Can stablecoins enable seamless global fiat exchange through liquidity pools? Stablecoins, pegged to assets like USD or EUR, offer price stability, making them ideal for cross-border transactions. Liquidity pools, powered by decentralized exchanges (DEXs), allow users to swap stablecoins instantly without intermediaries, reducing costs and delays. By pooling assets like USDC, Tether, or DAI, these platforms ensure deep liquidity for fiat-backed stablecoin pairs. Automated market makers (AMMs) maintain fair pricing, while blockchain transparency ensures trust. However, challenges like regulatory hurdles, slippage, and impermanent loss persist. With advancements in cross-chain interoperability and layer-2 scaling, stablecoin liquidity pools could revolutionize global fiat exchange, offering a decentralized, efficient alternative to traditional systems, accessible to anyone with an internet connection.
