Onchain inheritanceSet up once. Check in when it suits you.
Set up
Choose heirs, their shares and the assets each one receives. Perpetua is approved for those assets only.
Check in
One small signature resets the timer. Choose 30, 90, 180, 365 days.
If you stop
Miss a deadline and a 7-day grace period begins. Reminders arrive before both.
Heirs receive
When grace ends, the switch executes and each heir receives their share directly.
Your assets never leave your wallet. Perpetua holds a permission, not your property, and the program can use it only after you stop checking in.
A permission, not a deposit.
- Delegation, not transfer
- You approve the Perpetua program as delegate on the token accounts you choose, for the amounts you choose. The tokens stay in your wallet.
- SOL stays yours
- SOL you set aside is wrapped into a reserve account that you own, at an address no trading app touches. It shows in your wallet as wrapped SOL.
- Undo at any time
- Cancel revokes every approval and returns the reserve to plain SOL in one transaction. Only the program can use the approvals, and only after execution starts.
A check-in is one signature.
It costs only the network fee and tells the program you are here. Reminders reach you by email or Telegram well before a deadline.
Check-in interval
- Check in by
- February 6, 2027
- If you miss it, executable after
- February 13, 2027
Each check-in, and any change you sign, starts the interval again from that moment.
A last letter, sealed until it matters.
Write a private message for each heir. It is encrypted in your browser and opens only for that heir's wallet, only after the switch executes. Perpetua never sees the words.
How letters are sealedBuilt to be checked, not trusted.

Questions
Does Perpetua ever hold my assets?
No. You approve the Perpetua program as a delegate on the accounts you choose. Your tokens and the SOL you set aside stay in accounts you own until the switch executes. Only then does the program move them, straight to your heirs.
What happens if I miss a check-in?
Nothing moves at the deadline. A 7-day grace period begins, and you can still check in at any point until execution starts. Reminders go out 30, 7, 1 days before the deadline and again during grace.
Can I change my mind?
Yes. You can edit heirs, shares, assets and the interval, pause the switch, or cancel it. Cancelling revokes every approval and unwraps your SOL reserve in one transaction. Any change you sign also counts as a check-in.
What do my heirs need to do?
Nothing to receive assets. Execution sends each heir their share and opens their token accounts if they do not have them yet. To read a letter, an heir connects the wallet you named and signs a message.
Who runs execution?
Our keeper checks every switch on a schedule and runs execution when it is due. Execution is also permissionless, so anyone can run it and no single party, including us, can stop it.
What does it cost?
A Free-tier switch costs 0.05 SOL to set up. Check-ins cost only the network fee. When a switch executes, the program takes 0.5% of the assets delivered into the treasury. Holder and Patron tiers have no setup fee.
