Arc is the Layer-1 blockchain from Circle, the company behind USDC. It runs on stablecoin gas, settles in under a second, and went from most-watched testnet to live mainnet on September 16. Real funds now move on the chain, and the practical question stayed the same: how do you actually get money onto Arc?
This guide covers the two bridges that work properly today, the wallet setup, and a shortcut for traders who want Arc coins without bridging anything at all.

Update September 16: fully rewritten for the Arc mainnet launch. The old testnet steps are gone. Everything below applies to real USDC.
Arc Bridging Basics: What Makes This Chain Different
Before touching a bridge, you need to understand the one design choice that separates Arc from almost every other chain: USDC is the gas token.
On Ethereum you pay fees in ETH, and on Solana you pay in SOL. Arc charges every transaction fee directly in USDC. There is no volatile gas token to buy first, and fees stay predictable in dollar terms. Anyone who has ever been stranded on a chain with funds but no gas will appreciate how much friction this removes.
The second thing to know is how assets move. Bridging runs on Circle’s Cross-Chain Transfer Protocol (CCTP). Instead of locking your USDC in a contract and handing you a wrapped IOU, CCTP burns it on the source chain and mints native USDC on Arc. You end up with the real asset, not a derivative that depends on some bridge staying solvent. After years of wrapped-token exploits, burn-and-mint is a genuine security upgrade.
Mainnet went live on September 16, 2026, with over 100 ecosystem partners active from day one. Founding validators include BlackRock, Visa, Mastercard, and Standard Chartered, which tells you how seriously institutions take this chain.
What You Need Before Bridging to Arc
Gather these four things first, and the actual bridge takes five minutes.
1. A supported Arc wallet. Arc is fully EVM-compatible, and the big three all run it natively already: MetaMask, Phantom, and Rabby. Each review covers how we set them up for farming. Hardware wallets like Ledger work too.
2. The Arc network added to your wallet. Most bridge interfaces prompt you to add it automatically on arrival. Accept the prompt once and you are done forever.
3. Funds on a source chain. USDC is the cleanest asset to bridge. Other tokens work through the second route below, which swaps on the way over.
4. Gas on the source side. The source chain still charges its own native token to approve and send the transaction, so keep a little ETH or SOL there. Once funds land on Arc, every fee comes straight out of your USDC balance.
How to Bridge to Arc Mainnet: Two Routes That Work
Launch day brought a flood of third-party routes, and some quoted genuinely painful rates in the first hours. We tested the field so you don’t have to. Two options stand out.
Route 1: Circle’s USDC Bridge (Official)
The official route is Circle’s USDC Bridge, run by the company that issues the stablecoin itself. It’s pure CCTP: native USDC leaves the source chain, native USDC arrives on Arc, and nothing wrapped ever touches your wallet. We recommend it for larger amounts.
- Connect your wallet at the bridge interface.
- Select your source chain and enter the USDC amount.
- Set Arc as the destination.
- Approve and confirm. Your wallet asks for a spend approval first, then the transfer. Both need source-chain gas.
- Wait for the mint. Transfers typically complete within minutes.
Route 2: Relay (Fast and Flexible)
For speed and flexibility, use Relay. It covers far more source chains and tokens, so you can hop over from Solana or any major L2 without swapping to USDC first. Transfers usually land in under a minute, and fees stay friendly on smaller sizes. The flow mirrors the steps above: connect, pick source and token, set Arc as destination, confirm.
Verifying Your Bridge
Once the transaction completes, open the Arc explorer and paste your wallet address. The minted USDC balance and incoming transaction should appear within minutes, and your wallet displays the balance as soon as the Arc network is added. That explorer entry doubles as proof of early activity.
Skip the Bridge: Trade Arc Coins on fomo
Only here for the new Arc memecoins? Then you don’t need a bridge at all. The fomo app supported Arc on day one, and its unified balance lets you buy Arc coins directly with funds sitting on any other chain. No network switching, no gas juggling, one tap. Read our full FOMO app review if you’re new to the app, and grab code FairSaltySquid for 10% off fees.
Bridging to Arc and the Airdrop Angle
Let’s be direct about why many readers are here. Circle has confirmed it is exploring an ARC token, and no launch came with mainnet. That leaves the door wide open for a retroactive reward, and bridging real funds is among the most fundamental on-chain actions a wallet can record.
Testnet farmers spent almost a year building history before launch. If you missed that window, early mainnet activity is the next best position: bridge in, transact, use apps, and spread the activity over weeks rather than spamming one afternoon. Our Arc Network testnet listing tracks the tasks and any eligibility updates.
A word of caution while the hype runs hot: fake bridge sites and fake ARC claim links are circulating on social media. Stick to the two routes above, and treat any “claim your ARC airdrop” link with maximum suspicion until Circle announces something itself.

Final Words
Bridging to Arc remains one of the simpler cross-chain experiences in crypto, because Circle controls the full stack: the stablecoin, the transfer protocol, and the chain. Pick the official USDC Bridge for size, Relay for speed and odd tokens, or skip the whole exercise and trade Arc coins on fomo directly.
The smart move now is early, genuine activity while the chain is days old. Launchpads are already racing for the top spot on Arc, and our breakdown of the biggest Robinhood launchpads shows how these races usually play out. See you in the trenches!
FAQ
Is Arc mainnet live yet? Yes. Arc mainnet launched on September 16, 2026, with bridges, wallets, and trading apps active from day one.
Is there an Arc airdrop? Nothing official yet. Circle has said it is exploring an ARC token, and no token launched with mainnet, so early users are positioning for a potential retroactive reward.
What is the gas token on Arc? USDC. Arc charges fees in stablecoins instead of a volatile native token, which keeps costs predictable in dollar terms.
Do I need ETH to bridge to Arc? Only on the source side. Sending the bridge transaction requires the source chain’s native token. On Arc, everything runs on USDC.
Which wallets work with Arc? MetaMask, Phantom, and Rabby all support Arc mainnet natively, and most other standard EVM wallets work as well.
What is CCTP? The Cross-Chain Transfer Protocol is Circle’s system for moving USDC between chains. It burns USDC on the source chain and mints native USDC on the destination, avoiding wrapped tokens entirely.
Can I trade Arc coins without bridging? Yes. Cross-chain trading apps like fomo let you buy Arc tokens from a unified balance, with no bridge or gas setup required.
