The rapidly evolving decentralized finance (DeFi) landscape is witnessing a groundbreaking convergence: Bitcoin’s unmatched security and liquidity are now being harnessed within high-performance ecosystems like Sui. With the recent integration of SatLayer, a leading Bitcoin restaking platform, developers on Sui gain unprecedented access to Bitcoin’s capital efficiency and robust security model—ushering in a new era of BTCfi (Bitcoin Finance) innovation.
This strategic collaboration positions Sui as a premier destination for BTCfi, combining the stability and depth of Bitcoin’s $1 trillion+ asset base with Sui’s lightning-fast transaction speeds, horizontal scalability, and developer-friendly Move programming language. As restaking protocols mature, this integration marks a pivotal step toward unlocking Bitcoin’s dormant potential beyond simple store-of-value use cases.
🔗 Bridging Bitcoin’s Security with Sui’s Performance
At the core of this advancement is SatLayer’s integration with Babylon, the pioneering protocol enabling Bitcoin staking and restaking without modifying Bitcoin’s base layer. As Babylon’s designated restaking partner, SatLayer deploys its infrastructure as smart contracts on Babylon Chain, allowing applications on compatible Layer 1 networks—like Sui—to inherit Bitcoin-level security through programmable slashing conditions.

This means that DeFi primitives such as bridges, decentralized exchanges (DEXs), lending protocols, and oracles built on Sui can now be secured by Bitcoin itself. By staking BTC via Babylon and restaking those assets through SatLayer, users contribute to the economic security of multiple chains while earning yield—a paradigm shift from passive holding to active participation in cross-chain safety.
🚀 Powering the Sui BTCfi Ecosystem
SatLayer isn’t acting alone. It’s partnering with some of Sui’s most influential protocols to accelerate BTCfi adoption:
- Navi Protocol: A leading lending and borrowing platform exploring Bitcoin-backed credit markets.
- Suilend: Integrating Bitcoin liquidity to enhance capital efficiency across lending pools.
- Cetus & Aftermath: DEX innovators enabling seamless BTC trading with low latency and deep order books.
- Ika: Focused on cross-chain interoperability and secure asset bridging.
These collaborations aim to demonstrate practical use cases for Bitcoin Validated Services (BVS)—a framework where services are secured by Bitcoin stakers. For instance, a bridge verifying cross-chain transfers could be protected by validators bonded with restaked BTC, drastically reducing the risk of exploits.
Jameel Khalfan, Global Head of Ecosystem at the Sui Foundation, emphasized the strategic importance:
“Sui’s move into Bitcoin DeFi reflects our commitment to becoming the go-to hub for BTCfi. When you combine Bitcoin’s scale and security with Sui’s speed and scalability, entirely new possibilities open up for builders and users alike.”
💡 Unlocking Capital Efficiency with Liquidity Restaking Tokens (LRTs)
One of the most transformative aspects of SatLayer’s approach is the introduction of Liquidity Restaking Tokens (LRTs) on Sui. Unlike traditional staking derivatives, LRTs represent not only staked value but also active participation in securing external systems.
SatLayer leverages Bitcoin Liquid Staking Tokens (LSTs) from partners like Lombard Finance and Lorenzo Protocol, which tokenize staked BTC positions. These LSTs are then restaked via SatLayer to secure Sui-based applications, generating additional yield streams while maintaining liquidity.
This dual-yield mechanism enhances capital efficiency—an essential factor in competitive DeFi environments. Developers can now build protocols that offer:
- Higher collateralization ratios using Bitcoin-backed assets
- Reduced reliance on native token inflation
- Improved trustlessness through Bitcoin-secured operations
Luke Xie, Co-Founder and CEO of SatLayer, highlighted the synergy:
“Sui is the ideal Layer 1 to leverage Bitcoin’s unparalleled security and liquidity. From Bitcoin restaking to application-level liquidity provisioning, this partnership unlocks incredible possibilities for builders and users on Sui.”
🔐 A Secure Future for Cross-Chain Applications
Fisher Yu, CTO of Babylon Labs, underscored the broader implications:
“We’re thrilled to play a key role in bringing Bitcoin to Sui. By combining Babylon’s Bitcoin staking with SatLayer’s restaking framework, the Sui ecosystem now has the foundational building blocks for a powerful on-chain Bitcoin DeFi ecosystem. This is a major step toward our vision of a securely decentralized world powered by Bitcoin.”
This vision hinges on decentralization without compromise. Unlike many cross-chain bridges that rely on centralized custodians or small validator sets, the SatLayer-Babylon-Sui stack ensures that security scales with Bitcoin’s hash power—making attacks economically infeasible.

🔍 Frequently Asked Questions (FAQ)
Q: What is BTCfi?
A: BTCfi stands for Bitcoin Finance—referring to financial applications that utilize Bitcoin not just as an asset, but as a source of security, liquidity, and programmability in DeFi ecosystems.
Q: How does Bitcoin restaking work on Sui?
A: Through Babylon and SatLayer, users stake BTC and then "restake" it to secure other chains or applications. This process issues LRTs that can be used across Sui-based protocols while contributing to network security.
Q: Are my funds safe when using LRTs or LSTs?
A: Yes—these tokens are backed by real staked BTC and secured via cryptoeconomic incentives tied to Bitcoin’s consensus. Protocols undergo rigorous audits, though users should always assess individual project risks.
Q: Can I earn yield from both staking and using LRTs in DeFi?
A: Absolutely. LRTs enable dual yield—earning rewards from Bitcoin staking while also generating returns through lending, liquidity provision, or governance participation on Sui.
Q: Is this integration changing Bitcoin itself?
A: No. All innovations occur on external chains like Babylon and Sui. Bitcoin’s base layer remains unchanged, preserving its security and decentralization.
Q: Which wallets support BTCfi activities on Sui?
A: Compatible Web3 wallets like Sui Wallet, Ethos, and Fewcha are integrating support for LRTs and cross-chain BTC interactions.

🔚 The Road Ahead for Sui and BTCfi
The integration of SatLayer into Sui represents more than a technical upgrade—it's a philosophical shift toward a future where Bitcoin actively secures the decentralized web. With prior announcements of Bitcoin staking coming to Sui in late 2024, this development solidifies its trajectory as a leader in next-generation DeFi infrastructure.
As more developers adopt BVS models and launch innovative BTCfi products—from insured bridges to self-custodial lending markets—the ecosystem will grow in depth and resilience. The combination of Move language safety, Sui’s parallel execution engine, and Bitcoin-backed security creates a compelling stack for sustainable Web3 innovation.
For users, this means safer protocols, higher yields, and broader access to Bitcoin’s economic power without sacrificing decentralization. For builders, it offers a rich toolkit to create truly trustless financial services anchored in the most secure blockchain ever built.
