Three primitives for agentic finance.
Adopt one. Combine all three. jStack composes around the way your agents already work.
01
Wallets
jstack.wallets
Programmable wallets scoped to a single agent or task. Provision in milliseconds, fund from your treasury, and reconcile every cent.
- Per-agent and per-task wallets
- Sub-balances, holds, and reservations
- Built-in ledger with double-entry accounting
02
Pay
jstack.pay
A unified API across cards, ACH, wires, and stablecoin rails. Every transfer is idempotent, traceable, and webhook-driven.
- Cards, ACH, wires, stablecoins
- Idempotent transfers with retries
- Webhooks for every state transition
03
Guard
jstack.guard
A declarative policy engine for autonomous spending. Limits, allowlists, approval flows, and anomaly detection — all versioned like code.
- Spending limits and time windows
- Merchant and counterparty allowlists
- Inline human approvals
