Secure crypto inheritance without middlemen.
Your USDC stays in a vault only you control. You choose who it goes to, how much can leave each day, and who has to sign off on more.
Runs on Solana Devnet. Not audited yet, so use test funds.
- New names wait 48 hours before they can be paid
- 100 USDC can leave per day
- Above that, a guardian signs
Setting up takes four steps
- 1
Create your vault
Connect Phantom on Devnet and create the vault. The keys stay in your wallet. Trellis never holds your funds.
- 2
Name your family
Add up to 10 people by wallet address. Each new name waits 48 hours before it can be paid, so a stolen key can't add a stranger and pay them in one go.
- 3
Fund it with USDC
Deposit from your wallet. Up to 100 USDC can leave per day, and the count resets at 00:00 UTC.
- 4
Add a guardian
Pick someone you trust to sign anything above the daily limit. The owner can never be their own guardian.
What the program enforces
These aren't settings in an app. They're checks inside the Solana program, so nobody can skip them, including us.

A kiosk for the relative who'd never touch a seed phrase
A touchscreen at home with one job: show the balance and send to approved family. It pairs with a relative's phone through a code on screen, and every transfer follows the same limits and guardian rules as the vault.

Questions
What happens if I lose my key?
Your guardians can start a recovery that hands ownership to a new key. It only completes after a 72-hour wait, so you can cancel it if you still have access.
What does it cost to run?
Creating a vault pays Solana rent once, about 0.011 SOL. After that you pay normal network fees per transaction.
Who can move the money?
Only you, and only to people on your list. Anything above the daily limit waits for a guardian to sign.
Is the contract audited?
Not yet. Trellis runs on Solana Devnet as an unaudited prototype. Use test funds only.
