Description
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.
x402: FRICTIONLESS PAYMENTS
BlockVault implements the x402 open standard. Services request payment via HTTP headers, you approve once, access unlocks.
• Gasless (providers pay gas via EIP-3009) • USDC-optimized across Ethereum, Polygon, Base, Arbitrum, Optimism, BSC • One-tap approval: see what you're paying, confirm, done • Automatic retry with cryptographic proof • Any ERC-20 via Permit2
No redirects. No pop-ups. No manual retries.
AI + x402 = INTELLIGENT PAYMENTS
• Agent detects premium content, shows approval, unlocks access • Buy GPU credits via x402 + USDC • Agent builds transactions. You tap once. • Full audit trail
Your AI makes decisions. x402 executes them.
