Woofun AI reports that Brave published BAT Roadmap 4.0 on July 9, targeting challenges from AI and cashless economies. The plan integrates BAT, Brave Rewards, and Brave Creators into a transactional attention economy. Key features include a unified Brave Wallet combining traditional payments with self-custodied crypto, and BravePay, a stablecoin-based privacy payment protocol supporting autonomous agent features like x402 and Machine Payment Protocol. Additional initiatives involve virtual and physical payment cards for daily use, a creator contribution protocol for AI micro-royalties, and BAT buybacks funded by revenue. Traditional ad notifications will be phased out by end-2026, shifting rewards to personalized offer walls and loyalty programs.
