What does this repo support?

You can use this repo to deploy your own candy machine UI.

• It supports multiple candy machine groups, but also just using a default group
• It creates a Lookup table for you to allow more active guards at the same time
• The initializer shows you the merkle root for your groups
• The users see NFTs left, start and end countdowns, reasons for not being able to mint and more
• Combining most of these guards is possible since we are lookup tables. For example using allowlist,nftBurn, nftPayment, solPayment, startDate and endDate
• For larger allowlists this UI will automatically split the mint into two transactions to avoid hitting the transaction size limit
• Dynamic Compute Unit calculation to have higher chances to get the mint included into a block
• Priority fees are added. Those are hardcoded to a very small number. As of 15 March 24 all the dynamic solutions are only possibly with specific RPC providers. If you want to have it dynamic you need to implement it yourself.
• It supports most of the existing guards:
  • addressGate
  • allocation
  • allowlist
  • assetBurn - untested currently - test on devnet and provide feedback please!
  • assetBurnMulti - untested currently - test on devnet and provide feedback please!
  • assetMintLimit - untested currently - test on devnet and provide feedback please!
  • assetPayment - untested currently - test on devnet and provide feedback please!
  • assetPaymentMulti - untested currently - test on devnet and provide feedback please!

  • tokenPayment
• Multimint (can be deactivated by adding NEXT_PUBLIC_MULTIMINT=false to .env)

How to use

Prerequisites

• pnpm as package manager - I used 8.1.0
• Your deployed candy machine. If you don't know how to deploy you might want to look into the Developer Hub or the inofficial ts-sugar CLI.
• Access to a RPC with DAS or Metaplex Aura

How to use

1. Clone this repo
2. Run pnpm install
3. copy the .env.example file to a new .env file and fill in the NEXT_PUBLIC_CANDY_MACHINE_ID value. You should have this value after creating your candy machine. Also fill NEXT_PUBLIC_RPC to your RPC URL. It should support Metaplex DAS.
4. Run pnpm run dev
5. Open your browser at http://localhost:3000
6. Connect your wallet which you used to create the candy machine
7. You should see a red Admin Menu button. Click it and then click create LUT
8. Copy the LUT address that you see in the green success box and paste it into the .env file as the value for NEXT_PUBLIC_LUT
9. Add your candy machine groups to the settings.tsx file. E.g. if one of your groups is called WL you should have an entry for it in there, too
10. Deploy your Candy Machine e.g. to Vercel or Cloudflare Pages

Done!

customization

You can customize the UI by changing the code. If you just want to modify some values you can instead

• modify settings.tsx to change the texts and Image.
  • image is the main image that is shown. You could change it to your project logo.
  • headerText is the website header. You could change it to your project name.
• Decide if you want to allow multiple mints by a single user at the same time and in your .env file set NEXT_PUBLIC_MULTIMINT accordingly to true or false. By default a maximum of 15 NFTs can be minted at the same time this is because of wallet limitations. If you want to have less change NEXT_PUBLIC_MAXMINTAMOUNT in .env.
• Change Priority fees if you want. By default it is set to the cheapest that is still considered to have priority fees. https://twitter.com/CloakdDev/status/1776661443330339285

Fees

This ui has a buy me a beer feature. Each mint will transfer a very small amount (0.005) of SOL to a tip wallet. If you do not want to support me feel free to change the NEXT_PUBLIC_BUYMARKBEER variable to false. I would appreciate it though if you leave it on. 🍻

To do

• Add NFT Picker of nftBurn and nftPayment guards
