LayerZero / Stargate scores 7.8 out of 10 and ranks #7 of 8 in the best cross-chain bridges table, strongest on coverage (9.6) and weakest on exploit history (6.8).
The most widely deployed messaging layer in crypto, with Stargate providing unified liquidity for transfers on top of it. Security depends on the configuration each application chooses, which is flexible for developers and opaque for users.
4 axes, weighted as published in the table’s methodology. Each score below is read from the fact printed under it.
7.2/ 40% of the score
Security depends on the verifier configuration each application chooses; the default set is documented, but an application can run a weaker one and the user cannot see which applies to their transfer. Kelp DAO's adapter ran a single-point verification setup, which is how $292m of unbacked rsETH was minted in April 2026.
6.8/ 25% of the score
No exploit of the messaging protocol's own contracts on record — and the largest DeFi loss of 2026 still came through an application's LayerZero adapter, which is exactly the risk this configurable design pushes onto integrators.
9.0/ 20% of the score
Fast delivery with unified liquidity pools and fees published per route.
9.6/ 15% of the score
Broadest chain coverage of any messaging protocol.
LayerZero does not impose one verification model: each application chooses its own configuration, and the default set is documented. That flexibility is why it reaches more chains than anything else, and it means the security of your transfer depends on a choice made by the app you are using, which you generally cannot see.
Kelp DAO's adapter ran a single-point verification setup. An attacker sent a crafted message and minted 116,500 unbacked rsETH — roughly $292m, the largest DeFi loss of the year. The messaging protocol's own contracts were not exploited, and that is exactly the point worth making: a configurable design pushes the hardest decision onto integrators, and integrators get it wrong.
Unified liquidity through Stargate gives predictable transfer pricing, delivery is fast, and fees are published per route. No protocol-level exploit appears on its record.
Prefer applications that publish their verification configuration, and treat coverage of an obscure chain as a reason for caution rather than confidence — the long tail is where weak configurations live.
Users who need a route nothing else covers, and builders who will configure verification deliberately rather than accept whichever default ships. The flexibility is genuinely valuable to the second group and genuinely dangerous in the hands of the careless.
Not at the protocol level. In April 2026 an attacker exploited Kelp DAO's LayerZero adapter, which ran a single-point verification configuration, to mint about $292m of unbacked rsETH.
Each application chooses its own verifier configuration from the options the protocol supports. The default is documented, but an app can run a weaker setup and users cannot easily tell which applies.
Stargate is a liquidity layer built on LayerZero messaging. It provides unified pools and predictable pricing for transfers, while LayerZero carries the messages.
