How Optimism → Ethereum routing works
Bridge ETH/USDC across Optimism and Ethereum L2s without leaving EVM — Ropil routes through bridge aggregators that solve this in seconds.
Ropil queries three independent protocols and uses whichever returns the best output amount in USD, accounting for slippage and network fees:
- LiFi aggregates bridges and DEXes across EVM chains. Typically deepest for Optimism ↔ Ethereum.
- Relay uses an intent / solver model. Often fastest (under 30 seconds) for stablecoin movements between EVM L2s.
- THORChain runs native cross-chain pools. Falls back to native-asset routing if LiFi and Relay both lack liquidity for Optimism ↔ Ethereum.
What you need
- A self-custodial wallet (MetaMask, Rabby, WalletConnect).
- ETH on Optimism to pay for the input + gas.
- A receiving address on Ethereum (your wallet handles this).
Before you click swap, read the risk disclosure — cross-chain swaps are irreversible and a bridge failure can strand funds.
