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 on Solana means BTC holders can farm yield without wrapping to WBTC or renBTC. the wrapped token tax is finally going away
btc_liquid_ removing the WBTC wrapper tax is huge for DeFi yields. WBTC fees were eating 30-50bps on every bridge. FragBTC native on Solana cuts that to near zero
FragBTC co-launched with Jupiter is smart. Native BTC yield on Solana without wrapped token risks. BTCFi thesis keeps expanding.
fragbtc on solana with jupiter co launch at 94720 btc lets holders farm yield without wbtc tax.
btc_on_sol_ Jupiter co-launch makes sense for liquidity but FragBTC still depends on Solv Protocol custody. the wrapped token risk is reduced but not eliminated
solv custody is the centralized risk vector nobody wants to talk about. fragbtc yield looks great until you remember your btc is sitting in their vault. one audit failure away from a bad time
solv custody remains the big centralized risk even with fragbtc yielding on solana.
custody_skeptic exactly. one solv audit failure and fragbtc goes to zero. people farming 6% yield on their btc are ignoring the 100% counterparty risk
BTC at 94K and people are wrapping it across three chains for single digit yield. the risk reward on BTCFi is genuinely insane when cold storage earns zero risk
Aave considering mETH, cmETH, and MNT as collateral on Mantle. The restaking ecosystem is creating entirely new DeFi primitives.
Dario Rossi Aave onboarding mETH and cmETH on Mantle alongside FragBTC on Solana. liquid staking tokens are becoming the base layer of DeFi
The convergence of Bitcoin liquidity with DeFi yield is the theme of 2025. EigenLayer proved it on ETH, Solv doing it across chains with BTC.
btcfi on solana makes sense but lets see if the yield actually holds. most btcfi protocols are printing rewards from token emissions not real revenue
BTC at 94720 and instead of just holding people wrap it across three chains for 4% yield. the complexity risk alone makes this a bad trade
fragbtc yielding on solana while btc sits at 94k is the trade nobody saw coming 2 years ago. btcfi on solana makes zero sense until you look at the tvl numbers
Solv custody is the centralized chokepoint. FragBTC yield looks great on paper until you realize your BTC sits in their vault. one audit failure and its gone
FragBTC co-launched with Jupiter so the yield basically depends on Jup liquidity staying deep. feels like an LST wrapped in an LRT wrapped in a Solana DeFi position
renzo_burned_ LST wrapped in an LRT wrapped in a Solana DeFi position is three layers of smart contract risk on top of BTC custody. each layer is an attack surface. the 4% yield better be worth it
renzo_burned_ the JUP dependency is the part nobody mentions. if Solana DeFi TVL drops the yield source dries up and youre left holding a derivative of a derivative
BTC at 94720 and people still want yield on top. just hold the thing, you dont need to wrap it across three chains to earn 4 percent
btc_on_sol wrapping btc across three chains for 4 percent yield is the DeFi casino at its finest. just stake it in a multisig cold wallet and sleep fine
jupiter co-launching fragbtc is a liquidity play pure and simple. solana defi needs deep btc pools and jup controls the routing. smart move for both sides
Jupiter co-launching FragBTC is the only reason this has liquidity. without Jup routing the pools would be empty within a week. Solv got lucky with the partnership timing
Anouk V. Jupiter dependency is real but its the custody risk that matters. Solv holds the BTC and issues the receipt. one audit failure and FragBTC goes to zero regardless of Jup liquidity
