Our verdict on Endur
6.3/10Endur suits Starknet users who hold STRK or want to earn yield on Bitcoin-linked assets while keeping a liquid token. Its strength is a clear, focused product for a single ecosystem. The main caveat is verification: no audits are listed, fees and rates are not public, and TVL is modest. Read the documentation and check fees in the app before committing funds.

What is Endur?
Endur is a liquid staking protocol on Starknet. DefiLlama describes its main product as xSTRK, a liquid staked version of STRK. The homepage title also references xyBTCs, which it presents as Bitcoin liquid staking tokens.
DefiLlama has tracked Endur since late November 2024. Its total value locked is about 9.9 million USD, down 4.4% over the past week. It lists no token and no audits.
The homepage promises STRK and BTC rewards and says users can stay liquid while earning yield. Beyond that, public sources give few details on rates, fees or team, so this review focuses on what the product category implies and what is not yet verifiable.
How Endur works
Liquid staking lets a user stake a token and receive a receipt token in return. With Endur, staking STRK produces xSTRK, which represents the staked STRK and its accrued rewards. The user keeps a transferable token rather than a locked position.
The homepage also describes Bitcoin liquid staking on Starknet through xyBTCs. The idea is the same: BTC-linked assets are deposited and a liquid token is issued so the holder can earn yield and stay liquid. The specific mechanics, such as how yield accrues or how unstaking works, are not described publicly.
Because the receipt tokens live on Starknet, they may be usable in other Starknet DeFi apps, though specific integrations are not named publicly.

Pros and cons
What we like
- Focused on Starknet, with a clear xSTRK product for STRK holders
- Adds BTC liquid staking tokens, giving Bitcoin holders a way to earn yield on Starknet
- Liquid receipt tokens keep staked positions transferable
- Tracked by DefiLlama since November 2024, so there is some public track record
- No separate token to buy, which keeps the product simple
Watch out for
- No audits are listed on DefiLlama, so security assurances are unverified
- Runs only on Starknet, so it is useful only to people already using that network
- TVL of about 9.9 million USD is modest and fell 4.4% over seven days
- No governance or protocol token is listed, so there is no stated community ownership model
- Fees, withdrawal times and yield rates are not public and must be checked in the app
- Liquid staking adds smart-contract and validator risk on top of normal token price risk
Endur fees
Endur's fee structure is not public we reviewed. No protocol fee, performance fee or withdrawal fee is stated, so we do not quote any figures.
Users would see current fees, exchange rates and any withdrawal conditions in the staking app before confirming a transaction. Network gas fees on Starknet also apply to any on-chain action.
Is Endur safe?
DefiLlama lists zero audits for Endur. Readers should look for published audit reports and bug bounty information from the project before depositing, and treat the lack of listed audits as a risk factor.
Liquid staking carries smart-contract risk, validator or staking risk, and the risk that a receipt token trades below the value of what it represents. Bitcoin-linked assets on Starknet may add bridge or custody risk, which depends on how each asset is issued; the project does not specify this. Only stake what you can afford to lose.
