Runes Card

Send value, Not just words

Comment

Inspiration

Sending crypto is quick but when it comes to gifting, it can be a bit tricky. We wanted to transform on-chain gifting into something that feels personal, engaging, and enjoyable. Imagine being able to send value just like you would a greeting card, all while being secured by blockchain technology and powered by Starknet. That’s the inspiration behind Runescard, a blend of magic, privacy, and digital value.

What it does

Runescard lets users create, share, and redeem crypto-based gift cards on Starknet. 1️⃣ A user enters an amount and a custom redeem code. 2️⃣ A unique link is generated to share with anyone. 3️⃣ The recipient redeems the gift by entering the correct code, the funds go directly to their wallet.

Runescard can be used for giveaways, community airdrops, birthday gifts, team rewards, or even treasure hunts with hidden redeem hints.

How we built it

  • Smart Contract: Written in Cairo for Starknet, handling deposits, hashed codes, and redemptions.
  • Frontend: Built with Next.js + TailwindCSS
  • Hashing Logic: Uses poiseden hashing before storing it on-chain for privacy.
