The Macalinao brothers built their reputation in the Solana blockchain community. In early 2021 they created a decentralized exchange for swapping stablecoins called Saber that at its zenith purported to represent $4.15 billion (nearly half) of the crypto value locked up on Solana. Part of the allure of Saber was the interlocking DeFi lego bricks that surrounded it: projects like Sunny, Quarry, Cashio, Goki, and Tribeca.
