How the swap works
-
Type the USDT amount and paste your USD Coin payout address on ERC-20 on Optimism.
-
Press Exchange to open the live quote and the deposit address for this order.
-
Broadcast USDT to that deposit. After the required confirmations, USDC is sent to your wallet.
Check these before you send
- ERC-20 USDT follows Ethereum confirmation times.
- Send USDT on Ethereum mainnet only β not Tron TRC-20.
- Leave ETH in your wallet for gas when sending ERC-20 USDT.
- 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.
Tether β USD-pegged stablecoin
USDT on Ethereum (ERC-20) is widely used in DeFi β send only on Ethereum mainnet.
USDT on Ethereum mainnet
Use an ERC-20 compatible Ethereum address. TRC-20 USDT is a different asset.
USD Coin on Optimism
Credit USDC only on ERC-20 on Optimism. A transfer on any other chain will not show up on this order.
When USDC arrives
Set your wallet to ERC-20 on Optimism.
If the order already lists a payout tx, wait a few minutes and resync before contacting support.

Frequently asked questions
Does USDT to USDC require KYC or an account?
No. PeakSwap does not ask for a profile, ID documents, or a hosted balance for Tether to USD Coin.
How long until USDC arrives?
Many orders finish in a few minutes. ERC-20 on Ethereum deposit confirmations and ERC-20 on Optimism payout time set the wait.
Do you hold USDT or USDC for me?
No. You send USDT 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 USDT 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.
