Continuity rules
without a custodian.

Bitcoin and crypto self-custody has a hard human problem: what happens to funds when the owner can no longer act? Mortal Vault explores a continuity lifecycle with no administrator, no custody service, and no emergency override — the rules live in the contract, and the risks stay visible.

Make a high-consequence self-custody lifecycle understandable without hiding the irreversible risks or implying legal and security guarantees the product cannot make.

• The continuity model: owner check-ins, inactivity windows, delayed claims
• Solidity contract lifecycle and its bounded state machine
• Owner and beneficiary interfaces in Next.js, with network, contract, and transaction state exposed
• Event-backed activity history and deterministic reminder planning
• Security work treated as a release gate: threat model, adversarial tests, fuzzing, invariants, static analysis, balance caps

• A bounded contract lifecycle: create, fund, update, check in, withdraw, close, request a claim, cancel it through owner activity, and execute only after both time gates
• Separated owner control and a shareable beneficiary claim path
• Contract events parsed into bounded activity views that survive refreshes
• Adversarial, fuzz, invariant, and static-analysis gates inside the repository
• Testnet-first network and release configuration with explicit release blockers

The repository is private; the demo capture below shows the working owner-facing surface from the local application. Wallet connection and chain actions stay outside this public frame. Deeper evidence — the contract lifecycle, tests, and threat model — can be walked through in a conversation.

Private alpha in active development. Mainnet remains blocked by independent review, external wallet exercises, monitoring, and demonstrated demand.

A MaydaLabs-owned lab product. Mehmet owns the product definition and implementation, with every security and release claim kept behind explicit evidence gates.

• Contracts are unaudited and must not hold meaningful funds.
• No administrator, custody service, legal determination, or emergency override exists.
• This is not legal inheritance, probate, identity verification, or key recovery.
• No mainnet claim is made before independent review and the other release gates pass.
