A savings plan that can run without you
Set your rules. If you stop checking in or a set date arrives, the vault hands off your money automatically.
Time vault basics
- A non-custodial vault on Base where you choose who gets paid and when.
- While you're active, nothing moves unless you change it.
- When your rules trigger, the vault executes your plan automatically.
Why people use it
Backup for self-custody
Assets stay accessible to your chosen people, not locked forever.
Automatic handoff
Smart contracts execute your plan when conditions are met.
Savings that can keep working
Funds can earn yield while waiting via integrated vaults.
Who it's for
Self-custody users who want a backup plan. Recipients only need an email.
Best for people who:
Want a backup plan for people they care about
Prefer rules-based automation over ad-hoc transfers
Want on-chain security instead of scattered notes
Not ideal if:
• You want FDIC insurance or guaranteed returns.
• You're not comfortable with self-custody or Web3 wallets.

Under the hood
How the system keeps your plan rule-based and non-custodial.
Non-custodial vaults
You control the vault and its rules. Mr Haven cannot access or withdraw your funds. Only the smart contract logic you approved can move them.
Time-based triggers
Smart contracts on Base run your plan automatically when your time or inactivity conditions are met.
On-chain transparency
All vault activity is recorded on the Base L2 blockchain, so you can independently verify deposits, yield, and transfers.
