What Is ERC-404? Everything You Need To Know

The world of cryptocurrencies is constantly growing, and new innovations emerge regularly. One of the latest buzzwords is ERC-404, a novel token standard for digital assets on the Ethereum blockchain.

What is ERC-404?

Think of token standards as sets of rules governing how tokens on a blockchain like Ethereum behave. ERC-404, developed by “ctrl” and “Acme,” blends features of existing standards ERC-20 (fungible tokens) and ERC-721 (non-fungible tokens) to create “semi-fungible” tokens. These tokens offer a unique approach for various use cases.

What Makes it Special?

  • Hybrid Functionality: ERC-404 tokens combine fungible and non-fungible traits, meaning they can be divided into smaller parts while retaining unique aspects. Imagine owning a fraction of a rare digital artwork!
  • Native Liquidity: Unlike traditional NFTs, ERC-404 tokens have built-in mechanisms for easier trading and fractional ownership. No need to rely solely on marketplaces; you can trade fractions as desired.
  • Programmable Scarcity: The token supply can dynamically adjust through code, opening doors for innovative tokenomics models and controlling scarcity.

How Does it Work?

One intriguing feature is the linking of NFT rewards to ownership. Owning a complete ERC-404 token might grant you an NFT from the underlying project. When you sell the token, the NFT gets “burned,” ensuring both tokens trade independently.

Safety Considerations:

While ERC-404 is still experimental and lacks formal approval, rigorous testing has been conducted. Use caution, as it’s still early days.

Impact on Ethereum Price?

While innovative, ERC-404 projects likely won’t significantly impact Ethereum’s price just yet.

What are Some ERC-404 Projects?

  • Pandora: The Pandora project showcases the standard’s potential, with its token price skyrocketing from $212 to $32,840!
  • DeFrogs: A collection of Pepe the Frog-themed NFTs using a variant of the standard, offering a unique spin on digital collectibles.
  • Monarch: Monarch Introduces a gamified approach, allowing NFT evolution through on-chain competitions, shifting value perception from rarity to activity.

The Future of ERC-404:

Efforts are underway to gain official recognition through an Ethereum Improvement Proposal (EIP). If successful, ERC-404 could become a standard framework for developing innovative applications on the Ethereum blockchain.


This is a new and evolving technology. Do your own research before investing in any ERC-404 projects.


What is ERC-404?

ERC-404 is a new token standard on the Ethereum blockchain that allows for the creation of “semi-fungible” tokens, combining features of both fungible (like ERC-20) and non-fungible (like ERC-721) tokens. This enables unique use cases like fractionalized NFTs and dynamic token supply.

Is ERC-404 safe?

While undergoing rigorous testing, ERC-404 remains experimental and lacks formal approval. Proceed with caution as it’s a relatively new technology.

What’s its impact of ERC-404 on Ethereum price?

While innovative, ERC-404 projects are unlikely to significantly impact Ethereum’s price in the short term.

Will ERC-404 become an official standard?

Efforts are underway to gain official recognition through an Ethereum Improvement Proposal (EIP). If successful, it could become a widely adopted standard for innovative applications.

Should I invest in ERC-404 projects?

Thorough research is crucial before investing in any project, regardless of the token standard used. Remember, cryptocurrencies are inherently volatile and carry inherent risks.
