Synapse Protocol is **a cross-layer protocol that enables frictionless transactions between blockchains.** It uses multi-party computation validators, cross-chain AMMs, and SYN tokens.

Synapse is the most widely used, **extensible**, and secure **cross**-**chain communications network**. Preview your route in the Bridge panel, and connect your wallet when you're ready.
