$GRVT The Arbitrum Security Council completed an emergency action on Oct. 2 that temporarily disables new Stylus contract activations on Arbitrum One and Nova. The council raised the activation gas requirement to 264−1, effectively making new activations infeasible, according to an Arbitrum Foundation Forum post published at 3:30 p.m. ET. Arbitrum described the measure as a precaution against sophisticated attacks using hand-crafted WebAssembly programs. It said the potential attacks may be AI-assisted and could degrade chain performance or create denial-of-service conditions; the network reported no known theft of user funds. Emergency gas threshold halts new Stylus activations The emergency change does not remove Stylus from the network, but it blocks several paths requiring a fresh activation. Those include new Stylus contracts, reactivation of expired contracts and application updates that require activation. Stylus is Arbitrum’s environment for deploying programs that can use WebAssembly-based languages alongside Ethereum-compatible smart contracts. By setting the activation requirement at the maximum stated threshold, the council has temporarily stopped developers from bringing those new or updated Stylus applications into operation. The forum notice did not provide a date for restoring normal activation conditions or describe a separate governance timetable for the change. Hand-crafted WebAssembly prompted the precautionary pause Arbitrum said its concern centers on specially constructed, hand-crafted WebAssembly programs, not a confirmed exploit involving user assets or known user-fund theft. In the network’s assessment, such programs could strain chain performance or trigger a denial-of-service scenario. The precautionary action is intended to prevent potentially risky new Stylus code from being activated while leaving already-active contracts and existing operations in place, rather than shutting down Stylus activity generally. Active contracts and EVM deployments remain operational Already-active Stylus contracts continue to operate under the emergency action. Solidity and other EVM deployment and execution are also unaffected, Arbitrum said, limiting the direct restriction to the Stylus activation process. Separately, the action added a permissionless guard for Arbitrum One’s BoLD one-step proof system. The safeguard allows settlement to Ethereum to be paused if conflicting proofs are accepted, according to Crypto Briefing. That additional measure addresses the settlement path rather than the activation restriction itself, adding a mechanism to halt settlement in the specified conflicting-proof scenario.

$GRVT Bitcoin treasury accumulation is still moving higher, with four companies adding a combined 3,342 BTC, which are nearly worth $286.31 million, during the week from September 28 to October 4th. The bigger story though, is where liquidity is moving while corporate balance sheets keep absorbing supply. Public Treasuries Keep Adding Despite Market Rotation Michael Saylor’s Strategy has added a stash of 334 BTC, taking its holdings to 848,000BTC. Strive Asset Management made the largest purchase  this week at 2,000 BTC, lifting its reserves to 29,462 BTC, when writing. The two more firms added, one is Metaplanet that has added 1,000 BTC bringing a cumulative count to 44,000 BTC, while Remixpoint added 8 BTC to reach 1,509 BTC’s. Together, the tracked public treasuries now hold 922,971 BTC in total which are valued to $79.07 billion from current exchange price of BTC. That’s a sizable concentration of corporate exposure that has been witnessed this week, per the data from LookOnChain on X. Stablecoin Capital Is Leaving Ethereum Mainnet Meanwhile, stablecoin liquidity is telling a different story. As the data suggests, the Global net stablecoin supply has expanded by $715.8 million, yet Ethereum recorded $974 million in net outflows. But, Solana absorbed $371 million, while Tron took in $215 million. Base added $70.6 million, followed by Arc at $54.2 million and Arbitrum at $41.7 million. The observation shows that rotation doesn’t exactly scream broad-based risk appetite. DEX Volumes Slide While Perps Stay Dominant Moreover, the data indicates further details like the DEX spot volume has taken a toll as it fell 3.92% week over week to $59.24 billion, while perpetual volume fell 9.85% to $138.12 billion. Hyperliquid remained the largest decentralized perpetual venue with $41.53 billion despite a 24.31% decline. Variational, Lighter and Aster also posted weekly contractions. GMX was the obvious outlier, surging 243.76% to $8.22 billion. For now, Bitcoin treasury accumulation remains strong even as stablecoin capital rotates across chains and decentralized derivatives activity loses momentum.
