Bridge to Arc: Move Assets to Circle's Arc Chain

What does "bridging to Arc" actually mean?

Bridging to Arc means moving value you hold on one blockchain — Ethereum, Base, Solana, Arbitrum, BNB Chain, anywhere — onto Arc, Circle's Layer-1 blockchain built for stablecoin finance. Nothing physically "moves." Depending on the route, your asset is either locked or burned on the source chain and an equivalent amount is released or minted on Arc.

Arc changes one thing about bridging that trips up people arriving from other chains: USDC is the native gas token. On Ethereum you bridge ETH first so you can pay gas, then bridge what you actually want. On Arc, the dollar you bridge is the gas. If USDC is what you send, you arrive fully funded. If you send ETH, SOL or another token, a good bridge route delivers it swapped into USDC on Arc so you can move immediately — which is exactly what the widget on this page does.

Two things this page is not about, because Google conflates them: Arc the blockchain is unrelated to the Arc web browser, and "bridging" has nothing to do with the ARC token or any airdrop. There is no official ARC token trading today; anything called "ARC" you are offered on another chain is not Circle's (details).

Which bridge to Arc should you use?

There are three real routes onto Arc, and which one is right depends on what you hold.

The rule of thumb: USDC in, use CCTP or the widget's native-USDC route; anything else in, use the widget. CCTP is Circle's own burn-and-mint protocol, so it produces the canonical USDC with no wrapped-token risk — the full mechanics are in How to Bridge USDC to Arc with CCTP. deBridge is an intent-based bridge: a network of solvers fills your order on Arc from their own liquidity, which is why it can accept any token and settle in seconds. A fair, bridge-by-bridge comparison, including Across, Stargate and Relay as they add Arc, lives at Arc Bridges Compared.

How to bridge to Arc in five steps

This is the flow using the widget at the top of the page. It works from a desktop browser with MetaMask, Rabby, Ledger (via MetaMask), Phantom (from Solana) or any WalletConnect wallet.

Step 1 — Add Arc to your wallet. MetaMask will prompt you to add the network the first time you bridge, but doing it in advance avoids a mid-flow surprise. Testnet: chain ID 5042002, RPC https://rpc.testnet.arc.io, currency symbol USDC, explorer https://testnet.arcscan.app. Mainnet parameters publish September 16 and appear on Add Arc to MetaMask the moment they are official — take them only from that page, arc.io or circle.com.

Step 2 — Connect your wallet in the widget and pick your source. Choose the chain your funds sit on and the token you are sending. The widget shows your balance on that chain.

Step 3 — Set the destination to Arc and the receive token to USDC. Arc is pre-selected as the destination on this page. Receiving USDC is the right default for almost everyone, because it is the gas token; you can swap into anything else on Arc afterwards on Uniswap or Aerodrome.

Step 4 — Review the quote. The widget shows the exact amount you will receive on Arc, the fee, and the estimated time before you sign. If the receive amount looks wrong, stop — it is far cheaper to re-quote than to reverse. Confirm the receiving address is your own wallet (it defaults to the connected one).

Step 5 — Approve (if needed) and confirm. Sending an ERC-20 like USDC or wBTC requires a one-time token approval on the source chain, then the bridge transaction itself. Native ETH or SOL skip the approval. Sign, wait for the order to fill, and your USDC appears on Arc. Verify on the Arc explorer; the balance in MetaMask may be labelled "ETH" by some wallet versions — the asset is USDC, the label is cosmetic (why).

Do you need gas on Arc before you bridge?

No — and this is the single biggest difference from bridging to an L2. Because gas on Arc is paid in USDC, the USDC you receive is spendable immediately. There is no faucet step, no "bridge a little ETH first," no stranded balance you cannot move. A typical Arc transaction costs a fraction of a cent, so even a $5 bridge leaves you able to make hundreds of transactions (how Arc fees work).

The one caveat: if you bridge a non-USDC token and choose to receive that token rather than USDC, you will arrive with zero gas. Receive at least a few dollars of USDC on the first bridge.

How long does bridging to Arc take?

Native USDC via CCTP takes roughly 60 seconds inbound, bounded by how long the source chain takes to finalize the burn — Ethereum is the slow end, Base and Solana are faster. Bridging out of Arc is quicker still because Arc's deterministic sub-second finality lets the attestation issue almost immediately. Intent-based routes through the widget typically settle in seconds to a few minutes, because a solver front-runs the slow part with its own liquidity and gets reimbursed later. Exchange withdrawals depend on the exchange's own processing queue.

What does it cost to bridge to Arc?

Three components: gas on the chain you are leaving (the dominant cost from Ethereum, negligible from Base or Solana), the bridge's own fee (CCTP's fee is small and flat-ish; deBridge quotes a per-route fee inline), and the swap spread if you are converting a non-USDC asset to USDC en route. Gas on the Arc side is effectively zero. The widget shows the all-in receive amount before you sign, which is the number to compare.

