The Binance Smart Chain (BSC) ecosystem has recently experienced a series of scams and numerous hacking incidents. Due to the decentralized and permissionless nature of the BSC blockchain, addressing these challenges is complex. The ecosystem currently faces several critical issues:
- The rapid growth of BSC has made it a prime target for organized hacker groups. These actors continuously search for potential vulnerabilities in various protocols and may have discovered more zero-day exploits (vulnerabilities known to attackers but not yet patched).
- Some projects within the ecosystem lack experience in secure software development and risk management. Common shortcomings include insufficient code audits, penetration testing, and collaboration with security professionals.
This is a significant challenge. Only secure blockchains can achieve long-term success. For Binance Smart Chain, safety is the top priority—a principle embedded in every action taken. This article explores common threats and answers pressing questions about BSC security.
What Threats Does BSC Face?
The threats targeting BSC are similar to those affecting most crypto-asset ecosystems. In many ways, BSC's situation parallels the Ethereum boom of 2017. Hundreds of projects with millions of users have joined the blockchain, attracting hackers and scammers.
The crypto community has faced social engineering scams, hacking, personal data leaks, fake projects, and Ponzi schemes. While attackers have gained years of experience, their methods have not changed drastically.
Threats generally fall into two categories:
External Threats – These originate from outside a project. External attackers typically exploit technical or operational weaknesses through hacking or social engineering attacks. Their goals include stealing funds, obtaining valuable information, or causing project failures.
Internal Threats – These include notorious exit scams, rug pulls, and insider leaks. Internal threats are harder to defend against and often involve complex investigations. In most cases, they result from individual team members abusing power for personal gain, though organized group attacks also occur.
Is Binance Smart Chain Secure?
The question of whether Binance Smart Chain—or any blockchain—is secure can be addressed from multiple angles. One aspect is the security of the code, nodes, and the blockchain itself. Another is the safety of the broader ecosystem.
The BSC ecosystem comprises various components and participants, each facing distinct threats. These include code, algorithms, validator nodes and their hardware, projects built on BSC, and individual users.
The decentralized BSC blockchain runs on open-source code, auditable by third parties and the public. With open-source code, anyone with technical expertise can review it to assess potential vulnerabilities. The Proof of Staked Authority (PoSA) algorithm relies on 21 elected validator nodes, preventing any single node from gaining excessive control or abusing power.
The BSC network and its algorithm are inherently secure. The fact that BSC itself has not experienced security breaches or hacking events indicates no systemic vulnerabilities or attack vectors exist. Additionally, BSC incentivizes security teams and projects to conduct regular reviews through its bounty programs, ensuring even minor issues are promptly addressed.
Are dApps on BSC Secure?
While the BSC network and its code can be verified and audited, the same is not always true for individual projects. Not every BSC project is open-source, and open-source does not automatically mean secure. Smart contract security is also a concern, as no code is entirely free of defects. Since each project is developed by an independent team, the potential for vulnerabilities always exists.
Due to BSC’s decentralized nature, almost anyone can develop on the network and list tokens on decentralized exchanges. Many projects bypass centralized review processes or governance because imposing such checks would undermine decentralization and is technically impractical.
Security firms like PeckShield and CertiK audit and verify various BSC tokens and dApps. Their meticulous security reviews can identify potential flaws in code, business models, and other areas. These audits often include verifying the core team's credentials and examining the project’s financial health. However, these audits are not mandatory and are rarely conducted for new or emerging dApps. Therefore, when seeking reliable projects, we advise avoiding unvetted investments and prioritizing those audited multiple times by reputable security companies.
Can BSC Bridges Prevent Hacks or Restore Pre-Attack States?
The short answer is no. Bridges cannot prevent hacks or reverse suspicious transactions. Attackers often use bridges to transfer stolen assets to other chains, reducing the likelihood of capture. Currently, there are over ten bridges between BSC and other blockchains (e.g., Ethereum, Bitcoin, Tron), processing thousands of transactions per minute. Even bridge operators struggle to identify and halt suspicious transactions. In recent incidents, hackers used the Anyswap bridge seven times to move stolen assets off the BSC blockchain.
