RigoBlock is an open source protocol that lets you create and run a fund on the Ethereum blockchain. The funds operate in an autonomous way, controlled by a private key or by another smart contract. The RigoBlock protocol is built in a modular and abstracted way, so that developers can bring their own "asset management version" to the protocol as long as they follow some basic guidelines. We have created the first two classes of funds: Vault and Drago. A Vault allows for safe Ether hot-storage. A Drago allows for trading on decentralized exchanges. Users can create and run as many funds as they want. RigoBlock is an open and permissonless protocol, with no fees.
