Ethereum Delays Glamsterdam Over Smart Contract Security Risks

Ethereum developers pulled the emergency brake on Glamsterdam. The network's next major upgrade was set to activate on the Hoodi testnet Monday, but security researchers at ChainSecurity identified 13 real-world smart contracts that could be broken by the fork's proposed gas repricing. The testnet launch is now indefinitely delayed while teams coordinate responsible disclosure with affected projects.

ETH traded at $2,395.68, down 0.33% over 24 hours, with a market cap of $292.6 billion and $11.7 billion in daily volume.

Glamsterdam's Gas Problem

The specific concern centers on how new gas rules would interact with existing smart contracts. ChainSecurity's analysis showed that the repricing could cause certain contracts to permanently record failed operations, a behavior that doesn't exist under current rules. The distinction matters: temporary failures that revert cleanly are a normal part of contract execution, but permanent failure logging could corrupt state and create unpredictable downstream effects.

Ethereum core developers canceled the Hoodi activation outright rather than pushing ahead with known risks. The decision reflects a shift in upgrade philosophy that has taken hold since the Pectra rollout: ship slower, break nothing. No new target date has been announced. The timing is unclear, and the scope of required contract-level fixes across affected protocols could stretch the delay by weeks.

HSBC Brings a Stablecoin to 3 Million Users

HSBC began rolling out RedCoin wallets to PayMe users in Hong Kong, making it one of the largest traditional banks to put a stablecoin directly into a consumer payments app. The Hong Kong dollar-pegged stablecoin, HKDAP, was developed through Anchorpoint, a joint venture between HSBC and Standard Chartered that received one of Hong Kong's first stablecoin issuer licenses in April.

RedCoin wallets will initially support retail payments, with plans to add tokenized investment subscriptions and institutional settlement. The rollout puts a stablecoin in the hands of over 3 million everyday banking customers, a distribution channel that dwarfs most crypto-native stablecoin launches.

The move adds pressure on stablecoin issuers like Circle and Tether, which have built dominance through crypto-native channels. When a bank with HSBC's scale embeds a stablecoin directly into an app people already use for groceries and rent, the competitive dynamics shift.

Stablecoin Regulation Picks Up Across Asia

HSBC's launch sits within a broader Asian regulatory push. South Korea is amending its foreign exchange law to classify stablecoins as payment instruments, folding them into the Digital Asset Basic Act currently under development. Separately, Malaysia and Thailand joined Singapore's BLOOM initiative, a cross-border stablecoin framework designed to reduce settlement costs by coordinating how financial institutions use stablecoins and tokenized deposits across jurisdictions.

Sweden's Riksbank, meanwhile, revived the e-krona debate, framing a central bank digital currency as essential to maintaining monetary sovereignty as private stablecoins and the digital euro gain traction. The pattern is consistent: governments that initially watched stablecoins with curiosity are now racing to regulate or compete with them.

Bitcoin ETFs Shed $635 Million

U.S. spot Bitcoin ETFs recorded $635 million in outflows on Thursday, ending a three-day inflow streak and pushing October's net flows back into the red at negative $175 million. Bitcoin itself held relatively steady at $81,700, up 0.5% since midnight UTC.

The CoinDesk 80 index gained 1.4%, with memecoins outperforming at 2.9%. Bitcoin's price stability amid heavy ETF selling suggests other buyers are absorbing the supply, though the ETF flow reversal dampens the narrative of sustained institutional accumulation that had been building earlier in the month.

Polymarket Fires Marketing Chief

Polymarket ousted its marketing chief Matthew Modabber, a close friend of CEO Shayne Coplan, following an internal investigation into multiple instances of misconduct, the New York Post reported. The prediction market platform has been under heightened scrutiny as it scales beyond crypto-native users, and internal governance failures at this stage carry reputational cost.

Security Blotter

An attacker exploited Cysic's cross-chain bridge to mint 10 million tokens on BNB Smart Chain, then moved $744,000 in ETH and BNB through Tornado Cash. Cysic offered a 10% bounty. The hacker declined by action.

India's CoinDCX denied a hack after on-chain investigators flagged $16 million in suspicious outflows from addresses linked to the exchange. The company said its active wallets were not compromised, though it has not publicly explained the flagged transactions.

Bitcoin Core updated its security disclosure policy, acknowledging that AI-assisted bug hunting has made it impractical to keep certain vulnerability details secret for extended periods. The project will now disclose more bugs faster.

Magic City Update

The Glamsterdam delay carries specific implications for Miami's Ethereum builder community. Several Miami-based teams building on Ethereum mainnet, particularly in the DeFi and real estate tokenization verticals where gas optimization is a constant concern, will need to audit their contracts against ChainSecurity's findings once full details are published. Securitize, which has built much of its tokenized securities infrastructure on Ethereum and maintains a significant Miami presence, is the kind of issuer that should be watching gas repricing proposals closely, given that even small execution cost changes can affect the economics of on-chain settlement for tokenized assets.

For Miami developers building with tools from Alchemy or deploying on L2s like Arbitrum, the delay is a reminder that mainnet upgrade timelines remain unpredictable. Teams relying on Glamsterdam features for upcoming product launches should build contingency into their roadmaps.

On the events front, Miami's positioning as a stablecoin hub gets a narrative boost from the HSBC and Asian regulatory developments. The city has attracted stablecoin infrastructure companies like Paxos and Zero Hash, both of which have operations in the Miami metro area. As stablecoin regulation crystallizes globally, Miami's concentration of compliance-aware crypto firms puts it at the center of the conversation about how these instruments will be governed in the U.S.
