Ethereum Foundation Ships zkAPI as Bitcoin Dominance Eyes 60% | ethereum.miami
ETH traded at $2,743.28, up 1.58% over 24 hours, against a backdrop of rising risk appetite across crypto markets. Bitcoin dominance is pushing toward 60% for the first time since late 2025, while Tether's USDT dominance has slipped to 6.3%. The dynamic signals capital rotating out of stablecoins and into spot positions. Ether ETF flows remain a sore point: a third consecutive day of net outflows, even as Bitcoin ETFs kicked off October with $103 million in inflows.
Ethereum Foundation Launches zkAPI for Private AI Payments
The Ethereum Foundation released zkAPI, a system that lets users pay for AI model access without revealing their identity. The mechanism is straightforward: users deposit funds into an Ethereum vault, then authorize spending through zero-knowledge proofs. The API provider verifies payment without ever linking a request to a specific wallet or payer.
The release sits at a growing intersection between Ethereum infrastructure and AI compute markets. As demand for inference API access scales, the ability to pay without creating a surveillance trail becomes a meaningful feature, not a novelty. Whether zkAPI sees adoption beyond privacy-focused users depends on how AI providers choose to integrate it, but the plumbing is now public.
Aave V3 Untouched After $305K Adapter Exploit
An attacker drained roughly $305,000 from two Safe multisig wallets by exploiting a third-party adapter, not Aave's core protocol. Aave founder Stani Kulechov confirmed that Aave V3 itself was unaffected. The distinction matters: the vulnerability lived in peripheral tooling connecting Safe wallets to DeFi protocols, not in the lending contracts that hold billions in deposits.
The incident is small in dollar terms but underscores a persistent risk in composable DeFi. The attack surface isn't always the protocol. It's often the connective tissue between protocols, the adapters, bridges, and wrappers that users rely on without scrutinizing.
Bitcoin's October Momentum Builds
Bitcoin pushed toward $87,800 on October 1, triggering over $120 million in short liquidations. Open interest jumped $2.3 billion as funding rates climbed, reflecting renewed demand for leveraged long positions. The move came ahead of the U.S. September jobs report, with traders positioning for macro data that could shape Federal Reserve expectations.
Spot Bitcoin ETFs recorded $2.65 billion in net inflows for September, their second-largest monthly haul since October 2025. The institutional bid remains intact even as ether funds bleed. Arthur Hayes, speaking at CONNECT Seoul, pointed to monetary expansion as the structural tailwind: more money printing means higher crypto prices, in his framing.
Robinhood Flags Constraints in SEC Tokenized Stock Framework
Robinhood crypto chief Johann Kerbrat said the SEC's innovation exemption for tokenized equities presents practical constraints the company is still working through. The exemption framework, designed to let firms experiment with stock tokens under a regulatory sandbox, apparently creates enough friction that a major retail brokerage hasn't yet committed to a launch timeline.
The comments land as South Korea's Financial Services Commission proposed its own detailed rules for tokenized securities, including capital requirements for issuers, OTC trading licenses, and retail investment caps, all ahead of a planned 2027 rollout. Two jurisdictions, two approaches. South Korea is writing prescriptive rules. The SEC is offering limited exemptions. Neither path is fast.
ECB Sketches Onchain Settlement Models
The European Central Bank outlined three models for putting central bank money onchain, a step toward integrating traditional settlement infrastructure with blockchain rails. The details remain at the conceptual stage, but the signal is clear: European regulators are actively designing how sovereign money coexists with tokenized assets, not debating whether it should.
The ECB's work parallels Wall Street's own onchain ambitions. At CONNECT Seoul, speakers examined how traditional finance firms are building competitive advantages on blockchain infrastructure, a theme that keeps gaining weight as JPMorgan, BlackRock, and others deepen their commitments.
Tether Returns USDT to Bitcoin
Tether announced that USDT is returning to Bitcoin, the chain where it originally launched over a decade ago. A Tether-backed project called Utexo will support private USDT transfers, direct BTC-to-USDT swaps, and Bitcoin-collateralized loans, all while keeping most transaction data off the public ledger.
The move represents a full-circle moment. USDT began on Bitcoin's Omni Layer before migrating primarily to Ethereum and Tron. Bringing it back with privacy features and lending capabilities suggests Tether sees Bitcoin as more than a settlement layer. Whether users migrate meaningful volume to this implementation is another question.
South Korean Exchanges Feel the Squeeze
Operating profits at South Korean crypto exchanges fell 78% in the first half of 2026 as trading volumes, market capitalization, and customer deposits all declined. The country's exchange market, dominated by Upbit, has been under pressure from tightening regulations and a broader cooldown in retail speculation.
The profit collapse coincides with Seoul's push to formalize tokenized securities rules, suggesting regulators are reshaping the market's structure even as current business models contract.
Porsche Pulls the Plug on Web3
Porsche is shutting down its Web3 project and Pioneers Circle community after fewer than four years. Trading activity in its 911 NFT collection has fallen sharply from early levels. The automaker described the effort as a "long haul" at launch. It was not.
The exit adds to a growing list of corporate NFT projects that underestimated how difficult sustained community engagement is when the speculative premium evaporates. Porsche joins a cohort of brands that treated Web3 as a marketing experiment and found the experiment expensive.
Security Notes
Core Lightning issued an urgent advisory telling node operators running version 26.06.7 or earlier to upgrade immediately, citing active attacks against unpatched nodes. Separately, the Zano blockchain rolled back after an exploiter minted more than a quadrillion fUSD tokens that were indistinguishable from legitimate coins. Spanish police arrested a 16-year-old accused of running the KillSec ransomware group, which demanded payment in crypto.
Miami Builds the Tokenization Pipeline
As South Korea and the SEC independently wrestle with tokenized securities frameworks, Miami continues positioning itself as the U.S. city where that infrastructure actually gets built. Securitize, headquartered in the Miami metro area, remains one of the primary platforms through which real-world asset tokenization reaches institutional investors. The company's work with BlackRock's BUIDL fund and other tokenized products gives Miami a direct stake in the regulatory outcomes now being negotiated in Washington and Seoul.
Homebase, another Miami-based platform focused on tokenized real estate, operates at the retail end of the same pipeline. While regulators debate capital requirements and investor limits for tokenized securities, Homebase has been processing fractional real estate investments on Ethereum for existing customers. Miami's real estate market, one of the most active in the country, provides a natural testing ground for these products.
The Ethereum Foundation's zkAPI launch also has local resonance. Miami's growing AI and crypto startup scene creates a natural user base for privacy-preserving payment infrastructure. Several Miami-based Web3 companies have been building at the intersection of AI inference and blockchain payments, exactly the use case zkAPI targets.
