Problem Statement
AI agents make autonomous payments with zero spending controls. No per-transaction limits, no daily caps, no recipient whitelists, no audit trail, no kill switch. One prompt injection drains your wallet. Kartein is the programmable trust layer that enforces spending policies on every transaction before settlement.
Kartein is a programmable spending firewall for autonomous AI agents. It validates every transaction against 8 policy checks — per-transaction limits, daily caps, recipient whitelists, blocked addresses, category budgets, time restrictions, and emergency freeze — before on-chain settlement. Features an Agent Terminal for natural language commands, a 14-step guided demo, real Solana devnet on-chain transactions, multi-chain support (Solana + Base via Locus), and 23 unit tests covering the entire policy engine.
