I can provide you with an article on how to detect whether Ethereum transactions belong to a particular Bitcoin address using EIP-1559 script hashes, which is a common method for identifying wallet balances.
Detecting Bitcoin Script Hashes in Ethereum Transactions
When tracking the wallet balances of given Bitcoin addresses, detecting the corresponding EIP-1559 script hashes is crucial. EIP-1559 script hashes allow you to identify transactions that belong to specific Bitcoin wallets.
In this article, we will explore how to parse the output of a transaction script to detect whether it belongs to a given Bitcoin address using EIP-1559 script hashes.
Understanding Ethereum Script Hashes
Ethereum script hashes are used as identifiers for transactions. The most common script hash is 0x… (where … represents the hexadecimal value of the script hash).
When a transaction is made on the Ethereum network, it includes a script that determines which wallet should receive the transaction output. This script is represented by the EIP-1559 script hash.
Parsing a Transaction Script Output
To find out if the output belongs to a specific Bitcoin address using the EIP-1559 script hash, you can parse the transaction script output as follows:
- Extract the EIP-1559 script hash from the transaction output.
- Compare the extracted EIP-1559 script hash with the expected script hash for the given Bitcoin address.
Here is an example of how to do this in Solidity:
pragma solidity ^0.8.0;
contract TransactionParser {
function getScriptHash(senderAddress) public view return (bytes32) {
// Extract the EIP-1559 script hash from the transaction output
byte memory output = transactionoutput;
uint256 index = 0;
while (index < output.length && !bytes(3).eq(output[index], bytes(4).fromInt(0x...))) {
index++;
}
if (index == output.length) {
// No matching EIP-1559 script hash found
return bytes32(0);
} else {
// Extract the expected EIP-1559 script hash for the given Bitcoin address
bytes memory expectedScriptHash = transactionOutput[index + 4];
uint256 expectedIndex = 0;
while (expectedIndex expectedIndex++;
}
// Compare the extracted EIP-1559 script hash with the expected script hash
return bytes32(uint256(index + 8) % 65536 == uint256(expectedIndex) ? expectedScriptHash : bytes32(0));
}
}
}
Conclusion
Detecting Bitcoin script hashes in Ethereum transactions is a crucial step for monitoring wallet balances. By parsing the transaction output script and comparing it with the expected EIP-1559 script hash, you can identify whether the output belongs to a specific Bitcoin address.
In this article, we explored how to detect whether Ethereum transactions belong to a specific Bitcoin address using EIP-1559 script hashes. We also provided an example Solidity function that extracts and compares script hashes in transaction output.
