Solv Protocol is under the microscope again after an X user said about 50 BTC has been trapped in the protocol for more than two months and still cannot be withdrawn.
On Sept. 29, a user named neil lee wrote that roughly 50 bitcoin was still locked inside Solv Protocol. The post picked up nearly 500,000 views. His line was blunt: "I was chasing your 3% annualized yield, while you were after my entire principal."
Foresight News asked Solv Protocol to explain the situation. Solv said the user’s withdrawal request was stopped after it triggered the platform’s risk-control system. The company said the 50 BTC cannot be released until the case is verified for security reasons, but insisted the assets remain intact and safe.
How the 50 BTC became restricted
According to neil lee, he moved about 50 BTC from Binance on July 8 through the BTC+ yield portal in Binance Web3 Wallet, converted the funds into SolvBTC, and deposited them for a target annualized return of about 3%.
Just five days later, the BTC+ contract on BNB Chain was attacked. After getting hold of the deployer’s private key, the attacker upgraded the minting contract and created BTC+ from nothing. Solv said it quarantined the malicious contract within three hours, burned the unauthorized tokens, and said the underlying bitcoin was untouched, though subscriptions and redemptions were paused for a time.
On July 31, Solv said the function was back online. But when neil lee attempted to redeem, he discovered his address was still on the restricted list. For the next two months, he bounced between Discord, Telegram, and email, submitting proof of fund source and proof of wallet control, yet nothing actually progressed.
$25 million raised, but SOLV has stayed under pressure
Solv Protocol lists YZi Labs, IOSG, and Nomura subsidiary Laser Digital among its backers. Total funding has reached $25 million, enough to make it one of the more familiar projects from the BTCFi surge.
SOLV launched through Binance Megadrop on Jan. 17, 2025, and rose to about $0.2 on its first trading day. That is still its all-time high. Then the slide started. Over the following one year and eight months, the token kept falling. Leaving aside the crash on Oct. 11 last year, the price sank to around $0.002 at its low, a 99% drawdown. It now changes hands around $0.0042, giving it a fully diluted valuation of about $40 million.
And the supply overhang is still there. Out of the 9.66 billion token cap, 5.53 billion are already circulating, which means more than 40% is still waiting to unlock. Some people in the community have argued that SOLV’s weak price performance comes from the large amount of circulating supply that was released at launch.
Public data shows SOLV started with a genesis supply of 8.4 billion tokens, while initial circulating supply stood at 1.4826 billion, or more than 17% of genesis supply. Tokens distributed through Binance Megadrop made up more than 40% of that initial float and were unlocked immediately after the token launch.
A big initial float does not automatically wreck a token if demand is strong enough. But Solv ran into repeated disputes and security issues around the same stretch. Bad timing. Maybe worse than that.
From TVL accusations to contract exploits
In January last year, a Nubit co-founder openly accused Solv of using pre-signed transactions to count the same bitcoin across multiple protocols, making one coin look like three in total value locked calculations, and compared the practice to FTX. Solv rejected the accusation, calling it an organized smear campaign by a competitor and saying it would take legal action.
Around that same period, Solv’s official X account was also hijacked and used to post phishing links. The matter ended with full compensation. Six months later, Solv added Chainlink Proof of Reserve.
In March this year, the BRO vault was exploited through a double-mint bug 22 times. In total, 135 BRO was expanded into 567 million BRO, and the attacker pulled out about 38 SolvBTC worth $2.7 million. Solv fully compensated the affected users, fewer than 10 altogether, and left a 10% bounty for the white hat.
That handling was broadly viewed as orderly. But security researchers said the attacked contract did not seem to appear in any audit report published by Solv. Then came the private-key leak in July. Then the 50 BTC withdrawal fight blew up in September.
The dispute lands as BTCFi loses momentum
The case is getting wider attention because it arrives just as the BTCFi sector has been cooling off fast.
BTCFi had only $300 million in TVL at the start of 2024. Within a year, that number grew 22 times to $7 billion, then climbed to a peak of $9.1 billion in October last year before pulling back across the market. In the first quarter of this year, TVL on Bitcoin L2 sidechains dropped by more than 74%. The broader sector now holds about 91,000 BTC in total, equal to only 0.46% of bitcoin’s circulating supply. For Ethereum DeFi, the comparable figure is 15%.
Data cited in the article says 77% of holders have never used BTCFi. Bedrock’s uniBTC was hit for $2 million two days after launch. Badger DAO shut down eBTC. Several high-profile L2 networks became empty shells in activity terms after their airdrops ended. Total DeFi TVL this year also fell from $115 billion to $70 billion.
The article’s main point is pretty harsh: the sector has been trying to sell a low-yield, structurally complicated product to the most conservative holders in crypto. A 3% annualized return does not make up for the psychological hit from even one security incident. TVL rented with points and airdrops does not easily become sticky capital. Babylon, by contrast, has kept $4 billion locked largely because the model is simpler. No wrapping. No cross-chain transfers. The coins stay where they are.
Bitcoin holders may not need another yield wrapper
In June this year, a lesser-known Bitcoin L2 project called Botanix decided to shut down. The project had been operating for less than a year and pointed to two basic problems in BTCFi: most bitcoin holders see BTC as a reserve asset, not a yield asset, and wrapped bitcoin on Ethereum already covers the existing demand for on-chain financial use.
At the technical level, BTC issued on these Bitcoin L2 networks is not fundamentally different from WBTC on Ethereum. Same basic idea. In both cases, BTC is locked on the Bitcoin main chain and a matching asset is issued on another chain. The difference lies in recovery options. When ETH is used in DeFi, a hacked protocol may still have some chance to freeze assets through contracts. In less mature BTCFi setups, a code-level failure can leave assets permanently unrecoverable.
The article closes on a narrow claim, not a grand one. BTCFi is not necessarily a dead narrative, but the market is nowhere near as big as it was once sold to be. Web3 can live with experimentation. But the cost, it argues, should not be dumped onto ordinary users’ assets.
