Mastercoin, launched in 2013 via the Bitcoin forum, was the world’s first ICO (Initial Coin Offering) token. It successfully raised 4,740 BTC during its crowdfunding campaign. As the second cryptocurrency created after Bitcoin, Mastercoin also holds the distinction of being the world’s first protocol coin. This pioneering token preceded the launch of Ethereum, setting the foundation for decentralized platforms that would follow.
