Non-fungible Token (NFT) based on Contract Tools 🖼️

This repository contains an example implementation of a non-fungible token contract in Rust which uses near-sdk-contract-tools.

• non-fungible token: https://nomicon.io/Standards/NonFungibleToken/README.html
• near-sdk-contract-tools: https://github.com/near/near-sdk-contract-tools
• near-contract-standards: https://github.com/near/near-sdk-rs/tree/master/near-contract-standards
• near-workspaces-rs: https://github.com/near/near-workspaces-rs

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:

# Deploy the contract and initialize it
cargo near deploy build-non-reproducible-wasm <account-id> with-init-call new json-args '{"owner_id":"<account-id>", "metadata": {"name": "GO TEAM", "symbol": "GOAT", "icon": "https://bafybeidl4hjbpdr6u6xvlrizwxbrfcyqurzvcnn5xoilmcqbxfbdwrmp5m.ipfs.dweb.link/", "spec": "nft-1.0.0"}}' prepaid-gas '100.0 Tgas' attached-deposit '0 NEAR' network-config testnet sign-with-keychain send

Basic methods

# View metadata
near view <account-id> nft_metadata

# Mint a NFT
near call <account-id> nft_mint '{"token_id": "0", "owner_id": "<account-id>", "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
