SatLayer: Unlocking Bitcoin's Potential as the Economic Layer for Web3

June 9, 2025launch

In the evolving landscape of blockchain technology, SatLayer (@satlayer) is redefining Bitcoin's role by transforming it from a passive store of value into a programmable, yield-generating asset for decentralized finance (DeFi) and beyond. Launched in 2024 by Soul Labs and built on the Babylon protocol, SatLayer is a Bitcoin restaking platform that leverages Bitcoin Validated Services (BVS) to enhance security and liquidity across Web3 ecosystems. With $8 million raised in a pre-seed round and integrations with leading blockchains like Sui and Berachain, SatLayer is paving the way for a new era of BTCFi. This blog post explores SatLayer's core features, use cases, recent updates, and why it's a cornerstone of Bitcoin's DeFi revolution as of June 2025.

What is SatLayer?

SatLayer is a Bitcoin restaking protocol that harnesses Bitcoin's $2.1 trillion market cap to secure decentralized applications (dApps) and infrastructure, making BTC fully programmable. Built on Babylon, a protocol that enables Proof-of-Stake (PoS) blockchains to consume Bitcoin-secured finality, SatLayer introduces Bitcoin Validated Services (BVS)—a counterpart to Ethereum's Actively Validated Services (AVS)—to provide modular security for dApps, bridges, and other Web3 infrastructure. By integrating liquid staking tokens (LSTs) like LBTC (from Lombard Finance), SolvBTC, and UniBTC, SatLayer allows Bitcoin holders to earn yields while retaining liquidity for DeFi applications.

Since its inception, SatLayer has raised $8 million in a pre-seed round led by Hack VC and Castle Island Ventures, with participation from Franklin Templeton, OKX Ventures, and others. Its Phase I Mainnet launch on Babylon Genesis in April 2025 marked a significant milestone, with over $250 million in BTC deposited and partnerships with ecosystems like Sui and Berachain driving adoption. SatLayer's vision is to make Bitcoin the economic backbone of Web3, securing dApps and unlocking new financial opportunities.

Key Features of SatLayer

Bitcoin Validated Services (BVS)

SatLayer's BVS framework allows any dApp or protocol to leverage Bitcoin's security as a trustless economic collateral. This enhances security for DeFi platforms, bridges, and other infrastructure, positioning Bitcoin as a universal security layer akin to EigenLayer for Ethereum.

Liquid Staking Integration

SatLayer supports multiple Bitcoin LSTs, including LBTC, SolvBTC, UniBTC, PumpBTC, and FBTC. Users can stake BTC via partners like Lombard Finance and restake these tokens on SatLayer to earn rewards while maintaining liquidity for DeFi activities like trading and lending.

Cross-Chain Interoperability

Through integrations with Sui (a high-speed Layer-1 blockchain) and Berachain (an EVM-compatible PoL blockchain), SatLayer enables Bitcoin to secure dApps across diverse ecosystems. This eliminates the need for risky bridges and unifies liquidity across chains.

Programmable Slashing

In collaboration with Babylon Labs, SatLayer introduces fully programmable slashing, penalizing malicious or negligent validators to ensure network integrity. This adds a layer of accountability critical for decentralized systems.

Cube: BABY Token Staking

SatLayer's Cube is a liquid staking solution for Babylon's native BABY token. Users stake BABY to receive cBABY, a liquid token usable in DeFi platforms like Tower (Babylon's DEX), enhancing yield opportunities.

Incentivized Testnet and Devnet

SatLayer's devnet, launched alongside its Babylon partnership, provides developers early access to its shared security platform. The testnet rewards users with points for staking and restaking LSTs, with potential conversion to a native token in the future.

Community Engagement

With a growing community on X, SatLayer drives engagement through campaigns like Season 1 Epoch 2, offering boosted rewards (e.g., 4x Sats²) for LST deposits. Posts like @holly_web3's highlight its ranking among top projects on KaitoAI, reflecting strong sentiment.

