Get multiple ETH transactions

Question

I'm a little new to Web3, and in NodeJS I'm trying to create a deposit-aware system. Today I'm doing the following:

ETH Transactions: Get it through getBlock, and check whether the "to" of the transaction belongs to me or not Transactions Tokens: Obtained through getPastEvents, as in the code below:

const events = await tokenContract.getPastEvents('Transfer', {
    filter: { to: walletsChunk },
    fromBlock,
    toBlock,
    maxBlockResults: 10000
});

So I have the following problems:

• For some reason, sometimes I have the impression that getPastEvents does not return all transactions, I don't know if it could be some address limit or block range, or even another error
• Performance, I have doubts if this is the best way to get transactions to verify they belong to me.
• The most critical thing is that this type of transaction exists: https://etherscan.io/tx/0x4bad5eceba8501b62b9307c002957eb2a9ac5eb4ee8bc39340c801eb2abc93da. I don't know how I can get this transaction, just having the address of a wallet which is present in the transaction

So to use eth_getBlockReceipts with web3.js, you need to use the extend method that allows you to basically 'extend' the class and use any RPC method.

Note that it only works in web3.js V1. It was deprecated in V4. So you need to install V1.9.0

npm i [email protected]   

Then you can use it like this:

/* 
eth_getBlockReceipts is not available in Web3.js
Create a custom class using web3.extend to implement it
*/

const Web3 = require("web3");
const NODE_URL = "CHAINSTACK_NODE_URL";
const web3 = new Web3(NODE_URL);

web3.extend({
    property: 'eth',
    methods: [{
      name: 'getBlockReceipts',
      call: 'eth_getBlockReceipts',
      params: 1,
      inputFormatter: [web3.extend.formatters.inputDefaultBlockNumberFormatter],
      outputFormatter: null
    }]
  });

async function getBlockReceipts(blockId) {
  const receipts = await web3.eth.getBlockReceipts(blockId)
  console.log(receipts)
}
  
getBlockReceipts("latest")

Just replace your node URL.

Remember, it only works on the Erigon client! Chainstack offers archive Erigon nodes on the Growth plan.

For free API's there's a limit of 1000 blocks . You can use alchemy's API if you think getblock isnt working. If your scope of work is only limited to finding out whether the to address belongs to you or not then i think this code is good . The transaction which you are viewing is of Coinbase and no events was emitted in this transaction i have checked on tenderly as well.
