Cetus Protocol Restarts After $223M Exploit, but Tens of Millions Remain Missing

Sui's largest DEX, Cetus Protocol, resumed operations this week after an attacker drained $223 million through an integer overflow flaw in its fixed-point math library. The exploit took just 15 minutes. Sui validators froze $162 million on-chain before the attacker could bridge it out, and those funds have been returned. Cetus plugged the remaining gap with $7 million of its own reserves plus a $30 million USDC loan from the Sui Foundation. The attacker still controls roughly $60 million bridged to Ethereum, some of which is already flowing through Tornado Cash. The incident sparked debate over validator-level censorship: Sui's ability to freeze funds fast arguably saved users, but the precedent concerns DeFi purists. Source: The Block, Cyfrin, DL News.

Solana ETF Inflows Cross $1.1 Billion as Morgan Stanley Files Staking-Enabled Fund

Spot Solana ETFs have now pulled in $1.12 billion in cumulative inflows, with Bitwise's BSOL fund accounting for roughly $861 million of that total. Meanwhile, Morgan Stanley filed an amended registration for its own SOL ETF (ticker: MSOL) on NYSE Arca, with a key detail: the trust may stake up to 100% of its holdings through third-party providers. If approved, it would be the first major bank-branded crypto ETF with native staking built in. Ethereum ETFs, by contrast, saw $104 million in net outflows during the same period.

Trump Signs Executive Order Opening Fed Payment Rails to Crypto Firms

President Trump signed an executive order on May 19 directing the Federal Reserve to conduct a 120-day review of whether crypto and fintech companies should get direct access to Reserve Bank payment services. The order, titled "Integrating Financial Technology Innovation into Regulatory Frameworks," follows the Fed's earlier decision to grant Kraken (a Wyoming SPDI) limited master account access. If regulators follow through, stablecoin issuers and crypto custodians could settle transactions directly through the Fed rather than relying on bank intermediaries. Consumer advocacy groups have pushed back, calling it a deregulation risk. Source: CoinDesk, White House Fact Sheet, Bitcoin Magazine.

Coinbase Launches USDF Stablecoin on Solana via Flipcash

Coinbase's new Custom Stablecoin platform scored its first client: Flipcash, a community currency app that went live on Solana with USDF, a branded stablecoin fully backed 1:1 by USDC. USDF serves as the settlement layer for Flipcash's ecosystem, where users create fixed-supply community currencies. The model positions Coinbase as a white-label stablecoin infrastructure provider, a growing market as more companies look to issue branded digital dollars without building their own reserve management.

Ethereum's Glamsterdam Upgrade Triples Gas Capacity

The Glamsterdam hard fork, which went live on May 1, raised Ethereum's gas limit to 200 million, effectively tripling the network's throughput. Early data shows mainnet fees dropping, reinforcing the trend of L1 as settlement layer while L2s handle execution. Staking participation continues to climb: over 34 million ETH (28% of supply) is now locked, generating 3.5-4.5% annualized. BlackRock's staked ETH ETF pulled $100 million on its first trading day, and exchange-held ETH has fallen to a yearly low of 14.9 million. Source: Ethereum Foundation, Blockworks, AInvest.

2026 Hack Tally Passes $450 Million Across 45 Protocols

The Cetus exploit pushes 2026's total DeFi losses past $450 million across roughly 45 protocols. The year's largest incident remains the KelpDAO bridge exploit in April ($294 million). A pattern is emerging: bridge contracts and cross-chain math libraries remain the weakest links. Individual-targeted attacks (phishing, social engineering of high-net-worth holders) have also surged, with some of the biggest Q1 losses coming from compromised individual wallets rather than protocol code.
