海外TECH	DEV Community	Creating an NFT on Solana with Metaplex Candy Machine.	https://dev.to/devindxdeveloper/creating-an-nft-on-solana-with-metaplex-candy-machine-4agp	Creating an NFT on Solana with Metaplex Candy Machine Guide OveriewAfter what felt like walking through a mine field trying to figure out how to create my own NFT on Solana with the current guides I decided to put together a guide myself in a very beginner friendly fashion I won t be taking a deeper dive into the specifics of how everything works but rather help people with zero knowledge of rust obtain a general understanding on how to create their very own NFT on Solana with the help of Metaplex candy machine and a web starter kit Note I used Ubuntu Wayland for it Some things may vary depending on the operating system you are running What is a Metaplex Candy Machine Metaplex is a command line tool that interacts with the candy machine program In this guide we will use it to Upload your images along with their metadata to arweave then register them on the Solana blockchain Verify that the state of your candy machine is valid and complete Mint individual tokens Candy Machine is a system that manages fair mints •The minting process starts and finishes at the same time for everyone •It won t accept your funds if there are no more NFTs to sell PrerequisitesNodeJS version SolanaCLIMetaplex CLIPhantom WalletIf you have a different version of Node installed on your system you can use nvm which allows you to quickly install and use different versions of node via the command line Getting Started Installing The SolanaCLISolana already has really well made guides on installing and using the Solana command line •Install Solana Command Line Tools Using DevnetDevnet is really useful for developers to test out their programs and applications You can set your default Solana url to devnet using solana config set url Now let s create a devnet wallet solana keygen new outfile config solana devnet jsonRemember to store your seed phrase somewhere safe I highly recommend making devnet your default keypair solana config set keypair config solana devnet json Funding The Devnet WalletFirstly let s make sure that we re on devnet by checking the configuration solana config get Output Config File Users dev config solana cli config ymlRPC URL WebSocket URL wss api devnet solana com computed Keypair Path Users dev config solana devnet jsonCommitment confirmedNow let s fund that wallet Firstly We check the balance of our current wallet solana balance Output SOLThen we airdrop the amount of SOL to our wallet Remember the amount is capped to SOL solana airdrop OutputRequesting airdrop of Signature Transaction Signature SOLNow Let s check our balance to confirm the airdrop was successful solana balance Output SOL This can vary depending on the balance you initially had In case you re confused by any of the above steps you can check the manuals to get a better understanding by running solana help config solana help balance solana help airdrop Configuring Phantom WalletAfter setting up your phantom wallet we can link our newly created devnet wallet above to phantom To do so first we need to open its settings click on Change Network and select DevnetNow we need to obtain the devnet wallet private key To obtain that open your terminal and cat to view the contents of the keypair json file cat config solana devnet json Output Now copy the output you received and open phantom wallet Click on the top left navigation menu and click on Add Connect Wallet and then click on Import Private Key and give it a suitable name and paste the contents we copied before in the Private Key field You should be able to see SOL in your wallet Running Candy Machine CLIPlease ensure that you have node and yarn installed before proceeding Also install ts node by running npm install g ts nodeNow let s clone the metaplex project into the location of your choice git clone cd metaplex js yarn install amp amp yarn bootstrap amp amp yarn buildTo run the command line utility ts node metaplex js packages cli src candy machine cli ts helpUsage candy machine cli options command Options V version output the version number h help display help for commandCommands upload options lt directory gt verify options verify price options create candy machine options update candy machine options mint one token options sign options sign candy machine metadata options help command display help for command Organizing amp Uploading Your AssetsFor this guide we will be using pre made assets which you can download by clicking here courtesy of solana candy factoryPlace this assets folder in a suitable location Here is how you should organize your NFT files to upload ls assets sort n json png json png json png json png You can notice that these files come in numerical pairs that is png and json are the two halves of the NFT The png file is the art work and the json file contains the metadata