Stablecoins are cryptoassets engineered to hold a predictable value, often referencing fiat currencies like the US dollar. Issued in forms ranging from fully collateralised custodial models to decentralised, crypto-backed designs, they provide fast, borderless settlement rails for trading, DeFi, remittances and on-chain savings without typical crypto price swings.

Now central to on-chain liquidity and tokenised finance, stablecoins act as the connective tissue between traditional money and Web3: instantly transferable, transparent on public ledgers and integrated across exchanges, lending markets and payment flows, with live metrics tracked by dashboards such as DefiLlama’s global stablecoin overview.
