Mint new NFTs into existing collections on Solana. Support both self-minting and minting to specific recipients with custom metadata.

​
Usage

// Mint to your own wallet
const nft = await agent.mintNFT(
  new PublicKey("collection-address"),
  {
    name: "My NFT",
    uri: "https://arweave.net/nft.json"
  }
);

// Mint to a recipient
const nft = await agent.mintNFT(
  new PublicKey("collection-address"),
  {
    name: "Gift NFT",
    uri: "https://arweave.net/gift.json"
  },
  new PublicKey("recipient-address")
);

​
Parameters

ParameterTypeRequiredDescription
collectionMintPublicKeyYesCollection address to mint into
metadata.namestringYesName of the NFT
metadata.uristringYesMetadata URI for the NFT
recipientPublicKeyNoRecipient address (defaults to minter)

LangChain Tool Prompts

// Basic NFT mint to own wallet
{
  "collectionMint": "J1S9H3QjnRtBbbuD4HjPV6RpRhwuk4zKbxsnCHuTgh9w",
  "name": "Awesome Art #1",
  "uri": "https://arweave.net/nft.json"

Example Implementation

import { SolanaAgentKit } from "solana-agent-kit";
import { PublicKey } from "@solana/web3.js";

async function mintCollectionNFTs(agent: SolanaAgentKit) {
  // Collection address
  const collection = new PublicKey("collection-address");
  
  // Mint to own wallet
  const nft1 = await agent.mintNFT(
    collection,
    {
      name: "My NFT #1",
      uri: "https://arweave.net/nft1.json"
    }
  );
  console.log("Minted NFT:", nft1.mint.toString());

  // Mint to recipient
  const recipient = new PublicKey("recipient-address");
  const nft2 = await agent.mintNFT(
    collection,
    {
      name: "Gift NFT #1",
      uri: "https://arweave.net/nft2.json"
    },
    recipient
  );
  console.log("Minted gift NFT:", nft2.mint.toString());
}

​
Metadata Format

Your NFT metadata URI should point to a JSON file with this structure:

{
  "name": "NFT Name",
  "symbol": "SYMBOL",
  "description": "NFT description",
  "image": "https://arweave.net/nft-image.png",
  "attributes": [
    {
      "trait_type": "Background",
      "value": "Blue"
    }
  ],
  "properties": {
    "files": [
      {
        "uri": "https://arweave.net/nft-image.png",
        "type": "image/png"
      }
    ]
  }
}

​
Implementation Details

  • Verifies collection membership
  • Handles metadata on-chain
  • Supports custom recipient addresses
  • Creates associated token accounts
  • Manages NFT minting authority

​
Error Handling

try {
  const nft = await agent.mintNFT(collection, metadata, recipient);
} catch (error) {
  if (error.message.includes("collection not found")) {
    // Handle invalid collection
  } else if (error.message.includes("metadata")) {
    // Handle metadata issues
  }
}

​
Best Practices

  1. Metadata Management

    • Use permanent storage (Arweave)
    • Include high-quality images
    • Validate metadata format
    • Follow collection standards

  2. Collection Verification

    • Verify collection existence
    • Check minting authority
    • Validate collection standards
    • Monitor supply limits

  3. Recipient Management

    • Validate recipient addresses
    • Create token accounts
    • Handle transfer failures
    • Confirm receipt

  4. Technical Considerations

    • Monitor network status
    • Handle rate limits
    • Implement retries
    • Log transactions
