​
Signature Hashes Explained

Each function and event has a unique identifier: Function signatures (4 bytes): 
transfer(address,uint256) → 0xa9059cbb
Event signatures (32 bytes): 
Transfer(address,address,uint256) → 0xddf252ad...
Claude automatically handles these - just describe what you’re looking for.

​
Tips

Be specific: “deposit” is clearer than “put money in”
Mention the contract—different protocols use different function names.

​
Limitations

Historical depth varies. Very old transactions may not be available.
Rate limits apply. Don’t query too frequently for the same data.
