The boundaries between Bitcoin and decentralized finance continue to blur as Solv Protocol announced the launch of FragBTC on April 25, 2025 — a liquid restaking Bitcoin token designed to bring native BTC yield to the Solana ecosystem. The development represents another step in the ongoing convergence of Bitcoin liquidity with DeFi yield opportunities across multiple chains.
TL;DR
- Solv Protocol launched FragBTC, a liquid restaking BTC token built on Solana, co-launched with SolvBTC.JUP
- The product enables Bitcoin holders to earn yield on Solana DeFi without selling their BTC exposure
- Ethereum trades at $1,786 while Bitcoin holds near $94,720 amid strong institutional ETF inflows
- Aave governance considers onboarding mETH, cmETH, and MNT as collateral on its Mantle instance
- Liquid staking and restaking continue to dominate DeFi innovation as total value locked climbs
What Is FragBTC?
FragBTC is a liquid restaking token powered by SolvBTC.JUP, co-developed with Jupiter, Solana’s leading decentralized exchange aggregator. The token allows Bitcoin holders to deposit BTC and receive a yield-bearing representation that can be deployed across Solana’s DeFi ecosystem — from lending protocols to liquidity pools and beyond.
The launch addresses a persistent challenge in DeFi: how to unlock Bitcoin’s massive liquidity without requiring holders to convert to wrapped tokens that sacrifice decentralization or security. By leveraging Solv Protocol’s existing SolvBTC infrastructure and Jupiter’s deep Solana liquidity, FragBTC creates a bridge between Bitcoin’s store-of-value proposition and Solana’s high-throughput DeFi environment.
Solv Protocol announced the launch on April 25, emphasizing that FragBTC is designed for native BTC yield generation — a concept that has gained significant traction as restaking protocols like EigenLayer and Ether.fi have demonstrated on Ethereum.
The Liquid Staking Boom Continues
FragBTC arrives during a period of explosive growth in liquid staking and restaking across the DeFi landscape. On Ethereum, protocols like Lido, Rocket Pool, and Ether.fi have collectively locked hundreds of billions of dollars in staked ETH, while EigenLayer’s restaking framework has spawned an entire ecosystem of actively validated services.
The trend is now expanding beyond Ethereum. Solana’s own staking ecosystem has matured significantly, and the introduction of Bitcoin-denominated liquid staking tokens on Solana represents a natural evolution — bringing the largest cryptocurrency by market cap into yield-generating DeFi environments on one of the fastest chains.
Figment, a major staking infrastructure provider, highlighted in research published on April 25 that liquid staking compounds the benefits of traditional staking by providing tokenized representations that remain liquid and composable across DeFi protocols. This composability is precisely what FragBTC aims to deliver for Bitcoin on Solana.
Aave Expands Collateral Options
In parallel DeFi governance activity, Chaos Labs published its risk assessment on April 25 for an Aave governance proposal to onboard MNT, mETH, and cmETH as collateral assets on Aave v3’s Mantle instance. The proposal reflects growing demand for diverse collateral options that span liquid staking tokens, restaking derivatives, and native chain tokens.
Chaos Labs supported the onboarding, noting that beyond liquid staking, the protocol enables restaking through various mechanisms — further evidence that restaking infrastructure is becoming a standard feature across DeFi platforms rather than a niche experiment.
Market Context and DeFi TVL Trends
The DeFi innovation comes as the broader crypto market shows signs of renewed institutional interest. Bitcoin’s price near $94,720 has been supported by record-setting ETF inflows, with $936.43 million flowing into U.S. Bitcoin spot ETFs on April 22 alone. Total ETF net assets surpassed $103 billion, creating a feedback loop where institutional demand drives price appreciation, which in turn attracts more capital into DeFi yield products.
Ethereum at $1,786 remains the backbone of DeFi activity, but the multi-chain thesis is playing out in real time. Solana’s speed and low transaction costs make it an attractive destination for liquid staking innovation, particularly for Bitcoin holders who have traditionally been underserved by DeFi protocols.
The Bigger Picture
FragBTC is not just another token launch — it is evidence of a structural shift in how Bitcoin liquidity interacts with DeFi. For years, Bitcoin holders faced a binary choice: hold BTC and earn nothing, or convert to wrapped assets with varying degrees of counterparty risk. Liquid restaking tokens like FragBTC offer a third path: maintain Bitcoin exposure while participating in DeFi yield generation on a high-performance chain.
As more protocols build cross-chain liquid staking infrastructure, the total addressable market for DeFi expands beyond ETH-native users to include the entire Bitcoin holder base — a pool of capital measured in trillions rather than billions.
Why This Matters
Bitcoin entering Solana DeFi through liquid restaking tokens is a milestone that would have seemed improbable just two years ago. It signals that the tribalism between chains and asset communities is giving way to pragmatic, yield-driven behavior. When Bitcoin holders can earn native yield on Solana, and Ethereum restaking infrastructure inspires similar products on other chains, the entire DeFi ecosystem benefits from increased liquidity, composability, and resilience. The question is no longer whether Bitcoin will participate in DeFi — it is which protocols will capture the most BTC liquidity as it flows in.

FragBTC built with Jupiter is a smart partnership. Using their DEX aggregation for deep liquidity on Solana makes the yield actually sustainable instead of inflationary farming
Native BTC yield on Solana without wrapping is the narrative. EigenLayer proved restaking works on Ethereum, now Solv is bringing that thesis cross-chain.
the SolvBTC.JUP co-launch is interesting. wonder how the yield is actually generated though, the article is light on mechanics
