What happens to your crypto when you die?

Right now, the answer is: nothing. Your keys die with you. Your family hires a lawyer who doesn't understand seed phrases. Your holdings sit in a wallet nobody can open. Forever.

↓

Every existing option is broken.

You can't put a seed phrase in a will. Probate is public record. A safety deposit box needs a court order to open, and by then everyone knows what's inside. A lawyer holding your keys is a single point of failure with a billable hour rate.

Existing crypto inheritance services ask you to trust a third party with your keys. That defeats the point of self-custody.

deny.sh works differently. Your encrypted control file is released automatically if you stop checking in. The file itself is deniably encrypted, so even the inheritance mechanism doesn't expose what's really inside.

How it works.

1

Encrypt your seed phrase with a decoy.

Use deny.sh to create a deniable backup. One password shows a dust wallet. The other shows your real holdings. The ciphertext is identical either way.

2

Set a check-in schedule.

Every 30 days, 60 days, 90 days. Whatever fits your life. You get an email before each deadline. One click resets the timer.

3

Name your recipients.

Add the people who should receive your control file. They don't know the switch exists until it triggers. No advance disclosure. No awkward conversations.

4

If you stop checking in, they receive instructions.

After the grace period, your recipients get the encrypted control file and decryption instructions. They still need the password you shared with them separately. Two-factor by design.

5

Combine with Shamir splitting for extra safety.

Split your control file into 3-of-5 shares across recipients. No single person can access your wallet alone. Requires coordination, prevents rogue actors.

FAQ.

What if deny.sh shuts down?

All encryption is client-side. Your files work offline with the open-source CLI. Export your control files as a backup. The switch check-in is the only server feature.

Which wallets/chains are supported?

deny.sh is chain-agnostic. It encrypts any text: seed phrases, private keys, recovery codes, for any blockchain.

Can I update my beneficiaries?

Yes. Log in to manage recipients, update control files, or change check-in schedules at any time.

How is this different from a lawyer or will?

A will is public record after probate. deny.sh keeps everything encrypted and private. No lawyers, no courts, no delays.
