According to Bijie.com, stablecoin issuers Circle and Stripe recently launched their own public blockchains, Arc and Tempo, respectively, aiming to build dedicated settlement layers to optimize payment efficiency and cost control. USDT sidechains Stable, Bitcoin sidechains Plasma, and RWA chain Converge have also been launched simultaneously, focusing on cross-border remittances and institutional clearing. Experts believe that while these chains will challenge stablecoin-focused public chains like TRON, Ethereum and Solana remain irreplaceable due to their open ecosystems. Retail investors can look out for testnet airdrops, node staking, and ecosystem incentive opportunities.
