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.

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.

/supply_info

Provides a breakdown of vesting versus non-vesting tokens for Gravity Bridge, value returned are in ugravition and must be divided by 1*10^6 to display whole tokens. This value is updated once a day.

• total_supply: The total supply of tokens in existance.
• community_pool: The total amount of tokens in the community pool subject to use by governance vote
• total_liquid_supply: All tokens that are not vesting and not in the community pool, this includes staked tokens and unclaimed staking rewards.
• total_liquid_balances: Tokens that are avaialble to be sent immeidately, so tokens that are not staked and not vesting.
• total_nonvesting_staked: These tokens are liquid (eg not vesting) and currently staked.
• total_vesting: A sum of all tokens that are not yet vested but will become liquid at some point in the future.
• total_vesting_staked: All tokens that are vesting and also staked
• total_vested: The amount of tokens that where once vesting but are now liquid

/batch_tx/{batch_nonce}

Takes the url encoded batch nonce as a request value and builds the required ETH transaction payload to relay this batch. Note the return value of this endpoint is the 'data' field of the Ethereum transaction. The rest of the transaction is up to your application to fill out and send.
