COTI has entered into a partnership with Sayfer to reinforce the security framework supporting its privacy-focused ecosystem. Sayfer, established in 2019, has built a reputation in the blockchain security space, having worked with major industry participants such as MetaMask, 1inch, Polkadot, Tezos, and BNB Smart Chain. The firm has reportedly maintained a strong security record, with no successful hacks recorded among its clients.
Under the agreement, Sayfer will serve as a long-term security advisor to COTI, supporting the project as it prepares to launch new products and expand its privacy infrastructure. The collaboration reflects a growing emphasis on proactive security measures within the Web3 ecosystem, particularly as projects handle increasingly sensitive data and financial transactions.
The partnership establishes Sayfer as a long-term security advisor to COTI, reinforcing the infrastructure behind its privacy protocol as new products are prepared for launch.
Comprehensive Audits of Core Components
The initial phase of the collaboration involved detailed smart contract audits of two critical elements within the COTI ecosystem: private ERC-20 tokens and the Privacy Portal. Sayfer conducted an in-depth review of the private token framework, examining encrypted balance logic, remote procedure call handlers, key management processes, token validation mechanisms, and encrypted data handling.
The audit process was carried out at a granular level, with each component analyzed line by line to identify potential vulnerabilities. Following the review, all identified issues were addressed by the COTI development team prior to deployment, ensuring that the system met stringent security standards before going live.
The Privacy Portal, a web-based application designed to facilitate seamless conversion between public and private tokens, also underwent extensive testing. Sayfer’s researchers performed stress tests on its smart contracts to evaluate performance and resilience under various conditions, helping to ensure reliability and user safety.
Advancing Privacy Features and User Interaction
COTI is also enhancing user interaction through its integration with MetaMask Snaps. The latest version of its Snap will include full support for ctUint256, a confidential ERC-20 standard introduced through the Helium Mainnet upgrade. This functionality is expected to enable advanced privacy features for token transactions.
In addition to supporting confidential tokens, the updated interface will introduce capabilities for private non-fungible tokens, allow users to switch between mainnet and testnet environments, and offer an improved transaction flow. These upgrades are designed to provide a more intuitive and secure user experience while maintaining robust privacy protections.

The approach combines automated vulnerability detection with the expertise of experienced security professionals, enabling ongoing analysis of potential risks. COTI is expected to be among the first blockchain projects to implement this continuous monitoring framework, which could significantly improve its ability to detect and respond to threats as they emerge.
The collaboration introduces an AI-powered continuous security monitoring system, enabling real-time threat detection and strengthening long-term protocol resilience.
Strengthening Trust in Privacy-Focused Blockchain Solutions
The partnership highlights the increasing importance of security in the development of privacy-centric blockchain applications. As decentralized systems become more complex, ensuring the integrity and safety of the underlying infrastructure is critical for user trust and adoption.
By combining rigorous auditing processes with ongoing monitoring capabilities, COTI and Sayfer aim to set a higher standard for security within the Web3 space. The initiative reflects a broader industry shift toward integrating advanced technologies and best practices to safeguard digital assets and sensitive information, supporting the continued growth of decentralized ecosystems.
