About this app

BlockVault is your intelligent gateway to decentralized finance. Self-custody HD wallet with an on-device AI agent and HTTP-native payments, running privately on your phone.

ON-DEVICE AI. PRIVATE BY DEFAULT

Your AI financial assistant runs entirely on your device via LiteRT. No cloud. No data leaks. No subscriptions.

• Gemma4 4B inference without internet
• Connect to LM Studio on your PC for larger models (7B, 13B+)
• Delegate GPU via x402 pay-per-token when you need more power
• ReAct reasoning: the agent thinks, acts, iterates until it's solved

Your conversations never leave your phone.

TEACH YOUR AI NEW TRICKS

BlockVault's agent isn't static. You can expand its capabilities with custom skills and built-in tools:

• Create: write new skills from scratch using the built-in markdown editor
• Edit: refine existing skills, adjust prompts, tweak instructions on the fly
• Save: persist your custom skills locally for reuse across conversations
• Graph: visualize portfolio data, price charts, and analysis results directly in-chat
• Powerful MD editor: full markdown skill authoring with syntax highlighting and live preview

Built-in skills included:

• Portfolio Analyst: multi-chain analysis, diversification scoring, risk profiling
• Market Analyst: OHLCV technicals, support/resistance, sentiment, predictions
• Alpha Detector: trending tokens, smart-money flows, social signals, conviction scores
• Persistent Memory: remembers preferences across conversations
• Web Search: DuckDuckGo for breaking news and market data

Your agent grows with you. Build the skills you need, share them, or keep them private.
