MATIC → Optimism

Swap USDC to USDT

Exchange USDC on Polygon PoS for USDT on OP Mainnet. Both assets reference USD, but they are separate tokens with different designs and liquidity. A quote can return more or less than one USDT per USDC.

USDC (Polygon) to Tether (Optimism)

You send: USDC (Polygon)USDC · MATIC
You receive: Tether (Optimism)USDT · Optimism

Enter your amount to check live availability for USDC on MATIC → USDT on Optimism. A provider quote is required before you can create a swap.

Address and network checks

Both Polygon PoS and OP Mainnet use EVM-style addresses. An identical address string cannot confirm the network. Check Polygon PoS in the sending wallet and OP Mainnet in the receiving wallet separately.

Sending USDC

The provider’s MATIC label identifies Polygon PoS for this entry. The network’s gas asset is POL; do not select Ethereum or Polygon zkEVM instead. Confirm the destination supports the exact USDC version returned by the provider. In particular, do not assume USDC, USDC.e and Binance-Peg representations are interchangeable.

For a standard self-custody transfer on Polygon PoS, allow for network fees in POL, separately from your USDC balance. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

Receiving USDT

Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Match the USDT network and token supported by the receiving service. A USDT balance on one chain does not automatically appear on another, and a dollar reference does not guarantee the quoted exchange value. This listed USDT/Optimism option has no separate memo field. If your destination requires additional instructions that this form cannot supply, choose another compatible destination before creating an order.

Refund address for this pair

Enter a refund address that accepts USDC on MATIC. The refund is sent in USDC on MATIC; verify that your refund wallet supports this exact asset and network.

SENDING ASSET

USDC is Circle’s dollar-referenced stablecoin. Native USDC and bridged representations can coexist, so a familiar ticker alone is not enough to identify a deposit asset.

RECEIVING ASSET

Tether USDt on OP Mainnet

USDt is Tether’s dollar-referenced token. The USDT ticker appears on several networks, each with its own token representation and transfer requirements.

Does a confirmed USDC deposit mean my USDT has arrived?
