Compare who can authorise spending

In a single-signature wallet, one usable signing key can authorise a transaction. A multisignature wallet requires a defined threshold of signatures, such as two of three keys. The benefit depends on how those keys are generated, stored and operated. If one person or system controls enough keys, the apparent distribution may not provide independent control.

Using different devices can reduce some common dependencies, but it does not create immunity to flawed software, exposed backups or coordinated compromise. Examine the exact arrangement instead of treating a device count as a security rating.

Recovery includes configuration as well as keys

A recipient may need public-key information, derivation paths, the signing threshold and the appropriate wallet software in addition to usable key backups. Preserve the wallet’s supported configuration export and official restoration instructions. Export formats are not interchangeable simply because they describe similar data.

Losing a particular descriptor file does not prove recovery is universally impossible, but reconstructing missing configuration can be difficult. Avoid making that reconstruction the plan. Verify what the wallet actually exports and store usable copies separately from the complete set of signing secrets.

Test coordination before adding complexity

Start with a separate harmless test wallet. Check whether the intended signers can locate the configuration, verify a receiving address and explain the approval sequence. Identify what happens if a signer, device or location is unavailable. Record which combinations were tested without disclosing the live keys.

A technically stronger design can become harder to maintain. Ask whether the recipient understands the threshold and knows when to seek qualified help. Review after replacing a signer or changing the wallet setup. Follow official documentation for any action involving live funds; do not experiment by deleting the only working configuration.

Keep the handoff narrowly scoped

ZeroLatch can deliver a scoped inventory and instructions after a missed check-in and safety period. It does not transfer assets, establish legal authority or confirm death. Simple permits authorised service-managed key recovery; Private requires a separate password or ZeroLatch recovery phrase. Neither option replaces an independent backup or a real recipient rehearsal. Start with harmless information and read the security model and backup checklist.

A delivery might contain a wallet map, the location of independent configuration backups and co-signer contacts. A ZeroLatch Private secret is separate from a wallet seed or wallet passphrase. Do not combine every factor in one delivery or describe ZeroLatch as the signing authority for the wallet.
