I can provide an article on how to detect whether Ethereum transactions belong to a specific Bitcoin address using the EIP-1559 script hash, which is a common method for identifying wallet balances.
Detecting Bitcoin Script Hashes in Ethereum Transactions
When tracking the wallet balance of specific Bitcoin addresses, detecting the corresponding EIP-1559 script hashes is crucial. The EIP-1559 script hash allows you to identify transactions that belong to specific Bitcoin wallets.
In this article, we will explore how to analyze the output script of the transaction to detect whether it belongs to a specific Bitcoin address using the EIP-1559 script hash.
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 executed on the Ethereum network, it includes a script that determines which wallet should receive the transaction output. This script is represented by an EIP-1559 script hash.
Analyzing the Transaction Output Script
To detect whether the output belongs to a specific Bitcoin address using the EIP-1559 script hash, you can analyze the transaction output script 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(address sender) public view returns (bytes32) {
// Extract the EIP-1559 script hash from the transaction output
bytes 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 {
// Extracts the expected EIP-1559 script hash for the given Bitcoin address
bytes memory expectedScriptHash = transactionOutput[index + 4];
uint256 expectedIndex = 0;
while (expectedIndex < expectedScriptHash.length && !bytes(3).eq(expectedScriptHash[expectedIndex], bytes(4).fromInt(0x...))) {
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 in tracking wallet balances. By analyzing the transaction output script and comparing it to 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 the EIP-1559 script hash. We also provided an example of a Solidity function that extracts and compares script hashes from transaction outputs.
