Basic Attention

Basic Attention Token (BAT) is a utility token built on Ethereum that serves as the currency inside the Brave browser's digital advertising ecosystem. It aims to address what its creators describe as a broken, fraudulent, and opaque online advertising industry by creating a more transparent relationship between advertisers, website publishers, and the users whose attention is being sought. Advertisers pay BAT to publishers in exchange for user attention, while users are rewarded for engaging with ads rather than having their data harvested by third parties.

BAT is an ERC-20 token that lives on the Ethereum blockchain and is integrated into multiple other ecosystems including Polygon, Avalanche, Solana, and others as reflected in its category listings. Inside the Brave browser, ad targeting is performed entirely on the user's device using locally stored data, meaning no personal information is sent to external servers. When a user opts into seeing ads, BAT flows from advertisers through the system to publishers and participating users according to measured attention signals.

The data provided does not include a protocol fee stream, so fee-based measures such as fee yield or revenue ratios are not available for this asset on this site. The economic activity in the system is driven by advertiser spending in BAT, which is distributed to publishers and users rather than retained by a central protocol treasury. Circulating supply stands at approximately 1,495,724,657 BAT against a maximum supply of 1,500,000,000, meaning 99.71% of all tokens that will ever exist are already in circulation, leaving a dilution overhang of just 0.29% of max supply. The fully diluted valuation is 1.003 times the current market capitalization, reflecting how little remaining issuance there is.
