Synapse is a blockchain protocol designed to enable interoperability. Much of this is achieved through its cross-chain messaging protocol, which supports both asset transfers and smart contract calls. As a result, different blockchains can exchange information with each other in a way that is both straightforward and secure. For instance, developers can build decentralized applications with Synapse, including cross-chain DEX, lending services, margining systems, derivatives markets, yield aggregators, and other application types.

Synapse’s native token is SYN. It has a maximum supply of 250000000 SYN and is used to move value within the Synapse ecosystem.

What are Synapse’s key features and how does it work?

At its core, Synapse functions as a base layer protocol. It includes three key parts: generalized cross-chain communication, an optimistic security model, and the synapse bridge. Generalized cross-chain communication is handled through Synapse’s messaging system. Arbitrary information can be transmitted between chains in a secure and seamless manner. This lets developers avoid deploying the same application on every blockchain-instead, they can deploy it once on a single chain. Then, Synapse’s messaging system can relay important data (including smart contract calls) between blockchains so the application can run across multiple networks.

In simple terms, Synapse’s optimistic approach assumes transactions are valid, while a set of off-chain participants submit and publish proofs for any transactions deemed malicious or fraudulent during an optimistic window, after which the transaction is finalized. The design is intended to make harmful behavior more expensive and harder, which in turn strengthens security.

The Synapse Bridge is a user-facing application built on top of the protocol’s communication network. It is the first app created with Synapse and enables users to swap assets between EVM and non-EVM blockchains. 

What can SYN be used for?

Synapse smart contracts can be used by development teams to build applications that are genuinely cross-chain compatible. This applies whether the target networks are base layers, roll-ups, or application-specific chains.
