What Is Synapse?
Synapse is a universal cross-chain protocol that enables the transfer of simple messages and complex data across different chains. The protocol supports cross-chain asset movements, smart contract calls, and NFTs. Developers can use Synapse to build cross-chain applications such as AMMs, lending platforms, derivative markets, and yield aggregators.
Background
Synapse started as a stable swap protocol on the BNB Chain called Nerve and evolved into a cross-chain bridge. The protocol currently supports 17 chains and has experienced $12.4 billion in total bridge volume since its inception. Synapse is known for its features, which include multiple transaction types, an optimistic security model, access to the Cosmos ecosystem, a developer toolkit, and the Synapse Chain.
How It Works
Synapse’s architecture consists of the Synapse Chain and the Cross-Chain Message Passing system. The Synapse Chain is an Optimistic Rollup of Ethereum that acts as a single execution layer for cross-chain applications. The Cross-Chain Message Passing system is secured via optimistic verification, where off-chain actors observe cross-chain transactions and submit fraud proofs if a malicious transaction is detected. The system involves Notaries, Broadcasters, Guards, and Executors. Synapse also offers certain security features such as audits, optimistic verification, governance, and slashing for malicious behavior.
