Candy machine team group allocation configuration

Question

What is the best way to implement some « team allocation » in Candy Machine v3 (sugar)?

Maybe a « group » with 0 sol mint price? How do I specify allowed addresses in such a group though?

Answer 1

By "Team Allocation" I am assuming you are suggesting some amount of mints are allocated to your the team. To do this, you'd probably want a Guard Group and a combination of multiple Candy Guards:

• Allow List to specify the wallets that can mint
• Mint Limit to specify how many each of those wallets can mint
• Start Date and End Date to determine when those users can mint

You could alternatively do something like Token Burn but this would require distributing WL tokens and could be transferable.

Here's a list of All Guards.

Using JS/Umi--that'd be something like:

import { some, sol, dateTime } from "@metaplex-foundation/umi";
import { getMerkleRoot } from "@metaplex-foundation/mpl-candy-machine";

const allowList = [
  "Ur1CbWSGsXCdedknRbJsEk7urwAvu1uddmQv51nAnXB",
  "GjwcWFQYzemBtpUoN5fMAP2FZviTtMRWCmrppGuTthJS",
  "AT8nPwujHAD14cLojTcB1qdBzA1VXnT6LVGuUd6Y73Cy",
];

const candyGuard = await fetchCandyGuard(umi, candyMachine.mintAuthority);
await updateCandyGuard(umi, {
  candyGuard: candyGuard.publicKey,
  guards: candyGuard.guards,
  groups: [
    {
      label: "early",
      guards: {
        //add other guards here
        mintLimit: some({ id: 1, limit: 5 }),
        allowList: some({ merkleRoot: getMerkleRoot(allowList) }),
        solPayment: some({ lamports: sol(1), destination: treasury }),
        startDate: some({ date: dateTime("2022-10-18T16:00:00Z") }),
        endDate: some({ date: dateTime("2022-10-18T17:00:00Z") }),
      },
    },
    {
      label: "late",
      guards: {
        solPayment: some({ lamports: sol(3), destination: treasury }),
        startDate: some({ date: dateTime("2022-10-18T17:00:00Z") }),
        botTax: some({ lamports: sol(0.001), lastInstruction: true }),
      },
    },
  ],
}).sendAndConfirm(umi);
