Built for how finance teams work.

Every payment is checked before money moves, every purchase is recorded, and you can stop any agent instantly.

Rules before payments

Limits and allowed categories are checked before any money moves, not afterwards.

A record you can trust

Each entry is linked to the one before it, so any change to past records is detected.

Clear accountability

Every agent belongs to a verified company, and every purchase is tied to the agent that made it.

Instant control

Freeze a card, lower a limit or block a merchant. Changes apply immediately.

See how an edited record gets caught

Each entry below has a fingerprint (a hash) made from its own details plus the fingerprint of the entry before it. Change one amount and its fingerprint no longer matches, which breaks every link after it.

The fingerprints are real SHA-256 hashes, calculated in your browser.

Press “Check the records” to verify every entry.
Controls

You decide what agents can do

Approvals

Purchases above a threshold wait for a person. If nobody answers in time, they’re declined.

Scoped access

Each agent has its own API key, limited to what it needs. Revoke a key at any time.

Full history

Every decision is stored with its inputs and time, so you can review exactly what happened.

Steadfield is in early access. Pilot companies start with test cards before any real money is involved. [Partner bank, licence and compliance certifications will be listed here.]
