exchange.IO("abi", ...)

In the FMZ Quant Trading Platform, various blockchain-related functions are mainly implemented through the exchange.IO() function. The following documentation will describe the different functions of the exchange.IO() function separately. The exchange.IO("abi", ...) function call is used to register ABI.

• Supports Ethereum (eth)

• Supports TRON (tron)

    
    
    
exchange.IO(k, address, abiContent)

Examples

    javascript
    
    
function main() {
    // register Uniswap SwapRouter02 abi
    var routerAddress = "0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45"
    var abi = `[{"inputs":[{"components":[{"internalType":"bytes","name":"path","type":"bytes"},{"internalType":"address","name":"recipient","type":"address"},{"internalType":"uint256","name":"amountOut","type":"uint256"},{"internalType":"uint256","name":"amountInMaximum","type":"uint256"}],"internalType":"struct IV3SwapRouter.ExactOutputParams","name":"params","type":"tuple"}],"name":"exactOutput","outputs":[{"internalType":"uint256","name":"amountIn","type":"uint256"}],"stateMutability":"payable","type":"function"}]`

    // abi only uses partial exactOutput method content, complete abi can be searched online
    exchange.IO("abi", routerAddress, abi)
}

Arguments

Remarks

If the called smart contract method is a standard ERC20 method, registration is not required.

To obtain the contract's ABI content, you can use the following URL, just take the result field, for example:

            url
            
            
https://api.etherscan.io/api?module=contract&action=getabi&address=0x68b3465833fb72A70ecDF485E0e4C7bD8665Fc45
