The Sui Foundation has announced a groundbreaking collaboration with Babylon Labs, Lombard Protocol, and Cubist to bring native Bitcoin staking capabilities to the Sui blockchain. This strategic integration introduces programmable Bitcoin to one of the fastest-growing Layer-1 ecosystems, unlocking access to Bitcoin’s $1.8 trillion market capitalization for decentralized finance (DeFi) applications on Sui.
By combining Babylon’s secure staking infrastructure, Lombard’s liquid staking token (LBTC), and Cubist’s seamless cross-chain framework, this partnership sets a new standard for Bitcoin utility beyond its traditional role as digital gold.
Unlocking Bitcoin’s Liquidity on Sui
Bitcoin has long been recognized for its unmatched security and network effects, but its limited programmability has restricted its use in DeFi. The integration with Sui changes that dynamic. Starting in December, BTC holders will be able to stake their assets through the Babylon protocol and receive LBTC — a liquid staking derivative — minted natively on Sui.
LBTC has already gained significant traction on Ethereum, where it has surpassed $1 billion in total value minted. It is actively used across lending platforms, decentralized exchanges, and yield-generating protocols. Now, with native support on Sui, LBTC is poised to become a foundational asset in Sui’s rapidly expanding DeFi ecosystem.

This innovation allows users to maintain exposure to BTC’s price appreciation while simultaneously using LBTC to earn yields, provide liquidity, or collateralize loans — all without selling or transferring custody of their underlying Bitcoin.
Jameel Khalfan, Head of Ecosystem Development at the Sui Foundation, emphasized the strategic importance of the move:
“Bringing BTC into Sui is a match made in heaven. Thanks to this collaboration, users from all blockchain ecosystems can come to Sui to participate in a thriving financial ecosystem in which Bitcoin will play a key role.”
The integration leverages Sui’s high-throughput architecture and low-latency finality, making it an ideal environment for scalable, composable financial applications powered by Bitcoin-backed assets.
How the Integration Works
The technical implementation relies on a coordinated stack of innovations:
- Babylon Labs provides the underlying staking layer, enabling BTC holders to securely delegate their hash power and earn rewards.
- Lombard Protocol mints LBTC on Sui as a 1:1 representation of staked BTC, ensuring full backing and redeemability.
- Cubist delivers the interoperability layer, managing deposits, staking lifecycle events, and cross-chain messaging with robust security guarantees.
Together, these components create a trust-minimized bridge between Bitcoin’s security model and Sui’s smart contract capabilities.
Fisher Yu, Co-founder and CTO of Babylon Labs, highlighted the broader vision:
“Babylon builds native use cases for BTC to bring Bitcoin security and liquidity to decentralized systems. We are excited to make this a reality on Sui.”
Unlike wrapped or custodial versions of Bitcoin, this approach preserves decentralization and reduces counterparty risk by anchoring staking operations directly to the Bitcoin blockchain via cryptographic proofs.
Expanding Sui’s DeFi Horizon
This partnership significantly enhances Sui’s value proposition as a next-generation DeFi hub. With LBTC now available as a native asset, developers can build lending markets, perpetuals, stablecoins backed by BTC, and other advanced financial instruments.
Moreover, because Sui supports parallel transaction execution and instant finality, DeFi platforms built on this foundation can offer superior user experiences — including sub-second trade settlement and negligible gas fees — compared to older blockchains.

The arrival of programmable Bitcoin aligns perfectly with Sui’s mission: increasing the utility of digital assets through speed, scalability, and developer-friendly tooling.
Strategic Growth of the Sui Ecosystem
Beyond DeFi innovation, Sui continues to strengthen its position at the intersection of traditional finance (TradFi) and Web3. A recent strategic partnership with Franklin Templeton, a global investment management firm, underscores this trajectory. The two organizations are exploring blockchain-based solutions for asset tokenization and financial market infrastructure.
Additionally, novel use cases are emerging on the network. For instance, Chirp recently launched the first decentralized physical infrastructure (DePIN) gaming experience on Sui — a play-to-earn model that connects real-world device usage with blockchain incentives. This demonstrates Sui’s versatility in supporting not just finance, but also gaming, social, and IoT applications.
However, growth hasn’t been without challenges. In a recent incident, Sui experienced a temporary network outage due to a critical bug that disrupted transaction processing. The team responded swiftly, deploying fixes within hours and restoring full functionality.
While the episode highlighted the importance of ongoing scalability testing, it also showcased the foundation’s commitment to transparency and operational resilience — key traits for any blockchain aiming to support institutional-grade applications.
Core Keywords Driving Adoption
This development centers around several pivotal themes shaping the future of blockchain:
- Bitcoin staking
- Programmable Bitcoin
- Sui blockchain
- DeFi innovation

These keywords reflect both user search intent and the technological shift toward making Bitcoin an active participant in multi-chain economies — rather than just a passive store of value.
Frequently Asked Questions
Q: What is LBTC?
A: LBTC is a liquid staking token representing staked Bitcoin. It allows users to retain liquidity while earning staking rewards, and can be used across DeFi applications like lending and trading.
Q: Can I unstake my BTC anytime?
A: Yes. Users can redeem LBTC for native BTC through the Babylon protocol when they choose to exit their position.
Q: Is this staking custodial?
A: No. The Babylon protocol enables non-custodial staking by leveraging cryptographic commitments directly on the Bitcoin blockchain.
Q: Why is Sui a good fit for Bitcoin integration?
A: Sui offers high throughput, low latency, and native asset model that supports complex DeFi primitives — making it ideal for handling BTC-backed financial products at scale.
Q: When does Bitcoin staking launch on Sui?
A: The feature is scheduled to go live in December, pending final testing and security audits.
Q: How does this affect SUI token holders?
A: Increased ecosystem activity driven by BTC integration could boost demand for SUI in areas like gas fees, governance, and liquidity provision.
