To bridge from Optimism to Base, choose USDC, USDT or ETH on OP Mainnet (Optimism) as “from” and the token you want on Base as “to”, compare the routes and confirm. Both networks use 0x addresses, so funds arrive at the same address. On Base, gas is paid in ETH and tokens follow the ERC-20 standard.
