first_img Arbitrum Security Committee urgently suspended the activation of the new contract Stylus and added BoLD protection

On October 2, at 11:30 AM Eastern Time, the Arbitrum Security Committee executed an emergency upgrade on Arbitrum One and Nova, suspending the activation of all new Stylus contracts on both chains, while adding a protective mechanism against BoLD single-step proofs in the dispute system of Arbitrum One. The Arbitrum Foundation stated that this action is part of ongoing proactive security measures aimed at protecting the security and integrity of the network.Stylus allows developers to write smart contracts using languages such as Rust and C++, while maintaining compatibility with the Ethereum Virtual Machine, with its programs compiled into WebAssembly format. This suspension primarily targets manually written WASM programs that do not use the standard Stylus compiler toolchain and have not yet been patched by the current version of ArbOS. The Security Committee increased the gas required for activation to the theoretical maximum by calling ArbOwner.setWasmActivationGas(2^64 - 1), making new activations economically unfeasible. Activated Stylus contracts are unaffected and can continue to execute and renew, and the deployment and execution of Solidity contracts are also unrestricted.The newly added BoLD protection allows anyone to pause the settlement from Arbitrum One to Ethereum when two conflicting and accepted answers appear in the same dispute step, which may delay unconfirmed withdrawals to allow the Security Committee to deploy fixes. Officials pointed out that the currently discovered Stylus-related vulnerabilities mainly affect the activity of the chain, such as denial-of-service attacks, and do not jeopardize user funds.

first_img The Bank of America group sued the OCC, accusing it of overstepping its authority by issuing trust licenses to cryptocurrency companies

The Independent Community Bankers of America (ICBA) filed a lawsuit against the Office of the Comptroller of the Currency (OCC) in federal court on Friday, accusing it of exceeding its statutory authority when issuing national trust bank charters to cryptocurrency companies. The ICBA stated that the OCC is implementing "broad new powers not authorized by the National Bank Act," allowing these companies to enter the U.S. banking system without being subject to the same level of regulatory oversight as community banks, putting small banks at a "serious competitive disadvantage."The ICBA is one of the largest banking advocacy organizations in the United States, primarily representing small institutions. Last month, the organization strongly opposed the Digital Asset Market Structure Bill, which failed to advance in the U.S. Senate, arguing that its stablecoin provisions did not protect community banks from direct competition for deposit accounts. ICBA President and CEO Rebeca Romero Rainey stated that Congress did not establish the national trust charter to provide a "backdoor" for cryptocurrency companies seeking to enter the banking system with the credibility of a federal bank charter, as these companies do not bear the same obligations regarding capital, liquidity, regulation, and Federal Deposit Insurance Corporation (FDIC) insurance requirements. An OCC spokesperson responded to CoinDesk that the agency does not comment on ongoing litigation.Recently, the OCC has continued to issue trust charters to cryptocurrency companies, but these companies' business models differ from those of typical community banks and do not offer cash deposit accounts that require FDIC insurance. Approved institutions include cryptocurrency banks Protego and Erebor, as well as existing cryptocurrency firms like Coinbase, Circle, and Crypto.com.
