Binance smart contracts

BNB Smart Chain (BSC) is a high-performance blockchain platform designed to support development and interaction of decentralized applications (dApps) and decentralized finance (DeFi) platforms.

BNB Smart Chain uses a dual-chain architecture of Delegated Proof of Stake (DPoS) and Proof of Authority (PoA), enabling compatibility with the Ethereum network while also providing faster transaction speeds and lower transaction fees. Thus, BSC supports smart contracts and is fully compatible with the Ethereum Virtual Machine (EVM) as well as Ethereum tools and applications. The BSC blockchain network delivers low fees, fast finality, and over 1,500 dApps in its network.

A smart contract is a self-executing, decentralized protocol stored on a blockchain that automatically facilitates, verifies, or enforces the negotiation and performance of a digital agreement between parties. For instance, a smart contract could be used to represent a legal contract emulating the logic of contractual clauses or a financial contract specifying responsibilities of the counterparts and automated flows of value.

Smart contract execution is validated by the network, while administrative permissions and upgrade controls depend on the contract’s design. The contract operates without intermediaries, relying on a network of distributed nodes to validate and execute transactions.

What does a Binance smart contract audit cover?

A BSC smart contract security audit is a process of evaluating a codebase to identify and mitigate vulnerabilities. The review is performed by one or more blockchain security researchers and involves a detailed analysis of the smart contract or protocol code. Researchers identify security issues, vulnerabilities, and inefficiencies; verify their impact through proof-of-concepts; recommend solutions, and support the implementation and testing of mitigations.

1
Setup timelines and onboarding
Our engineers will review the codebase complexity and size, estimate the timeline, and open a direct line of communication with your team.
2
The security review begins
Our security researchers review in-scope code and apply different methodologies and techniques to uncover hidden vulnerabilities.
3
Preliminary report and mitigation
A preliminary security report is delivered. Allowing your engineers an opportunity to mitigate findings using the provided recommendations.
4
Final security audit report
Once mitigations have been applied to your codebase, our researchers verify and update each issue in the report and provide any necessary additional information.

Who needs Binance security reviews?

Protocols, enterprises, and public-sector teams need independent security reviews before deploying or integrating on-chain systems. Identify vulnerabilities, assess dependencies, and plan practical mitigations.

Financial Institutions
Tokenization and blockchain rails face both technical and regulatory pressure. Provide confidence, compliance, and assurance for partners and regulators.
Consumer brands
From payments to loyalty tokens, brands must protect their users and reputation. Safeguard launches, build trust, and prevent costly security failures.
DAOs & Treasuries
On-chain treasuries and governance contracts hold critical assets. Validate security controls, reduce systemic risk, and protect community funds.
DeFi & DeX
High-value smart contracts are prime targets for exploits. Ensure vulnerabilities are found before attackers do.
Institutions & Governments
National pilots and public funds demand the highest security. Deliver transparency, resilience, and trust for citizens and stakeholders.

Syntetika: Securing Bitcoin-DeFi Infrastructure

Syntetika selected Cyfrin to conduct a pre-launch audit based on our expertise in on-chain security, proven track record, and ability to execute under tight timelines. The engagement was structured around Syntetika's security priorities: Securing staking logic, ensuring mathematical consistency in staking price calculations to prevent frontrunning and sandwich attacks, and secure asset custody within the Minter Contract. Cyfrin's track record in on-chain security, combined with a deep understanding of complex DeFi protocols and institutional requirements, made it an ideal partner for Syntetika. The team's expertise in vault-based protocols and compliance-required security assessments aligned perfectly with Syntetika's unique architecture and focus.
