Source: Stacy MuurSince the start of February, a new experimental Ethereum token standard has taken web3 by storm.ERC-404, the novel token standard has given rise to a subclass of crypto assets that have garnered a market cap of over $300m.ERC-404 tokens such as DeFrogs have changed the NFTs narrative forever with a new and innovative hybrid approach.The interest generated by these new tokens can be reflected in their price action, for instance, DeFrogs went from a few dollars to its all-time-high of $ 3,987.97within 3 days.Source: BinanceWhat is ERC-404?First, a token standard is a set of rules determining how a cryptocurrency or token is created, functions, behaves and interacts within a particular blockchain network.On the Ethereum blockchain, there are two prominent token standards, ERC-20 which is the standard for fungible tokens and ERC-721, the standard for non-fungible tokens (NFTs). ERC-404 combines both of these standards into one and the result is a semi-fungible token that can be an NFT or a typical token. This means that ERC-404 tokens can be traded on NFT marketplaces as well as on exchanges. ERC-404 is therefore an experomental token standard for digital assets on the Ethereum blockchain that has the properties of both an NFT and a token. It was developed by two pseudonymous creators “Ctrl” and “Acme”. The token standard was named after the “404 not found” error message that is displayed when we try to access web pages that are no longer available. Understanding ERC-404To understand ERC-404 we first need to understand the meaning of “fungible”. Fungible refers to when an item is replaceable or interchangeable with another identical item of the same type and still performs the same function whilst retaining the same value. A $100 bill can be replaced with any other $100 bill and still retain the same value and perform the same function.ERC-20 tokens are fungible and can be fractionalized i.e. they can be broken down into small fractions. This is why they are the token standards for coins on the Ethereum blockchain. Meanwhile, ERC-721 is the standard for non-fungible tokens (NFTs), these types of tokens can not be fractionalized i.e. you can not own 0.2 or 0.45 of an NFT. It's either you have a whole or nothing. ERC-404 tokens merge these two properties and features. You can either own an entire NFT or own fractions of it, consequently, you can trade these fractions on exchanges or trade the entire NFT on an NFT marketplace. But how? Mint and Burn  ERC-404 tokens can pull this off through a mechanism known as “mint and burn”. When ERC-404 tokens are issued each NFT is bonded with an ERC-20 token.  If the NFT is broken down into fractions the NFT is burnt and the tokens can be traded. If anyone accumulates enough tokens to form a whole an NFT is automatically minted to their wallet.That is, ERC-721 tokens are tied to ERC-20 tokens, where an ERC-20 token only represents an NFT when it is a whole token, not a fraction.Once a whole (1,2,3…N even numbers) is broken down into fractions for trading as an ERC-20 token, the NFT is burnt. When enough tokens to form a whole are accumulated, for instance, two complementary fractions (e.g. 0.4 and 0.6) this will form a full token and a new NFT is minted to the wallet of the owner.  This new innovative token standard ensures fractionalization of NFTs making them more liquid, instead of waiting for a buyer on an NFT marketplace you can easily sell it on an exchange that it is also listed on. Let's highlight some notable ERC-404 projects.DeFrogs One of the pioneering ERC-404 projects, DeFrogs is both the first PFP ERC-404 project as well as the first ERC-404 meme coin. The hybrid(ERC-721 + ERC-20), semi-fungible project created by the pseudonymous creator "Dalt Wisney" is a 10,000 collection of cartoon Pepe-and-DeGods-inspired PFPs. DeFrogs’ combination of meme culture with the ERC-404 narrative has been able to garner a buzzing and growing community. (Tg: @DeFrogs)DeFrogs launched via a fair launch (coingecko.com/learn/what-is-a-fair-launch-in-crypto) on Uniswap, with 80% of the supply added to the liquidity pool while just 1% of DeFrogs supply is currently listed on Opensea.DeFrogs is tradable on supported exchanges and NFT marketplaces, Defrog is listed on exchanges such as MEXC, CoinW, BingX and AscendEX(BitMax). At the time of writing the market cap of DeFrogs is $11.9m and is currently trading at $1,050. DeFrogs have established themselves as not just one of the key ERC-404 projects but one of the major projects of 2024 so far.With more than enough room for growth and its ever-growing community, DeFrogs