Launched on August 28th, 2021, Synapse is a layered ∞ protocol that supports cross-chain assets transfer between various major blockchain networks and L2 sidechains. Currently, it supports token transfer between 12 networks. Apart from the bridging solution, the protocol allows you to swap assets and add liquidity. It has liquidity pools on almost every chain it supports where users can deposit tokens and earn rewards.

The AMM contract of the protocol was audited by Certik, OpenZeppelin, and Quantstamp. The Synapse Bridge contracts are currently undergoing multiple audits whereas the network validator code has not had an audit.

The Synapse protocol has a native token, named SYN that is used in its ecosystem. The token is used for governance voting, paying network fees, and as an incentive to the liquidity providers.

So, in this article, we will explain how you can use the Synapse bridge to transfer your assets from the Ethereum network to the Avalanche network.

Token In Metamask

If you are working with the desired output token for the first time, then you won’t be able to see the token in your wallet. You have to manually add the token contract address to see the token. Copy the contract address from the block explorer and add it to the Import Token-> Custom token field to view the token and its balance.
