Exchange in 3 steps
-
Set the ARB amount and paste your Optimism payout address on Optimism mainnet.
-
Create the order to lock the quote and see the deposit address.
-
Send ARB to that deposit. After confirmations, OP is paid to your wallet.
Before you broadcast
- Arbitrum confirmations are usually fast — often within a minute.
- Send ARB on Arbitrum One only — not Ethereum, Optimism, or Base unless your order says otherwise.
- Use an Arbitrum-compatible wallet and address (0x…). Leave enough ETH on Arbitrum for gas if needed.
- OP not visible yet? Wait a few minutes, resync your wallet, then contact support with your order ID if the payout tx is already listed.
Arbitrum — leading Ethereum rollup
ARB is the governance token of Arbitrum One — an optimistic rollup with EVM compatibility and wide DeFi adoption.
ARB on Arbitrum One
Use an Arbitrum One wallet for deposits. Other chains use different assets even with the same ticker.
Leave enough ETH on Arbitrum for gas on top of the swap amount when required.
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 not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- Payouts go to Optimism — verify your wallet RPC is set to Optimism, not Ethereum mainnet.
- Check Optimistic Etherscan with the payout tx hash from your order page.
- Allow a minute for your wallet to refresh after the explorer shows the transfer.

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