Stories clustered across sources, with day-to-day continuity and threading.
The Rules Arrive Without the Lock
Following the CLARITY Act's defeat, SEC Chair Paul Atkins signalled the agency will pursue crypto regulatory clarity with or without legislation, and the CFTC chairman affirmed the agency will write crypto rules independently, per Bitcoin Magazine and multiple outlets. Bernstein projected swift SEC and CFTC rulemaking and noted stablecoin rewards on idle balances continue unaddressed by statute, per The Block. Coverage flagged that agency guidance lacks a statute's durability and can be reversed by a future administration.
Hyperliquid Gets a Guest List
Payward, Kraken's parent, announced plans to offer US clients on-chain perpetual futures through Hyperliquid, using what coverage described as HIP-3* markets — a permissioned variant allowing market operators to restrict participation — with Bitnomial building the contracts and NinjaTrader carrying accounts, per CoinDesk and multiple outlets. The offering was reported as planned rather than live. Coverage framed it as a test model for regulated US DeFi access.
Two Robinhood Engineers Charged With Insider Trading Using Hyperliquid Perpetuals
The US Department of Justice charged two Robinhood engineers with insider trading, alleging they opened perpetual futures positions on Hyperliquid ahead of token listings on their own platform, per CoinDesk. The pair face up to 30 years in prison over approximately $50,000 in alleged profits, per coverage. Outlets framed the case as the first federal prosecution centred on front-running via on-chain perpetuals.
Circle's Arc Mainnet Goes Live
Circle launched its Arc blockchain mainnet with BlackRock and Visa among eleven permissioned validators, minting 10 billion ARC tokens and making USDC the network's gas token, per The Block and The Information. Contract deployment is permissionless while validation remains restricted to the named institutions. Day-one support included Binance USDC deposits, Robinhood integration and Circle's x402 payments service, per coverage. The DTCC's leg — tokenising DTC-custodied assets on Arc — is slated for H2 2027.
