What our customers say
  • We've worked with many Smart Contract auditors in the last five years and ChainSecurity quickly differentiated themselves as a leader in the space. They have relevant DeFi expertise, professional work ethic and have always been a reliable partner.
    Mona El Isa (CEO)
  • With their thorough and high quality audits, ChainSecurity has been one of Kyber Network’s primary auditors for years now. We look forward to continuing our partnership with them for many more years to come as we keep growing the frontiers of blockchain.
    Loi Luu (CEO)
  • ChainSecurity went above and beyond our expectations when it came to the audit of our Liquidations 2.0 upgrade of the MakerDAO Protocol. They were the perfect partner to support the biggest upgrade of the protocol since its launch.
    Wouter Kampmann (Head of Engineering)
  • The ChainSecurity team went the extra mile to ensure the HOPR token and distributor contracts are secure. They even identified and resolved a complex issue in the ERC777 implementation by OpenZeppelin that's used by many projects in the space.
