$ADA The core stablecoin Djed in the Cardano ecosystem adopts ADA as collateral, achieving price stability through an over-collateralization mechanism. Users mint Djed using ADA, while introducing Shen as a reserve currency to absorb market fluctuations. This not only enhances the practical application value of ADA but also provides a stable value anchor for DeFi, payments, and on-chain governance within the Cardano ecosystem. The development of stablecoins is driving ADA's transition from an investment asset to a utility asset.
