Pre-deployed Contract

Create your first non-fungible token by using a pre-deployed NFT smart contract which works exactly as the one you will build on this tutorial.

---

Prerequisites

To complete this tutorial successfully, you'll need a NEAR Wallet and NEAR CLI

---

Using the NFT contract

Minting an NFT token on NEAR is a simple process that involves calling a smart contract function.

To interact with the contract you will need to first login to your NEAR account through near-cli.

---

Setup

Log in to your newly created account with near-cli by running the following command in your terminal:

near account import-account using-web-wallet network-config testnet

Set an environment variable for your account ID to make it easy to copy and paste commands from this tutorial:

export NEARID=YOUR_ACCOUNT_NAME

---

Minting your NFTs

We have already deployed an NFT contract to nft.examples.testnet which allows users to freely mint tokens. Let's use it to mint our first token.

Run this command in your terminal, remember to replace the token_id with a string of your choice. This string will uniquely identify the token you mint.

Short

near call nft.examples.testnet nft_mint '{"token_id": "TYPE_A_UNIQUE_VALUE_HERE", "receiver_id": "'$NEARID'", "metadata": { "title": "GO TEAM", "description": "The Team Goes", "media": "https://bafybeidl4hjbpdr6u6xvlrizwxbrfcyqurzvcnn5xoilmcqbxfbdwrmp5m.ipfs.dweb.link/", "copies": 1}}' --gas 100000000000000 --deposit 0.1 --accountId $NEARID --networkId testnet

Querying your NFT

To view tokens owned by an account you can call the NFT contract with the following near-cli command:

Short

near view nft.examples.testnet nft_tokens_for_owner '{"account_id": "'$NEARID'"}' --networkId testnet

Full

near contract call-function as-read-only nft.examples.testnet nft_tokens_for_owner json-args '{"account_id": "'$NEARID'"}' network-config testnet now

Example response:

[
  {
    "token_id": "Goi0CZ",
    "owner_id": "bob.testnet",
    "metadata": {
      "title": "GO TEAM",
      "description": "The Team Goes",
      "media": "https://bafybeidl4hjbpdr6u6xvlrizwxbrfcyqurzvcnn5xoilmcqbxfbdwrmp5m.ipfs.dweb.link/",
      "media_hash": null,
      "copies": 1,
      "issued_at": null,
      "expires_at": null,
      "starts_at": null,
      "updated_at": null,
      "extra": null,
      "reference": null,
      "reference_hash": null
    },
    "approved_account_ids": {}
  }
]

Congratulations! You just minted your first NFT token on the NEAR blockchain! 🎉

Now try going to your NEAR Wallet and view your NFT in the "Collectibles" tab.

Final remarks

This basic example illustrates all the required steps to call an NFT smart contract on NEAR and start minting your own non-fungible tokens.

Now that you're familiar with the process, you can jump to Contract Architecture and learn more about the smart contract structure and how you can build your own NFT contract from the ground up.

Happy minting! 🪙
