Non-fungible Token (NFT) Example 👋

This repository contains an example implementation of a non-fungible token contract in Rust which uses near-contract-standards and workspaces-rs tests.

Note: If you'd like to learn how to create an NFT contract from scratch that explores every aspect of the NEP-171 standard including an NFT marketplace, check out the NFT Zero to Hero Tutorial.

How to Build Locally?

Install cargo-near and run:

cargo near build

Note: to avoid issues, be sure to update your Rust compiler with rustup update stable

How to Test Locally?

cargo test

How to Deploy?

To deploy manually, install cargo-near and run:

# Create a new account
cargo near create-dev-account

# Deploy the contract on it
cargo near deploy <account-id>

# Initialize the contract
near call <account-id> new_default_meta '{"owner_id": "<account-id>"}' --accountId <account-id>

Basic methods

# View metadata
near view <account-id> nft_metadata

# Mint a NFT
near call <account-id> nft_mint '{"token_id": "0", "token_owner_id": "<account-id>", "token_metadata": { "title": "Olympus Mons", "description": "Tallest mountain in charted solar system", "media": "https://upload.wikimedia.org/wikipedia/commons/thumb/0/00/Olympus_Mons_alt.jpg/1024px-Olympus_Mons_alt.jpg", "copies": 1}}' --accountId <account-id> --deposit 0.1

# View tokens for owner
near view <account-id> nft_tokens_for_owner '{"account_id": "<owner_id>"}'

# Transfer a NFT
near call <account-id> nft_transfer '{"token_id": "0", "receiver_id": "<receiver-id>", "memo": "transfer ownership"}' --accountId <account-id> --depositYocto 1
