Solana Quietly Fixes Bug That Could Have Let Attackers Mint and Steal Certain Tokens

The Solana Foundation has disclosed a previously unknown vulnerability in its privacy-focused token system that could have allowed attackers to forge fake zero-knowledge proofs, enabling unauthorized minting or withdrawals of tokens.
The vulnerability was first reported on April 16 through Anza’s GitHub security advisory, accompanied by a working proof-of-concept. Engineers from Solana development teams Anza, Firedancer, and Jito verified the bug and began working on a fix immediately, per a post-mortem published Saturday,
The issue stemmed from the ZK ElGamal Proof program, which verifies zero-knowledge proofs (ZKPs) used in Solana’s Token-22 confidential transfers. These extension tokens enable private balances and transfers by encrypting amounts and using cryptographic proofs to validate them.
ZKPs are a cryptographic method that lets someone prove they know or have access to something, such as a password or age, without revealing the thing itself.
In crypto applications, these can be used to prove a transaction is valid without showing specific amounts or addresses (which can otherwise be used by malicious actors to plan exploits).
The bug occurred because some algebraic components were missing from the hashing process during the Fiat-Shamir transformation — a standard method to make zero-knowledge proofs non-interactive. (Non-interactive means turning a back-and-forth process into a one-time proof anyone can verify.)
A sophisticated attacker could forge invalid proofs that the on-chain verifier would still accept.
This would have allowed unauthorized actions such as minting unlimited tokens or withdrawing tokens from other accounts.
As such, the vulnerability did not affect standard SPL tokens or the main Token-2022 program logic.
Patches were distributed privately to validator operators beginning April 17. A second patch was pushed later that evening to address a related issue elsewhere in the codebase.
Both were reviewed by third-party security firms Asymmetric Research, Neodyme, and OtterSec. By April 18, a supermajority of validators had adopted the fix.
There is no indication that the bug was exploited, and all funds remain secure, according to the post-mortem.

Michael Saylor’s Strategy Adds 1,895 Bitcoin, Bringing Company Stack to 555,450 BTC

Led by Executive Chairman Michael Saylor, Strategy (MSTR) added modestly to its bitcoin holdings last week.
The company purchased 1,895 BTC for $180.3 million, or an average price of $95,167 each, according to a Monday morning SEC filing.
The buys were funded via sales $128.5 million of common stock and $51.8 million of STRK preferred stock. The common stock sale notably used up the remainder of MSTR’s 2024 $21 billion at-the-market offering. MSTR last week introduced a new $21 billion ATM offering.
Strategy now holds 555,450 bitcoin purchased for $38.08 billion, or an average price of $68,550 each. At bitcoin’s current price around $94,000, the holdings are worth north of $52 billion.
MSTR is lower by 2.7% in premarket action.

Vitalik Buterin Wants to Make Ethereum as Simple as Bitcoin

Ethereum co-founder Vitalik Buterin is calling for a major simplification of the protocol, aiming to reduce its complexity to a level closer to Bitcoin’s while preserving its unique strengths in programmability and scalability.
In a blog post published Saturday, Buterin argued that Ethereum’s growing technical sprawl — from its consensus mechanisms to its virtual machine — has made it harder to maintain, audit, and onboard new developers.
He proposed a multi-year strategy to shrink Ethereum’s “consensus-critical” codebase and reduce the risk that the protocol becomes too technocratic and fragile.
“Even a smart high school student is capable of fully wrapping their head around and understanding the Bitcoin protocol,” Buterin wrote. “A programmer can write a client as a hobby project.”
High complexity
Ethereum’s base layer has become increasingly complex due to feature additions, new consensus designs, and legacy code requirements. While this has enabled powerful use cases like smart contracts and zero-knowledge proofs, it has also increased the risk of bugs, made protocol upgrades harder, and raised the barrier for new developers.
In contrast, bitcoin’s core protocol remains relatively unchanged and minimal: blocks, transactions, proof-of-work, and coin outputs.
Area of simplification proposed by Buterin includes an overhaul of Ethereum’s current consensus layer (the “beacon chain”), which involves complex mechanics like epochs, slot shuffling, and sync committees.
Another is patching the Ethereum Virtual Machine (EVM) incrementally, but eventually replacing it entirely with a simpler virtual machine like RISC-V. This lightweight, open standard could bring performance boosts for zero-knowledge provers and drastically reduce code complexity.
However, one of the main challenges is preserving backwards compatibility with existing Ethereum applications.
Buterin outlined a phased approach where the current EVM and the new VM could run side-by-side, and legacy functionality could be moved into “non-consensus” layers.

