FireFly to Launch an NFT Collection

[FahimDev]

Using Hyperledger FireFly to Launch an NFT Collection on Public Chains

Key Points:

• Setup FireFly
• Connect FireFly on the Public Chain
• Deploy and Configure a Custom Token Connect With FireFly
• Upload NFT assets with FireFly
• Mint NFTs on a Public Chain with FireFly

FireFly keeps its own SQL Database which keeps all Evens of Blockchain operations.

Prerequsites

• Ethereum Wallet App
• Docker
• Docker Compose
• OpenSSL

Alpha Wallet is an open-source project. Easy to connect with Test Nets and can show Media Data for ERC721 Tokens.

In this card we will cover:

• Run FireFly on our local machines
• Use FireFly to deploy an ERC-721 smart contract to the Polygon Mumbai testnet
• Use FireFly to upload an image and metadata.json to public IPFS
• Mint a token with our smart contract
• Transfer that token to a wallet

Extract the binary of FireFly and move it to /usr/bin/local:

sudo tar -zxf ~/Downloads/firefly-cli_*.tar.gz -C /usr/local/bin ff && rm ~/Downloads/firefly-cli_*.tar.gz

ff init ethereum polygon 1 \

--multiparty=false \

--ipfs-mode public \

-n remote-rpc \

--remote-node-url "https://polygon-mumbai.g.alchemy.com/v2/PROTECTED" \

--chain-id 80001  \

--connector-config evmconnect.yml \

--node-name "TrustChain-Node" \

--org-name "TrustChain-Org"

Make sure to add your Remote DB Connection string

Hyperledger Fabric by default holds a Crypto Wallet Address. To get the wallet address the command is given below: ff accounts list project_name | grep address

FireFly also runs a IPFS node locally.

FireFly Important API EndPoints:

• BASE_URL/contracts/deploy

Sample Request: { "contract": "PASTE_BYTECODE_HERE", "definition": PASTE_ABI_HERE, "input": [] } Sample Response: { ... "output": { "contractLocation": { "address": "0xfd403b063ecf959867973a4cf383c48b9a06e19e" }, }, ... }

• BASE_URL/contracts/interfaces/generate

Sample Input Structure: { "input": {"abi": PASTE_ABI_HERE}} This API Endpoint is basically for generating the Request Body for (POST) BASE_URL/contracts/interfaces API

MAKE SURE YOU COPY THE RESPONSE THAT YOU WILL SEND AS A REQUEST IN THE NEXT STEP AS REQUEST BODY

• POST : BASE_URL/contracts/interfaces

  {
  "name": "FILL_IN_A_NAME",
  "version": "FILL_IN_A_VERSION",
  ...
  }

  After generating the Contract Interface with the ABI we will get a Contract Interface ID

Create Custom API for Custom Smart Contracts

POST http://127.0.0.1:5000/api/v1/apis?confirm=true Sample Request Body:

{
  "interface": {
    "id": "3d9d4d16-b548-4f5c-957e-db44e75f6354"
  },
  "location": {
    "address": "0x3431d051d29fbe4884c6ebc1105f7bd606f0ccab"
  },
  "name": "product-twin"
}

Sample Response Body:

{
  "id": "bd4be993-c009-4068-bfbc-02eb12f1611c",
  "namespace": "default",
  "interface": {
    "id": "3d9d4d16-b548-4f5c-957e-db44e75f6354"
  },
  "location": {
    "address": "0x3431d051d29fbe4884c6ebc1105f7bd606f0ccab"
  },
  "name": "product-twin",
  "urls": {
    "openapi": "http://127.0.0.1:5000/api/v1/namespaces/default/apis/product-twin/api/swagger.json",
    "ui": "http://127.0.0.1:5000/api/v1/namespaces/default/apis/product-twin/api"
  }
}

This is how can can call the methods of our Smart Contract form the FireFly API Endpoints.

• POST : BASE_URL/tokens/pools

  {
  "config": {
  "address": "YOUR_DEPLOYED_CONTRACT_ADDRESS",
  "blockNumber": "YOUR_CONTRACT_DEPLOYMENT_BLOCK_NUMBER"
  },
  "interface": {
  "id": "YOUR_INTERFACE_ID"
  },
  "name": "YOUR_TOKEN_NAME",
  "symbol": "YOUR_TOKEN_SYMBOL",
  "type": "nonfungible"
  }

  Token Pool? After using the following API endpoints FireFly will start Tracking the Transactions of these Smart Contracts in its Token Pools.

  Upload Media Data to FireFly Node:

• POST : BASE_URL/data

  This endpoint allows you to upload Image/Media Files to FileFly node. From there we can send these files to IPFS node to use it as our NFT MetaData. This endpoint will return a Blob ID. Make sure you have selected form Type multipart/form-data and You will also need to uncheck the bottom two checkboxes for the metadata and validator fields.

• BASE_URL/{bolob_id}/blob/publish

  This endpoint will take the Blob ID and will return the IPFS cID.

Mint Token with IPFS MetaData:

• BASE_URL/tokens/mint

  .....

• BASE_URL/tokens/transfers

  TokenIndex ?
