BNB Chain’s Good Will Alliance Fights MEV Attacks for Fairer Trading

BNB Chain has taken a bold step in protecting its users by launching the Good Will Alliance, a dedicated initiative to combat malicious Miner Extractable Value MEV practices, specifically sandwich attacks

With increasing concerns over unfair trading practices on decentralized exchanges, this move aims to ensure transparency and security for all participants on Binance Smart Chain BSC

Understanding Sandwich Attacks in Crypto

A sandwich attack is a type of front running tactic used by bad actors to exploit regular traders on decentralized exchanges DEXs

How it Works

1. Step One A malicious actor detects a pending buy order from a trader
2. Step Two The attacker places a buy order before the trader’s order, driving up the asset’s price
3. Step Three The trader’s order gets executed at an inflated price
4. Step Four The attacker then sells their assets at a higher price, profiting at the trader’s expense

This tactic harms everyday traders by manipulating transaction costs and making trades more expensive

Key Initiatives by the Good Will Alliance

BNB Chain has introduced several measures to stop sandwich attacks and improve transaction security

1. Deployment of Sandwich Attack Filters

Key infrastructure providers such as BlockRazor and 48 Club have integrated specialized filters into their block building processes to detect and block sandwich attacks. These filters enhance security by preventing exploitative trades before they happen

2. Validator Participation and MEV Compliant Builders

The Good Will Alliance has created a GitHub repository listing MEV compliant block builders. BSC validators are encouraged to accept block bids only from these vetted participants to maintain fair trading conditions and ethical network standards

3. Community Collaboration and Governance Support

The initiative has received significant backing from the BNB Chain community. In February 2025, a proposal to support the Good Will Alliance passed with 79 percent approval in the BNB Chain DAO. This highlights strong community interest in penalizing malicious builders and promoting MEV protected wallets and safer Remote Procedure Call RPC nodes

What’s Next for the Good Will Alliance

BNB Chain plans to expand the Good Will Alliance with additional security measures

• Development of Advanced Tools to detect and prevent various MEV related frauds
• Promotion of Ethical Standards within the BNB ecosystem to encourage fair trading practices
• Stronger Validator and Developer Collaborations to build infrastructure that prevents sandwich attacks

Final Thoughts A More Secure Future for BNB Chain

The Good Will Alliance marks a major step forward in making Binance Smart Chain a safer, fairer trading environment. By involving validators, developers, and the community, BNB Chain is setting a new standard for transparency in crypto trading

With ongoing developments in MEV protection, the alliance could serve as a blueprint for other blockchain networks looking to enhance security

• Will initiatives like the Good Will Alliance be enough to stop MEV attacks?
