According to Foresight News, cross-chain liquidity protocol Synapse Protocol has launched testnets for its Synapse Interchain Network and Synapse Chain. The Synapse Interchain Network is based on optimistic rollups, enabling trustless communication between chains, allowing applications to access all blockchain data and liquidity instantly. Synapse Chain, on the other hand, is an L2 solution built on the Syn OP stack, enabling deployed applications to access all interchain states.
