Swap USDT from Ethereum to USDC on BNB Chain

Swap USDT from Ethereum to USDC on BNB Chain. Wallets that need Binance-Peg USDC spend Ethereum Tether and receive that dollar on chain 56.

You send Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7, the 6 decimal USDT on Etherscan. You receive 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, Binance-Peg USDC on BscScan, which uses 18 decimals. It is a pegged dollar on chain 56, and it is a different contract from Circle USDC on Ethereum. Gas for the send is ETH on chain id 1. Blocks there take about 12 seconds. BNB Chain, chain id 56, then charges BNB. Open BscScan on the pegged USDC and confirm the name before you send it to an app.

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

Two dollars, two issuers, two chains

Tether's Ethereum contract is what you spend. Circle is the name people associate with USDC, and on Ethereum that contract is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This route does not deliver that contract. It delivers Binance-Peg USDC. If a chain 56 app has whitelisted 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d, this is the matching output.

Decimals jump from 6 to 18

Ethereum USDT shows 6 decimals on Etherscan. The received pegged USDC shows 18 on BscScan. Import 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d with the explorer's decimals, or the wallet will invent a balance. The source approval is only for 0xdAC17F958D2ee523a2206206994597C13D831ec7.

Stay on Ethereum to flip USDT into Circle USDC

This route is the wrong tool when both legs should remain on mainnet. USDT and Circle USDC already have deep books there. Bridging is justified when the dollar you need is the BNB Chain peg. Ethereum is where the Tether starts, and where the ETH gas is paid.

BNB still has to be in the wallet

Pegged USDC does not pay gas on chain id 56. After it arrives you need BNB for the next move, and blocks on BNB Chain are about 3 seconds. If the wallet is empty of BNB, add gas before you try to spend the new dollars.

Frequently asked questions

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

Is Binance-Peg USDC the same token as Circle USDC on Ethereum?

They share a ticker and they are different contracts. Circle USDC on Ethereum is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This route pays 0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d on BscScan. Check the app you are funding. If it wants Ethereum USDC, this route delivers the wrong chain and the wrong address.

Which token do I approve on Ethereum?

Approve Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7 on Etherscan. USDT on Ethereum often needs a fresh approval because the contract does not support the newer approval pattern. Keep ETH in the same wallet for gas on chain id 1. The USDT itself cannot pay that fee.

What if the chain 56 app wants BSC-USD instead?

BSC-USD is Tether on BNB Chain, at 0x55d398326f99059fF775485246999027B3197955. This route pays Binance-Peg USDC. If the app's allowlist is the Tether contract, switch to a route that outputs that address. Sending the wrong stable into a pool will not credit you.