Use Cases of SatLayer

SatLayer's innovative approach unlocks a range of applications for Bitcoin in Web3:

DeFi Yield Generation

Users can stake BTC to mint LSTs like LBTC and restake them on SatLayer to earn yields, which can be deployed in DeFi protocols for trading, lending, or liquidity provision.

Securing dApps

BVS enables developers to secure dApps on chains like Sui and Berachain with Bitcoin's economic collateral, ideal for AMMs, lending platforms, and NFT marketplaces.

Under-Collateralized Loans

SatLayer's infrastructure supports innovative DeFi use cases like under-collateralized loans, leveraging Bitcoin's security for trustless lending.

Slashing Insurance

By integrating programmable slashing, SatLayer provides mechanisms to protect against validator misbehavior, enhancing trust in PoS networks.

On-Chain Prime Brokerage

SatLayer enables sophisticated financial services, such as on-chain prime brokerage, by combining Bitcoin's liquidity with DeFi scalability.

Gaming and RWAs

Bitcoin's security can be used to safeguard blockchain-based games and real-world asset (RWA) tokenization, expanding BTC's utility beyond finance.

Recent Updates (June 2025)

Mainnet Phase I Launch (April 2025)

SatLayer launched on Babylon Genesis, becoming one of the first restaking dApps with over $250 million in BTC deposited. It introduced Cube for BABY token staking, enhancing ecosystem rewards.

Sui Integration (December 2024)

SatLayer partnered with Sui, a high-speed Layer-1 blockchain, to secure DeFi dApps using Bitcoin's $2.1 trillion market cap. This collaboration leverages Sui's 150 full-time developers to drive BTCFi innovation.

Berachain Collaboration (February 2025)

SatLayer teamed up with Berachain, facilitating the migration of 2,880 BTC ($280 million) to its PoL blockchain. Enhanced incentives, like 4x Sats² rewards, attracted 138,000 pre-deposits, showcasing BTCFi demand.

Season 1 Epoch 2

The second phase of LST deposits opened, allowing users to stake tokens like UniBTC, SolvBTC.BBN, and LBTC for multiple rewards, as announced by @satlayer on X.

Community Traction

SatLayer ranks #6 on KaitoAI's top 100 projects, with X posts from @holly_web3 and @TheDeFiPlug praising its potential to "unlock Bitcoin's full potential" and secure Web3 with programmable mechanisms.

Why SatLayer Matters

SatLayer addresses key Web3 challenges: Bitcoin's underutilization and DeFi security. Despite its $2.1 trillion market cap, Bitcoin has been largely passive in DeFi due to its lack of programmability. SatLayer changes this by enabling restaking, allowing BTC holders to earn yields while securing dApps across chains like Sui and Berachain. Its BVS model, akin to EigenLayer's AVS, leverages Bitcoin's unmatched security to create a universal trust layer, reducing risks like bridge exploits and validator centralization.

With 57,300 BTC ($6 billion) committed to Babylon and $250 million deposited on SatLayer, the protocol is driving BTCFi adoption. Its $8 million raise from investors like Franklin Templeton and partnerships with Lombard Finance, Solv Protocol, and Stakestone signal strong industry backing. Community sentiment on X, such as @KevinWSHPod's simple explanation of SatLayer's yield potential, underscores its accessibility and appeal.

Challenges and Future Outlook

SatLayer faces competition from other BTCFi projects like Lombard Finance and Solv Protocol, as well as Ethereum-based restaking platforms like EigenLayer. Ensuring the security of its slashing mechanisms and scaling cross-chain integrations are critical hurdles. While its testnet and devnet are robust, the lack of a confirmed native token (though hinted at) raises questions about long-term incentives, as noted in community feedback. Users are also cautioned to use official links like satlayer.xyz to avoid scams.

Looking ahead, SatLayer plans to expand to additional Layer-1 and Layer-2 ecosystems, enhancing use cases like slashing insurance and on-chain brokerage. The $BABY token and Cube staking solution will deepen Babylon Genesis integration, while further collaborations could drive BTCFi mainstream. With Galaxy Digital projecting $47 billion in Bitcoin flowing to BTCFi by 2030, SatLayer is well-positioned to lead this shift.
