// key findings

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.

🔐

You'll be asked for 2 credentials: SOLANA_PRIVATE_KEY, WALLET_PRIVATE_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.
