I can provide you with an article on how to determine if an Ethereum transaction belongs to a specific Bitcoin address using the EIP-1559 script hash, which is a common method of determining wallet balances.
Detection of Bitcoin script hashes in Ethereum transactions
When tracking the wallet balance of given Bitcoin addresses, the determination of the corresponding hashes of the EIP-1559 script is crucial. The EIP-1559 script hash allows you to identify transactions that belong to specific Bitcoin wallets.
In this article, we will look at how to analyze the output script of a transaction to determine whether it belongs to a given Bitcoin address using the script hash EIP-1559.
Understanding Ethereum Script Hashes
Ethereum script hashes are used as transaction identifiers. The most common script hash is 0x… (where … is 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 the hash of the EIP-1559 script.
Analysis of the transaction output script
To determine if the output belongs to a particular Bitcoin address using the EIP-1559 script hash, you can analyze the transaction output script as follows:
- Extract the hash of the EIP-1559 script from the transaction output.
- Compare the extracted hash of the EIP-1559 script with the expected hash of the script for the given Bitcoin address.
Here’s an example of how to do it in Solidity:
`solidity
pragma solidity ^0.8.0;
contract TransactionParser {
function getScriptHash(address sender) public view returns (bytes32) {
// Extract the hash of the EIP-1559 script 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) {
// Corresponding hash of script EIP-1559 not found
return bytes32(0);
} else {
// Extract the expected hash of the EIP-1559 script for the specified 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 hash of the script EIP-1559 with the expected hash of the script
return bytes32(uint256(index + 8) % 65536 == uint256(expectedIndex) ? expectedScriptHash : bytes32(0));
}
}
}

Conclusion
Detecting Bitcoin script hashes in Ethereum transactions is an important step for tracking wallet balances. By analyzing the output script of the transaction and comparing it with the expected hash of the EIP-1559 script, it is possible to determine whether the output belongs to a particular Bitcoin address.
In this article, we looked at how to determine whether an Ethereum transaction belongs to a given Bitcoin address using the hash of the EIP-1559 script. We also provided an example of a Solidity function that extracts and compares script hashes in transaction output.
