Zizou 12369c3981 fix: update get_block_storage_changes to correctly emit previous value (#280)
Before this commit we were using the latest `ContractSlot` for both previous and new value. This is not correct because if the value changed twice we would have the middle value emitted as "previous". For example if a value was changed like this in a single transaction 1 -> 10 -> 2 we would have `new_value=2` and `previous_values=10` while the previous value was actually 1.

Substreams Indexing Integrations

Please refer to the official Substreams Indexing docs.

Release

To release a package simply tag a commit with the package name and its version: e.g. ethereum-balancer-0.1.0. This will create a release and automatically build and push the spkg into our registry.

Note

The CD pipeline will error if the Cargo version is not the same as the version in the tag.

Releases are immutable so do not try to delete tags or build the same release twice since this will error.

Pre-release

To create a pre-release for testing in dev you can start CD pipeline manually supplying the package you'd like to pre-release. This will create a [package].pre-[commit-sha] release in our spkg repository which you can use to run the substream.

For forked protocols you'll need to also supply the config file name, e.g. ethereum-pancakeswap.

Test your implementation

To run a full end-to-end integration test you can refer to the testing script documentation.
