v2.3.0

What's Changed

Wildcard Indexing ⁂

Index the whole chain by event signature without specifying exact contract addresses.

Here's an example of indexing all ERC20 Transfer events. No need to change the config file. Simply add the wildcard: true option to the second argument in your handler:

ERC20.Transfer.handler(
  async ({ event, context }) => {},
  {
    wildcard: true,
  }
)

Final touches implemented by @JonoPrest in #171, #197

Event Filtering 🔎

Filter events by indexed parameters. Simplify your handler's logic or get new indexing possibilities when joined with the Wildcard Indexing feature:

UniswapV3Factory.PoolCreated.handler(async ({ event, context }) => {},
  {
    wildcard: true,
    eventFilters: [{ token0: DAI_ADDRESS }, { token1: DAI_ADDRESS }],
  },
);

⚡ Both Wildcard Indexing and Event Filters are currently only supported with HyperSync. We are working on adding support for RPC mode in the following versions.

Implemented by @JonoPrest

Fuel Merge ⛽

The fuel ecosystem indexer is integrated into the main repository code. This was a huge refactoring which came with a big list of benefits and a big list of opportunities.

If you use [email protected] version, you can switch to [email protected] and get:

• Now Fuel and Evm reuse the same code. This gives V2 API, much better test coverage, and many improvements/fixes compared to [email protected]
• Support for raw_events configuration
• Support for Wildcard Indexing
• Public repository
• Active development and maintenance

Talking about opportunities, this unblocks:

• Adding support for Mint/Burn/Call/TransferIn/TransferOut events
• Indexer became more modular and library-like, simplifying the integration of new ecosystems in the future

Implemented by @DZakh in #186, #190, #192, #193, #194, #196, #202

Other 🏗️

• Add validation for end block on finite chains by @JonoPrest in #191
• Upgrade Hasura to latest v2 release by @JonoPrest in #169
• Use the local envio package for testing instead of defaulting to latest by @DZakh in #200
• Fix panic on null exn passed to error handling by @DZakh in #203
