Create the policy
Choose a guardian, fixed beneficiary shares, and an inactivity window. Your wallet signs the vault deployment.
Self-custodial succession on testnet
Your assets should not become inaccessible when you do.

The governing principle
Automation may execute your policy. It may never rewrite it.
A visible, reversible path
Inactivity starts a review—not an irreversible transfer.
Keep the heartbeat
A small owner transaction resets the clock. Nothing depends on an email, server login, or model decision.
Review the grace period
After inactivity, KeeperHub may open a time-locked review window. The owner can reactivate; the guardian can veto.
Settle and verify
KeeperHub finalizes only after the contract permits it. Every beneficiary claims independently from the vault.
Authority stays narrow
Three safeguards. No hidden administrator.
The owner controls the policy and active funds. The guardian can stop settlement, never redirect it. Contract rules constrain every executor.
Self-custodial vault
No application server, guardian, or KeeperHub wallet can choose a new recipient.
Guardian veto, not custody
A guardian can halt a questionable transition during grace; only the owner can reactivate.
Pull-based claims
Finalization snapshots every allocation, so one unavailable beneficiary cannot block another.
Execution with receipts
KeeperHub executes only what the vault permits.

LastWish is not a legal will, probate service, or proof-of-death system. It executes a pre-authorized digital-asset policy based on onchain inactivity. This MVP uses testnet assets only.
