Solana Fellowship Program 2024 - Module 8 - Compressed NFTs

Create a cNFT collection of your own profile picture and social links as metadata and airdrop it to other fellows.

This is typically accomplished in a few steps:

Setting up the Merkle tree.
Setting up the collection.
Minting the compressed NFTs.
Transferring to another wallet.

Setting up the project `.env`

Generate wallets

solana-keygen grind --starts-with F:3

Result:

Searching with 10 threads for:
	3 pubkeys that start with 'F' and end with ''

Step 0 - Install dependencies

npm install

Step 1 - Create Merkle

Noted: Faucet to account KEYPAIR_SRC -> This accout is signer transaction

npm run merkle

Result tx signature:

Signature: nX4fXjqKR6GXHVpxihXXn96iHTGMrjHtZZvFyUuxhMT2dr2PfJZsr3R2Hjsd7yuuHdzaKGYQ9bmosuCWEYYRUsP

Step 2 - Create Collection

Change name and symbol in src/collection.ts

For example

      createMetadataAccountArgsV3: {
        data: {
          name: "Dustin cNFTs",
          symbol: "DUSTIN",
          uri: env.COLLECTION_METADATA,
          sellerFeeBasisPoints: 0,
          creators: [
            { address: keypair.publicKey, verified: true, share: 100 },
          ],
          collection: null,
          uses: null,
        },
        isMutable: true,
        collectionDetails: null,
      },

Result:

Successfull created NFT collection with collection address: FYMJxSUDJoyYAwY6zyb2oWWJaJ9UyfPtTECgD1E8Q1zh

Step 3 - Mint NFTs

Change name and symbol in src/mint.ts

      metadataArgs: {
        collection: { key: collectionMint, verified: false },
        creators: [{ address: keypair.publicKey, verified: true, share: 100 }],
        isMutable: true,
        name: "Dustin cNFTs",
        primarySaleHappened: true,
        sellerFeeBasisPoints: 0,
        symbol: "DUSTIN",
        uri: env.NFT_METADATA,
        uses: null,
        editionNonce: null,
        tokenStandard: null,
        tokenProgramVersion: TokenProgramVersion.Original,
      },

Step 4 - Transfer NFTs

Noted: Replace your destination address in src/transfer.ts

      newLeafOwner: new PublicKey(
        "MiCQoU7dk3ddXTNPjFfFwC3YuXNDfZuuqDwd19Cmgpg"
      ),

npm run transfer
