Xangle is a public data disclosure service for the global cryptocurrency market. Our goal is to resolve the issue of information asymmetry pervasive in the crypto market today. The Xangle information disclosure platform is based on the framework that currently exists in the traditional financial markets such as DART in S. Korea, EDGAR in the USA, and international credit rating corporations. Xangle provides fundamental and comprehensive information, which includes both on-chain and off-chain data, to enable the valuation of projects. We are actively working with token projects, exchanges, and investors to institutionalize public data disclosure practices.
