Phantom lists Arc as a supported network. MetaMask also lists Arc and Arc’s own documentation provides a MetaMask setup path. Both are candidates for a dedicated Arc funding wallet; connection to a particular bot remains a separate question.
Arc uses USDC for network fees. An Ethereum-style address does not mean Ethereum ETH will pay Arc fees. Confirm that the balance and receiving screen refer to Arc Mainnet.
Current support comparison
| Wallet | Network access | Application connection | Setup |
|---|---|---|---|
| Phantom | Active network support | Supported network; application connector required | Enable the network in Active Networks |
| MetaMask | Supported network | Compatible application connector required | Check the network list before manual setup |
Network support does not establish every swap route, token listing, bot integration or hardware-wallet combination.
MetaMask for Arc or Phantom: what changes in practice?
MetaMask for Arc offers a listed-network path and an official Arc manual fallback. Phantom exposes Arc through Active Networks. Prefer the listed configuration when available; a custom-network form is not required simply because Arc is newer than Ethereum. Check the application’s Arc connector before treating either wallet as a direct trading interface.
For asset visibility, separate the Arc fee balance from a token with a similar label on another network. Arc’s documentation notes that some wallet displays can label its USDC gas balance as ETH. Confirm the chain ID, explorer record and fee quote together rather than buying Ethereum ETH to correct a display label.
Use the mobile or extension surface that the Arc application documents. An EVM hardware-wallet integration is not evidence that its device screen correctly presents Arc’s custom gas asset. Verify that combination with the wallet and device documentation; if it is unconfirmed, keep hardware support marked unknown. A bot deposit address is a funding flow, not proof of an Arc wallet connector.
Add Arc to MetaMask without confusing testnet
Check MetaMask’s network list first. If manual configuration is needed, verify each value against Arc’s current official network reference. Mainnet: Arc; RPC https://rpc.mainnet.arc.io; chain ID 5042; currency USDC; explorer https://explorer.arc.io.
Arc Testnet uses chain ID 5042002 and a different RPC. Faucet assets are test assets. If an older tutorial tells you to add 5042002, it is not configuring mainnet. Arc notes that some wallet interfaces can display the gas balance as ETH even though the underlying fee asset is USDC. Do not fund based on a ticker alone.
Use Phantom as an Arc funding wallet
Update Phantom, enable Arc in Active Networks and use Receive to select Arc. Confirm Arc on the sending service as well. Check the destination balance before making another transfer; sending assets to the same address on Ethereum does not move them to Arc.
Select an Arc application’s supported wallet connector and review its transaction request. Native wallet support is not a claim that every Arc application has implemented a Phantom connection.
Fund the trading balance deliberately
Use a route documented for the source asset and Arc destination. Review bridge availability, received asset and fees before signing. Keep a USDC reserve for Arc transactions rather than putting the full balance into a position.
Start with the Arc trading procedure and the current Arc bot directory. A tool’s Arc trading availability does not establish its bridge availability or key-export model.
Can I import an existing bot wallet?
Only if the bot provides an exportable self-custodial key and the wallet supports that key format. A wallet app’s import feature does not prove that a bot lets you export a key. If custody or export is unverified, use dedicated-wallet funding guidance and check the provider’s official documentation.
A compatible import opens the same on-chain address in another app. It is not a transfer to a fresh wallet and does not take signing access away from the original bot. Prefer a fresh account if you want to isolate a new trading balance. For hardware-backed accounts, use the documented hardware connection; never type the device’s recovery phrase into a software wallet.

Frequently asked questions
Do I need ETH to use MetaMask on Arc?
Arc uses USDC for gas. Some interfaces may show an ETH label for the underlying Arc gas balance, so verify the network and current Arc documentation before funding.
How do I distinguish Arc Mainnet from Arc Testnet?
Verify the network parameters against Arc’s official reference. Mainnet uses chain ID 5042; testnet uses 5042002. Test assets cannot fund mainnet activity.
Can a wallet recover funds held by a bot?
A wallet app cannot recover a custodial account. Import is conditional on a legitimate exportable key and compatible format; it does not guarantee recovery.
