Transaction Approval

Overview

Approval workflows reduce the risk of unauthorized or incorrect transactions. A consumer wallet may require a passcode or hardware confirmation. A company treasury can require two finance officers, a compliance review, and a final signer. A smart account can enforce spending limits or destination allowlists directly on-chain.

The proposed transaction should be immutable or versioned during approval. If the amount, destination, fee, or call data changes afterward, prior approvals should no longer apply. Signers need a human-readable view of the exact transaction, not only a reference number from another system.

Automated approval can evaluate risk rules such as transaction value, new destination, asset type, velocity, and current network conditions. High-risk cases can move to manual review. Emergency or override actions should be logged and restricted.

Approval systems must handle expiry and cancellation. A transaction approved with a current nonce or fee estimate may become stale before signing. Replacement transactions should clarify whether they preserve the same business intent or require new authorization.

The blockchain does not know an organization’s internal approval policy unless the policy is enforced by a smart contract or threshold signature. Off-chain approval records should therefore remain linked to the final signed bytes and transaction hash for auditability.

Approval evidence should remain linked to the signer and final transaction hash. A screenshot or generic ticket is insufficient when several similar transactions exist. Systems can hash the unsigned payload and include that digest in the approval record. For automated policies, the rule inputs and decision result should be stored. This makes it possible to prove that the transaction broadcast later was exactly the one reviewed and approved.
