COTI has partnered with cybersecurity firm Sayfer to reinforce the security of its expanding privacy-focused blockchain infrastructure, following the completion of independent audits on key components of its ecosystem.
The collaboration positions Sayfer as a long-term security advisor as COTI rolls out new privacy products, including private token standards and a dedicated privacy portal. The move comes as demand grows for secure, privacy-preserving solutions across Web3 applications.
Strengthening privacy in Web3 requires combining advanced tools like zero-knowledge proofs, MPC, and decentralized identity with strong, end-to-end security practices. Since blockchain systems are transparent and hard to change, protection must cover smart contracts, infrastructure, and user-facing apps. Security audits are critical. This includes smart contract reviews, penetration testing, formal verification, and continuous monitoring.

Smart contract audits completed for privacy stack
Sayfer conducted detailed audits on COTI’s upcoming private ERC-20 token framework, designed to enable encrypted balances and confidential transactions on-chain. The audit covered core elements such as encryption logic, key management systems, and transaction handling mechanisms, with all identified issues resolved before deployment.
The firm also reviewed the smart contracts behind COTI’s planned Privacy Portal, a tool that allows users to convert public tokens into private assets and back within a single interface. The system is built to streamline access to privacy features while maintaining low transaction costs and high processing speed.
In addition, upgrades to the COTI integration with MetaMask include expanded support for confidential token standards and new privacy features such as private NFTs and multi-network functionality.
Long-term security strategy expands with continuous monitoring
Beyond initial audits, Sayfer will support COTI with ongoing security oversight as the platform scales. The firm is also developing an AI-driven monitoring system designed to provide continuous auditing, automated vulnerability detection, and real-time security insights across smart contracts and infrastructure.
Meanwhile, regarding web3 security, new findings highlight growing pressure on the Web3 sector as repeated breaches continue to expose weaknesses in decentralized finance infrastructure. Losses are increasingly driven by non-technical attacks, showing a shift in how crypto platforms are being targeted.
