Everything about Bitcoin Staking on Starknet

Key Highlights:

• Starknet will enable Bitcoin (BTC) staking directly on its network, adding new utility to BTC.

• This will improve Starknet's security and decentralization by adding BTC to its economic layer.

• BTC will make up to 25% of validator power; STRK remains the main asset, providing at least 75%.

• Endur.fi will create an easy to use liquid staking token as well as dashboard for BTC staking and launch BTC LSTs for different flavours of BTCs (e.g. xWBTC for WBTC, xtBTC for tBTC, xLBTC for LBTC, etc.).

• Launching late Q3 to early Q4 2025

Endur is ready for Starknet’s BTCFi Summer

Bitcoin, the undisputed king of crypto, has long been a store of value. Its original design, however, meant that simply holding BTC offered no native way to earn yield. This posed a problem for those wanting more from their BTC without complex systems.

StarkWare is building a way to bring Bitcoin's value onto Starknet with a setup that minimizes trust (and trustless eventually). BTCfi helps Bitcoin holders put their BTC to use in decentralized finance, doing more than just holding it.

We at Endur.fi, are ready to leverage the new defi summer and will develop:

• BTC Liquid staked tokens (LSTs). These liquid staked tokens can be used on Defi on platforms such as Troves, Vesu, Ekubo, Nostra, etc.

• A dashboard for native staking BTC on Starknet.

Starknet is a powerful ZK-rollup. It uses advanced cryptographic proofs to provide scalability and low transaction fees, all while maintaining the robust security of Ethereum. Its growing DeFi system is a good fit for expanding Bitcoin's use.

How will Starknet integrate BTC in staking

Starknet’s SNIP-31 (Starknet Improvement Proposal) proposes Bitcoin staking using tokenised BTC wrappers on Starknet, letting BTC holders earn STRK rewards. BTC can comprise up to 25% of staking power, boosting Starknet’s security and DeFi composability. STRK rewards for BTC stakers are minted additionally—preserving STRK staker APR and protocol integrity. Supported wrappers and security protections (like entry delays and emergency delisting) are included. This enables BTC participation, unlocks its value, and expands Starknet’s staking ecosystem—all governed transparently and designed to keep STRK holders’ interests central.

You can use different Bitcoin wrappers like WBTC (BitGo), LBTC (Lombard), tBTC (Threshold network), SolvBTC, and PumpBTC. If you believe in Bitcoin and want it to be productive, BTCfi on Starknet is your opportunity.

How do you stake Bitcoin on a network like Starknet?

At Endur.fi, we've learned from xSTRK's success, the leading liquid staking token for STRK. We're now using that experience to help Bitcoin holders in the BTCfi space.

Liquid Staking:

You can easily liquid stake your BTC by heading to Endur.fi.

Key benefits with liquid staking:

1. Unlock liquidity: Stake and still access DeFi. e.g. use your BTC LSTs on lending platforms.

2. BTC-Based Rewards: Rewards are automatically converted to BTC

3. Faster Unstaking
   Withdrawals are quicker than (most times) native staking via automated deposit-withdrawal matching. Learn more.

4. Isolated risk: Each LST is tied to its BTC wrapper only — no contagion

5. Exceptional Support
   Real humans. Real help. Fast.

6. Dead-Simple UX
   You stake. We handle everything else — choosing validators, rewards, logistics.

Native staking:

Endur operates one the most powerful native staking dashboard for Starknet, which is data rich and also enables native stakers to stake, unstake, switch validators and track their portfolio. To make staking easy, we will support BTC as well on this dashboard.

Our goal is to make earning yield on your BTC simple for every defi user.

FAQs

1. Will I earn rewards in BTC? With native staking, rewards are paid in STRK. With Endur’s liquid staking, rewards are auto-converted to BTC wrappers and re-staked — enabling seamless auto-compounding in BTC. It's built to be simple and reliable — helping secure Starknet while letting your BTC earn yield.

2. Will Endur LST be supported from day 1 of BTC staking? Yes

3. Is Endur audited? Yes. Endur only deploys audited contracts to mainnet. All audit reports are publicly available here.

4. Is Endur open-source? Not yet. As of August 2025, Endur is not open-source. We plan to open the code once Starknet achieves full decentralisation, enabling final contract versions and multiple comprehensive audits. For latest information, check our github. If you have any concerns on this, please reach out to us on Telegram.
