The flow
Three signatures.
One unforgettable moment.
02
Friends drop wishes
Each contributor writes a personal wish and signs it directly into the Sui plan. Adding a wish is free — friends only pay minimal network gas.
03
Reveal together
On the big day, open the plan link and watch every wish bloom in a single shared canvas. Nothing to download. Nothing to lose.
Tech stack
No servers. No vendor lock-in. Just open protocols.
S
Sui Object Model
Each plan is a shared on-chain object. Every contribution is a signed transaction emitted as an event — auditable, immutable, and instantly readable from any RPC.
W
Walrus Storage
AI-generated images are uploaded to Walrus testnet as decentralized blobs. The blob ID is what we store on Sui — so the picture outlives any server.
