How the swap works
-
Type the USDC amount and paste your Optimism payout address on Optimism mainnet.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast USDC to that deposit. After the required confirmations, OP is sent to your wallet.
Check these before you send
- ERC-20 USDC follows Ethereum confirmation times.
- Send USDC on Ethereum mainnet only for this route β not Polygon, Base, or Solana USDC.
- Leave ETH in your wallet for gas when sending USDC.
- If OP 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.
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 on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. L2 USDC is a different asset on-chain.
Gas fees apply to token transfers β ensure sufficient ETH balance.
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 not received?
Confirm your wallet is on Optimism mainnet and fully synced.
OP payout tips
- Payouts go to Optimism β 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
Does USDC to OP require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for USD Coin to Optimism.
How long until OP arrives?
Many orders finish in a few minutes. ERC-20 on Ethereum deposit confirmations and Optimism mainnet payout time set the wait.
Do you hold USDC or OP for me?
No. You send USDC from a wallet you control and OP is paid to the address you provide β PeakSwap does not keep a user wallet.
What if I send USDC on the wrong chain?
Use ERC-20 on Ethereum exactly as shown on the order. A wrong-network send may not be credited β read the swap safety notes first.
