Feature Request: `handleTransaction`

[msgul]

Do you want to request a feature or report a bug?
Feature request.

Currently, there is handleBlock, which allows us to trigger on all incoming blocks in subgraphs, but is it possible to add a trigger for all transactions? (like handleTransaction) In this way, all blocks, transactions and addresses on the network can be indexed, so it will be possible to create explorers (like etherscan) on evm-based chains (if it is not possible to add them as a cli command as mentioned in #297). In addition, if the feature mentioned in #1211 is added, transaction information can be retrieved from the block and this feature may not be needed.

Hi! Yes this is a good request - transaction information is non trivial to fetch from the RPC, but with the addition of an Ethereum Firehose as a data source, this should become much more immediately feasible @maoueh

@azf20 is there any update on this Feature-handleTransaction , so that all transactions can be indexed, if not is there a workaround we can do in subgraph to acheive this?

hey @kumar8317 - we have made significant progress with the Firehose integration, but this data is also available directly using https://substreams.streamingfast.io/. What is your use case?

[kumar8317]

@azf20 Our use case is to index all transactions (including native coin transfers) on a custom evm type chain and then do further processing. If this can be done, could you direct me to a doc/tutorial on how to achieve this
