Using Arc on Mobile: Wallets, Apps & Limits

Arc is an EVM chain, so any mobile wallet that lets you add a custom network can use it today — MetaMask, Rabby, Trust Wallet, Coinbase Wallet (Base app) and Rainbow all qualify, and some may list Arc natively. Sending USDC from your phone is exactly what Arc's cents-and-sub-second design is good at; managing a treasury or signing complex contracts from your phone is not. This page covers the setup, the app-connection flow, and where to stop.

Which mobile wallets work with Arc?

Any that support custom EVM networks, which is most of them. MetaMask Mobile is the default (Circle named MetaMask in Arc's day-one cohort; whether Arc ships in its built-in network list or needs a manual add, confirm in your app). Rabby Mobile supports custom networks and, since mid-2026, custom-network token display. Trust Wallet has a custom-network flow. Coinbase Wallet — rebranded as the Base app in 2025 — supports custom networks in settings, and Arc's official docs offer a one-click add for it, along with Rainbow. Binance Wallet is named in Arc's cohort as well (the exchange-vs-wallet distinction). The cross-cutting rule: take network parameters only from the mainnet-live page or docs.arc.io. Fake "add Arc" links with malicious RPCs are a live attack (current scams), and a wrong RPC on your phone shows you balances that aren't real.

How do you add Arc on your phone?

MetaMask Mobile: open the network selector → Custom → Add a custom network → enter Arc's name, RPC URL, chain ID, currency symbol (USDC) and explorer → save → switch to it. Trust Wallet: manage assets → add → Network → same fields → save. Coinbase Wallet/Base app: Settings → Active network → add → same fields. Two notes that catch people. Custom networks don't sync between your phone and your browser extension — add Arc on each device separately. And some wallets label the native balance "ETH" for any EVM chain; on Arc the native token is USDC, the number is right and the ticker is cosmetic (why). If Arc appears natively in your wallet's list, prefer that over a manual entry — fewer typos, correct labels.

How do you connect to Arc apps from mobile?

Two ways. In-wallet browsers: MetaMask, Trust Wallet and others include a dapp browser — open the app's URL inside the wallet and it connects directly, with the wallet already on Arc. WalletConnect: on any browser, tap "Connect wallet," choose WalletConnect, and approve the session in your wallet app via QR code or deep link; the app may then ask your wallet to switch to or add Arc, which you approve in the wallet. Both paths work with Uniswap, Aerodrome, Aave and Team Finance on Arc. The habit that keeps you safe on a small screen: type or bookmark the app URL yourself — never follow a link from a message — and read every approval prompt before confirming; the phone's convenience is the attacker's convenience too (how drainers work).

What is mobile actually good for on Arc?

Payments and everyday use. Sending USDC to a friend or a merchant costs fractions of a cent and settles in under a second — the phone is the natural device for it (how sending works). Checking balances, claiming vested tokens through a project's claim portal, and small swaps are all comfortable. Receiving is trivial: your Arc address is the same as your address on every other EVM chain, so a QR code works.

What are the limits?

Three worth respecting. Security ceiling: a phone wallet is a hot wallet on a device that also runs your messaging apps and browser; keep on it what you'd keep in a physical wallet, and hold the rest behind hardware (Ledger on Arc). Some hardware wallets pair with mobile via Bluetooth, which closes part of this gap. Complex signing: reading a multi-step contract interaction on a phone screen is where mistakes happen — approve unlimited allowances, sign a permit you didn't understand — so do treasury operations, lock management and multisig approvals from a desktop with a hardware device (multisig setup). Recovery: a seed phrase created on a phone is only as safe as its backup — write it down, never screenshot it (self-custody basics). Mobile is where you spend on Arc; it shouldn't be where you store.

FAQ

Which mobile wallet is best for Arc? MetaMask Mobile is the default — most apps are tested against it and it's in Arc's day-one cohort. Rabby, Trust Wallet, Coinbase Wallet (Base app) and Rainbow also work via custom networks.

Does MetaMask Mobile have Arc built in? Check your app's network list — Circle named MetaMask a day-one partner. If Arc isn't listed, add it manually with parameters from docs.arc.io only.

Why doesn't Arc show on my phone after I added it on desktop? Custom networks don't sync across devices. Add it on each one.

Can I use a hardware wallet with a mobile Arc wallet? Some hardware wallets pair with mobile apps over Bluetooth; check your device's compatibility. For anything substantial, desktop plus hardware remains the safer setup.

Is it safe to hold USDC on my phone? For spending amounts, yes, with a locked phone and a properly backed-up seed. For savings or project funds, no — use hardware or a multisig.
