Firefly Bridge

Firefly Bridge is a trust-minimized cross-chain messaging and asset transfer protocol built for chain abstraction, spanning EVM and non-EVM networks without wrapped tokens or third-party custody. It uses a maker-based relay model: a user submits an intent on the source chain, a maker relays the calldata to the destination chain, and deterministic contracts on the destination side decide whether to execute. Makers never control user funds and face slashing and public visibility for misbehaviour.

Contracts share one address and one standardized interface across all EVM chains, transfers typically finalize within 2 to 30 seconds, and delays or failures trigger automatic refunds or fallback recovery. The protocol natively supports stablecoin transfers across 55 networks and multi-asset transfers across more than 70, and exposes primitives such as batch cross-chain calls, atomic cross-chain execution and abstraction-layer liquidity pools, with integrations into the Circle partner network and QuickNode multi-chain RPC.
