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.
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.
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
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.
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.
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.
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. trellis-two-smoky.vercel.app
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. #Solana #BuildOnSolana
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.
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.
