#Quick News# Data scientist Carlos Mercado pointed out that stablecoins, as the most liquid and adopted assets among on-chain real-world assets (RWA), are increasingly becoming the backbone of DeFi. Stablecoins can enable efficient cross-border transactions, reduce dependence on the traditional banking system, and support complex financial products such as decentralized lending platforms, liquidity pools, and liquidity mining protocols. However, many RWAs, such as real estate, have poor liquidity due to pricing difficulties and complex legal systems. Stablecoins can solve these problems. As digital cash, holding it means owning it, achieving globalization and decentralized adoption. Although there are huge benefits to introducing on-chain activities, there are also risks, and the risk of systemic market fluctuations needs to be mitigated by providing stable and liquid assets. At present, stablecoins denominated in US dollars, such as USDC and USDT, have become an indispensable part of DeFi infrastructure.
