TON → Mainnet

Swap USDT to OP

Exchange USDT from TON 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 (Toncoin) to Optimism (Mainnet)

You send: Tether (Toncoin)USDT · TON
You receive: Optimism (Mainnet)OP · Mainnet

Enter your amount to check live availability for USDT on TON → OP on Mainnet. A provider quote is required before you can create a swap.

Address and network checks

Use the order’s TON deposit address for USDT, and your own OP Mainnet receiving address for OP. Keep the refund address on TON; the payout address is not automatically a valid refund destination.

Sending USDT

Use the token on TON and copy any required comment or memo from the receiving service. The USDT token amount and TON needed for fees are separate balances. 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. Copy any memo or extra ID included with the provider’s deposit address.

For a standard self-custody transfer on TON, allow for network fees in TON, 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

Enter a refund address that accepts USDT on TON. This listed asset has an extra-ID field; include the refund memo or extra ID, or explicitly enter 0 when your wallet requires none.

Does a confirmed USDT deposit mean my OP has arrived?
