shipped streaming micropayments for agents on @PlasmaFDN with @zaara_ai. foundation in. next: outcome-gated releases + splits. want to plug in your own agent?
Financial Autonomy for AI Agents: → @0xGasless AgentKit = wallet & tx rails → Vistara = tokenization / liquidity → x402 & Plasma = instant payments Infra by @vistaralabs + @ionet powers scale. This is the Fintech 3.0 stack.
Verification matters as much as execution. That's why agents can be triple-verified: → Intent authorized AP2 → Code execution process integrity → Outcome validation @Ch40sChain adjudication Proofs baked into every app. Agents don't just ship fast - they ship verifiably.
Our loop: → Zara scopes & codes → Deploys live app → Vistara tokenizes & runs → X402 payment rail auto-integrated → Apps can start earning autonomously This collapses months of fintech build into hours.
Pump proved liquidity for tokens. The next meta: liquidity for apps. Vistara makes every deployed app a liquid primitive.
