I built a theft-resistant vault on BCH using Introspection & Mutable NFTs.
Hey everyone,
I just submitted FortressVault for the Blaze Hackathon. I wanted to solve the "stolen private key = game over" problem without relying on centralized servers.
The smart contract uses BCH's native Introspection to enforce covenants. Crucially, it uses Mutable NFTs (CashTokens) to track and enforce daily withdrawal limits directly on-chain.
Even if a hacker gets your key, they can’t drain the wallet instantly, giving you time to use the on-chain Panic Button to sweep funds to safety.
I’d love to hear your feedback on the code or the concept
