Best Cross-Chain Bridges · Rank 01 of 8
Fast transfers where the risk sits with a solver, not with you
Last verified August 12, 20264 scored axes
Documented and independently verifiable
Across scores 9.2 out of 10 and ranks #1 of 8 in the best cross-chain bridges table, strongest on trust assumptions (9.4) and weakest on coverage (8.0).
An intents design where relayers front the destination funds and are reimbursed later against a canonical settlement layer, so the user is not exposed to the bridging window. Fast, cheap, and no exploit history to date.
4 axes, weighted as published in the table’s methodology. Each score below is read from the fact printed under it.
9.4/ 40% of the score
Relayers pay the user on the destination chain from their own capital and are reimbursed later through a canonical settlement layer, so the user is not exposed during the bridging window; disputes resolve through an optimistic oracle.
9.4/ 25% of the score
No security incident affecting user funds on record since 2021; audits published.
9.4/ 20% of the score
Delivery on major routes typically completes in seconds to minutes, with fees published per route as a relayer fee plus gas.
8.0/ 15% of the score
Covers Ethereum and the major rollups; the chain list is narrower than the general messaging protocols.
In a conventional bridge, your assets are locked while a message travels and you carry the exposure until it arrives. Across inverts that: a relayer pays you on the destination chain from their own capital and is reimbursed afterwards through a canonical settlement layer, with disputes resolved by an optimistic oracle. The person exposed during the bridging window is a professional who chose to be, not you.
Bridges have lost more user funds than any other category in crypto, and the losses clustered in one shape: a large pool of collateral behind a small set of signers. Across does not maintain that honeypot in the same way, which is a structural answer rather than a promise to be careful. No security incident affecting user funds appears on its record since 2021.
Delivery on major routes typically completes in seconds to minutes, with fees published per route as a relayer fee plus gas — usually cheaper than the canonical route once you price the waiting.
Chain coverage is narrower than the general messaging protocols: Ethereum and the major rollups rather than everything. And on very large transfers, delivery depends on solver capital being available to front it.
A relayer pays you on the destination chain out of their own funds and is reimbursed later through a canonical settlement layer, with an optimistic oracle resolving disputes. You are not exposed during the bridging window.
No security incident affecting user funds appears on its record since 2021, and its design avoids the large pooled collateral that most exploited bridges held. Its audits are published.
Ethereum and the major rollups. Its coverage is narrower than messaging protocols like LayerZero or Wormhole, which is the trade for its risk model.
