General Questions

What is SentrySol?

SentrySol is a smart security system that works directly on your phone. It uses AI (artificial intelligence) to constantly monitor how you use Web3 apps. Its goal is to find and stop harmful threats before they happen, keeping your assets and trust safe.

What problems does SentrySol solve in Web3 mobile?

SentrySol helps protect you from common security issues in Web3, such as:

• Phishing: Fake messages or websites trying to trick you.

• Blind Signing: Approving transactions without knowing what you're actually signing.

• Malicious Contract Calls: Hidden code that can steal your assets.

• App Exploits: Weaknesses in apps that scammers can use.

• Wallet Draining & Address Spoofing: Attempts to empty your wallet or send funds to the wrong address. SentrySol prevents these things from happening.

What are SentrySol's main principles?

SentrySol is built on three core ideas:

• AI Directly on Device: All artificial intelligence works on your phone.

• Learning While Protecting Privacy: The system learns from new threats without looking at your private data.

• Hardware-Level Security: Uses your phone's strongest built-in security features.

Technology & How It Works

How does SentrySol protect me?

SentrySol is a smart guardian that works in the background. It continuously analyzes your behavior (like your tapping speed, how you move through apps, or transaction timing) to create your unique "behavioral fingerprint." If something looks unusual or suspicious, SentrySol will stop the dangerous transaction and alert you.

What does "on-device AI" mean for my security and privacy?

"On-device AI" means all SentrySol AI processes happen directly on your phone. This offers big advantages:

• Super Fast: Threat detection happens instantly, without waiting for an internet connection.

• Highly Private: Your personal behavioral data never leaves your phone.

• Continuous Protection: Security stays active even when you're offline or have an unstable internet connection.

• Resource Efficient: It uses lightweight AI models designed specifically for phones.

How does SentrySol stay updated on new threats without compromising my privacy?

SentrySol uses Privacy-Preserving Federated Learning. This means the AI system learns from global threat patterns by sharing only general information (not your personal data) from many devices. So, the system gets smarter at detecting new threats without seeing your private data.

How does SentrySol use my phone's built-in security features?

SentrySol connects closely with special security parts of your phone, like Solana Mobile's SeedVault. This is like a digital safe inside your phone. SentrySol uses this safe for important security operations and its AI data, making it very hard for attackers to get in. This ensures SentrySol's AI decisions are trustworthy.

What is "blind signing" and how does SentrySol prevent it?

"Blind signing" is when you approve complex Web3 transactions without truly knowing what you're signing, often because the text is unreadable or there's a scam. SentrySol's Signature Validator and Phishing Interceptor feature checks your signing requests. It compares what you intended to do with what is actually being requested. If there's a mismatch or malicious intent, SentrySol will stop the transaction and alert you.

Does SentrySol have a chat feature?

Yes, SentrySol can include a secure, decentralized, peer-to-peer messaging app that works over Bluetooth mesh networks. This means you can communicate without internet, servers, or phone numbers—just pure encrypted communication.

Target Users & Use Cases

Who is SentrySol designed for?

SentrySol is designed for various users in the Web3 mobile world:

• Solana Mobile Seeker Users: As our main focus, SentrySol provides better app security directly on their phones.

• Web3 Wallet Providers: We offer tools (SDKs) so they can add SentrySol's security to their wallets.

• dApp Developers: We provide tools and guides to help them build safer apps.

• Mobile OEMs (Phone Manufacturers): We partner with them to pre-install SentrySol as a core security feature on Web3 phones.

What are SentrySol's main uses?

SentrySol helps in many Web3 situations, such as:

• Preventing Blind Signing.

• Securing DeFi (decentralized finance) interactions.

• Protecting NFT (non-fungible token) transactions.

• Preventing wallet draining.

• Fighting address spoofing.

• Assisting with blockchain security analysis.

Is SentrySol available on Solana Mobile Seeker?

Yes, SentrySol initially focuses on Solana Mobile Seeker users. It provides enhanced app security directly on the device, leveraging built-in security features like Seed Vault.

Competitive Comparison

How is SentrySol different from regular antivirus software (e.g., Kaspersky)?

Regular antivirus protects against common viruses. SentrySol is specialized for Web3, understanding how transactions and decentralized apps work to fight more advanced scams that regular antivirus can't detect.

How does SentrySol compare to device security platforms (e.g., Samsung Knox)?

Platforms like Samsung Knox secure your phone's operating system. SentrySol adds to this by providing a smart security layer specifically for your interactions with Web3 apps, protecting things that general OS security doesn't cover.

How is SentrySol different from cloud-based Web3 security solutions (e.g., Fireblocks, Zengo, Certik)?

Cloud-based solutions rely on central servers. SentrySol works entirely on your phone. This means better privacy (your data doesn't leave your device) and continuous protection, even when you're offline.

Does SentrySol replace hardware wallets (e.g., Ledger, Solana SeedVault)?

No, SentrySol complements hardware wallets. Hardware wallets secure the final signing process and your private keys. SentrySol provides smart, real-time behavioral analysis before you sign a transaction, preventing you from being tricked into approving the wrong thing.

Future & Availability

What are SentrySol's plans for the future?

Our plans include:

• Late 2025: Launching SentrySol for Solana Mobile Seeker and starting pilot programs.

• Early 2026: Introducing tools (SDKs) for other Android Web3 wallets and improving our AI capabilities.

• Late 2026: Expanding to other major Web3 mobile ecosystems, exploring partnerships with phone manufacturers, and continuously enhancing our AI learning capabilities.
