Three steps on ToSwap
-
Set the USDC amount and paste the Optimism address that should collect payout on Optimism mainnet.
-
Tap Exchange to lock the live ToSwap quote and reveal this order’s deposit details.
-
Send exactly that USDC amount to the deposit. After ERC-20 on Ethereum confirms, OP is pushed to your wallet.
Before you broadcast
- ERC-20 USDC follows Ethereum confirmation times.
- Send USDC on Ethereum mainnet only for this route — not Polygon, Base, or Solana USDC.
- Leave ETH in your wallet for gas when sending USDC.
- If OP is late, refresh your wallet and re-check the order status. When a payout hash is already listed, email or SimpleX support with your Exchange ID — ToSwap has no login that can reopen expired pages.
USDC on ToSwap — ERC-20 unless stated
USD Coin on Ethereum mainnet is the default on this hub. A Solana or L2 USDC send will not credit an ERC-20 deposit — match the mint before you broadcast.
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 — ensure sufficient ETH balance.
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.
Deposit checklist
Chain mismatches and bad addresses are the usual failure modes — skim these notes before you fund the deposit.

More anonymous no-KYC lanes and chain notes for each coin.
FAQ for this route
Is KYC or a ToSwap account required for USDC → OP?
No. ToSwap never opens a profile or asks for ID documents on a standard USD Coin to Optimism order. You stay non-custodial on both legs.
How fast does OP usually arrive?
Many payouts leave within minutes after the ERC-20 on Ethereum deposit confirms. Congestion on ERC-20 on Ethereum or Optimism mainnet can stretch that — fees and mempools set the clock, not a manual review.
Does ToSwap hold my USDC or OP?
No hosted balance. You broadcast USDC from a wallet you control; OP is paid only to the address you paste. Nothing sits under a ToSwap username.
What if I send USDC on the wrong network?
Match ERC-20 on Ethereum exactly as printed on the order badge. A wrong-chain deposit often cannot be credited automatically — double-check before you broadcast.
