Synapse (SYN) is an interoperability protocol that strives to facilitate the transfer of data across different blockchains. It enables users to move and swap their assets across various chains, including layer 1, layer 2, and sidechain ecosystems. The Synapse ecosystem comprises six components: the Synapse Bridge technology, the cross-chain AMM, aggregative cross-chain communication, the SYN token, the Synapse Chain, and optimistic security approaches. The Synapse Bridge strives to enable users to swap on-chain assets across multiple EVM and non-EVM blockchains. The SYN token powers the entire Synapse ecosystem, and the Synapse Chain is an Ethereum-based optimistic rollup designed to serve as a sovereign execution environment for cross-chain use cases.

Synapse operates using a stableswap algorithm to strive to facilitate the transfer of users' assets between different ecosystems while maintaining slippage, liquidity pool balances, and transaction prices. Its generalized messaging system aims to send any arbitrary data across chains. This means applications no longer have to be separately deployed across multiple blockchains; they can be deployed on a single chain and communicate with other chains to create the same user experience from one central application layer. The Synapse Chain offers developers a generalized smart contract interface for building natively cross-chain use cases by leveraging Synapse’s cross-chain messaging system. Applications built on Synapse Chain can execute their business logic across any blockchain.

Synapse seeks to enhance the interoperability of blockchains, allowing users to move their assets between different networks more efficiently. This can be particularly useful for decentralized applications (dApps) that need to operate across multiple blockchains. The Synapse Bridge technology strives to enable users to swap on-chain assets across multiple blockchains. This can be beneficial for users who want to take advantage of different features or opportunities available on different blockchains. Additionally, the Synapse Chain offers a platform for developers to build natively cross-chain use cases, expanding the potential applications of blockchain technology.

Synapse, based in Singapore, is the rebranding of Nerve Finance, the first stableswap AMM on the BNB Smart Chain (BSC). In August 2021, the project rebranded to Synapse Protocol and modified its business model, but it kept its key investors, including Three Arrows Capital, CMS Holdings, Alameda Research, Immutable Capital, Primitive Ventures, DeFiance Capital, and Mechanism Capital. The Synapse community governs its protocol through a decentralized group of SYN holders, known as the SynapseDAO. Community members guide the protocol’s development by voting and participating in governance activities. As of March 2023, there are 139,773,376 SYN in circulation.
