Today in crypto featured continued institutional inflows into Bitcoin, major custodial expansion into altcoins, a security warning for the Bitcoin Lightning Network, and several notable token and treasury moves across DeFi firms and projects.
Bitcoin ETFs keep drawing money
US spot Bitcoin ETFs extended a multi-session inflow streak, taking in $2.8 billion over eight sessions while Bitcoin reached $80,475. BlackRock’s IBIT accounted for 72% of that flow. Combined flows into gold and Bitcoin ETFs reached $7 billion over a five-day period, a record for that span.
Charles Schwab adds Solana, Avalanche and Chainlink
Charles Schwab will expand the set of tokens available on its crypto trading platform to include Solana (SOL), Avalanche (AVAX) and Chainlink (LINK), in addition to Bitcoin and Ethereum. The brokerage launched the service in May with a 0.75% commission per trade. Schwab is a large custodial firm managing $13.04 trillion in client assets.
Core Lightning developers issue urgent security warning
Developers of Core Lightning warned that vulnerabilities identified by artificial intelligence tools are real and urged users to install the upcoming update immediately. For those unable to upgrade right away, the advice was to go offline rather than simply shutting down. The Bitcoin Red Team has recorded 4,962 potential findings across 390 projects, underlining ongoing scrutiny of crypto software.
First quantum-resistant Bitcoin mainnet transaction completed
A researcher at StarkWare completed what was described as the first quantum-resistant Bitcoin transaction on mainnet at block 964,199 without changing consensus rules. The method, termed Quantum Safe Bitcoin, uses signature “grinding” instead of the usual elliptic curve approach. The transaction reportedly cost a few hundred dollars and currently works only with older pre-SegWit addresses.
Hyperliquid’s PURR vault and HYPE holdings grow
Hyperliquid Strategies’ PURR product raised $647 million and more than doubled its HYPE vault to 29.3 million tokens, valued at $1.9 billion. The firm bought an additional 16.5 million HYPE for $773.4 million. The related stock rose nearly 18% following the activity.
DeFi Development Corp increases Solana holdings
DeFi Development Corp (DFDV) purchased roughly 19,000 SOL at an average price of $98.14, bringing its total holdings to 2.33 million SOL. The acquisition was partly funded by the sale of a subsidiary, and DFDV’s stock rose 12% after the announcement.
Ethena Foundation updates token policy and buyback plan
The Ethena Foundation announced redemption of locked ENA held by early investors and said monthly unlocks will end starting October 5. It proposed a “fee switch” that would direct 95% of certain proceeds into ENA buybacks once the USDe supply reaches a specified milestone. The plan leaves about 12% of ENA supply remaining locked.
Taken together, the day’s headlines reflect continued institutional capital flows into Bitcoin and product expansion by custodial platforms, alongside active risk management and treasury decisions in tokenised projects. At the same time, the Lightning Network warning and a first-of-its-kind quantum-resistant mainnet transaction highlight the coexistence of security concerns and technical experimentation across the ecosystem.
