As Bitcoin evolves beyond being merely a store of value, innovative protocols are emerging to boost its utility in decentralized finance (DeFi).

SatLayer is pioneering Bitcoin restaking to provide shared security and sustainable yield generation for decentralized applications (dApps), bridges, oracles, and decentralized exchanges (DEXs).
Built on Babylon’s Bitcoin staking infrastructure, SatLayer introduces Bitcoin Validated Services (BVS), an innovative framework enabling BTC holders to secure modular applications across chains.

Key Features:

→ Restake BTC to secure dApps and infrastructure with programmable slashing for accountability.

→ A shared security marketplace connects restakers, developers, and node operators.

→ Yield generation through restaking unlocks BTC’s potential in DeFi and real-world asset (RWA) protocols.

→ Modular, multi-chain compatibility allows BTC to support rollups and other scaling solutions.

By making Bitcoin programmable and composable, SatLayer extends its utility beyond just HODLing, moving into comprehensive decentralized finance.

Portal tackles one of Bitcoin's long-standing challenges: interoperability.

It enables custodyless atomic swaps of native BTC across blockchains like Ethereum and Solana without relying on wrapped assets or centralized custodians.

Key Features:

→ Trustless atomic swaps of native BTC with over 3,000 assets across chains.
→ A decentralized validator network with 45+ independent PoS validators, secured by Bitcoin.
→ Integrated DEX and wallet for seamless cross-chain trading.
→ BitScaler-powered Layer 3, enabling deep interoperability between L1s and L2s.
→ Mobile-optimized interface for broad accessibility.

Portal removes the need for bridges or wrapped BTC, providing a fully decentralized gateway to cross-chain DeFi while preserving Bitcoin's native integrity.

Both SatLayer and Portal use Babylon for Bitcoin staking, leveraging its secure infrastructure to enhance BTC's role in a modular, decentralized future. Despite this shared foundation, their goals diverge:

Together, these protocols highlight a promising future where Bitcoin is not just part of the broader DeFi landscape but actively securing and engaging with it.
