The wall

AI got good.
Procurement didn't.

Frequently asked

Questions,
answered.

No. Your balance lives in a self-custodial wallet in a secure enclave · your keys, your money. Sault is a control layer that sits above it, co-signing transactions under rules you set.
Your balance is in dollars. You top up in dollars. You see receipts in dollars. Chains, gas, and tokens stay invisible.
You always prepay into your own wallet before Sault can act. No per-user credit, no float exposure to you. Sault's own treasury pools are multisig with per-transaction caps.
Private beta is live with a small cohort of builders. Public waitlist invites roll out in waves starting Q3 2026 · in the order you join, with priority for people who tell us what they're building.

Your agent is waiting on you.

Stop being the procurement department for your own agent. Top up once. Let it run.
