Quick Take Synapse is a cross-chain interoperability protocol that enables composability across different chains. The Synapse bridge leverages the protocol to enable cross-chain asset swaps and transfers. Synapse’s V2 upgrade introduces optimistic verification and the Synapse chain, which is an Ethereum-based optimistic rollup. Synapse’s native token, SYN, will be used to secure the chain and incentivize optimistic verification participants.
