Matchbook is a peer-to-peer betting exchange that allows users to set their own odds and bet against one another, rather than against a traditional bookmaker. Launched in 2014, it offers a unique platform for sports enthusiasts to engage in betting on various events, including sports, politics, and entertainment. Users can both back and lay bets, providing greater flexibility and potential for better odds. With a user-friendly interface and a focus on community-driven betting, Matchbook aims to enhance the overall betting experience while promoting transparency and fairness in the wagering process.
