2

I could decode data for one transaction normally, but I can not for other. I am attaching both examples. I have no clue why the second one doesn't work because it seems I am doing the same yet it won't show token information. I would appreciate if anybody could take a look, compare both examples and if you see what could be wrong. I get INPUT_DATA from ethers function getTransaction.

Working example from this tx:

var ethers = require("ethers");
var abiDecoder = require('abi-decoder');

The first one is working because is an invocation of "multicall" function, that accepts a list of encoded input data for each of the call that should be done (as detailed in the smart contract source)

/// @param data The encoded function data for each of the calls to make to this contract

Then each input is passed to delegatecall function, so every encoded input is a complete call to a smart contract function.

So when you decode the input data of the 1st transaction, you get an array of encoded function calls, passing any of it to the decoder show you the decoded call.

The second one is not using encoded calls to make multiple call, but it's calling the "execute" function for each commands (first parameter)

/// @param commands A set of concatenated commands, each 1 byte in length

Then execute will call the dispatch function that will call internals function directly. Then input param contains only encoded inputs that will be passed to the command, and not a complete encoded function call
