Swap USDC from Arbitrum One to USDT on Ethereum
Swap USDC from Arbitrum One to USDT on Ethereum. Native Circle USDC leaves Arbitrum One. Tether USDT is what can arrive on Ethereum. You change issuer on the way from a layer 2 to mainnet, and USDC.e is the wrong token to start from.
Sell 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on chain id 42161, not Nova and not USDC.e at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8. Buy 0xdAC17F958D2ee523a2206206994597C13D831ec7 on chain id 1. Arbiscan shows the debit. Etherscan shows Tether. ETH pays gas on both chains, and the balances are separate. Arbitrum One is not Ethereum, even though both use ETH.
USDC.e is the wrong start
Keeping Circle means a different mainnet contract
ETH on both sides, still two balances
Not a same-asset canonical bridge

Frequently asked questions
What is the best way to swap USDC from Arbitrum One to USDT on Ethereum?
Sell 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on chain id 42161, not Nova and not USDC. e at 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8.
Is Arbitrum USDC.e valid here?
No. USDC.e is 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8. This route spends native USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 on Arbitrum One, chain id 42161, not Nova. The credit is Tether at 0xdAC17F958D2ee523a2206206994597C13D831ec7. Arbiscan and Etherscan are separate. The ticker USDC is not enough. Nova is the wrong network, and USDC.e is the wrong token.
Will the USDT pay Ethereum gas?
No. 0xdAC17F958D2ee523a2206206994597C13D831ec7 is not ETH. Chain id 1 charges ETH, and blocks there are about 12 seconds. That block time is not a finish time for the bridge. Keep ETH on Ethereum or the new USDT cannot move. ETH on Arbitrum does not cover mainnet.
What if I wanted Circle USDC on Ethereum?
Then this route is wrong. Ethereum USDC is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. This output is Tether. Circle and Tether are different issuers. Switch before you approve the Arbitrum USDC. Etherscan should show the contract you chose. Circle USDC on Ethereum is a different contract. Do not deposit Tether where Circle was requested.
