We recognized significant potential in the ERC404 standard to revolutionize the memecoin space by enabling memecoins to function like NFTs and vice versa. However, the original ERC404 implementation faced practical issues:

• In legacy ERC404, 1 token equaled 1 NFT, resulting in token prices reaching thousands of dollars, unlike typical memecoins which often have many leading zeros (<0.0001). We addressed this by allowing deployers to specify the number of tokens per NFT, such as 10,000 tokens equaling 1 NFT, thereby increasing supply to resemble that of common memecoins.
• In the original ERC404, users could regenerate traits by transferring tokens between wallets, making it easy to farm rare items. We eliminated trait regeneration upon transfer; instead, users must sell their NFT and repurchase it from a DEX.
• Previously, if a user sold and rebought fractional NFTs (e.g., 0.1 NFT), the traits would change, resulting in a completely different NFT. We corrected this by tracking the user's last fractional item, effectively preventing the exploitation of rare traits.
• Miners could influence trait randomization during minting. We introduced verifiable randomness using Chainlink VRF and Automation to solve this issue.
• The dynamic NFT generation and art based on DNA presented a challenge in creating the metadata for them. We decided to set up a dedicated server for this generation, using off-chain data to complement the contract data. We use IPFS to store the off-chain data, saving the hash in the contract, which allows for a unique reference to this information.

We believe our enhancements can provide a foundation for future memecoin and NFT projects, positioning Base as the home of next-gen memecoins that attract a billion users to the blockchain.
