🔎 Project Overview

Frontend (Static Website) (./src)

The front end is built by Next.js, which uses FCL (Flow Client Library) to interact with wallets and smart contracts; there is no back-end API.

Smart Contracts (./cadence)

I designed and implemented a generic contracts to create digital message cards.

• MessageCard.cdc

  • The main contract for creating message card templates and messages.
  • Mainnet: https://www.flowdiver.io/contract/A.f38fadaba79009cc.MessageCard

• MessageCardRenderers.cdc

  • This is the implementation of the renderer created to make the template for this ema. Users can also create their own renderer.
  • Mainnet: https://www.flowdiver.io/contract/A.f38fadaba79009cc.MessageCardRenderers

• EmaShowcase.cdc

  • A contract made so that you can get a list of everyone's emas. It is independent from the MessageCard as a separate contract.
