AuthorizationUsed event does not expose from, to, value

[danielnordh]

When monitoring Transfer and AuthorizationUsed (transferWithAuthorization) events, it is made more difficult by the latter not including/exposing the from, to and value parameters in the same way as the former.

Transfer:

"returnValues": {
    "0": "0xD9d3768621774c3C357b9B5fcB23B5735eA2c7aE",
    "1": "0x53574F64F817290e622842462cc2B8708c1a3808",
    "2": "80000",
    "from": "0xD9d3768621774c3C357b9B5fcB23B5735eA2c7aE",
    "to": "0x53574F64F817290e622842462cc2B8708c1a3808",
    "value": "80000"
}

AuthorizationUsed:

"returnValues": {
    "0": "0xD9d3768621774c3C357b9B5fcB23B5735eA2c7aE",
    "1": "0x1f05761787aabb9d5e1b89e4572163db5ddd76c2e18bd8ccd78d46e6e18bcf09",
    "authorizer": "0xD9d3768621774c3C357b9B5fcB23B5735eA2c7aE",
    "nonce": "0x1f05761787aabb9d5e1b89e4572163db5ddd76c2e18bd8ccd78d46e6e18bcf09",
}

How do I get the from, to and value parameters from an AuthorizationUsed event?

[danielnordh]

For now, my workaround is to get the transaction, decode the inputs with this package and getting the from, to, value from there. But it's a lot of extra work to get to parity of information.

var inputDataDecoder = require('ethereum-input-data-decoder');

let tx = await web3.eth.getTransaction(txHash);
let decoder = new inputDataDecoder(USDC_ABI);
let decodedData = decoder.decodeData(tx.input);

let from = decodedData.inputs[0];
let to = decodedData.inputs[1];
let value = decodedData.inputs[2].toString();
