Optimism → MATIC

Swap ETH to USDT

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

Ethereum (Optimism) to Tether (Polygon)

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

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

Address and network checks

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

Sending ETH

Select OP Mainnet, often labeled Optimism. Its ETH balance and token balances are separate from those on Ethereum mainnet. Native ETH and wrapped Ether (WETH) are different assets. Use the ETH balance on the selected network; do not substitute WETH for an ETH deposit.

For a standard self-custody transfer on OP Mainnet, allow for network fees in ETH in addition to the amount you send. 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.

How much USDT will I get for ETH?

Enter your ETH amount to see an approximate receive amount. Click Find the best route to compare providers. Floating rates can change before conversion; fixed quotes follow the selected provider’s terms.

Does a confirmed ETH deposit mean my USDT has arrived?

No. Deposit confirmation on OP Mainnet, provider processing and payout on Polygon PoS are separate steps. Use Track swap to see the order status, then check the USDT balance on the receiving network. A live quote or historical route check does not guarantee completion time.
