In this guide, we will outline the best method to bridge between Avalanche network and Optimism and how you can do it.

Summary: To bridge your assets between Avalanche and Optimism, you will need a Web3 wallet like MetaMask or Trust Wallet and a secure cross-chain bridge. With this method, you can transfer tokens like ETH, USDC or USDT across different protocols quickly and with low fees.

We recommend using Synapse protocol, a safe multi-chain bridge that allows users to transfer assets across sixteen networks, which include Avalanche and Optimism, as well as other EVM-compatible networks.

Avalanche to Optimism Bridging Fees

Bridging between Avalanche and Optimism is relatively cheap because both platforms use a proof-of-stake consensus model which enables low-fee transactions. We expect users to pay on average between $5-$10 to swap any available token between both networks. That said, we recommend using USDC to bridge because it typically has the lowest slippage and lowest fees.


There are many bridging protocols for moving assets across Avalanche and Optimism blockchains. Synapse protocol bridge is the most affordable and secure way to bridge instantly. With over $10 billion in bridging volume, the protocol has proven to be the best choice for users.
