Range-Bound Stability Subgraph

Purpose

This repository contains code to deploy a subgraph that indexes events related to OlympusDAO's Range-Bound Stability.

Contracts

This subgraph indexes events from the following contracts:

• Range
• Price

Where relevant, additional data/context from the contract is included in the indexed data.

It currently indexes the contracts on the Goerli testnet. However, it will be shifted to Ethereum mainnet upon final deployment.

RBS Updates

When a new RBS version is launched, the following steps must be taken to update the subgraph:

• Define a new data source in subgraph.yaml for any of the affected triggers.
  • Generally, this will just be a new version of the Heart policy. Add the new contract address and set the startBlock to be the deployment block.
  • If any of the other triggers (RANGE, PRICE at the time of writing) have had new versions deployed, add new data sources for them too.
• If the ABI/interfaces for any dependencies has changed, add the new ABI (with a version indicator), and ensure that the relevant data sources use that ABI.
• If the Operator policy has changed, update the getOperatorContract function to return the new Operator contract address at the activation (not deployment) block.
• Bophades modules that are used (RANGE, PRICE, TRSRY) for data lookup are accessed using the Bophades kernel, so do not need the addresses or starting blocks.
• Adjust the base contract and starting block for grafting, as re-indexing can take a long time.
• Bump the version number in .subgraph-version.
• Deploy to Subgraph Studio using yarn deploy:studio.
• Let the new version re-index and confirm that it indexes events from the new version.
• Publish to the Decentralized Network using the Subgraph Studio interface.
