A library for building decentralized applications in Typescript and Javascript, currently focused on the Tezos platform.

ConseilJS connects to Tezos nodes for live chain data and operations and to Conseil servers for high-performance analytics on blockchain data. Internally, Cryptonomic uses Nautilus for infrastructure deployments of these services. This is the library at the core of our products, Arronax, Mininax and certainly Galleon. There are now ReasonML bindings as well.

Cryptonomic offers an infrastructure service - Nautilus Cloud which enables quick access to the Tezos platform along with products that make it easier build on it.
