Designed to index any Cosmos chain

Constellations is a Cosmos chain indexer built in Rust, it is currently the fastest indexer (see performances).

How is it built?

Constellations is built by @fabienpenso entirely in Rust with tendermint-rs, backed with Posgresql and hosted on bare metal servers for optimum performance. It fetches blocks live from the blockchain over websockets, and parse them instantly. When there is a latency the last parsed block is displayed at the bottom of this page.

I see spams and duplicates

There is no filtering and what you see is what's on the chain, including fakes or spammy collections. Do your own research and don't buy NFTs you're not sure about.

Love what you're doing, how can I help?

One way to help is delegating your stars to our validator ( You can also send me feature requests and ideas.

Is an API available?

A GraphQL API is now available, go read the documentation.

Will it be open source?

There is no plan to make it open source for now but it might change in the future.
