SENTRY
Building the Next Generation
Security Standard for the Solana
Ecosystem
Sentry is a security-first protocol for Solana, built with advanced cryptography and robust architecture to tackle network instability, app vulnerabilities, and MEV — creating a safer, more reliable blockchain for developers and institutions.

Solana's Security Challenges
Despite Solana's exceptional performance, its ecosystem has faced a series of security and stability issues during its development. Understanding these challenges is the first step towards building a more resilient future.
Significant Losses from Application-Layer Vulnerabilities
Network Instability
Solana has historically experienced 7 major outages, caused by various factors including bot-driven spam and client errors, impacting user confidence and application availability.
MEV Spam
Research indicates that MEV (Maximal Extractable Value)-driven arbitrage bots and similar transactions occupy up to 40% of block space, exacerbating network congestion and affecting the transaction experience for regular users.
Sentry: Proactive Security Architecture
Sentry is not about passive fixes, but proactive defense at the architectural level. Through a layered security model and comprehensive vulnerability mitigation strategies, we provide a solid security foundation for dApp developers.
Common Solana Vulnerability Mitigation Matrix
Three Pillars of Technology
Sentry's security is rooted in the innovative application of three cutting-edge cryptographic technologies, which together form the core of the protocol's privacy and security.
Zero-Knowledge Proofs (ZKPs)
Enable verification while preserving privacy, facilitating confidential transactions and identity authentication.
Multi-Party Computation (MPC)
Distribute private key management, eliminating single points of failure and enhancing asset security.
Fully Homomorphic Encryption (FHE)
Perform computations directly on encrypted data, enabling unprecedented on-chain privacy protection.
Development Roadmap
We have a clear, phased plan for Sentry's development, with each step centered on security, stability, and community engagement.
