ERC404 Overview

The Advent of ERC404

In the evolving landscape of digital assets, ERC404 emerges as a novel token standard, introduced in early February 2024. This standard heralds a new era by merging the fungibility of ERC20 tokens with the distinctiveness of ERC721 Non-Fungible Tokens (NFTs). Designed to serve a dual purpose, ERC404 tokens function both as fungible tokens for applications like trading and staking and as unique NFTs signifying exclusive ownership rights. This hybrid nature paves the way for innovative digital asset utilization, encapsulating the advantages of both token types in one cohesive framework.

How Does It Work?

ERC404 tokens are implemented through a set of standards on the Ethereum blockchain, adeptly blending the functionalities of fungible (ERC20) and non-fungible (ERC721) tokens. An ERC404 contract is adept at producing both an NFT and its fungible token counterpart at a predetermined ratio, bridging the gap between fungible and non-fungible assets. For example, a project like XYZ could release 10,000 NFTs paired with 10,000 XYZ tokens, establishing a tangible connection between the two asset types.

This integration facilitates liquidity pools for ERC404 tokens, addressing the liquidity challenges often encountered in NFT trading. By introducing fungible tokens into the mix, ERC404 innovatively enhances liquidity and project viability, offering a fresh perspective on digital asset trading.

Hybrid Nature

The ERC404 standard exemplifies a hybrid model, assimilating the traits of ERC20 and ERC721 tokens. This dual functionality spawns assets that are simultaneously interchangeable and unique, supporting a broad spectrum of applications through a singular smart contract framework.


A prime application of ERC404 tokens unfolds in event ticketing and fan engagement scenarios. Picture an ERC404 token that affords you access to a concert's front-row seats and exclusive perks like a VIP meet-and-greet session. By combining the liquidity benefits of ERC20 tokens with the unique experiences provided by ERC721 NFTs, ERC404 tokens redefine our approach to ticketing and engagement within the entertainment sector.

Native Fractionalization of NFTs

A hallmark of ERC404 is its inherent support for the fractional ownership of NFTs. Contrary to traditional ERC-721 tokens, which symbolize a single, indivisible asset, ERC404 enables the division of NFT ownership into smaller, tradable shares. This feature significantly boosts the liquidity and approachability of high-value assets, facilitating broader participation and investment opportunities.

Enhanced Liquidity

ERC404's support for fractional ownership directly tackles the liquidity shortfall of conventional NFTs, democratizing access to premium assets. This innovation simplifies the exchange process on trading platforms, making high-value assets attainable to a more extensive audience.


ERC404 signals a transformative phase for digital assets, delivering unparalleled adaptability, liquidity, and opportunities for creators and investors alike. Its inventive strategy of amalgamating fungible and non-fungible elements under a unified standard promises to revolutionize various industries, spanning entertainment, investment, and more, setting a new benchmark for digital asset innovation.
