ICRC7/ICRC37 Implementation for Internet Computer

This repository contains the first complete and production-ready implementation of the ICRC7/ICRC37 NFT standard for the Internet Computer. This implementation is currently under review by the DFINITY Foundation for community validation.

Overview

This project provides a complete solution for NFT management on the Internet Computer, consisting of three main components:

Core NFT Canister: A full implementation of the ICRC7/ICRC37 standard for NFT management Integration Tests: Comprehensive test suite ensuring reliability and correctness

Key Features

• Full ICRC7/ICRC37 standard compliance
• Production-ready implementation
• Complete integration test coverage
• High-performance storage solution
• Transaction history using ICRC3 standard
• Certified HTTP asset serving
• Stable memory storage with heap caching
• Fine-grained access control for assets

Components

Core NFT Canister (src/core_nft)

The main NFT ledger implementation that handles all NFT operations according to the ICRC7/ICRC37 standard. It uses the ICRC3 standard for transaction history and can work with any storage solution.
