# Optimism Add your Optimism addresses to rotki to track OP and token balances, decoded transaction history, and DeFi activity. You choose which Optimism RPC endpoint handles the queries. ## Features - Native, ETH, and ERC-20 token balances tracked for your Optimism addresses. - Transactions decoded into readable events: swaps, transfers, bridges, and protocol interactions. - DeFi protocols decoded on Optimism, including Velodrome, Aave, Curve, Balancer, Uniswap, and more. - Superchain bridge deposits and withdrawals linked across Ethereum and Optimism. - Reuse an Ethereum address on Optimism in rotki. ## Setup 1. In rotki, open Blockchain & Accounts → Optimism → Add address. 2. Paste your address (you can reuse the same one you use on Ethereum). 3. Optional: in Settings → RPC, set your preferred Optimism RPC endpoint. ## FAQ ### Which Optimism RPC does rotki use? rotki is a local application that talks directly to the Optimism RPC endpoint you configure - the public default, a third-party provider, or your own node. The query goes from your computer to that endpoint without passing through any rotki-operated server. ### Can I track the same address on Ethereum and Optimism? Yes. Add it under both chains; rotki keeps balances and history separate per chain but lets you view a unified portfolio. ### Are L1-to-L2 bridge transactions decoded? Yes. rotki links the L1 deposit/withdrawal events with their counterpart on Optimism so your transfers are not double-counted.