The directory name assets does not matter You can go with anything you like Validating Your AssetsThis may feel tedious but it s just as important Checkout the the manual on carrying this out at Uploading Your Project AssetsNow that we have the funds assets all organized and vaidated we can proceed with the fun stuff We will proceed with uploading our assets with the CLI Remember our assets are located at metaplex js packages cli example assets ts node metaplex js packages cli src candy machine cli ts upload assets env devnet keypair config solana devnet json OutputProcessing file Processing file Processing file Processing file DoneBy uploading it sends the files to Arweave and also registers those files with your candy machine Both Arweave and Solana are initialized after a successful run Validating Your Candy MachineYou can confirm the health and status of your on chain assets using ts node metaplex js packages cli src candy machine cli ts verify env devnet keypair config solana devnet json Output Looking at key Name redacted name with redacted tx id checked outLooking at key Name redacted name with redacted tx id checked outLooking at key Name redacted name with redacted tx id checked outLooking at key Name redacted name with redacted tx id checked out Starting Your Candy MachineAfter verifying that our assets are good to go we can finally start the candy machine ts node metaplex js packages cli src candy machine cli ts create candy machine env devnet keypair config solana devnet json Updating Your Candy MachineWe can modify our candy machine details to include a start date and or price etc ts node metaplex js packages cli src candy machine cli ts update candy machine env devnet keypair config solana devnet json price date Oct GMT Minting Our NFTTo mint our NFT we can use mint one token like so ts node metaplex js packages cli src candy machine cli ts mint one token env devnet keypair config solana devnet jsonIf all goes well you can now open your phantom wallet open the collectibles page It s beside the symbol on the bottom and voila Your newly minted NFT will be there Setting Up The Web Starter KitNow that we ve successfully minted an NFT into our wallet let s make a web application to carry out the mint instead Note This project is very new and could cause some issues if it does then please report it on github The goal of the project is for you to be able to configure it and customize it to your liking Fork the project and then clone it to your desired location Link Now we need to build the project cd candy machine mintyarn installyarn buildThis is where things get a little bit complicated When we uploaded our NFTs a cache file was created in the same directory as our assets directory However this cache folder is hidden If you re on ubuntu use ctrl h to display hidden files Once you have discovered that folder open it and you ll find devnet temp file Open it in your IDE and you ll see the following program uuid Chxxx config Chxxx items link name TEST onChain true link name TEST onChain true link name TEST onChain true link name TEST onChain true link name TEST onChain true link name TEST onChain true env devnet cacheName temp authority xJxxxx candyMachineAddress Wmxxxx startDate We re going to need all this data when we run our web application to mint Configuring Candy Machine MintOpen up the candy machine mint folder where you will find a file called env example The file is usually hidden use ctrl h to display hidden files Rename it to env and then open it to edit the following details REACT APP CANDY MACHINE CONFIG PLACEHOLDER This is the program config key from our cache devnet temp file REACT APP CANDY MACHINE ID PLACEHOLDER This is the candyMachineAddress from our cache devnet temp file REACT APP TREASURY ADDRESS PLACEHOLDER This the Solana address that receives the funds gathered during the minting process You can set this to your devnet wallet address REACT APP CANDY START DATE PLACEHOLDER This is the startDate key from our cache devnet temp file Note If you cannot find it use update candy machine as mentioned above as you may have missed out on mentioning the date REACT APP SOLANA NETWORK devnetThis identifies the Solana network you want to connect to Options are devnet testnet and mainnet REACT APP SOLANA RPC HOST This identifies the RPC server your web app will access the Solana network through Starting The Web ApplicationOpen your terminal and navigate to the candy machine mint directory and start the react app by using yarn startOnce you see Compiled Successfully in your terminal Open http localhost to view it in the browser You can now proceed with connecting your wallet and clicking on the mint button After clicking on the mint button you can check the collectibles page on your phantom wallet and you ll see your newly minted NFT That s all I will be covering in this guide If you encounter any issues comment down below and I ll try to help Other
