SIMULATE BEFORE YOU SIGN · LIVE WALKTHROUGH

One API call decides: approve, warn, or block.

Three real-world transaction shapes, run through the TxShield pre-flight check. Every verdict below is what your wallet or bot receives before the transaction is broadcast — while there is still time to stop it.

Put this verdict in your product.

One POST request per transaction. Your first 1,000 checks a day are free — no card required, pay-as-you-go after that.
