Swap USDT from Arbitrum One to USDC on BNB Chain

Swap USDT from Arbitrum One to USDC on BNB Chain. Tether USDT leaves Arbitrum One and BSC USDC arrives on BNB Chain.

Sell Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One, six decimals. Arbiscan, chain id 42161, not Nova. Gas is ETH. The receive contract is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d on BNB Chain. BscScan lists that token as Binance-Peg USDC, eighteen decimals. It is not Circle's native USDC on Ethereum or Arbitrum, and Circle's published native list does not treat this as the same contract. Chain id 56, gas in BNB, blocks about 3 seconds. That block time is not a credit promise.

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

Binance-Peg USDC is not Circle native

Circle's USDC on Arbitrum One is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. You are not selling that here, and you are not receiving it. You sell Tether and you can receive 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d. If a desk redeems only through Circle's native contracts, this BSC balance may not be on that list. Read BscScan and the issuer notes before you tell anyone you hold Circle USDC.

Six decimals sold, eighteen bought

Arbitrum USDT uses six decimals. The pegged USDC on chain id 56 uses eighteen. A raw unit comparison will look like a huge surplus or a huge loss. Use the token amounts on the quote. Also remember both tickers say a dollar and the issuers differ, so the minimum can slip off one-for-one. If that slip is too wide, do not sign. Request a new quote rather than arguing with an expired minimum.

BNB is still required after a stablecoin arrives

Pegged USDC does not pay gas on BNB Chain. Native BNB does, and the sentinel would have been the way to ask for it. This output is a BEP-20. Keep ETH on Arbitrum One for the Tether approval. BNB Chain will hold the pegged dollars only if chain id 56 is the network you gave as the destination.

Wrong for Tether fans and for Circle native fans

This page is wrong if you wanted BSC USDT at 0x55d398326f99059fF775485246999027B3197955, because the ticker changes to USDC. It is wrong if you wanted Ethereum Circle USDC at 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. It is wrong if your balance is not 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, and wrong on Nova.

Frequently asked questions

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

Sell Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One, six decimals. Arbiscan, chain id 42161, not Nova.

Is the USDC on BNB Chain issued as Circle native USDC?

The contract this route names is 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Binance-Peg USDC, eighteen decimals. That is not Circle's Arbitrum USDC and not Circle's Ethereum USDC. Confirm the page on BscScan. You spend Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One. If you need Circle's native contract, this receive address is the wrong one.

Why is one dollar such a different integer?

Six decimals on Arbitrum USDT, eighteen on the BSC USDC contract. The quote should display whole tokens. Do not subtract the raw base units and call the gap a fee. There can still be a real price gap because the issuers differ. Read the minimum.

Does this route pay the BNB Chain fee for me?

No. Gas on chain id 56 is native BNB, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, and this output is a BEP-20. You need ETH on Arbitrum One to start. You need BNB afterward if you will move the pegged USDC. Arbiscan is only for the Tether spend on chain id 42161.
