A scammer talks grandma into adding their address. Then they wait 48 hours.

Every new name in a Trellis vault waits two days before it can be paid. Enough time for the family to notice.

[Trellis @TrellisVault]

A crypto wallet grandma can actually use.

Big black-on-white buttons, no seed phrase, a confirm step before every send. Designed to WCAG 2.2 AAA.

And her own wallet has no limit: her money, her control.

[Trellis @TrellisVault]

3 apps. 1 Solana program. 350 tests.

Kiosk in Rust + Slint, family app in Tauri, dashboard in Next.js, all on one Anchor program. 45 tests run the compiled program in a local Solana VM.

[Trellis @TrellisVault]

Update: Trellis is on the road to mainnet 🛣️

Our family vault program is feature-complete on Devnet: 13 instructions, 350 tests.

Next: a security audit. No real funds until every rule is verified.

We’re building Trellis for the @ColosseumOrg Frontier Hackathon. 🛠️

Web3 excludes older adults and leaves them vulnerable to scams. We're fixing that with a single-purpose hardware kiosk for seniors, paired with a Next.js family management portal.

🔒 Closed address books ⏳ 48h new-contact cooldowns 📱 Zero seed phrases
Follow along as we build the physical terminal and the Anchor smart contracts over the next 4 weeks. #Solana #BuildInPublic #Superteam

[Trellis @TrellisVault]

Older parents can't safely use crypto: one wrong tap and it's gone.
So families keep them out, or hold their keys with no limits.
We built Trellis: secure crypto inheritance without middlemen, on @solana.

[Trellis @TrellisVault]

Grandma gets a kiosk with big buttons. No seed phrase, no browser, no dApps.

She can only pay people her family approved, and every new name waits 48 hours, so a scammer who sneaks in gets nothing in time.

[Trellis @TrellisVault]

The family uses a phone app that pairs with the kiosk over Bluetooth.

The shared family pool has a daily limit. Anything above it becomes a request a guardian must sign, and owners can't approve their own.

[Trellis @TrellisVault]

A family vault with a daily limit nobody can skip.

Not a setting in an app: a check inside our Solana program. Above the limit, the payment becomes a request instead.

What if your family's crypto had guardrails?

Trellis is policy-based self-custody on Solana: an allow-list of recipients, a 48-hour hold on new ones, and guardian approval for large transfers. Enforced on-chain.

[Trellis @TrellisVault]

None of this is an app setting. It's enforced by our Anchor program on Solana, tested with 350 Rust tests.

The kiosk is designed to WCAG 2.2 AAA: black on white, 60px buttons, a confirm step before every send.
