MATIC → Mainnet

Swap USDT to OP

Exchange USDT from Polygon PoS into OP on OP Mainnet. The provider waits for the USDT deposit before arranging the OP payout on the destination network. Track those as separate transactions rather than using a sending-chain confirmation as proof of receipt.

Tether (Polygon) to Optimism (Mainnet)

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

Enter your amount to check live availability for USDT on MATIC → OP on Mainnet. 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 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.

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

Receiving OP

Choose OP Mainnet using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Send the OP token on the network specified by the order. If sending from a normal self-custody wallet on OP Mainnet, allow for gas paid in ETH, not OP. This listed OP/Mainnet 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

Does a confirmed USDT deposit mean my OP has arrived?
