Synapse Protocol
Synapse Protocol is a cross-chain communications network enabling secure asset bridging and messaging across 16+ blockchains.

What is Synapse Protocol?
Synapse Protocol is a widely used, extensible, and secure cross-chain communications network. It provides 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 applications. Synapse Bridge, built on top of this infrastructure, lets users seamlessly transfer assets across 16+ blockchains including Ethereum, Arbitrum, Optimism, Base, Avalanche, BNB Chain, and Polygon. The bridge offers deep liquidity through cross-chain AMM pools, low-cost bridging, and developer-friendly integration for decentralized applications. Formerly known as Nerve Finance, Synapse has processed millions of transactions and tens of billions in bridged assets.
