EVM ERC-20 Transfers

The EVM ERC-20 Transfers template tracks ERC-20 Transfer(address,address,uint256) events. Source: evm-erc-20-transfers

​
Data Type

This template uses BlockWithLogs. It reads stream.logs.

​
Configuration

  • TOKEN_ADDRESS: Optional token contract filter.
  • FROM_ADDRESS: Optional sender address filter.
  • TO_ADDRESS: Optional recipient address filter.
  • MIN_VALUE: Optional minimum amount.
  • MAX_VALUE: Optional maximum amount.
  • DECIMALS: Optional token decimals for human-readable thresholds.

​
Logic

The filter:
  • Matches the ERC-20 Transfer event topic.
  • Parses logs with ethers.Interface.
  • Compares token amount thresholds.
  • Treats min and max as raw base units if DECIMALS is omitted.
  • Returns null when no transfer matches.

​
Output

When at least one log matches, the feed returns a result with the matching ERC-20 transfers inside transfers. 
{
  "metadata": {
    "networkId": "ethereum-mainnet",
    "blockNumber": "123",
    "isReorg": false
  },
  "count": 1,
  "transfers": [
    {
      "hash": "0x...",
      "from": "0x...",
      "to": "0x...",
      "value": "1000000000000000000",
      "address": "0x..."
    }
  ]
}
value is the raw token amount from the ERC-20 event. If no log matches the configured token, sender, recipient, or value range, the filter returns null and the feed does not emit a result.
