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.

Build on Synapse Enter Bridge

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.

Widely integrated

Synapse is widely integrated across the most-used Layer 1 and Layer 2 networks for a seamless cross-chain experience.

How it all works

Smart contracts from one chain use the Synapse Messaging Router to send the message to the destination chain, where a corresponding Messaging Router sends it to the destination contract. Messages are optimistically verified to ensure security and trustlessness.
