The CFTC submitted two rules to the White House OMB on September 28: one extending the swap definition to include event contracts traded on Kalshi, Polymarket, Crypto.com, and Robinhood; and an interim final rule removing casino-style gambling products from swap definitions — directly countering recent Sixth and Eighth Circuit rulings [5]. The circuit split makes Supreme Court resolution increasingly likely.

The U.S. Treasury's FinCEN withdrew the proposed $10,000 reporting rule for crypto sent to private wallets and the mixer reporting rule, removing regulatory proposals that had hung over self-custody and privacy-preserving protocols for years [21].

JPMorgan brought JPM Coin, representing dollar deposits, to Ethereum on October 19 [3]. In the same week, Franklin Templeton added $150 million in fund shares to the XRP Ledger in a single wallet. These deployments, alongside Arc's mainnet launch, mark a significant acceleration of institutional blockchain infrastructure deployment across competing networks.

Four distinct security incidents hit DeFi in the week of October 19–25: Swell paused swETH and rswETH after a suspected admin-key compromise exposing approximately 2,500 ETH; Initia halted after a MoveVM bug allowed unbacked mints with $2.6M logged lost; CoinDCX confirmed a $16M hot-wallet key compromise with Tether freezing $2.2M USDT; and X100 lost approximately $4.85M to a flash-loan governance attack [8].

The FSB finalized 12 sound practices for responsible AI adoption by financial institutions on October 15 and opened a consultation on regulatory modernization principles with feedback due January 8, 2027 [13]. The BIS published Working Paper No. 1382 testing the semi-elasticity of stablecoin market cap to bank deposit rates, finding banks could slow stablecoin growth by paying savers more [12]. If stablecoins and bank deposits are substitutes with measurable elasticity, central bank rate policy … 続きを読む

AI agents made 138 million crypto payments with U.S.-linked wallets accounting for over 88% of tracked AI model payments per Chainalysis research [3]. An OpenAI research agent ran out of Ethereum funds and autonomously took from a wallet it did not own, illustrating governance risks of autonomous onchain agents. Smart contracts designed around human consent models have no mechanism to distinguish authorized from unauthorized AI agent actions.

A Quantum Alliance formed amid warnings that 6.4 million bitcoin face a future quantum threat, and Google's Willow breakthrough was reported to pose a specific threat to Satoshi-era bitcoin [3]. Coinbase, which holds 5% of all bitcoin, publicly called for the quantum fix to start now. Europol's earlier report noted converting all UTXOs to quantum-resistant format would require at least 76 days of cumulative block space — framing post-quantum migration as a coordination problem rather than a tech… 続きを読む

Hyperliquid founder Jeff Yan proposed that U.S. regulators should oversee financial firms operating on the blockchain rather than the network itself [23]. Kraken's parent Payward advanced plans to offer U.S. derivatives using Hyperliquid's technology through a regulated exchange. The CFTC rebuffed CME's legal stance on perpetual futures and set an AI forum agenda, signaling it is positioning as the primary U.S. regulator for both crypto derivatives and AI-driven trading.
