Best Crypto Bridges

Best crypto bridges by use case

• You want to know the fee before you ask for a quote: deBridge scores 9 for fee transparency. It publishes a flat fee for each of 18 source chains, paid in that chain's gas token (0.001 ETH on Ethereum, 0.015 SOL on Solana), plus 4 basis points of the amount sent. Chainflip also scores 9: its docs itemize a 0.10% network fee (0.01% on stablecoin swaps, $0.50 minimum) and pool fees of 0.10% to 0.15% per leg.
• You want a stated signing threshold: Wormhole scores 10 for trust model disclosure. Its 19 guardians need 13 signatures for a valid message, and the docs say 7 can censor. Chainflip also scores 10: 100 of its 150 validators must sign for any vault, and the docs say a 3-of-6 governance key can trigger Safe Mode.
• You prefer an optimistic design over a signer set: Across scores 10 on the same criterion. Transfers settle in bonded bundles on Ethereum, which can be disputed through UMA's Optimistic Oracle. It drops to 7.2 overall on a fee formula with no published rates and a BUSL licence that runs until 27 July 2027.
• You want open-source code and a deep audit record: Axelar scores 10 on both. The code is under Apache 2.0, and the audit archive holds 61 dated reports from ten firms, November 2021 to August 2026. The GPL-3.0 code of Celer cBridge also scores 10 on licence, as does the Apache-licensed code of Chainflip.
• You want one interface that routes over several bridges: Squid settles through its own intents system or hands off to Axelar, Chainflip, Circle's CCTP or LayerZero. Its audit record scores 8, with four named firms and linked reports. It scores 2 on licence, though, because its router contracts are not in any public repository.

How the ranking works

Each bridge gets a 0 to 10 mark on five criteria from the published rubric. On 6 November 2026 every mark was checked against a single scale per criterion, so the same evidence earns the same mark from one bridge to the next.

• Fee transparency: the cost published as figures. A per-chain fee table or an itemized fee schedule scores 9 (deBridge, Chainflip). Celer cBridge gets 7 because its FAQ gives a 0%–2% protocol fee ceiling and its fee section gives 0%–0.5%. Squid gets 6 for a convenience fee on some routes with no published rate. A fee charged on every transfer and explained only as components, with no rate, scores 5 (Axelar, Wormhole, Across, Stargate). A fee that appears only inside each quote scores 2 (Synapse).
• Trust model disclosure: what secures a transfer, in the protocol's own words. A stated quorum or challenge mechanism with its weak points named scores 10. A described mechanism with no validator count or threshold scores 6 (deBridge). A settlement flow with no failure case stated scores 5 (Squid).
• Licence & code openness: read from the repository file. A recognized open-source licence stated in full scores 10. The same licence loses one point when it is a short-form notice (Wormhole) or rests on per-file headers with no LICENSE file (Synapse). A BUSL licence past its change date, where the GPL change licence now applies by its own terms, scores 8 (deBridge). A BUSL licence before its change date scores 4 (Across). A licence with no change licence, one whose text says it is not open source, or no public repository for the core contracts at all scores 2 (Stargate, Squid).
• Chain coverage: networks the protocol lists in its own documentation, with per-product tables counted as a list. Twenty-five or more documented networks score 9. The 18 and 19 listed by deBridge and Synapse score 7, and Chainflip's eight score 5.
• Audit disclosure: reports published with the firms named. A large dated archive from many named firms scores 10 (Axelar, Wormhole). Named, linked reports score 7 to 9 depending on dates and depth: deBridge's 33 dated reports score 9, Across's eight undated reports 8 and Celer's five undated reports 7. Reports that sit in a code repository with no link from the docs score 5 (Synapse). Audits recorded only by the auditor, with no firm named in the protocol's own docs, score 4 (Chainflip).

