Gravity Info Dashboard

This repo contains frontend and backend code for deploying a Gravity information server, this server queries public full nodes and processes data about the chain in order to present the page https://info.gravitychain.io in addition to this page public API endpoints are provided

This server computes and displays info that would be otherwise difficult to access or compute. Such as daily and weekly bridge volume, vesting info, and parsed out transfer destinations.

Issues and pull requests for new endpoints or information formats are welcome.

The repo auto-deploys the most recent commit in main to https://info.gravitychain.io

API Docs

/bridge_volume

Provides monthly, weekly, and daily volume information for Gravity Bridge. The value of all bridged tokens is converted to USDC and summed. Units here are in whole USDC. This endpoint is updated once a day.

/erc20_metadata

Provides a list of every ERC20 that is in the Gravity Bridge solidity contract along with symbol + decimals metadata. If this ERC20 has a Uniswap v2 or v3 pair an exchange rate is provided. The exchange rate is the amount of USDC 1 unit of the input token would buy. For example UNI below has a value of "exchange_rate": "7259165" meaning 1 UNI is worth 7259165 base units of USDC. Since USDC is a 6 decimal token we divide by 1*10^6 and get $7.25. This endpoint is updated every 30 seconds and does not rate limit queries.