Crypto Daybook Americas: Bitcoin Dips, but ETF Inflows, Fed Week Keep Bulls Interested

By Omkar Godbole (All times ET unless indicated otherwise)
The outlook for bitcoin (BTC) looks bullish even after the largest cryptocurrency pulled back to $95,000 from Friday’s highs above $98,000 and the total crypto market capitalization dropped under $3 trillion
Among the signals, U.S.-listed spot bitcoin ETFs are rapidly absorbing supply. Last week, the 11 ETFs registered a cumulative net inflow of $1.8 billion, equating to over 18,500 BTC, six times more than the 3,150 BTC mined, according to data sources Farside Investors and HODL15Capital. (See Chart of the Day)
On-chain activity has also picked up, suggesting a bullish outlook. According to data source IntoTheBlock, the number of active BTC addresses topped 800,000 on Sunday, «While it is still far from its highs, the rebound signals a clear pickup in on-chain engagement; often a sign of renewed market demand,» the firm said on X.
As for DeFi, the number of on-chain transactions involving wrapped bitcoin (WBTC) continues to rise, having doubled since January, indicating investor interest in bitcoin-backed decentralized finance.
Still, long-term holders may step up their selling as the price nears $100,000, potentially slowing rate of increase, analysis from Glassnode shows.
In ether’s (ETH) case, data from CryptoQuant show that the number of ETH held by the so-called accumulation addresses increased by 22% to 19.04 million ETH in two months. Ethereum is set to implement the Pectra upgrade on Wednesday to boost scalability, usability and validator efficiency, doubling the blob data capacity per block and lowering the costs for layer-2 protocols.
On the macro front, the Federal Reserve interest-rate decision is due this Wednesday. According to ING, the near-term inflation concerns, highlighted by survey data, limit the Fed’s ability to ease and the central bank is likely to push back against the calls for rate cuts. The bank, however, said that the recent softening of the GDP suggests scope for easing in the second half.
«Volatility is coming,» PowerTrade said, pointing to the Fed decision, U.S. ISM services PMI and the Bank of England rate decision as catalysts this week. Stay alert!

Token Talk
By Shaurya Malwa
- Memecoin markets are not attracting celebrity hype anymore.
- Prices of the GORK token, which references a parody AI chatbot that itself mimics XAI’s Grok chatbot, failed to jump higher over the weekend even as technocrat Elon Musk widely referenced the Gork X account.
— gorklon rust (@elonmusk) May 3, 2025
- Musk even changed his X picture to the one used by Gork. He later added pit viper sunglasses — a reference to Mog Coin — after a MOG holder asked Musk to «put those» on.
- GORK, which was issued last week, zoomed to an $80 million market capitalization in four days, but did not rise after Musk’s references, a possible sign of fatigue among memecoin speculators. Such an endorsement last year would probably have led to a massive spike in prices.
- That muted reaction highlights a broader shift in memecoin dynamics: Celebrity engagement no longer guarantees price momentum. In 2023 and early 2024, even a single tweet or like from high-profile figures could trigger double- or triple-digit percentage gains in minutes.
- But the market has since matured, or, arguably, burned out. Now, traders seem more focused on liquidity depth, tokenomics and narrative stickiness than quick-hit endorsements.
- GORK’s stalled reaction, despite Musk’s implicit nod, suggests that attention alone isn’t enough — memecoins need sustained community traction or utility memes to drive value.
- It also hints that retail appetite may be cooling, especially as memecoins become more saturated and short-term rotations grow more competitive.
Derivatives Positioning
- Monero’s (XMR) perpetual futures market looks overheated, with annualized funding rates nearing the 100% mark. Extreme bullish positioning often translates into sudden price pull backs.
- BCH and SUI markets face the opposite situation with bias for shorts driving funding rates to minus 20% or lower. This could potentially lead to a short squeeze and a big move higher.
- BTC futures open interest on the CME rose to $14.01 billion on Friday, the highest since Feb. 21. ETH open interest remains flat near recent lows under $1.5 billion.
- On Deribit, BTC calls trade at a premium to puts across multiple time frames, risk reversals show. In ETH’s case, bullishness is seen only after the end-May expiry.
