XinFin Coin (XDCE) was an Ethereum-based token associated with the XinFin network, intended to bridge liquidity between Ethereum and XinFin ecosystems. However, after the full launch of XinFin's mainnet in 2019, the XDCE contract was terminated, marking the shift towards exclusively using the native XDC token. The creation and initial utility of XDCE were geared towards enhancing interoperability and providing users with access to broader DeFi ecosystems.
