Secure cross-chain communication

Synapse is the most widely used, extensible, secure cross-chain communications network. Build truly cross-chain applications using the Synapse Protocol.

Securely connect every blockchain

Synapse is comprised of a cross-chain messaging framework and an economically secure method to reach consensus on the validity of cross-chain transactions, enabling developers to build truly native cross-chain apps.

Extensible

Synapse's cross-chain messaging contracts can be deployed across any blockchain

Secure

Synapse employs an Optimistic security model to ensure integrity of cross-chain messages

Generalized

Any arbitrary data can be sent across chains including contract calls, NFTs, snapshots, and more

Powering the most popular bridge

Synapse Bridge is built on top of the cross-chain infrastructure enabling users to seamlessly transfer assets across all blockchains. The Bridge has become the most widely-used method to move assets cross-chain, offering low cost, fast, and secure bridging.
