Sushi BentoBox Review 2026: The Vault Layer Under Sushi Apps

Sushi BentoBox is a token vault that generates yield on the capital deposited into it. It was built as a shared base layer: protocols such as Kashi, Trident, Limit Order and Furo can be built on top of it. It belongs to the Sushi ecosystem, which also runs a swap and aggregator front end.

The vault is listed on nine networks: Ethereum, Arbitrum, Polygon, Optimism, Avalanche, Gnosis, Moonbeam, Moonriver and Celo. Total value locked is about $2.4 million, up about 3.1% over seven days. It has been tracked since October 2022, and the SUSHI token is associated with it.

The main caveats are scale and assurance. The deposit base is modest, no audits are listed in the tracking data, and the project does not publish BentoBox-specific fees on its homepage.

A token vault holds assets in one shared contract instead of each app keeping its own pool. Apps built on top use balances recorded in the vault. The vault can put idle tokens to work to earn yield, which accrues to the capital deposited.

The project names four protocols built on this base: Kashi, Trident, Limit Order and Furo. For a user, that means one deposit layer can sit beneath lending, trading and other functions. The exact strategies used to generate yield are not described on the homepage.

The Sushi site itself presents a swap interface with an aggregator, plus tabs for perps, a launchpad, positions and staking. BentoBox is the underlying piece rather than the front door, so most people meet it through those apps.

BentoBox-specific fees are not published in the sources reviewed. Any yield strategy or app built on top may take its own cut or charge its own trading or borrowing fees, and the project does not state them for the vault itself.

On the Sushi swap interface, fee and network fee lines appear in the trade details, along with slippage, price impact and minimum received. Users should read these before confirming, and check each app's documentation for its own charges.

The tracking data lists no audits for BentoBox, and the homepage does not mention any. Funds are held in smart contracts, so the main risks are bugs, exploits and dependence on the apps built on top. A shared vault design means a flaw could affect more than one product.

The project publishes no BentoBox-specific information about team, insurance or incidents in the sources reviewed. The Sushi site references Sushi Labs in its cookie policy. Users should check the project's documentation and any security disclosures, keep deposits to amounts they can afford to lose, and verify that DeFi use is permitted where they live.

BentoBox is for experienced DeFi users who use Sushi apps and want to know how deposits and yield work underneath. It is less suited to beginners looking for a simple interface, or to anyone who needs audited, insured products.
