How to Bridge from Solana to Optimism

The process to bridge from Solana to Optimism requires the use of two cross-chain decentralized exchanges. This is because there are no direct bridges from Solana to Layer 2 protocols on Ethereum like Optimism. That said, the first bridge will take you from Solana to Ethereum, then the second bridge will move your assets from Ethereum to Optimism.

We recommend following the steps below to move your assets from Solana to Optimism in the cheapest way possible using these cross-chain bridges.

  1. Visit Portal Bridge and connect your Solana Wallet.
  2. Select Ethereum as your Destination Chain and select the tokens you want to transfer, then execute your transaction.
  3. Once your tokens arrive on Ethereum, visit the Optimism Bridge.
  4. Select Optimism as your Destination Chain and select the tokens you want to transfer, then execute your final transaction.
