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
