Software agents can call services and submit transactions, but payment authority creates a security boundary. The first design question is what an agent is allowed to do when a tool, prompt or external service behaves unexpectedly.
Follow the evidence
Trace how the event could reach markets, then inspect a competing explanation.
Compare explanations
Switch lenses to see what each account explains—and what remains uncertain.
Give the agent a narrowly scoped credential, transaction caps, approved destinations and expiry. Keep signing keys outside the model context; require separate approval for high-value or unusual transfers and log every instruction and response. Test prompt injection, tool failure, duplicate requests, stale balances and network changes. A successful demo does not establish safe behavior across those edge cases or provide a recovery path for a completed transaction.

Clarify the custodian, payment provider, wallet permissions, dispute route and data retention. Decide how to revoke access quickly and who monitors the system when an agent operates unattended. Automation can reduce manual steps while creating new operational dependencies. Review measurable safeguards and independent assessments rather than treating an AI label as evidence of reliability.
A transaction capability is a permission, not a personality
An agent may request a payment through an API or wallet interface. The surrounding system determines which assets, recipients, amounts and networks are available, and whether a person approves the final instruction.
A product announcement establishes that a capability was described, not that it is broadly available, secure in every use case or suitable for unsupervised funds. Verify the current documentation and deployment scope.
Use limits, allowlists and a human stop path
