Exchange in 3 steps
-
Set the OP amount and paste your Arbitrum payout address on Arbitrum One.
-
Create the order to lock the quote and see the deposit address.
-
Send OP to that deposit. After confirmations, ARB is paid to your wallet.
Before you broadcast
- Optimism confirmations are usually fast — often within a minute.
- Send OP on Optimism mainnet only — not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0x…). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- ARB not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Optimism — Ethereum L2 with low fees
OP is the governance token of Optimism — an Ethereum rollup with fast, low-cost transfers and deep Superchain liquidity.
OP on Optimism mainnet
Use an Optimism wallet for deposits. L1 Ethereum or other L2 sends may not be credited.
Leave enough ETH on Optimism for gas when moving OP or other tokens.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB not received?
Confirm your wallet is on Arbitrum One and fully synced.
ARB payout tips
- Payouts go to Arbitrum One — use a 0x-style address on the correct chain.
- Check Arbiscan with the payout tx hash if your balance has not updated.
- Do not expect ARB on Ethereum mainnet unless your order explicitly lists it.

Frequently asked questions
Is identity verification required to trade OP for ARB?
No. GetSwap is a NO-KYC & Privacy-First Crypto Exchange — no profile, no ID upload, and no funded account for Optimism → Arbitrum.
How long is a OP → ARB order?
Typical completion is a few minutes. Optimism mainnet and Arbitrum One confirmation times set the pace.
Do you custody OP or ARB?
No. You send OP yourself and ARB is paid to the address you enter — GetSwap does not keep a wallet balance for you.
What if I pick the wrong OP network?
Match the network printed on the order (Optimism mainnet). A mismatch can strand the deposit — check the swap safety notes first.
