Swap USDC to USDT

Exchange USDC on Base for USDT on Polygon PoS. 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 (Base) to Tether (Polygon)

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

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

Address and network checks

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

Sending USDC

Switch the wallet to Base. ETH on Ethereum mainnet cannot pay the normal gas fee for a separate token transfer on Base. 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 Base, allow for network fees in ETH, separately from your USDC balance. Wallet sponsorship and exchange withdrawal charges can differ; check the sending wallet’s final fee.

Receiving USDT

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. 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/MATIC 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.

RECEIVING ASSET

Tether USDt on Polygon PoS

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?
