Optimism RPC Information

To view the newly bridged funds on your Optimism Web 3 Wallet, you will need to add the RPC information. This will allow your Wallet to pick up and scan the Optimism network to update you with how much funds you have in your account.

The Optimism RPC is as follows:

  • Network name: Optimistic Ethereum
  • RPC URL:
  • Chain ID: 10

Is AVAX or Optimism better?

AVAX is a more secure chain because they are their own base network and L1 with thousands of network validators. Optimism as a L2 network are still quite centralized, but will be airdropping a token soon to help distribute governance.

Optimism currently presents an exciting opportunity because they will be the first L2 to airdrop a token and announce an incentives program. This will bootstrap the network in the same way Avalanche Rush did for AVAX.

To bridge from Avalanche AVAX to Optimism, the Synapse Protocol is the recommended cross-chain DEX for fast and affordable transfers of tokens like ETH, USDC, and USDT.
