The biggest player in stablecoins is back Meta, the parent company of Facebook, with a market value of $1.6 trillion, plans to re-enter the stablecoin market in the second half of 2026. This is not its first attempt. As early as 2019, Meta (then known as Facebook) led the launch of the stablecoin Libra, which aimed to establish a cross-border payment network. The project was later renamed Diem, but was ultimately halted under pressure from U.S. regulators. The core technical team behind Libra and Diem has not disappeared. Avery Ching, the former head of blockchain technology for Libra, founded Aptos $APT. Another core member, Evan Cheng, founded Sui $SUI. Both of these public chains are based on the Move language, which was the core smart contract language developed for Libra.
