## What it is
A reference implementation of the ERC-1808 token standard, an Ethereum proposal for NFTs with nested asset support, originating from the Cocos-BCX blockchain gaming ecosystem. It provides smart contract interfaces for minting, transferring, and authorizing NFTs with cross-chain and multi-level asset capabilities.

## Use cases
- implement ERC-1808 compliant NFT contracts on Ethereum
- create nested NFT assets for blockchain games
- transfer NFTs with attached extension data
- manage multi-chain NFT asset systems
- build game item ownership systems on Ethereum

## When to choose
- building blockchain games that need nested or composable NFT assets
- implementing the ERC-1808 standard specifically
- working within the Cocos-BCX ecosystem

## When to avoid
- you need standard ERC-721 or ERC-1155 tokens with broad tooling support
- you want an actively maintained library
- your project has nothing to do with NFTs or blockchain gaming

## Facets
- artifact type: library
