A library in Elixir for handling compressed NFTs (cNFTs) on Solana. Published here https://hex.pm/packages/mpl_bubblegum_nifs

Installation

Add mpl_bubblegum_nifs to your list of dependencies in mix.exs:

Usage

1. Initialize Connection

Before using the library, establish a connection to Solana RPC. Use a Helius RPC URL, as native Solana RPC does not support DAS API.

MplBubblegum.Connection.create_connection(secret_key, rpc_url)

---

2. Create a Merkle Tree

This function initializes a new Merkle tree, which is required for minting compressed NFTs.

merkle_tree = MplBubblegum.create_tree_config()
IO.puts("Tree created at: #{merkle_tree}")

---

3. Mint a Compressed NFT

To mint a cNFT, provide the Merkle tree address and metadata details.

tx = MplBubblegum.mint_v1(
  "9ppyWc9LjccAJPchEoPYatZQgk5PwJgUhZi3rTd8skcE", # Merkle tree address
  "Solana Warrior",    # NFT Name
  "SW",               # Symbol
  "https://bafybeih7oz5pds33io34ud5ut4fd5a2jj74zoduiec2fw4oz24yqfo4aey.ipfs.w3s.link/1034.json", # Metadata URI
  250,               # Seller Fee Basis Points
  100                # Creator Share
)

IO.puts("Minted cNFT, tx: #{tx}")

---

4. Transfer a cNFT

To transfer ownership of a compressed NFT, provide the asset ID and recipient's address.

tx = MplBubblegum.transfer(
  "6pfiemDtGpzFTWmT2rfNmvMAdPzvYcdzXJXquwjbB97q", # Asset ID
  "6hxBtjckJxUf9FM8V9dDq1Wux5azG2a64osiNwP1KwDN" # Recipient Address
)

IO.puts("Transferred cNFT, tx: #{tx}")
