datanexus-indexer

The Data Nexus team has been a stakeholder since the launch of the mainnet. Our operation runs an indexer to supply query demand and subgraph development shop to help expand the protocol's query capacity. 

Official Subgraph for Silo Finance, subgraph includes the markets ("silos") and related indexed data.

Opyn is a capital efficient DeFi options protocol that allows users to buy, sell, and create options on ERC20s. DeFi users and products rely on Opyn’s smart contracts and interface to hedge themselves against DeFi risks or take positions on different cryptocurrencies. Opyn v2 is built using Gamma Protocol, a capital efficient options protocol that allows DeFi users to trade option spreads and combos, create flash mints, auto-exercise at expiry, and create new options. Developers can take advantage of Gamma's operator function, which allows an address to update an account's positions on behalf of the account. Operators play critical role in the protocol, enabling products such as options rollover contracts, portfolio managers, auto-minting, and AMMs to be built on top of Gamma.

The Graph is a protocol for indexing and querying data stored on blockchain networks. Anyone can build and publish open APIs, called subgraphs, making data easily accessible. This subgraph keeps track of all activity taking place on the protocol by the various participants: indexers, subgraph deployers, curators, delegators, and queries. 

Premia's automated options market enables best-in-class pricing based on realtime supply and demand, providing fully-featured peer-to-pool trading and capital efficiency to DeFi options.
