How to Get Gas on Optimism

Get ETH for gas on Optimism (OP Mainnet) instantly using USDC. No mainnet bridge fees. Swap from any chain via Telegram.

Optimism runs on ETH

Optimism (OP Mainnet) is one of Ethereum's leading Layer 2 networks. Every transaction is paid for in ETH — not OP. OP is the governance token; it does not pay gas. Fees are typically $0.01–0.05 per transaction, but with zero ETH in your wallet you can't transact at all.

The usual ways to get ETH on Optimism

Bridge from Ethereum mainnet using the Optimism Gateway — instant to deposit, but you pay mainnet gas ($5–15). Use a third-party bridge like Hop or Across — faster, but you still need gas on the source chain. Or withdraw ETH from a centralized exchange that supports Optimism, which means an account, verification, and a withdrawal fee.

Getting ETH on Optimism with fluel

1. Open the fluel Telegram bot and type /start.

2. Set your destination wallet: /setwallet 0xYourAddress

3. Deposit USDC to your fluel wallet from any chain you already use.

4. Type /gas 10 base optimism (swap $10 of USDC on Base into ETH on Optimism).

5. Type /confirm. ETH lands on Optimism in seconds — no source-chain gas required, because fluel covers the transaction fees.

How much ETH you need on Optimism

Optimism gas is cheap. $2–5 of ETH covers weeks of normal usage — swaps, transfers, NFT mints. Heavy DeFi users might keep $10–20. The ETH is delivered straight to your own wallet, so you can use it immediately with any dApp.
