PANews reported on May 29th that, according to the Arbitrum forum, the Arbitrum Security Committee urgently implemented a protocol upgrade on May 24th to fix a governance vulnerability in the L1 Timelock contract. This vulnerability could have allowed attackers to revoke the PROPOSER_ROLE permission on the Arbitrum Bridge via cross-chain messages, thereby preventing the execution of future constitutional governance proposals. However, the official statement emphasized that user funds have never been at risk, and that the Security Committee can intervene to prevent attacks within a 7-day fraud proof window.

In addition, the Arbitrum Foundation has launched a new funding proposal, seeking $16 million in stablecoins/RWA, 1,740 ETH, and 230 million ARB from the DAO to support operations, technical maintenance, ecosystem incentives, and strategic partnerships in 2027. The Foundation projects operating expenses of approximately $27.6 million in 2027, with technology-related costs accounting for 54%, and plans to continue promoting ecosystem growth in areas such as Timeboost, RWA, AI, and institutional asset tokenization. The proposal is currently under community discussion and a temperature check vote.
