Seer

Seer is a real-time data platform for the Cosmos ecosystem built by the Coinhall team, supplying market prices, charts, DEX aggregation and analytics for Terra and other Cosmos chains; developers read price, trade and liquidity data through its interfaces to build trading front ends and analysis tools. It addresses the growing number of Cosmos chains with market and pool data spread across each one and no unified query entry point, consolidating multi-chain data into a single layer before exposing it.

On the interface side, the Genie API serves campaign and reward scenarios, returning claimable reward information for a given user address and campaign contract, including an encrypted claim payload that the client uses to construct the on-chain execute message. Rewards come as tokens or loot boxes, and the number still unopened has to be queried from the contract and subtracted from the API figure. It is discussed as a Cosmos data aggregation and campaign interface provider.
