🌱 Project idea

We've had an idea internally for a while to build a "Community Ledger" where members of our community could pay a fee to inscribe their names/handles and a message in a "ledger" which will live on forever on chain. It could be a fun idea to let our community members leave some kind of legacy (discussed a bit in here).

Your task is to build a basic version of this idea.

Your core smart contract should:

• let users mint an NFT with a name and message prop, representing their "brick" id in the ledger
• charge users in token XYZ to mint a brick (XYZ is a fake/test ERC20 token you will need to deploy)
• charge users on an increasing scale - the first mint should cost 10 XYZ and subsequent mints should increase in cost by 3%
• be upgradeable (TransparentUpgradeableProxy)
• be verified on Kovan explorer

Your frontend (React mandatory, Typescript optional) should:

• display minted bricks, with id numbers, names and messages
• allow users to mint a brick (this will require an erc20 approve tx on XYZ and a mint tx)
• display 1) number of total bricks, 2) amount of XYZ in the contract, 3) current price for a brick
• be practical, but well designed with a bit of flourish

📦 Basic project setup
