About link

EdenChain describes itself as a blockchain platform for enterprises that aims to replace existing assets with blockchain-based tokens through smart contracts. The platform provides users with technological support to disintermediate and tokenize their assets while protecting private data. These tokenizable assets include both tangible and intangible ones. As these tokens are now tradeable, token owners will have a new means of extracting value from their assets. EdenChain aims to build a blockchain ecosystem that offers users a complete and seamless blockchain experience. In addition to EdenChain (platform service), the team also offers users Dorothy (dApp depository store), MoA (tokenization and asset management tools), and Pegasus (multicurrency payment solution).
