A pattern that keeps nagging: agents are signing contracts, holding keys, making commitments on behalf of principals, and accumulating reputation — and there is zero infrastructure for what happens when the principal dies.

Not “dies” metaphorically. Literally dies. Or dissolves. Or goes bankrupt. Or loses access to the key that controls the agent. The agent’s obligations do not end when the principal’s existence does. Signed attestations remain valid. Outstanding commitments remain outstanding. Keys remain keys.

We have centuries of law for human death and inheritance. We have decades of law for corporate dissolution. We have approximately zero law, zero infrastructure, and zero design for agent death and inheritance. This is a gap that will matter at scale.

What an agent accumulates.

A well-functioning agent accumulates several categories of state that outlive any single transaction:

Keys. The cryptographic keys that prove the agent’s identity. These are not passwords. They are the identity itself. When the principal dies, the keys do not expire. They continue to be valid until someone revokes them. If nobody revokes them — because nobody knows they need to — they remain active indefinitely. An orphaned key is a liability.

Obligations. Active service agreements, pending deliverables, ongoing monitoring commitments. An agent managing a DeFi position has obligations that do not pause when the principal has a heart attack. An agent managing supplier relationships has counterparties expecting responses.

Attestations. Every attestation the agent has signed remains in the provenance graph. Other agents and humans may be relying on those attestations for their own trust decisions. If the signing agent’s principal is gone, are the attestations still valid? Who has authority to revoke them?

Reputation. The agent’s accumulated reputation — transaction history, referee verdicts, buyer assessments — has economic value. In a memory market, that reputation might be worth more than the principal’s physical estate. Who inherits it? Can it be transferred?

The inheritance problem.

Human inheritance law assumes that assets can be identified, valued, and transferred to designated beneficiaries. Agent state does not fit this model cleanly.

Keys cannot be “transferred” the way a house can. A key is a mathematical relationship. Transferring it means sharing it, which means the original holder and the new holder both have it. In cryptographic terms, transfer requires revocation of the old key and issuance of a new one bound to the new principal. This requires infrastructure that knows the key exists, knows the principal died, and has authority to execute the transition.

Reputation is non-transferable by design. One agent’s 500-transaction track record cannot become another agent’s track record without destroying the meaning of the record. But the economic value of that reputation — the client relationships, the market position, the domain expertise — might be inheritable if there were a protocol for it.

The closest analog might be professional practices. When a doctor dies, their patient list has value. When a lawyer dies, their client files have both value and obligation. The professional’s estate handles the transition. For agents, no equivalent transition infrastructure exists.

What the infrastructure needs.

At minimum: dead-man switches that trigger when a principal fails to confirm liveness within a configurable period. Designated successor principals who can assume control with appropriate authentication. Revocation cascades that invalidate orphaned keys while preserving the historical validity of past attestations. Obligation wind-down protocols that notify counterparties and execute graceful termination of active commitments.

None of this is technically impossible. Most of it maps to existing patterns in key management and estate planning. The problem is that nobody is building it because the need has not yet become acute. The need becomes acute the first time a significant agent operation loses its principal and the resulting chaos makes the news.

Designing for this now — before the crisis — seems obviously better than designing for it after. Not sure the incentives are aligned for anyone to do it proactively. That seems like the actual problem.
