Optimism → Mainnet

Swap USDT to ARB

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

Tether (Optimism) to Arbitrum (Mainnet)

You send: Tether (Optimism)USDT · Optimism
You receive: Arbitrum (Mainnet)ARB · Mainnet

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

Address and network checks

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

Sending 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.

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

Receiving ARB

Choose Arbitrum One using the Mainnet option shown in this directory. Follow the selected provider’s exact deposit instructions before sending. Select the Arbitrum network for this listed ARB asset and retain ETH on that network for an ordinary wallet transfer. Holding ARB does not by itself pay the ETH gas fee. This listed ARB/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 Optimism. The refund is sent in USDT on Optimism; verify that your refund wallet supports this exact asset and network.

Does a confirmed USDT deposit mean my ARB has arrived?
