Babylon Labs has joined forces with SatLayer, a venture backed by Castle Island Ventures, to expand Bitcoin staking and restaking opportunities. This collaboration aims to integrate Bitcoin (BTC) into the decentralized finance (DeFi) ecosystem, leveraging BTC's security and liquidity for cross-chain utility.
Key Benefits of the Partnership
- Enhanced Liquidity: Bitcoin holders gain access to DeFi yields without selling BTC.
- Shared Security: Staked BTC helps secure proof-of-stake (PoS) chains, rollups, and dApps.
- Programmable Slashing: Smart contracts enable punitive measures for validator misbehavior, increasing network reliability.
How SatLayer Enables Bitcoin Restaking
SatLayer’s infrastructure allows Babylon Protocol users to restake their BTC, unlocking additional rewards while maintaining exposure to Bitcoin’s price. The partnership introduces:
- Devnet Access: SatLayer’s newly launched devnet invites developers to build on Bitcoin’s security layer.
- Liquid Staking Tokens (LSTs): Collaborations with Solv Protocol, Lombard, and Bedrock facilitate BTC-backed DeFi participation.
"Babylon Labs and SatLayer share a vision for Bitcoin’s future as the cornerstone of decentralized ecosystems. Together, we enable applications and infrastructure to harness Bitcoin’s unmatched security while expanding its liquidity through programmable restaking frameworks."
— Luke Xie, Co-founder of SatLayer.
Strategic Backing and Ecosystem Growth
Babylon Labs has attracted $70 million in funding led by Paradigm, with additional support from Binance’s venture arm. Recent milestones include:
- $2 billion TVL: Reflecting strong user trust.
- Sui Network Integration: Partnering with Lombard to bring Bitcoin staking to Sui’s ecosystem (November 2025 update).

FAQs
Q: How does Bitcoin staking work in DeFi?
A: Users lock BTC to validate PoS networks, earning rewards while enhancing chain security.
Q: What is programmable slashing?
A: A smart contract mechanism that penalizes malicious validators, ensuring network integrity.
Q: Can I unstake my BTC anytime?
A: Yes, through liquid staking tokens (LSTs), which represent staked BTC and can be traded or redeemed.