is poised to attain blue-chip status. Other ERC-404 Projects Apart from DeFrogs, there have been other ERC-404 projects pushing the narrative forward. One such project is Pandora: A collection of 10,000 ERC-404 tokens created by the pseudonymous “Ctrl” and “Acme” the creators of the experimental token standard. Pandora is the very first ERC-404 token making it the first semi-fungible ERC-404 token to be listed and traded on a centralized exchange. With a positive reception, Pandora has seen its market cap climb over $200m since its launch via Uniswap. The Future of ERC-404The ERC-404 is still “experimental” This means it is an unofficial token standard because it has not undergone an EIP review, the Ethereum Improvement Proposal (EIP) is the process of introducing a new feature or functionality to Ethereum. Despite this, the innovative nature of this standard has made its reception more positive and there are indeed plans to submit an official Ethereum Improvement Proposal for the new token standard. What DeFrogs and other ERC-404 tokens have done is nothing short of revolutionary the idea of owning an NFT and a fungible token combined in a single token is very attractive to crypto enthusiasts this accounts for the positive price action that followed ERC-404 projects at launch. The future of the ERC-404 token standard is worth looking forward to.Tap to try 👉binance.com/web3wallet#ERC-404 #TrendingTopic

In the ever-evolving landscape of Web3 and decentralized technologies, non-fungible tokens ( #nfts ) have captured the imagination of creators, collectors, and investors alike. These unique digital assets, often associated with art, music, and virtual real estate, have become a significant force in the crypto space. However, they also come with their share of challenges, including security risks and phishing attacks.
Enter #ERC-404 , an experimental and unofficial Ethereum token standard that aims to address some of these issues. Let’s dive into what ERC-404 is, how it works, and its potential impact on the NFT ecosystem.
What Is ERC-404?
ERC-404 is not your typical NFT standard. It combines elements from two existing standards: #ERC-20 (used for fungible tokens) and #ERC-721 (used for non-fungible tokens). The result is a hybrid token that offers unique features and possibilities.
Shared Ownership and Reduced Phishing Risk
The standout feature of ERC-404 is shared ownership. Unlike traditional NFTs, which are usually associated with a single wallet address, ERC-404 tokens can be owned by multiple wallets simultaneously. Here’s how it works:
Multiple Owners: An ERC-404 token can have several owners, each holding a fraction of the token. This shared ownership model distributes control and reduces the risk of a single point of failure. Even if one wallet is compromised, the NFT remains secure as long as other owners maintain control.Phishing Mitigation: Phishing attacks targeting individual wallets have plagued the NFT space. By allowing multiple wallets to collectively own an NFT, ERC-404 makes it harder for malicious actors to exploit unsuspecting users. Even if one owner falls victim to phishing, the NFT’s integrity remains intact.
Tokenization of Exposure
Another intriguing aspect of ERC-404 is the concept of tokenizing exposure. Imagine you own a fraction of a valuable digital artwork—an NFT representing a famous painting, for instance. With ERC-404, you can tokenize your partial ownership. Here’s how it benefits you:
Liquidity and Trading: Fractional ownership tokens can be traded on decentralized exchanges (DEXs) or specialized platforms. Investors can buy and sell these tokens without needing to acquire the entire NFT. This liquidity unlocks new possibilities for NFT markets.Staking and Collateral: Tokenized exposure allows you to stake your holdings or use them as collateral in DeFi protocols. You retain ownership while leveraging the value of the NFT for other financial activities.
Challenges and Considerations
While ERC-404 introduces exciting possibilities, it’s essential to approach it with caution:
Smart Contract Risks: As an experimental standard, ERC-404 may have undiscovered vulnerabilities. Users should thoroughly review smart contracts and exercise due diligence.Regulatory Uncertainties: The legal and regulatory landscape for NFTs and tokenized assets is still evolving. ERC-404’s novel features may attract scrutiny or require legal clarity.Adoption and Interoperability: Widespread adoption of ERC-404 depends on wallet providers, exchanges, and developers embracing the standard. Interoperability with existing NFT platforms is crucial.
