nft-demo's Introduction

NFT Demo

This project creates a smart contract and then deploys it to Rinkeby public testnet. NFT's can then be minted by sending transaction to the deployed smart contract.

Find the NFT's on Opensea testnet:

https://testnets.opensea.io/assets/0x1e9930Bc5f39dE0515BeC52612bc4510F7B236C0/1

Follow the Youtube tutorial here:

Dependencies:

NodeJS
https://nodejs.org/en/download/
Ganache UI
https://www.trufflesuite.com/ganache

(Ganache UI is not required in case you want to work with ganache-cli)

Usage:

Clone the repo and run npm install.
git clone https://github.com/neha01/nft-demo.git && cd nft-demo && npm install
Put image file that you want to convert into an NFT under assets folder.
Create a account in Pinata (https://www.pinata.cloud/) and create an API Key.
Click on top right profile picture -> API Keys -> New Key
Note down The API Key and API Key Secret and update in .env file.
Update the name of your image file in assets folder.
Update filePath with your image filepath.
Run node scripts/runScript command.
This will call Pinata API's and will upload file to IPFS and a new file will be created in data folder ipfsHash.json and the Pinata response containing the ipfsHash will be populated in that file.
Now create a metadata.json file with the details about your NFT. For Reference checkout data/metadata.json file . Update filePath with your metadata filepath. Again Run node scripts/runScript command. This will call Pinata API's and will upload metadata file to IPFS and the Pinata response containing the ipfsHash will be again populated in ipfsHash.json file.
Install latest solidity version by running npm install solc and Dont forget to update this solidity version in truffle-config.
Update Rinkeby test network details in truffle-config.js .
Update your account mnemonic in .env file.
Now run truffle console --network rinkeby to connect to Rinkeby Public test network.
Run migrate command to deploy the contract on Rinkeby testnet.
Run let art = await ArtCollectible.deployed().
Run await art.claimItem('https://ipfs.io/ipfs/QmREBUVuoeX39eB9KiQjp25RFr2dhYF6zawpYXq1UPJXEz')
Pass the correct metadata file IPFS address to claimItem.
Run art.address to get contract address.
Checkout your NFT on https://testnets.opensea.io/assets/contract_address/tokenId.
You can also verify your metadata using on https://rinkeby-api.opensea.io/asset/contract_address/tokenId/validate
eg: https://rinkeby-api.opensea.io/asset/0x1e9930Bc5f39dE0515BeC52612bc4510F7B236C0/1/validate

Migrate does not work due to the transaction not mined within 750 seconds

Hello Neha,

The following command does not work on the mainnet :

npx truffle migrate --network matic

Here is my .env file :

PINATA_API_KEY="*"
PINATA_API_SECRET="*"
PINATA_ENDPOINT="https://api.pinata.cloud/pinning/pinFileToIPFS"
MNEMONIC="*"
CLIENT_URL="https://polygon-rpc.com/"
CONTRACT_ADDRESS="YOUR_DEPLOYED_CONTRACT_ADDRESS"

The transaction are visible on polygonscan but I get an error when I reach 750 seconds with the following error :

Error:  *** Deployment Failed ***
"Migrations" -- Transaction was not mined within 750 seconds, please make sure your transaction was properly sent. Be aware that it might still be mined!.

Here is a transaction example https://polygonscan.com/tx/0x9fdb1d9418ed6b430f3e54255f05b92801e80cf28dc2612dcaa44c53b19ddbe5

Don't we need to set gasPrice or gas in the matic provider ?

Thanks,

When is metadata.json read ?

Hi Neha,

I found your project on youtube and was not able to see where and how the metadata.json file was read by your application.

Is the api of pinata accept either an image file or a json file ? Could make sense

Thanks

i ma getting an error after i run 'node scripts/runScript.js'

Pinning to IPFS failing

Hi Neha,

I get a similar error to the one mentioned earlier -
Error occured while storing data to file Error: Configuration property "ipfsFile.location" is not defined
at Config.get (D:\GitHub\yoriverse\node_modules\config\lib\config.js:182:11)
at storeDataToFile (D:\GitHub\yoriverse\scripts\ipfsHelper.js:10:50)

at processTicksAndRejections (internal/process/task_queues.js:95:5)
Successfully added IPFS response to json file

Prior to this error I also get the output
data: {
IpfsHash: 'QmbAVkKcEiLSjXUYpYuTKipJYZmoVgeV85PahG6Fp1D5Sc',
PinSize: 224676,
Timestamp: '2022-05-22T12:00:50.187Z',
isDuplicate: true
}

But no data folder is being created.

I tried setting the NODE_ENV to dev. Anything else I am missing?
