Highlights

  • Co-built scanner: classifies six Bitcoin address types (P2PK through P2WSH) by quantum exposure
  • Address typing via bitcoinjs-lib and spent-status lookups via mempool.space Signet
  • Generates a migration plan for at-risk addresses

How it was built

At the MIT Bitcoin Expo hackathon our team built a Bitcoin security dashboard. I wrote the guardian engine, which sends a user's request to Claude and accepts only strict JSON naming one of eight wallet intents, with whitelist validation and a safe "unknown" default. I also wrote the Cogcoin integration that anchors guardian actions on chain. With a teammate, I co-built the quantum-exposure scanner, which types Bitcoin addresses with bitcoinjs-lib and looks up spent status on the Signet network. Teammates built the wallet and Lightning features, dashboard and deployment. Limits: rule-based scanner, not a model; not an autonomous agent.