Conclusion
ERC-404 represents a bold step toward reimagining NFT ownership and security. While it’s not a direct antidote to NFT #phishing , its shared ownership model and tokenization features offer intriguing possibilities. As the Web3 ecosystem continues to evolve, keep an eye on ERC-404 and its impact on the future of digital ownership. 🌐🔒

Just 8 days ago a new token was born that aims to revolutionize how NFTs work. He literally wants to change this technology. And yes, I'm talking about $Pandora First of all, I present to you Pandora The project that has generated this new technology, and as you can see, it seems that they are not doing badly at all with a capitalization of almost 170 million, it seems that this new token is here to stay. But wait, $Pandora is a token? Or is it an NFT? Before explaining, let's give a little context. In the crypto ecosystem we mainly have 3 actors: • Crypto: These assets are NATIVE to each blockchain. They are the ones you use to pay gas/commissions $ETH , $BNB, $ADA, $DOT, $BTC. • ERC-20: These are the tokens ($USDT, $WETH, $UNI.) Actually, they are smart contracts deployed on the blockchain and to be considered ERC-20 tokens, they must follow a series of rules. That is, being strict If the token does not have specific functions, it could not be called a token. Finally, we have the… • ERC-721: The traditional NFTs We must differentiate each one very well, each one is different from the previous one and must be interpreted one way or another. However, this does not happen with ERC-721, NFTs since within each collection, ALL its units are identified. Additionally, by its very nature an NFT, you generally CANNOT split it. That is, you cannot send 0.5 BAYC (Bored Ape) Either you send 1 entire NFT or you do not send anything, this does NOT happen with ERC-20 tokens since you can send 0.001 $USDT (for example) What does this mean for the NFTs? In short, it becomes a less liquid, less tradeable market. Can we solve this problem? Bingo!! I have them for you! Pandora's box And this is when it's time to talk about the new standard that some developers have come up with. Well, not only have they created a new type of smart contract but they have created it, along with their project, $PANDORA A new type of token, which they have named ERC-404, They are literally something like the photo that I will post down here. They have mixed ERC-20 tokens with ERC-721 NFTs, it is a mix of both worlds that tries to improve the liquidity of NFTs. The easiest way to explain how it works is to directly explain the $Pandora project. They are the creators of this new standard for a reason: $Pandora is a collection of 10,000 NFTs. They are boxes like the ones you can see here: But they are somewhat peculiar , if you have 1 $Pandora NFT you will also have 1 $Pandora Token. That is, you have both an nft (ERC-721) and a token (ERC-20), you can sell the NFT in a normal marketplace (like blurr). And you can sell the token on a normal decentralized exchange (Like Uniswap). The beauty of having both is that if you send the NFT to another wallet, the token is also transferred and the same if you do the other way around. If you send the token, you lose the NFT too, it's as if the token and the NFT are tied to each other. They cannot be separated, BUT here comes the curious thing. Do you remember that above I mentioned the problem of NFTs? That is, you cannot send half of the $Pandora NFT, because with the ERC-404, you can send 0.5 $Pandora TOKENS, this means that you can sell half $Pandora. BUT if you do this, now in your wallet, you will have only 0.5 $Pandora or in other words you have half a pandora token. And what about the NFT? The moment you STOP having 1 whole $Pandora token, the NFT that is tied to the token is BURNED, destroyed BUT if you have 1 whole token again, the NFT will magically be created again in your wallet. That is to say, even though there are 10,000 $Pandora tokens, there are NOT 10,000 NFTs since for the tokens to exist they must be COMPLETE. For example, if I split 1 pandora token into 10 wallets (each will have 0.1 Pandora) no one will have 1 Pandora NFT. However, if one of the 10 wallets that have 0.1 buy or receive 0.9 tokens like now will magically have 1 whole token, they will receive a Pandora NFT. In other words, ERC-404 are an NFT and a token at the same time by having 1 token, you also have an NFT, but no one prevents you from having 0.1 tokens, so you can buy or sell a small part of the NFT And the moment you have 1 whole token, you will receive 1 NFT. The problem with ERC-404 is that they are not audited, nor have they passed community review. Actually, it is not a new token standard. Furthermore, it has certain inefficiencies that make that consume much more gas than normal NFTs, that is, they are more expensive to transact. Thank you very much for reading until the end.#TrendingTopic #ERC-404 #NFT $ETH
