Fiamma
The first-ever trust-minimized Bitcoin bridge.
About
Fiamma is building a trustless, ZK-powered Bitcoin infrastructure aimed at unlocking Bitcoin’s full potential for decentralized finance (DeFi), payments, and cross-chain interoperability. By leveraging BitVM2 and zero-knowledge proofs (ZKPs), Fiamma transforms Bitcoin from a passive store of value into an active participant in decentralized applications (dApps) and the broader decentralized internet.
Key Features
-
Fiamma Bridge
The first trust-minimized Bitcoin bridge powered by BitVM2, allowing users to bridge Bitcoin to other ecosystems like Arbitrum, ZKsync, and BOB without trusted intermediaries or custodians. -
Fiamma Layer
The first ZK verification layer on Bitcoin, enabling fast, scalable, and decentralized proof verification directly on Bitcoin’s base layer. -
BitVM2 Integration
Fiamma implements the smallest and most efficient ZKP verifier on Bitcoin, reducing Groth16 proof verification size from ~7 GB to ~1.3 GB, dramatically improving Bitcoin’s computational flexibility. -
Yield Opportunities for BTC Holders
Bitcoin liquidity providers can earn trustless yields by supplying BTC liquidity into the Fiamma Bridge ecosystem. -
High Throughput, Secure Bridging
Through optimistic ZK verification, Fiamma enables secure, efficient, and decentralized bridging of Bitcoin across chains—without relying on "wrapped BTC" models.
