Optimism (OP Mainnet)

This article will help you set up your first Ledger Optimism (OP Mainnet) account.

You can manage, send, and receive ETH, OP and 100+ ERC20 tokens on the Optimism (OP Mainnet) blockchain. Since Optimism (OP Mainnet) accounts are fully supported in Ledger Live, you can directly deposit ETH, OP, and ERC20 tokens into your Ledger Optimism account without the necessity of bridging your assets from the Ethereum mainnet.
