Our verdict on Cat in a Box
Cat in a Box suits experienced DeFi users who want to explore a niche lending design for yield-bearing assets and are comfortable reading documentation. Its main strength is the self-stabilising approach and its reported Alchemix-linked founders. The main caveat is the lack of listed audits and the small TVL of about $208,000, which together raise smart-contract and liquidity risk. Fee and parameter details were not available, so check them yourself before depositing.

What is Cat in a Box?
Cat in a Box is a dynamic lending protocol on Ethereum for yield-bearing assets. A search snippet says it was built by co-founders of Alchemix. DefiLlama has tracked it since March 2023 and describes it the same way.
TVL stands at about $208,342, up 3.2 percent over seven days, so it is a small protocol. DefiLlama lists no audits and no native token. Public reporting shows a related asset, Cat-in-a-Box Ether (BOXETH), though its exact role is not described publicly.
The homepage could not be fetched, so this review relies on DefiLlama data and search snippets. Other projects called Cat in a Box exist, including a Solana token and a DeSci platform, and they appear unrelated.
How Cat in a Box works
Cat in a Box is a lending protocol. In general terms, users deposit collateral and borrow against it, and the protocol tracks the health of each loan. DefiLlama says it is built for yield-bearing assets, meaning assets that already earn returns, such as staked or interest-bearing tokens.
A search snippet says the protocol self-stabilises by incentivising the conversion of debt from users with unhealthy loans into buying pressure for the protocol's asset. The exact mechanism, supported collateral and parameters are not public, so the official documentation is the place to confirm them.

Pros and cons
What we like
- Focused niche: lending for yield-bearing assets.
- Reported to be built by co-founders of Alchemix.
- Tracked on DefiLlama since March 2023, so it has some history.
- Runs on Ethereum, a widely used and well-supported network.
- Self-stabilising design aims to reduce reliance on external liquidators, per a search snippet.
Watch out for
- No audits are listed on DefiLlama for the protocol.
- TVL is small, at roughly $208,000, which limits liquidity and market depth.
- The homepage could not be fetched, so official documentation was not reviewed here.
- The self-stabilising design depends on user behaviour and market conditions, and its resilience is not proven.
- Fees, collateral rules and liquidation parameters are not published.
- Public reporting mix this project with unrelated tokens named Cat in a Box, which can confuse newcomers.
Cat in a Box fees
Fees are not published. The homepage could not be fetched, and DefiLlama does not list borrowing, interest or protocol fee rates.
Users would normally see interest rates, any protocol charges and liquidation penalties in the app or documentation before opening a position. Ethereum gas fees would apply to every transaction.
Is Cat in a Box safe?
DefiLlama lists no audits for Cat in a Box. Lending protocols rely on smart contracts holding user funds, so unaudited code carries added risk of bugs or exploits. No incidents are mentioned publicly, but absence of information is not proof of safety.
Custody is on-chain and non-custodial in the usual DeFi sense, though admin controls and upgradeability are not described publicly. Small TVL can also mean thin liquidity. Use only funds you can afford to lose and verify everything in the official documentation.
6 steps
How to get started with Cat in a Box
- 1
Find the official website through the project's verified social account and avoid look-alike tokens with the same name.
- 2
Read the documentation on how loans, debt conversion and liquidations work.
- 3
Check for audit reports and review the contract addresses.
- 4
Set up an Ethereum wallet and fund it with a small amount of ETH for gas.
- 5
Start with a small deposit of a supported yield-bearing asset to see how positions behave.
- 6
Monitor loan health regularly, since unhealthy loans are central to how the protocol operates.
Who Cat in a Box is for
This protocol is for experienced DeFi users who understand collateralised loans, liquidation risk and smart-contract risk. It is not suited to beginners or to anyone who requires audited code.
