[Ethereum] Obtain token transfer data from an address

etherscanexplorersexternal-apitokens

I would like to obtain token transfer data from an address via Rest API

For example, take this address:
https://etherscan.io/address/0xfbb1b73c4f0bda4f67dca266ce6ef42f520fbb98#tokentxns

(Etherscan doesn't answer support questions about their API "because its free and presented as is", and they don't seem to have an API endpoint to show that same data.)

That link shows all of the token transfers for that address.

I would like to see all token transfers of X for that address. X being a token of my choice.

What is involved with obtaining that data via API?

How about using Etherscan's Event Log API?

https://api.etherscan.io/api?module=logs&action=getLogs
    &fromBlock=0
    &toBlock=latest
    &address=[Token Contract Address]
    &topic0=0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef
    &topic1=[From Address, padded to 32 bytes - optional]
    &topic2=[To Address, padded to 32 bytes - optional]

In the above topic0 is the signature of an ERC20 Transfer event.

For example, the following link shows you all the send transactions of LLL tokens from my account (two transactions).

Here, your X (the token) is represented by the token's contract address, which is easy enough to find out for the various tokens.

As always, the API will return you a maximum of 10000 results, so you may need to manage fromBlock and toBlock accordingly.

[Ethereum] Subscribe to all token transfers for entire blockchain

Ok, after quite some fight I found a solution

var Web3 = require('web3');

var web3 = new Web3('ws://127.0.0.1:8585');
console.log('Initiated');

// Track all the token transactions in whole blockchain
var subscription = web3.eth.subscribe('logs', { fromBlock: 1, topics: ["0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef"] }, function() {})
.on("data", function(trxData){
  function formatAddress(data) {
    var step1 = web3.utils.hexToBytes(data);
    for (var i = 0; i < step1.length; i++) if (step1[0] == 0) step1.splice(0, 1);
    return web3.utils.bytesToHex(step1);
  }

  console.log("Register new transfer: " + trxData.transactionHash);
  console.log("Contract " + trxData.address + " has transaction of " + web3.utils.hexToNumberString(trxData.data) + " from " + formatAddress(trxData.topics['1']) + " to " + formatAddress(trxData.topics['2']));
  //console.log(trxData);
  web3.eth.getTransactionReceipt(trxData.transactionHash, function(error, reciept) {
    console.log('Sent by ' + reciept.from + ' to contract ' + reciept.to);
  });
});

Script will output data in following format:

Register new transfer: 0x3bb3d83fa26560002cad0e920b78979eee5c5652a623f98cea5460dbb8d8fc94
Contract 0x0F5B3e7B0074F43c8C9C5324fabF83942c1FEf5c has transaction of 1 from 0x3cd40959e6fa78d4636cad472fdd4fa15d9867c7 to 0xd5142d2778f26471c1017f79687a91783636cfeb
Sent by 0xc270d8a6cf39b560c2746d4efdb24290fed76123 to contract 0x2c09402b4a1a42321160fd5af7737ca432e68c90

It contains ifo about who triggered the transfer, which contract was the main entry point of transaction, what is the token contract address, how many kones were transfered, from which address to which address and transaction hash.

You can now spy on the WHOLE blockchain! happy hacking!

[Ethereum] Get all TOKEN transactions by address

First, you go to your address page and click Erc20 Tokens Txns tab.

https://etherscan.io/address/0x9f7dd5ea934d188a599567ee104e97fa46cb4496#tokentxns

Then you look for Aragon in token column and click it.

You will end up on the page where you can export all your transactions in CSV.

And here is your URL structure:

https://etherscan.io/token/0x960b236a07cf122663c4303350609a66a7b288c0?a=0x9f7dd5ea934d188a599567ee104e97fa46cb4496

Just add you address as ?a=0x9f7dd5ea934d188a599567ee104e97fa46cb4496 URL parameter to Aragon token URL to get all Aragon transactions for your address.
