Bridging Polygon to Arbitrum
Polygon keeps transactions cheap and its app ecosystem is broad, but the deeper DeFi pools and perps markets tend to concentrate on Arbitrum One. Bridging over usually lands you on an ETH-gas chain where trades confirm in under a second and liquidity for venues like GMX and the larger lending markets runs deeper. Fees on the Arbitrum side typically sit at a few cents rather than Polygon's fraction-of-a-cent gas, which is generally the trade-off for reaching that concentrated liquidity.
Polygon PoS is a comfortable place to hold and spend, with gas usually costing a fraction of a cent and blocks settling in roughly two seconds, but its DeFi depth is more modest than what sits on Arbitrum. Arbitrum One typically carries the deepest liquidity of any layer 2, home to venues like GMX and Uniswap and a large perpetuals scene, which is the main draw for people making this move. Traders and liquidity providers often want tighter pricing and larger pools than they can reliably find on Polygon, and Arbitrum's optimistic-rollup design gives them sub-second confirmations while still settling to Ethereum. The trade-off is that gas on Arbitrum usually runs a few cents rather than a fraction of one, which is still modest for most activity. For many users the extra market depth is worth that small step up in cost.
Polygon
Source- Gas
- Usually a fraction of a cent.
- Speed
- About 2-second blocks on a proof-of-stake chain with its own validators.
- Ecosystem
- Low-cost payments, gaming, and enterprise pilots; the native gas token was renamed from MATIC to POL.
Arbitrum
Destination- Gas
- Usually a few cents per swap.
- Speed
- Sub-second confirmations; optimistic-rollup settlement to Ethereum.
- Ecosystem
- The deepest DeFi liquidity of any L2 — perpetuals, GMX, and major DEXs.
Stay safe while bridging
- Approve only what you’re bridging. The widget requests finite token approvals by default — there’s no need to grant an unlimited allowance.
- Check the URL every time. Bookmark this site and confirm the address bar before connecting a wallet.
- Start small for a new route. A tiny test transfer confirms everything works before you move the full amount.
Moving a large amount? Consider a hardware wallet
A hardware wallet keeps your private keys offline, so a compromised browser or a malicious approval can’t drain your funds on its own. It’s the single biggest security upgrade for anyone holding meaningful value on-chain.

Questions about Polygon → Arbitrum
Why do so many people bridge from Polygon to Arbitrum?
Polygon PoS is popular for low-cost payments and gaming, but a lot of the deepest DeFi liquidity now sits on Arbitrum One. People typically make this move to reach venues like GMX and Uniswap, tap larger stablecoin and perpetuals pools, and get tighter pricing than they usually find on Polygon. If your stablecoins or ETH are sitting idle on Polygon and you want them working in more active markets, Arbitrum is a common destination.
I only have POL for gas — can I transact once I arrive on Arbitrum?
Arbitrum One uses ETH for gas, not POL, so you will need a small amount of ETH on the destination side to move your funds after they land. Many bridges let you receive part of the transfer as ETH, or you can bridge a little ETH alongside your main asset. It is worth confirming you have gas on arrival before you start, since POL does not pay for transactions on Arbitrum.
What fees should I expect on this route?
You will usually pay a small gas fee to start the transfer on Polygon, where costs are typically a fraction of a cent, plus whatever the bridge charges for moving liquidity. On the Arbitrum side, later transactions generally cost a few cents in ETH. For smaller transfers the bridge's own spread or fee is often the largest line item, so it helps to compare a couple of quotes before confirming.
How long does bridging from Polygon to Arbitrum take?
Liquidity-based bridges on this route usually complete in well under a few minutes, often around a minute once your Polygon transaction confirms. Polygon's roughly two-second blocks help the source side settle quickly, and Arbitrum confirms in under a second on arrival. Timing still varies with network load and the bridge you pick, so treat any estimate as approximate rather than fixed.
Will my USDC be the same token on Arbitrum?
Stablecoins like USDC exist on both chains, but the exact version you receive can differ — for example a native issuance versus a bridged representation. As of publication it is worth checking which USDC variant a bridge delivers on Arbitrum so it matches the pools or apps you plan to use. Confirming the destination token address before you commit helps you avoid ending up with a version that is harder to trade.
How can I bridge more safely on this route?
Start with a small test amount to confirm the funds arrive as expected before sending the rest. Double-check that your destination is Arbitrum One rather than another Arbitrum network, and verify the token contract on the far side matches the asset you want. Because bridges hold liquidity across chains, sticking to well-reviewed options and reading the quote closely usually reduces surprises.
