchange name is a string specifying which exchange adapter to execute the trade. The exchange name is registered in the IntegrationRegistry contract. Exchanges and aggregators currently supported by the TradeModule are:

Mainnet

Contract	Exchange Name
0x	ZeroExApiAdapterV4
1Inch	OneInchExchangeAdapter
Uniswap V2	UniswapV2ExchangeAdapter
SushiSwap	SushiswapExchangeAdapter
Kyber	KyberExchangeAdapter
Uniswap V3	UniswapV3ExchangeAdapter
Kyber DMM	KyberV3ExchangeAdapter
AMMSplitter	AMMSplitterExchangeAdapter

The _data parameter is optional on some exchanges and required for others. For example, you will need to input the trade calldata fetched from the 0x API or 1inch API to execute an 1Inch trade or custom path to route the trade through Uniswap or Sushiswap. For information on how to generate the custom _data parameter, check out the next few sections.
