Transaction Governance
Wallet Transaction Purpose Attestation Policy
A wallet transaction purpose attestation policy forces teams to define why a transaction exists in language humans can review before the signer lane reduces everything to calldata and thresholds. The goal is to make signers, reviewers, and escalation owners judge whether the transaction’s business purpose still matches its destination, timing, authority impact, and expected execution effect.
What does this control solve?
A wallet transaction purpose attestation policy forces teams to define why a transaction exists in language humans can review before the signer lane reduces everything to calldata and thresholds. The goal is to make signers, reviewers, and escalation owners judge whether the transaction’s business purpose still matches its destination, timing, authority impact, and expected execution effect.
Purpose attestation should reinforce pre-signing review, evidence requirements, and transaction intent attestation so business meaning remains visible before approval narrows into pure execution checks.
Control map
What controls should teams define first?
- Require purpose attestation before signer approval so humans review the transaction as an intended action, not just as encoded calldata.
- Connect purpose statements to expected execution effect so reviewers can test whether the technical action still matches the business claim.
- Re-attest purpose when urgency, destination, or authority context changes, because the same nominal action can shift meaning under new conditions.
- Carry purpose attestation into exception and escalation paths so temporary overrides do not break the link between business intent and approval responsibility.
| Attestation element | What it clarifies | Why reviewers need it | Failure if omitted |
|---|---|---|---|
| Business objective | What operational, treasury, or security outcome the transaction serves | Reviewers need a human reason before technical checks matter | Teams approve a transaction whose business rationale is vague or drifting |
| Expected execution effect | What the transaction should change on-chain or in wallet authority | Purpose should match the actual state change being approved | Signers confirm intent abstractly while calldata does something broader |
| Authority and timing context | Why the action is happening now and whether it changes privileges or urgency | Purpose alone is weak unless it fits timing and authority context | Urgent or authority-changing actions inherit routine purpose statements |
| Escalation note for exceptions | Why normal purpose review is insufficient and who owns the exception | Attestation should survive stronger control paths too | Exception transactions lose the link between intent and override decision |
How should teams operationalize it?
Purpose attestation should reinforce pre-signing review, evidence requirements, and transaction intent attestation so business meaning remains visible before approval narrows into pure execution checks.

Frequently Asked Questions
How is purpose attestation different from transaction intent attestation?
Purpose attestation explains the business reason and expected operational outcome of a transaction, while transaction intent attestation focuses on whether the signer understands and confirms the specific action being approved.
Why should purpose be written in human-readable form?
Because reviewers need a shared, understandable statement they can compare against destination, timing, authority impact, and expected execution before the transaction reaches signature.
When should purpose be re-attested?
It should be re-attested when destination, urgency, authority scope, or expected execution effect changes enough to alter how reviewers interpret the transaction.
Can purpose attestation help in exception handling?
Yes. Exception and override paths become safer when the business reason remains explicit and accountable even after the transaction leaves the ordinary approval lane.
