This guide ranks the best bridges for Arbitrum in 2025 and shows how to bridge safely. Native bridges maximize security but can be slower. Third-party bridges offer speed and asset variety but add smart-contract and routing risk. Use our comparison table, step-by-step HowTo, and the safety checklist.

Quick answer (read first)
- Prefer the official Arbitrum Bridge for larger transfers.
- Use reputable third-party bridges for speed and more assets.
- Bridge the native gas token first so you can transact.
- Verify token contracts; avoid look-alike assets and wrong chains.
- Start with a tiny test, then scale only if it clears.
How to evaluate Arbitrum bridges
Start with security model and asset support. Native bridges rely on the canonical rollup mechanism and official contracts. They minimize trust but can take longer when exiting to L1. Third-party bridges add fast liquidity and better UX, yet they use additional contracts, relayers, or liquidity pools.
Always check audited code, paused events, and incident history. Finally, consider practical factors: supported chains, fee transparency, stablecoin handling, and clear status pages.
Top Arbitrum bridge options — comparison
| Bridge | Model | Chains ↔ | Notable strengths | Key risks | Best for |
|---|---|---|---|---|---|
| Arbitrum Bridge (official) | Canonical rollup bridge | Ethereum ⇄ Arbitrum | Highest alignment with Arbitrum security | Longer L2 → L1 withdrawal window | Larger transfers; conservative users |
| Across | Intent-based + relayer liquidity | Multiple L2/L1 ⇄ Arbitrum | Fast fills; competitive fees | Relayer and oracle dependencies | Quick moves; mid-size transfers |
| Hop | AMM liquidity bridge | Ecosystem L2s ⇄ Arbitrum | Established brand; open docs | Pool liquidity and price impact | Frequent cross-L2 users |
| Stargate | Liquidity network (LayerZero) | Many chains ⇄ Arbitrum | Broad asset reach; deep pools | Endpoint/oracle assumptions | Multi-chain portfolios |
| Synapse | Liquidity bridge + routers | Many chains ⇄ Arbitrum | Wide token coverage | Router complexity; market risk | Alt assets and routes |

How to bridge to Arbitrum (step-by-step)
Objective
Move funds from Ethereum to Arbitrum safely, ensuring you have gas and verified token contracts.
Steps (SOP)
- Pick the route. For large or safety-critical amounts, choose the Arbitrum Bridge. For speed or non-ETH assets, pick a reputable third-party bridge.
- Prepare gas. Ensure a small ETH balance on Arbitrum for fees. If needed, bridge a tiny ETH amount first.
- Verify token. Paste token contract addresses from official sources or explorers. Avoid searching by name.
- Start with a tiny test. Bridge a small amount. Confirm the destination network and address in your wallet.
- Confirm arrival. Check the TX on an Arbitrum explorer. Verify token decimals and balance in the wallet.
- Scale the transfer. Repeat with the full amount only after the test clears and fees look acceptable.
Fees, speed, and common failure points
Total cost includes the source-chain gas, any bridge fee or spread, and the destination claim cost. Speed depends on the chosen model: canonical bridges respect rollup finality, while liquidity bridges settle instantly but reconcile later.
Common issues include selecting the wrong chain route, using a fake token, or lacking destination gas. Keep TX hashes and use official support links if the status stalls.
Safety checklist
- Open bridge URLs from bookmarks or official docs only.
- Confirm destination network and address on your device screen.
- Test with a tiny amount before sending size.
- Keep screenshots and TX hashes until funds arrive.
- Never approve unknown tokens or “infinite” allowances casually.

FAQ
Which bridge is safest for Arbitrum?
The official Arbitrum Bridge aligns best with the rollup’s security model. Use it for conservative or larger transfers.
Why did my withdrawal to Ethereum take longer?
Canonical exits respect the rollup’s challenge window. Liquidity bridges can be faster but add additional trust assumptions.
Do I need ETH on Arbitrum for gas?
Yes. Bridge a small amount of ETH first so you can claim tokens and make transactions.
Can I bridge directly between L2s?
Some third-party bridges support L2⇄L2 routes. Verify the path, fees, and supported tokens before confirming.
How do I avoid fake tokens?
Paste contract addresses from official docs or explorers. Never rely on logos or names alone.
What should I do if the bridge is stuck?
Keep TX hashes, check the project status page, and contact support through official channels.
