HI everyone I saw an interesting contract depolyed on etherscan and want to simulate the behavior. how this input data (the first 4th bytes not method) can be sent to deployed contract? (I don't have abi)

Share contract link?

You can create a raw transaction something like this, sign it and broadcast via any rpc provider

var rawTx = {
nonce: '0x00',
gasPrice: '0x09184e72a000',
gasLimit: '0x2710',
to: '0x0000000000000000000000000000000000000000',
value: '0x00',
data: '0x7f7465737432000000000000000000000000000000000000000000000000000000600057'
}

Replace data with whatever data you need. Others please correct me if I'm wrong, haven't done much raw transactions
