Introduction to Optimism on Ledger

Optimism is a leading Ethereum Layer-2 scaling solution that reduces gas fees by up to 10x while maintaining Ethereum-level security. By connecting your Ledger to Optimism, you gain:

• Enterprise-grade security for your Layer-2 assets
• Drastically lower fees (typically 
• 0.10−
• 0.10−0.50 per transaction)
• Full self-custody of OP Mainnet transactions
• Hardware-protected DeFi interactions
• Seamless bridging between Ethereum and Optimism

Note: While Ledger Live displays Optimism balances, full functionality requires connecting to a compatible wallet interface.
