To bridge cryptocurrencies between any two networks you will need to use a secure bridging protocol. And before you use a bridging protocol you must have a Web3 Wallet extension added to your browser, if you don’t have one already we recommend using Metamask. Most bridging protocols allow access to Metamask, Binance Smart Chain Wallet, Coinbase Wallet and Wallet Connect.

Once you have added Metamask to your browser you will need to send funds to your account from your exchange wallet.

Where to Bridge Crypto from AVAX to OP

Synapse protocol is the most popular cryptocurrency bridging platform in the world due to its competitively low fees, fast transaction speeds and a large selection of networks. The exchange allows users to bridge across 15 different chains.
