Zokyo

Zokyo is a leading web3 security firm founded in 2018, on a relentless mission to make every organization leveraging blockchain technology secure from cyber threats and confident in their readiness. The company emerged from a rich legacy of innovation in blockchain security, with founder Hartej Sawhney having co-founded the world's first blockchain security company, Hosho, in 2016.

Cybersecurity Services: Penetration testing, web and mobile application security source code reviews, IoT security assessments, cloud security assessments, wallet pentesting, extension security reviews, and red team engagements with adversarial simulation.

Zokyo Econ Lab: Token economy design, due diligence as a service, long-term project support, compliance audits (including DLT Foundation and ADGM regulatory compliance), corporate structuring, DAO structuring, real-world asset tokenization, fundraising legal representation, and strategic business consulting.

Key Strengths

Zokyo brings together a global collective of top-tier ethical hackers, cryptographers, and research scientists spanning multiple continents including the United States, United Kingdom, Ukraine, Spain, Romania, India, United Arab Emirates, Singapore, Philippines, Nigeria, China, and Poland. The team holds industry-leading certifications and credentials, demonstrating their deep expertise in blockchain security.

The company advises clients across multiple blockchain ecosystems including EVM, Move (Sui, Aptos), Cosmos, Avalanche, Solana, Filecoin, Sei, Conflux, and TON, as well as wallets, cross-chain infrastructure, L1s and L2s. They support projects built with Solidity, Move, Rust, and Go programming languages.

Zokyo's rigorous security auditing process follows an 8-step roadmap: engagement and scope definition, documentation and preparation, comprehensive security review, vulnerability assessment, client review and mitigation, verification of fixes, final reporting, and post-audit support. Their audits have identified high-impact issues in 62% of security reviews, with over 1 million audited lines of code.

Notable Clients and Projects

Zokyo is trusted by leading Web3 companies including LayerZero Labs, Railgun, Umami Finance, 1inch Labs, Shido, Isle Finance, and Teahouse Finance. The company played an instrumental role in supporting the Solana Foundation's tokenized setup under the 2023 DLT Foundations Regulations of the ADGM, marking a major step in Web3 compliance. They have also formed strategic partnerships with Linea (a Layer 2 zk-Rollup platform developed by Consensys) to fortify security measures and propel innovation in the ecosystem.

Why Choose Zokyo

The company combines deep technical expertise with economic and compliance consulting through Zokyo Econ Lab, offering end-to-end support for Web3 projects from concept to execution. Their global presence and multi-ecosystem expertise make them a trusted long-term security partner for organizations looking to ship with confidence, knowing their reputation is protected.
