Keep earning. Transfer when it matters.
Create a non-custodial plan that keeps your USD earning until a time-lock or inactivity trigger transfers it to your beneficiary.
Non-custodial. On-chain. Keeps earning until transfer.
Audited, widely used primitives for custody (Safe), standardized yield (ERC-4626), lending (Aave v3), low-fee settlement (Base), reliable execution (Chainlink), and email/social sign-in (Privy).
Why Mr Haven?
We never take custody of your funds.
Time-locks and inactivity checks run on-chain. When your conditions are met, transfer happens automatically and can be verified.
Send to any wallet—or use email so your beneficiary can claim later with a code.
How It Works
Sign in
Sign in with email or social. We show your smart account address and create it when you take your first on-chain step—no seed phrases.
Fund once
Deposit USD. Your balance continues to earn yield while it waits.
Choose a trigger
Pick a date (time-lock) or set an inactivity window.
Automatic transfer
When the trigger hits, your plan transfers the position to your beneficiary's wallet. If you used email, they can use their claim code any time.
Simple, transparent pricing
(0.25% at funding, 0.55% at execution)
(0.25% at funding, 0.75% at execution)
Fees are collected from the position; you never send a separate payment.
Cancel before execution? Only the funding fee applies.
