Swap USDC from Arbitrum One to DAI on Ethereum

Swap USDC from Arbitrum One to DAI on Ethereum. Native Circle USDC leaves Arbitrum One. Maker DAI is what can arrive on Ethereum. You switch from Circle to Maker, and you land on mainnet where gas is ETH.

The debit is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, not USDC.e. The credit is 0x6B175474E89094C44Da98b954EedeAC495271d0F. Arbiscan records the USDC on chain id 42161. Etherscan records Maker's DAI on chain id 1. Not Nova. DAI can trade away from one dollar. Ethereum is where that DAI contract lives.

Maker, not Circle and not Tether

If you needed Ethereum USDC, the contract is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48. If you needed Tether, it is 0xdAC17F958D2ee523a2206206994597C13D831ec7. DAI is neither. This route is wrong for those tickers.

Bridged USDC on Arbitrum will not sell

0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8 is the older bridged dollar on Arbitrum. This page wants native USDC. Approving USDC.e spends a token the quote did not name. Check Arbiscan.

DAI cannot pay mainnet

After the credit you still need ETH on chain id 1. DAI is not gas, and ETH is not WETH. About 12 second blocks are Ethereum, not the bridge. This quote does not buy the native ETH label.

ETH on Arbitrum is a separate fee

Chain id 42161 charges its own ETH. The ARB token will not pay it. Nova is the wrong network. Leave ETH on Arbitrum One so the send can land.

Is DAI issued by Circle?

No. USDC is Circle. DAI is Maker's token at 0x6B175474E89094C44Da98b954EedeAC495271d0F on Ethereum.

If your form says Circle or Tether, switch routes. Maker is not a stand-in for Circle or Tether on a deposit form.

Do I need ETH on both chains?

You need ETH on Arbitrum One, chain id 42161, to send, and ETH on Ethereum, chain id 1, if you want to move the DAI afterward. DAI will not pay mainnet. The route does not include that mainnet ETH. About 12 second blocks are not the bridge clock. Arbiscan and Etherscan do not share a balance.

What if the wallet is on Nova or holds USDC.e?

Then stop. Nova is not Arbitrum One. USDC.e is 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8, not 0xaf88d065e77c8cC2239327C5EDb3A432268e5831. Arbiscan shows the contract you approved. The DAI credit, if you use the right token, appears only on Etherscan. You must start on Arbitrum One with native USDC, or this DAI credit will not be the one you expect.