The overall score is the plain average of the five marks, rounded to one decimal, with equal weight for each. For deBridge that is (9 + 6 + 8 + 7 + 9) / 5 = 7.8. Ties are listed alphabetically, which is why Axelar appears above Wormhole at 8.6. The marks come from desk research of each protocol's documentation, repositories and audit pages, checked on 6 November 2026. We did not send transfers. Marks are re-checked, and each review logs every change with its reason and source.

What changed in this update

The previous edition, checked on 24 July 2026, ranked ten bridges. In this November 2026 update, eight of the remaining nine moved:

• Chainflip, up to 7.6 from 4.6: its governance and security pages returned errors in July. They now state the 100-of-150 vault threshold (trust model 2 to 10); fees, chains, audits and licence also rose.
• deBridge, up to 7.8 from 5.4: its security overview now links a repository of 33 audit reports (audits 2 to 9). The BUSL change date has passed, so licence rose from 4 to 8.
• Synapse, up to 5.8 from 3.4: its documentation now loads. It covers the Intent Network's dispute model (trust 2 to 6), lists 19 networks (chains 2 to 7), and named audit reports sit in its code repository, though the docs do not link them (audits 2 to 5).
• Celer cBridge, up to 8.4 from 6.2: its audit page now loads and links five reports (2 to 7), and its homepage states 40+ chains (3 to 9). Fees fell from 8 to 7 because of the conflicting fee ceilings.
• Wormhole, up to 8.6 from 6.8: per-product network tables raised chain coverage from 3 to 9, and audits rose from 9 to 10.
• Squid, up to 6.0 from 4.8, and Stargate, up to 6.6 from 6.0: Squid gained on audits (2 to 8) but fell on fees (9 to 6). Stargate's own V2 fees page says its flat 6 bps fee applied to V1 pools, which took fees from 9 to 5. Its V2 network list raised chain coverage from 2 to 9.
• Across, down to 7.2 from 7.4: fees went from 6 to 5 under the single fee scale. Axelar was unchanged at 8.6.

Hop Protocol was withdrawn: its bridge app and API are offline, and the hop.exchange domain serves an unrelated site.

What the scores do not cover

• Speed and the price you actually pay: we did not measure either. Settlement times on these pages are the companies' own figures, such as Across's under two seconds, deBridge's 10 to 60 seconds and Celer's 5 to 20 minutes.
• Incident history: the rubric scores incidents only when a protocol documents them itself. Wormhole's Governor design document records the 2 February 2022 exploit of its Solana core contract. "Zero exploits" lines on other sites are those companies' own statements.
• Who runs the protocol: on 15 December 2025, Axelar's blog said Circle had agreed to acquire the Interop Labs team. Across's forum said on 17 September 2026 that the protocol had passed to Across, Inc. Synapse's domain now redirects to an options venue. Celer names no legal entity. None of this changed a mark.
• Liquidity and liveness: pool depth, credit limits on a route and relayer availability can cap or delay a transfer.
• Access: some terms exclude certain users. deBridge's terms, for example, exclude US persons.
• The connected chains: a bridge cannot be safer than the chains at either end of it.

How to choose

1. Confirm that both chains and the asset appear in the protocol's own supported-network list, not only in a third-party app.
2. Compare the amount you send with the amount quoted to arrive. For bridges that publish no rates, the quote is the only price you get.
3. Find out what secures your route. On Stargate the DVN set can differ by route. On Squid it depends on which underlying bridge settles the transfer.
4. For a large amount, look for per-chain limits or delays, such as Wormhole's 24-hour Governor delay or Celer's quarantine for larger transfers.
5. Check the terms for country restrictions, and use only the official app address.

Our guide to how bridges work and why they are risky explains the validator, optimistic and pool designs in general terms.

Is a higher-ranked bridge safer to use?

Not necessarily. The score measures how much a bridge discloses about fees, security, licence, coverage and audits, not whether its contracts are free of bugs. A clearly documented trust model tells you what you are relying on, but it does not make that assumption hold. An audit is a review at a point in time, not insurance.
