跨链桥连接不同的链，因而是高风险目标。我们用一套聚焦的流程，确保你的桥在每个角度上都安全。
检查最终的桥合约、架构与设计文档以确定审计范围，并按桥的复杂度、涉及的链与风险面给出定制报价。如有需要可签署 NDA。
界定范围与费用
检查最终的桥合约、架构与设计文档以确定审计范围，并按桥的复杂度、涉及的链与风险面给出定制报价。如有需要可签署 NDA。
确认条款与排期
敲定合作细节，包括价格与审计日程，并设定明确里程碑，让桥审计的进度与你的上线或升级计划对齐。
执行审计并验证修复
结合自研工具与人工评审完成一次完整的跨链桥安全审计，把发现同步给你的团队并复核修复。复杂的桥可能需要多轮审计。
交付报告与缓解建议
提供一份签署的审计报告，涵盖漏洞、风险影响与修复建议，并给出清晰指引，帮助强化桥的安全性、降低跨链攻击风险。
我们把深厚的跨链经验与自研工具结合起来，守护链与链之间复杂的资金与消息流转。
“We had a great experience working with BlockSec on the security testing of Mega-EVM, our stateless validator, and the SALT data structure. They're responsive, diligent, and easy to collaborate with, with a fast feedback loop throughout the audit. Their deep expertise across both smart contracts and node-level systems made them a strong partner for complex infrastructure work.”
“On the audit side, the BlockSec team has left a very positive impression on us. Their audits are never a mere formality; instead, they dive deep into contract implementation details and specific business logic, covering edge cases and extreme scenarios that are often overlooked. The entire process was smooth and highly efficient. Their bug localization and remediation advice were clear and actionable, helping us significantly reduce potential security risks before product launch.”
“BlockSec has built a strong reputation for conducting highly technical audits for blockchains and smart contracts. Supporting Solidity (EVM-compatible ecosystems), Rust (NEAR & Solana), and Go (Cosmos), the company primarily relies on thorough manual reviews, enhanced by automated differential fuzzing tools and static analyzers. This approach allows BlockSec to identify deep logic flaws in code and provide actionable recommendations to ensure project security before launch.”
“BlockSec's deep expertise in smart contract security has been invaluable to exSat. Their rigorous audits consistently uncover subtle yet critical vulnerabilities, delivering clear, practical remediations. With their meticulous, code-level scrutiny, we gain unparalleled confidence in our protocol's integrity—making BlockSec our trusted partner for secure, resilient smart contracts.”
我们使用自己的专用安全工具，例如进阶模糊测试器与静态分析器 —— 这些是其他审计机构没有的。
我们用数学证明（形式化验证）来确保代码中最关键的部分不可能出错。
我们有实绩为证：曾帮项目避免巨额损失，也在坏人之前发现过头部协议中的关键漏洞。
我们不用「一套打天下」的做法，而是针对你项目的独特之处专门设计测试，捕捉边界情况的问题。
