01Intent
Stop a transfer before it moves
A signature that decides and moves value in one click leaves no window to review or cancel. Sensitive work starts as a request that clears policy first.

What changes
Control between intent and settlement
Sensitive moves get a real process before they settle — and you keep the keys.
02Phases
Keep approvals on the path to completion
Approvals that live in chat disappear at the signature. Waiting periods, roles, and permitted targets stay on the path until the transfer completes.
03Rules
Change who can act without redeploying
Permissions frozen at deploy mean another release just to change who may act. Update roles and limits at runtime — no redeploy.

How it works
Intent clears policy before it can settle
So a team can decide who may act, and under what conditions, before anything settles — without putting a person in front of every transaction.
- 01 Request A permitted role records the intent. Nothing moves yet.
- 02 Wait A window you set — review, escalate, or cancel.
- 03 Approve A different person signs off. Two-person control by design.
- 04 Execute Only then — and only against permitted targets.
- 05 Evidence Who did what stays on-chain with the operation.
Solutions
What becomes possible when control comes first
Share control without sharing keys — and put a process between intent and settlement, not only at the signers.
A multisig that counts signatures, not roles
Treasury
Who may request, wait, and approve — before anyone can clear a payment alone.
Off-chain process invisible on-chain
Approval Workflows
Request, wait, and approve on-chain — not in a chat thread that never settles with the transaction.
Hardware that protects the key, not the decision
Personal holdings
Cancel a transfer you did not mean while it is still waiting to settle.

One system, two doors: run it in the browser, or build the same rules into your own.
Trust
Evidence you can check
Each claim carries its own scope, and links to something you can open and check.