Safety checks before every bridge

Launch week is peak season for fake bridges. Bookmark this page and check four things every time. The URL bar must read trustswap.com/arc/bridge or app.debridge.com — nothing else. The destination network in your wallet must be Arc with chain ID 5042 (0x13b2), not a look-alike. The receiving address must be your own wallet, not an address a Telegram "support agent" gave you. And the quote must arrive from the widget, never from a DM. Revoke any leftover token approvals afterward if you bridged a large amount (how). If a transaction has gone wrong — sent to the wrong chain or the wrong address — Wrong Address or Network: Recovery Guide walks through what can and cannot be recovered.

What can you do once your USDC is on Arc?

Most people bridging this week are here to be early. The uncontested moves are launching a token on Arc — minting costs cents in USDC and takes under five minutes — locking liquidity on a Uniswap or Aerodrome pool so buyers trust you (guide), setting up team vesting (guide), or simply parking dollars where Aave and Morpho are live from day one (lending on Arc). Track everything you bridged and bought in The Crypto App, which supports Arc from launch.

Bridge to Arc from specific chains

Bridge from Ethereum to Arc. USDC: CCTP or the widget, expect Ethereum gas plus ~1 minute. ETH: the widget, received as USDC. This is the most expensive origin purely because of Ethereum gas; consider moving to Base first if you bridge often.

Bridge from Base to Arc. The cheapest EVM origin. Coinbase users can withdraw USDC to Base for free, then bridge to Arc for cents.

Bridge from Solana to Arc. Connect Phantom or Solflare in the widget; USDC on Solana routes natively via CCTP, SOL routes via the widget and arrives as USDC. Arc's address format is EVM (0x…), so you need an EVM wallet to receive.

Bridge from Arbitrum, Optimism, Polygon, Avalanche, BNB Chain to Arc. All supported as widget origins; USDC on CCTP-enabled chains routes natively.

Bridge from an exchange to Arc. Check whether your exchange's withdrawal screen lists "Arc" as a network. If it does, withdraw USDC directly — no bridge needed. If it does not yet, withdraw to Base and bridge from there. Per-exchange walkthroughs: Coinbase to Arc, Binance to Arc, Kraken to Arc.

Bridging out of Arc

The widget works in both directions — set Arc as the source. Outbound CCTP transfers benefit from Arc's instant finality, so leaving is usually faster than arriving. Keep a few cents of USDC on Arc after you leave so you can come back without a cold-start.

Frequently asked questions

How do I bridge to Arc? Use the bridge widget on this page: connect your wallet, pick the source chain and token, select Arc as the destination, review the quote and confirm. USDC arrives on Arc in about a minute and is immediately usable because USDC is Arc's gas token.

What is the best bridge to Arc? For USDC, Circle's CCTP is canonical — it burns on the source chain and mints native USDC on Arc with no wrapped-token risk. For any other asset, or for one-click any-chain-to-Arc, deBridge (the widget here) is the fastest general route. The full comparison is at Arc Bridges Compared.

Can I bridge ETH to Arc? Yes. Send ETH through the widget and receive USDC on Arc. ETH is not native to Arc, so receiving USDC — the gas token — is the practical choice; you can swap into a bridged ETH representation on an Arc DEX afterward if you need it.

Do I need ETH for gas on Arc? No. Gas on Arc is paid in USDC. Bridging USDC means you land with gas already in hand.

Is bridging to Arc safe? The protocols are audited and CCTP is operated by Circle itself. The realistic risks are user-side: fake bridge sites, fake network parameters, and phishing "support." Bridge only from this page or app.debridge.com, verify the Arc chain ID against arc.io, and never share a seed phrase.

What is Arc's chain ID? Testnet is 5042002. Mainnet chain ID publishes on September 16, 2026 and is mirrored on Add Arc to MetaMask as soon as Circle publishes it.

Does deBridge support Arc? Yes — deBridge supports Arc (chain ID 5042), and the widget on this page defaults to ETH on Ethereum → USDC on Arc. Any token from any major chain can be routed to Arc with USDC on arrival; if a specific token has no route, use the CCTP route in How to Bridge USDC to Arc instead.

Can I bridge from Solana to Arc? Yes — USDC on Solana routes natively through CCTP, and SOL routes through the widget and arrives as USDC. You need an EVM (0x) wallet address on the Arc side.

Why does my Arc balance show "ETH"? Some wallet builds label every native balance "ETH." On Arc the native asset is USDC with 18 decimals; the label is cosmetic. Arcscan shows it correctly.

How much does it cost to bridge to Arc? Source-chain gas plus the bridge fee, both shown in the widget quote. From Base or Solana the total is typically well under a dollar; from Ethereum mainnet, Ethereum gas dominates. Gas on Arc itself is fractions of a cent. Disclosure: routes through the widget on this page include a 0.6% TrustSwap affiliate fee, which is part of the quote you see before signing.

Can I bridge USDT or other stablecoins to Arc? Through the widget, yes — they arrive as USDC. Arc is USDC-native; other stablecoins are not gas and may have thin liquidity early.

Can I bridge back out of Arc? Yes. Set Arc as the source in the widget or use CCTP outbound; Arc's fast finality makes exits quick.
