  formatter: Formatter {
    formats: {
      transaction: [Object],
      transactionRequest: [Object],
      receiptLog: [Object],
      receipt: [Object],
      block: [Object],
      blockWithTransactions: [Object],
      filter: [Object],
      filterLog: [Object]
    }
  },
  anyNetwork: false,
  _networkPromise: Promise { <pending> },
  _maxInternalBlockNumber: -1024,
  _lastBlockNumber: -2,
  _maxFilterBlockRange: 10,
  _pollingInterval: 4000,
  _fastQueryDate: 0,
  connection: {
    url: 'https://polygon-mumbai.infura.io/v3/********************************'
  },
  _nextId: 42
}
