How do I get all the logs for a given transaction, across all contracts executed in the transaction?

Hi,

I'm trying to piece together some data from Uniswap v3 positions. Uniswap v3 'add' and 'remove' liquidity transactions emit a bunch of logs. Some of these are emitted by the Uniswap Positions NFT contract, but others are emitted by the ERC-20 token contracts involved in the pool we're adding to/removing from.

Example 'add' transaction logs: https://etherscan.io/tx/0x3766f3eccfdd6c8ad9fde50f6496dcc15a0988063e5493651d6f4fdbe7590aa5#eventlog

Example 'remove' transaction logs: https://etherscan.io/tx/0x74aa183831ed9dd9672807c6768b570e11e3c9700d3ad151e315bfc8000a83ee#eventlog

Suppose I have a list of transaction hashes, some of which are 'add' and 'remove' transactions. How do I get the full set of logs for each transaction? Here's what I can filter by when calling provider.getLogs():

export interface EventFilter {
    address?: string;
    topics?: Array<string | Array<string> | null>;
}

export interface Filter extends EventFilter {
    fromBlock?: BlockTag,
    toBlock?: BlockTag,
}

export interface FilterByBlockHash extends EventFilter {
    blockHash?: string;
}

It looks like there's no way to filter by transaction hash. I can iterate through my transactions and get the block numbers. But I still need to call getLogs() once for each address that might emit logs as part of the transaction, with fromBlock and toBlock both set to the block number of my transaction. When iterating through the logs from an ERC-20 Transfer event, it's hard to then marry that up with the logs from the Uniswap Positions NFT for the same transaction.

Am I missing a trick here?

If you have the transaction hash, you can use provider.getTransactionReceipt(hash). To parse all the events into Event objects, you can use tx.logs.map((log) => contract.interface.parseLog(log)).

It might make sense in v6 for me to add a contract.queryTransaction(hash) method. I've added a stub for now to investigate further. :)

OMG face palm. Too easy. Thank you so much for the prompt reply. Ethers.js is awesome.
