Brain Playing Radio K-Fuck All Day Long

Can't turn off radio station in my head so downloaded Binaural Beats APKs from the following.
https://binaural-beats.en.uptodown.com/android/download https://apkgit.com/download/com.binauralbeats.freebooster_1.1_free I needed to do this in order to sideload the app to my Kindle Fire HD 6 (4th generation)

Successfully minted NFT to Ethereum Ropsten Network

Using only my linux laptop, I wanted to send an NFT to the Ethereum block chain in order to better understand the process. After checking out several on-line tutorials and failing, I went straight to the source and followed the steps in the following web pages:

1. https://ethereum.org/en/developers/tutorials/how-to-write-and-deploy-an-nft/

2. https://ethereum.org/en/developers/tutorials/how-to-mint-an-nft/

3. https://ethereum.org/en/developers/tutorials/how-to-view-nft-in-metamask/

My previous attempts may have failed because there were too many steps including creating a web app on my laptop, starting localhost http://localhost:3000/, putting the NFT MetaData file at http://localhost:3000/api/erc721/, and then making that file available to the internet using ngrok. Somewhere in there, I am sure there was a typo or a piece missing.

The Ethereum tutorials uploaded the actual NFT image and the NFT meta data to Pinata so there was no need to open up my laptop to the internet. Moreover since I am not creating a production ready NFT, I used my own website at http://spideronfire.com to store the actual image and the meta data

Essentially this is what happens:

Create a smart contract

Make it Ethereum compliant with OpenZeppelin, Hardat and ethers

Connect to Ethereum through the Alchemy Node

Send the smart contract to the Alchemy node through your MetaMask wallet

Wait for Alchemy to validate the transaction

Get the contract address from Alchemy or https://ropsten.etherscan.io/

Mint the NFT using the contract address and a meta data file

The meta data file has a url to the actual image file

The following is a dump of the steps that I took so I can refer back to them after I forget what I did 5 minutes from now.

1. Sign into Alchemy with google
https://dashboard.alchemyapi.io/apps/d8wedo96vjsesxnw
2. MetaMask Chrome extension connected to Ropsten Network
Wallet funded with fake wei
3. mkdir nft-project2
4. cd nft-project2 and open terminal
5. mya55@mya55:~/nft-project2$ npm init
6. mya55@mya55:~/nft-project2$ npm install --save-dev hardhat
7. mya55@mya55:~/nft-project2$ npx hardhat
8. Select “create an empty hardhat.config.js”:
9. mya55@mya55:~/nft-project2$ mkdir contracts
10. mya55@mya55:~/nft-project2$ mkdir scripts
11. Create contracts/MyNFT.sol and paste code
12. remove the word Ownable on line 10 and onlyOwner on line 17 ?
13. constructor() ERC721("SpiFiGen", "SFG")
14. mya55@mya55:~/nft-project2/contracts$ npm install @openzeppelin/contracts
15. mya55@mya55:~/nft-project2$ npm install dotenv --save
16. create .env file in /nft-project2/
17. Populate with Alchemy and MetaMask keys
18. /nft-project2$ npm install --save-dev @nomiclabs/hardhat-ethers ethers@^5.0.0
19. UPDATE HARDHAT.CONFIG.JS
20. mya55@mya55:~/nft-project2$ npx hardhat compile
21. Create /scripts/deploy.js
22. mya55@mya55:~/nft-project2$ npx hardhat --network ropsten run scripts/deploy.js
23. Compiled 1 Solidity file successfully
Contract deployed to address: 0x157FCaD0869E00E1412C3af5C6AC21f7D22c8783
24. https://ropsten.etherscan.io/
25. END: https://ethereum.org/en/developers/tutorials/how-to-write-and-deploy-an-nft/
26. Start: https://ethereum.org/en/developers/tutorials/how-to-mint-an-nft/
27. mya55@mya55:~/nft-project2$ npm install @alch/alchemy-web3
28. /scripts/ CREATE A MINT-NFT.JS FILE
29. Code with ABI file location and contract address from etherscan.io
30. contract: 0x157fcad0869e00e1412c3af5c6ac21f7d22c8783
31. mintNFT("https://spideronfire.com/SpiFiGen/metadata.js")
instead of IPFS Pinata upload
32. node scripts/mint-nft.js
33. The hash of your transaction is:
0x86c7937597433eb4f9de36902081baf6849e2bbd6f0952730d8423a34ac360a2
Check Alchemy's Mempool to view the status of your transaction!
34. https://dashboard.alchemyapi.io/mempool
35. Start https://ethereum.org/en/developers/tutorials/how-to-view-nft-in-metamask/
36. Open MetaMask Android. Ropsten Network. Import NFT from contract address
37. It WORKED!
