# eth_getLogs | Arc

> Arc API method that returns an array of logs matching a filter object. This is commonly used to track events emitted by smart contracts.

Arc API method that returns an array of logs matching a filter object. This is commonly used to track events emitted by smart contracts, such as TIP-20 token transfers.

## Parameters

* `filterObject` — the filter object:
  * `fromBlock` — (optional) block number (hex) or tag to start from
  * `toBlock` — (optional) block number (hex) or tag to end at
  * `address` — (optional) contract address or array of addresses
  * `topics` — (optional) array of topic filters

## Response

* `result` — array of log objects:
  * `address` — contract address that emitted the log
  * `topics` — array of indexed log parameters
  * `data` — non-indexed log parameters
  * `blockNumber` — block number containing the log
  * `transactionHash` — hash of the transaction that emitted the log
  * `logIndex` — position of the log in the block

## `eth_getLogs` code examples

The following example retrieves Transfer events from the pathUSD token:

<CodeGroup>
  ```javascript ethers.js theme={"system"}
  const ethers = require('ethers');
  const NODE_URL = "CHAINSTACK_NODE_URL";
  const provider = new ethers.JsonRpcProvider(NODE_URL);

  // pathUSD token address
  const PATHUSD = "0x20c0000000000000000000000000000000000000";
  // Transfer event topic
  const TRANSFER_TOPIC = ethers.id("Transfer(address,address,uint256)");

  const getLogs = async () => {
      const logs = await provider.getLogs({
        address: PATHUSD,
        topics: [TRANSFER_TOPIC],
        fromBlock: "latest"
      });

      for (const log of logs) {
        console.log(`Transfer in tx: ${log.transactionHash}`);
      }
    };

  getLogs();
  ```

  ```python web3.py theme={"system"}
  from web3 import Web3

  node_url = "CHAINSTACK_NODE_URL"
  web3 = Web3(Web3.HTTPProvider(node_url))

  # pathUSD token address
  PATHUSD = "0x20c0000000000000000000000000000000000000"
  # Transfer event topic
  TRANSFER_TOPIC = web3.keccak(text="Transfer(address,address,uint256)").hex()

  logs = web3.eth.get_logs({
      'address': PATHUSD,
      'topics': [TRANSFER_TOPIC],
      'fromBlock': 'latest'
  })

  for log in logs:
      print(f"Transfer in tx: {log['transactionHash'].hex()}")
  ```

  ```bash cURL theme={"system"}
  curl -X POST "CHAINSTACK_NODE_URL" \
    -H "Content-Type: application/json" \
    -d '{
      "jsonrpc": "2.0",
