The problem

Crypto wealth disappears
when wallets do.

When someone dies or loses access to their wallet, there's no system to pass it on. No bank to call. No recovery process. The assets are simply gone — forever. SolWill changes that.

How it works

Four steps.
Zero trust required.

Every rule is encoded in an Anchor smart contract deployed on Solana. No admin. No multisig backdoor. No override.

01
Connect your wallet
Connect any Solana wallet. SolWill reads your assets automatically. No sign-up, no email, no password.
02
Name your heirs
Add heir wallet addresses and set percentage splits. All stored in a PDA on-chain. Only the program can enforce it.
03
Check in regularly
One tap every 30–180 days resets the clock. Miss the window and the smart contract automatically triggers.
04
Heirs claim instantly
Any heir visits the app, connects their registered wallet, and claims their exact share — SOL, tokens, and NFTs — in one transaction.

On-chain state machine

Every transition enforced
by the program.

Draft
Will created, vault empty
→
Active
Vault funded, clock running
→
Active · checked in
Clock reset by owner tx
→
Triggered
Deadline missed · anyone can fire
→
Settled
All shares claimed by heirs

The trigger instruction is permissionless — anyone can call it after the deadline, verified entirely by on-chain clock. No oracle, no admin, no human in the loop.

Features

Built for the real world,
enforced on-chain.

Multi-asset vault
Lock SOL, any SPL token, and NFTs (including compressed NFTs) into a single program-controlled vault. All transferred atomically to heirs.
Flexible heir splits
Assign exact percentage splits in basis points. Up to 10 heirs per will. Share calculation and distribution is done entirely in-program.
Configurable intervals
Choose 30, 90, or 180-day check-in windows. Check-in from any wallet client — just sign the instruction from your owner key.
Permissionless trigger
After expiry, anyone can call the trigger instruction. The program validates the deadline against the on-chain clock — no trusted party needed.
Helius webhook alerts
Helius monitors on-chain events and pushes real-time notifications when a will is triggered or an heir claims their share.
Cancellable anytime
Owner can cancel the will and withdraw all vault assets at any time while the will is Active. Full custody, always.

The safest will
is one that runs itself.
