### What is NFT20? NFT20 tokens are ERC-20 tokens that are backed 1:1 by ERC-721 or ERC-1155 NFT deposits on the smart contract. NFT20 tokens can be verified directly on-chain. NFT20 tokens make conventional NFTs "fungible" and trader-friendly. With NFT20, you can buy, sell, and trade NFTs in whole or fractions as easily as any other ERC-20 token. ### Why is NFT20 Important? NFT20 offers users the following benefits: * **🧩 Fractionalization:** Traditional NFTs are too pricy? With NFT20 tokens, you can own parts of an otherwise expensive NFT. * **🧭 Decentralized:** Completely trustless! Verify assets on-chain, don’t worry about KYC or regulations. Your keys, your NFTs. * **🔁 Multi-asset Swap:** Trade without restrictions. Exchange your assets for any other coin or NFT20s, the sky's the limit. * **💧 Liquidity Mining:** Become a liquidity provider and add to pools to earn fees (and more).
