Nick Name Service

The NickNameService contract allows users to mint tags as soulbound NFTs for any address. Unlike Etherscan's tags, these tags are on-chain, immutable, and beautifully visualized as NFTs with SVG metadata.

Key Features

• Soulbound NFTs: Non-transferable tokens that remain attached to the recipient address
• Beautiful SVG Metadata: Dynamic color gradients and animated scrolling text
• Character Validation: Only allows 7-bit ASCII characters (0-9, a-z & -)
• Length Limits: Tags must be between 3 and 32 characters
• On-chain Storage: All nicknames and metadata are stored fully on-chain

Use Cases

• Tag addresses as good: nns.mint(friendAddress, "good-guy");
• Identify scammers: nns.mint(scammerAddress, "scammer");
• Create a personal address book: Tag addresses with memorable names
• Add reputation: Build on-chain reputation for addresses

Technical Details

• ERC721 Implementation: Standard NFT interface with soulbound properties
• SVG Generation: Creates SVG images dynamically for each nickname
• JSON Metadata: Includes name, description, SVG image, and attributes
• Base Chain Deployment: Running on Base for lower gas costs
