Swap USDT from BNB Chain to USDC on Arbitrum One

Swap USDT from BNB Chain to USDC on Arbitrum One. You send Binance-Peg USDT on BNB Chain and you receive Circle's native USDC on Arbitrum One.

Approve 0x55d398326f99059fF775485246999027B3197955, the 18-decimal Tether peg. BscScan shows it on chain id 56. Gas is BNB. Blocks are about 3 seconds. Native USDC on Arbitrum One is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Match the full string on Arbiscan. Chain id 42161, not Nova. It is not the older bridged USDC.e. Gas after arrival is ETH. USDC will not pay it.

Diagram for Swap USDT from BNB Chain to USDC on Arbitrum One
USDT leaves BNB Chain. USDC is what can arrive on Arbitrum One.

Tether's peg is the only thing approved

0x55d398326f99059fF775485246999027B3197955 is the input. The USDC peg and native BNB are different routes. You also change issuer, from Tether to Circle. If you needed Tether to stay Tether on Arbitrum One, this page is the wrong tool. Keep BNB for the fee. Do not compare raw integers across 18 and 6 decimals.

Native USDC, checked on Arbiscan

0xaf88d065e77c8cC2239327C5EDb3A432268e5831 is Circle's native USDC on Arbitrum One. Bridged USDC.e is a different contract with the same ticker. Nova will not show this One balance. ETH has to sit in the wallet or the USDC cannot move. The ARB token does not cover that fee.

ETH, WETH, and ARB are other endings

Each has a page from this same peg. This page is only native USDC. A local swap on BNB Chain is enough when Arbitrum was not required. Arbitrum on this route means One, chain id 42161. The quote does not lock the Circle dollars, and it does not name a finish time.

Issuer change, then an ETH problem

BscScan proves the peg left. Arbiscan proves which USDC arrived. BNB pays the first side. ETH pays the second. Read the minimum USDC before you sign. A 3 second block is not the whole route. If the floor is short, do not sign. ETH on Arbitrum One is still required after that.

Frequently asked questions

What is the best way to swap USDT from BNB Chain to USDC on Arbitrum One?

Approve 0x55d398326f99059fF775485246999027B3197955, the 18-decimal Tether peg. BscScan shows it on chain id 56.

How do I avoid the bridged USDC on Arbitrum One?

Match 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbiscan, chain id 42161. That is Circle's native USDC. A bridged USDC.e copy can share the ticker and still be the wrong token. The input was 0x55d398326f99059fF775485246999027B3197955 on BscScan. You need ETH afterward. Nova is not the chain, and ARB is not the gas.

Is this the USDT I already use on BNB Chain, just moved?

No. You sell the Tether peg and you receive Circle USDC. The issuers differ, and the chains differ. If a desk asked for Tether on Arbitrum One, this route is the wrong tool. BscScan and Arbiscan will not show one shared balance. Gas out is BNB. Gas on One is ETH.

Can I move the USDC with the ARB token I already hold?

No. ARB does not pay gas. ETH does, on chain id 42161. Native USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 cannot pay it either. Arbiscan can show the token while a transfer fails. BNB left on BNB Chain does not help. Add ETH first.
