How the swap works
-
Type the OP amount and paste your USD Coin payout address on ERC-20 on Ethereum.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast OP to that deposit. After the required confirmations, USDC is sent to your wallet.
Check these before you send
- Optimism confirmations are usually fast β often within a minute.
- Send OP on Optimism mainnet only β not Ethereum, Base, or Arbitrum unless your order says otherwise.
- Use an Optimism-compatible wallet and address (0xβ¦). Leave enough ETH on Optimism for gas if sending ERC-20 tokens.
- If USDC has not appeared yet, wait a few minutes and refresh the wallet. When the order already shows a payout tx, contact support with your order ID.
Optimism β Ethereum L2 with low fees
OP is the governance token of Optimism β 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.
USD Coin β issued dollar stablecoin
USDC on Ethereum mainnet is a widely trusted stablecoin for DeFi and transfers β always use ERC-20 on Ethereum unless stated otherwise.
USDC not credited?
Verify your wallet is on Ethereum mainnet and the token contract matches official USDC on Ethereum.
When will USDC arrive?
ERC-20 USDC payouts follow Ethereum block times β usually minutes after your deposit confirms.
- Confirm your wallet is set to Ethereum mainnet, not Polygon, Base, or another L2.
- Add the official USDC token contract in your wallet if the balance does not appear automatically.
- Check the payout tx hash on Etherscan if your wallet shows no incoming transfer.
Why traders swap into USDC
USDC is widely used in DeFi and on exchanges that prefer a regulated dollar stablecoin.
On Ethereum mainnet it pairs naturally with ETH gas and most ERC-20 trading pairs.

Frequently asked questions
Does OP to USDC require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for Optimism to USD Coin.
How long until USDC arrives?
Many orders finish in a few minutes. Optimism mainnet deposit confirmations and ERC-20 on Ethereum payout time set the wait.
Do you hold OP or USDC for me?
No. You send OP from a wallet you control and USDC is paid to the address you provide β PeakSwap does not keep a user wallet.
What if I send OP on the wrong chain?
Use Optimism mainnet exactly as shown on the order. A wrong-network send may not be credited β read the swap safety notes first.
