Running Steps

1. Setup
2. Add Taker Address to DB(SQLite)
3. Upload JSON Metadata(e.g. Arweave)
4. Create Merkle Tree
5. Mint cNFT

1. Setup

Install Packages in umi directory

% cd umi
% mv .env.example .env
% npm i

Create .env in cNFT directory

% cd ..
% cd cNFT

Install Packages and init tables in cNFT directory

% npm i
% npx prisma migrate dev --name init

2. Add Taker Address to DB(SQLite)

If you want to test minting, generate random taker address. You can modify taker address in takerAddress.csv.

% ts-node src/generateRandomPublicKey.ts > src/assets/takerAddress.csv

Add the taker address to the DB.

% ts-node src/addTakerAddressToDB.ts

3. Upload JSON Metadata(e.g. Arweave)

% cd ..
% cd umi
% ts-node src/irysUploader.ts

4. Create Merkle Tree

% cd ..
% cd cNFT
% ts-node src/createMerkleTree.ts

Write your Merkle Tree to src/mintWithoutCollection.ts.

5. Mint cNFT

% ts-node src/mintWithoutCollection.ts

You can stop it at anytime with command+C.

Note

Get All Taker Address in DB

% ts-node src/findAllTakers.ts
