Ethereum Address Book

Label known wallet addresses and tag transactions as you browse Etherscan.

Browsing Etherscan is hard; Make it easier. The language of the blockchain is notoriously impossible for humans to easily understand. Replace the seemingly random characters with tags we biologicals can understand. - Wallet & Transaction Labels: Save a label for any Ethereum address or transaction hash. Wherever that address appears on Etherscan, your label shows up as a tag right next to it. Name your own wallets, mark known exchanges, flag validators, or call out scammers. For transactions, replace an unreadable 66-character hash with something meaningful like "Paid rent June" or "Validator withdrawal." - Address Poisoning Protection: Scammers send tiny transactions from addresses that look like yours when truncated. Ethereum Address Book only tags addresses or transactions that contain the complete data set in the HTML data of the page; Therefore, if a scammer interacts with your wallet using one that looks identical when truncated, it will not be tagged as yours. - Privacy First: Everything is stored locally in your browser using Chrome's sync storage. Nothing is ever sent to a server. No account, no tracking. - Other Features: Back up and transfer your data via CSV, compatible with Excel and Google Sheets. Customize tag colors for quick visual recognition.
