ONEverse Subgraph

Built on top of HORIZON BRIDGE SUBGRAPH

• https://github.com/harmony-one/horizon-bridge-subgraph

Prerequisites

• Run graph node locally using docker-compore up or point to https://graph.t.hmny.io:8020/ as described in docs.harmony.one
• yarn codegen
• yarn build
• yarn create-local or npm run create-local
• yarn deploy-local or npm run deploy-local

This subgraph dynamically tracks assets and events

• aggregated data across managers, assets and wallets
• data on individual assets
• data on transactions
• data on managers
• data on wallets

Queries

Below are a few ways to show how to query the horizon-bridge-subgraph for data. The queries show most of the information that is queryable, but there are many other filtering options that can be used, just check out the querying api. These queries can be used locally or in The Graph Explorer playground.
