The BNB Chain has recently launched the Good Will Alliance, a collaborative effort aimed at combating malicious maximal extractable value (MEV) practices, starting with targeted measures against sandwich attacks. The initiative aims to bring together infrastructure builders, validators, and the broader community to establish ethical standards, best practices, and enhanced security within the BNB ecosystem. Sandwich attacks, a prevalent form of malicious MEV, have caused significant losses to retail traders on Binance Smart Chain (BSC), totaling hundreds of millions of dollars according to BNBChain DAO.
In response to these challenges, the alliance’s initial action focuses on mitigating sandwich attacks through advanced filtering mechanisms. Infrastructure providers BlockRazor and 48 Club have deployed specialized sandwich attack filters within their block-building processes, setting an early benchmark for alliance participants. The alliance has also established a GitHub repository listing builders compliant with ethical standards, urging BSC validators to exclusively accept block bids from this vetted group. The alliance’s strategy involves defining clearer criteria for identifying sandwich attacks, developing sophisticated tooling to detect malicious MEV behavior, and fostering deeper community collaboration to enhance on-chain security.
The Good Will Alliance’s efforts will continue to evolve through governance processes, BNB Evolution Proposals (BEPs), and regular codebase updates with the goal of achieving long-term improvements in network fairness. The initiative has garnered strong community support, as evidenced by a DAO proposal that passed with 79% approval on February 14. The proposal emphasizes the importance of community-driven measures, including penalties for malicious builders, exclusion of irresponsible validators, and adoption of safer RPC nodes and MEV-protected wallets.
Looking ahead, the Good Will Alliance plans to expand its scope by actively seeking additional members to introduce further community-oriented security projects throughout 2025. By bringing together key stakeholders within the BNB ecosystem and implementing proactive measures against malicious MEV practices, the alliance aims to create a safer and more secure environment for all participants. Through collaboration, innovation, and a commitment to ethical standards, the alliance is poised to make a meaningful impact in shaping the future of BNB Chain’s network security and integrity.
