How Daycade Works

Imagine you have a list of ultra-important passwords. If you have an accident tomorrow and can no longer log in, your family is locked out of everything. Daycade is an automatic digital safe: if you disappear or are no longer around, it opens by itself for the people you chose. As long as you are active, it stays locked tight. Even Daycade itself cannot open it.

The full process in 7 simple steps

1

You fill out a form

You open the Daycade website and enter what you want to protect (passwords, notes, files), who should receive access (your family, your lawyer…), and when (for example: if I give no sign of life for 1 year, open the safe).

  • You choose beneficiaries by email address.
  • You set an inactivity delay (1 month, 1 year…).
  • You can review everything before confirming.
2

Your browser turns your data into unreadable encrypted data

Before your passwords and notes leave your computer, your own browser scrambles them using an ultra-complex secret code. Even if someone intercepts the data along the way, they will only see meaningless characters: x7$Kp!mQ3rLz… They cannot do anything with it.

  • Encryption happens on your device, before anything is uploaded.
  • Only the encrypted (unreadable) content leaves your computer.
  • Nobody can read your information while it is being transferred.
Tool used : AES-256, the name of the secret code. The same used by banks, governments, and the military. The '256' means the code is so long that a computer would need billions of billions of years to guess it.

The encrypted data is spread across thousands of computers worldwide

The encrypted data is not stored on one big computer (which could crash or get hacked). It is split and spread across thousands of independent machines all over the world. To reconstruct your data, you need all the pieces. There is no single weak link to attack.

  • No central server can be shut down to make your data disappear.
  • Daycade gets a receipt number (an identifier) to find your data later.
  • Storage is automatically renewed when needed.
Tool used : Walrus, a decentralized storage network. Think of it as a giant USB drive spread across thousands of computers around the world.

Your rules are engraved in the blockchain, forever

A blockchain is like a big public ledger that anyone can read, but no one can modify or erase, not even Daycade's creators. In this ledger, a smart contract is written: an automatic contract that enforces your rules without needing a human.

  • The contract contains: your identity, your beneficiaries, your delay, and the address of your encrypted data.
  • These rules are immutable, impossible to change without your approval.
  • Everything triggers automatically when the time comes, with no button to press.
Tool used : Sui Blockchain, think of it as a town hall that can never close, burn down, or be corrupted. It officially records the rules of your safe.
5

You regularly confirm 'I'm still here'

The countdown is running. Daycade sends you reminder emails at key moments. You just click a button to say 'I am still here'. The counter resets. Your beneficiaries see nothing.

  • Reminders are sent at 50%, 75%, 90%, and 95% of the delay progress.
  • If you confirm, the safe stays locked for your beneficiaries.
  • If you do not reply, the countdown continues until the safe opens automatically.
6

If you stop responding, the safe opens automatically

If the delay is reached without any response from you, the smart contract on the blockchain triggers on its own. Your beneficiaries receive an email with a secure link to access your decrypted data.

  • Access is available for a maximum of 7 days, then disappears permanently.
  • A successful recovery ends the confirmation cycle for that safe.
  • Daycade cannot extend the 7-day window after the safe opens.

Background programs keep everything reliable

All the time, automatic programs check that your data is properly stored on Walrus, send reminders at the right moments, and make sure emails are delivered to your beneficiaries.

  • Emails go through external services and can sometimes end up in spam.
  • Network outages may delay some actions.
  • Help contact: contact@daycade.com

What even Daycade cannot do

Daycade can never read your passwords or notes. Here is why: your data is turned into an unreadable code on your own device before being sent anywhere. Daycade only ever receives that unreadable code and never has the key to decode it. Your rules (beneficiaries, delay) are recorded on a public blockchain, not stored on Daycade's servers. Your encrypted data lives on the Walrus network, not with Daycade. You do not need to trust a company. Everything relies on mathematics and automatic code that no one controls.

How do you log in to the site?

You use your Google account (the 'Sign in with Google' button). The Google zkLogin technology lets you prove it is really you without Google or Daycade seeing your private information. It is like showing your ID card at the entrance of a club: the bouncer knows you meet the requirement, but does not write down your name or address.

Tool used : Google zkLogin, secure sign-in via your Google account, without sharing your private data.

Important note about emails

Emails are handled by external providers. Even with retries, a message can be delayed, filtered, or blocked by the recipient's mailbox settings.
