XinFin Coin, known by its symbol XDCE, was a digital asset associated with the XinFin network. Initially, XDCE was designed as an Ethereum-based token which aimed to complement the XinFin's native token, XDC, by facilitating easier liquidity on Ethereum-centric exchanges and enabling users to benefit from the Ethereum ecosystem's features. However, it is important to note that the XDCE token was part of an earlier phase in the development of the XinFin network. 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.

XDCE was primarily used to provide interoperability between the XinFin network and Ethereum-based platforms. This was intended to enable users to leverage Ethereum’s extensive decentralized finance (DeFi) ecosystem while still being part of XinFin's own ecosystem. Users could, for instance, swap between XDCE and the native XDC tokens, facilitating easier exchange and liquidity across different blockchain platforms.
