Yellowdex

Remember every crypto address you encounter. Yellowdex automatically detects crypto addresses on any webpage—from Etherscan to Twitter—and lets you label them with custom names and organizations. Build your personal address book as you browse, and instantly recognize wallets you've seen before. Features: - Automatic address detection across all websites, including block explorers like Etherscan - Built-in labels for well-known entities so recognized wallets show up right away - Two-tier labeling: entity names + address labels (e.g., "Uniswap: Hot Wallet") - Entity grouping, tags, and collections for organization - Multi-chain aware—label addresses across different networks - Optional cloud sync to keep your labels backed up and up to date across devices - Shared collections to collaborate and share labeled addresses with others - One-click toggle to show or hide labels on any page - Excluded sites list to turn the extension off on sites you choose - Import/export your data anytime Currently in beta. We recommend periodically exporting your labels as a backup while we refine the experience.
