Tempo API method that returns an array of all logs matching the filter with the given ID. Unlike eth_getFilterChanges, this returns all matching logs, not just new ones since the last poll.

​
Parameters

  • filterId — the filter ID returned from eth_newFilter

​
Response

  • result — array of log objects matching the filter:
    • address — contract address that emitted the log
    • topics — array of indexed log parameters
    • data — non-indexed log parameters
    • blockNumber — block number containing the log
    • blockHash — hash of the block
    • transactionHash — hash of the transaction that emitted the log
    • transactionIndex — index of the transaction in the block
    • logIndex — position of the log in the block
    • removed — true if the log was removed due to a chain reorganization

const getFilterLogs = async () => {
    // Create a log filter
    const filterId = await provider.send("eth_newFilter", [{
      address: PATHUSD,
      topics: [TRANSFER_TOPIC],
      fromBlock: "0x560000"
    }]);
    console.log(`Created filter: ${filterId}`);

    // Get all matching logs
    const logs = await provider.send("eth_getFilterLogs", [filterId]);
    console.log(`Found ${logs.length} Transfer events`);

    for (const log of logs.slice(0, 5)) {
      console.log(`\nBlock ${parseInt(log.blockNumber, 16)}:`);
      console.log(`  Tx: ${log.transactionHash}`);
      console.log(`  From: 0x${log.topics[1].slice(26)}`);
      console.log(`  To: 0x${log.topics[2].slice(26)}`);
    }

    // Clean up
    await provider.send("eth_uninstallFilter", [filterId]);
  };