It is also worth noting that not all bridges have anti-fraud mechanisms (e.g., anti-money laundering, blacklisting), and many still do not collaborate with professional on-chain analysis or security firms to mitigate risks.
How Can I Report a Scam?
PeckShield, one of the BSC ecosystem's key security partners, provides a convenient way to report scams or suspicious projects.

Building a Safer Blockchain Together
Many community-driven initiatives aim to enhance BSC ecosystem security and protect user funds and data. Security firms like PeckShield and CertiK assist with audits, threat intelligence, and security options, while many projects maintain internal security teams.
The BSC core team continues to collaborate with industry-leading security companies to develop better infrastructure and services:
- The bounty program will onboard new partners to provide more proactive penetration testing for early issue identification.
- New specialized partners will be identified to establish a BSC SAFU fund or insurance protocol.
In light of recent attacks, we call on the community to take action:
- If you are a BSC or dApp user:
a. Expand your knowledge by participating in community education and awareness campaigns organized by various BSC communities, and help spread awareness.
b. Conduct your own research on projects and avoid investing in speculative ventures. Learn how to identify DeFi scams and keep your knowledge up to date.
c. Seek additional information from trusted sources like the CertiK Security Dashboard for multi-faceted insights into BSC projects. - If you are a developer or project, focus on enhancing your reputation, security, and user trust:
a. Attend "BSC Security First" workshops to learn best practices.
b. Conduct at least two audits (more are better) and actively collaborate with reputable security companies to maintain ongoing analysis of potential vulnerabilities.
c. Launch a bug bounty program or use third-party platforms like Immunefi to incentivize community testers to identify issues early.
d. Allocate a portion of funds to SAFU-like insurance projects to protect users and their capital.
e. Improve transparency by clearly communicating all major upgrades and roadmap changes, and engage with developer and user communities.
Events over the past nine months have exposed weaknesses in critical infrastructure and services. We must rebuild these systems to accommodate rapid growth in user numbers and network activity. As a community-driven decentralized ecosystem, BSC can only survive and thrive if community members work together cohesively.
The BSC ecosystem will face many challenges in the coming months. Building a decentralized, scalable, and secure blockchain is not easy. During this time, we need your support and welcome your feedback.
We are conducting security workshops with top projects on BSC. Participating in these sessions is an excellent way to understand safety in a decentralized, permissionless environment. Join us!
Frequently Asked Questions
How does BSC's security compare to Ethereum's?
BSC uses a Proof of Staked Authority (PoSA) consensus mechanism, which is faster and more scalable but slightly more centralized than Ethereum's Proof of Work. However, both networks face similar DeFi security challenges, such as smart contract vulnerabilities and phishing attacks. Users should exercise equal caution on both platforms.
What are the most common types of scams on BSC?
Common scams include rug pulls (where developers abandon a project and take funds), fake token listings, phishing websites impersonating legitimate dApps, and Ponzi schemes disguised as yield farming opportunities. Always verify contract addresses and use trusted platforms.
Can stolen funds on BSC be recovered?
Due to its decentralized nature, recovering stolen funds on BSC is extremely difficult. Transactions are irreversible. While some centralized exchanges might freeze assets if notified quickly, prevention through secure practices is the best strategy. 👉 Explore more strategies for protecting your investments.
How can I check if a dApp has been audited?
Most audited projects proudly display their audit reports on their official websites and social media. You can also cross-check on auditor websites like CertiK or PeckShield. Avoid using dApps that haven’t undergone at least one professional audit.
What is a 'honeypot' scam in DeFi?
A honeypot scam is a malicious smart contract that appears to allow you to buy a token but prevents you from selling it. The contract code is designed to trap your funds. Always review a contract’s code on a block explorer before investing, especially in unknown tokens.
Are hardware wallets safe for storing BSC assets?
Yes, hardware wallets like Ledger or Trezor provide robust security for BSC assets (e.g., BNB or BEP-20 tokens) by keeping private keys offline. They are highly recommended over software wallets for storing significant amounts of cryptocurrency.
