Introduction
Decentralized Finance (DeFi) on Bitcoin is no longer theoretical. Despite early challenges, momentum is building to unlock Bitcoin's potential beyond being "digital gold." While Ethereum developed a robust DeFi ecosystem, Bitcoin remained sidelined—until now. Over $1.5 trillion in liquidity sits idle in cold wallets, but new protocols are changing that. Here’s how projects like Babylon, Lombard, SatLayer, and Solv Protocol are laying the groundwork for native BTC DeFi.
The Emerging BTC DeFi Stack
Babylon: Bitcoin’s Staking Layer
- Role: Native BTC staking protocol (~$50B TVL).
Innovation:
- Allows direct BTC staking on Bitcoin’s mainnet without bridging/wrapping.
- Extends Bitcoin’s security to other blockchains (EVM chains, rollups, appchains).
- Use Case: Holders earn rewards by securing external networks.

Lombard: Bitcoin’s Liquid Staking
- Role: BTC’s answer to Lido ($19B TVL).
Function:
- Issues LBTC (liquid staked BTC) via Babylon.
- Enables DeFi activities (trading, lending, yield farming).
- Ecosystem: Integrated with Aave, Pendle, and Base/Sonic/Sui networks.
SatLayer: Bitcoin’s EigenLayer
- Role: Re-staking for application-layer security ($340M TVL).
Model:
- Re-stake LBTC to secure apps (e.g., oracles, rollups).
- Earn rewards directly from protected protocols.
- Networks: Supports EVM and Sui.
Solv Protocol: BTC Reserve Strategies
- TVL: $524M.
Approach:
- Independent of Babylon.
- Focuses on institutional-grade BTC reserves and DeFi vaults.
- Token: SolvBTC represents staked BTC (custodied via centralized partners).
The Big Picture
- Babylon: Base consensus layer.
- Lombard: Adds liquidity.
- SatLayer: Enables re-staking for dApps.
This mirrors Ethereum’s staking ecosystem (Beacon Chain → Lido → EigenLayer), but for Bitcoin.

Future Outlook
- EVMs on Bitcoin: Projects like Botanix could boost composability.
- Unlocking Idle BTC: Billions may soon act as active collateral.
- Key Challenge: Lombard/SatLayer depend on Babylon—centralization risks?
FAQ
Q: Is Bitcoin DeFi secure?
A: Yes—protocols like Babylon use non-custodial staking, keeping BTC on-chain.
Q: Can I earn yield on native BTC?
A: Absolutely. Lombard (via Babylon) and Solv offer liquid staking options.
Q: What’s the advantage over wrapped BTC (wBTC)?
A: Native solutions avoid Ethereum’s gas fees and smart contract risks.
Q: Which chains support BTC DeFi?
A: Base, Sui, Sonic, and EVM-compatible Bitcoin sidechains.
Conclusion
Bitcoin DeFi is transitioning from theory to practice. With staking, liquid tokens, and re-staking, BTC’s $1.5+ trillion liquidity could fuel a new era of decentralized finance—natively. Watch for EVM-compatible Bitcoin chains to accelerate adoption.
