Differentiator

An AI co-pilot
with on-chain guardrails.

Two layers, one philosophy: agents never bypass your wallet policy. Natural language becomes intent. Intent becomes a transaction preview. Only you — or a session key you scoped — can sign.

Natural-language trader
Type "long ETH 5x with $500, stop loss at -10%" — the assistant parses intent, previews the trade, and hands you an unsigned transaction.
Autonomous agents
Solana program-derived session keys with scoped policies: spending caps, whitelisted markets, max leverage, size limits, time expiry, kill-switch.
Defense in depth
Strict schema validation, hard on-chain caps, oracle price bands, per-block OI limits. Prompt injection cannot exceed your scope.
