Basic Attention Token (BAT) is a utility token used by the Brave web browser to reward users for their attention to advertisements and to pay content creators. In this way, BAT enables Brave developers to create an online advertising ecosystem that respects privacy, a system where users choose to view ads in exchange for BAT, or where creators can generate more quality content, allowing them to earn rewards from the traffic they attract.

Firstly, with Basic Attention Token (BAT), users can purchase premium content, donate to content creators, or exchange it for other cryptocurrencies on trading platforms. It can also be used to access services within the Brave ecosystem. Beyond the Brave ecosystem, BAT can be used as a token on decentralised trading platforms or liquidity pools.

Basic Attention Token (BAT) was co-founded by Brendan Eich, who is known for being the co-founder of Mozilla and the creator of JavaScript. Eich has been a key figure in the creation of the Brave browser and in the development of the BAT ecosystem, focusing on improving digital advertising and user privacy.
