title: trouble getting pending transaction receipt for Binance Smart Chain
body: <p>I can not get transaction receipt for BSC chain. I tried 3 different approaches but I failed.</p>
  <p>Here is my code:</p>
  <pre><code>def get_transaction_recipt(txid):
      recipt = web3.eth.getTransactionReceipt(txid)
      print(recipt)
  
  async def get_event():
      async with connect('wss://bsc.getblock.io/mainnet/?api_key=&lt;api-key&gt;') as ws:
          await ws.send('{&quot;id&quot;: 1, &quot;method&quot;: &quot;eth_subscribe&quot;, &quot;params&quot;: [&quot;newPendingTransactions&quot;]}')
          subscription_response = await ws.recv()
          print(subscription_response)
  
          while True:
              try:
                  message = await asyncio.wait_for(ws.recv(), timeout=60)
                  txid = (json.loads(message)['params']['result']) # 
  
                  threading.Thread(target=get_data, args=[txid]).start()
                  pass
              except:
                  pass
              
  if __name__ == &quot;__main__&quot;:
      loop = asyncio.get_event_loop()
      while True:
          loop.run_until_complete(get_event())
      
  </code></pre>
  <p>I can get new pending Transaction hashes but i get error calling get_transaction_recipt function</p>
  <p>this is the error</p>
  <pre><code>web3.exceptions.TransactionNotFound: Transaction with hash: &lt;TransactinHash&gt; not found.
  </code></pre>
  <p>I also tried</p>
  <pre><code>web3_pending_filter = web3.eth.filter('pending')
  while True:
     transaction_hashes = web3.eth.getFilterChanges(web3_pending_filter.filter_id)
  </code></pre>
  <p>but the result was empty list</p>
  <p>I also tried this code:</p>
  <pre><code>list_of_block_transactions = web3.eth.getBlock('pending', full_transactions=True).transactions
  for transaction in list_of_block_transactions:
     get(transaction)
  </code></pre>
  <p>and I got list of latest block transaction in list_of_block_transactions. NOT PENDINGS!!</p>
  <p>but when trying with ETH blockchain the result was ok and returned me with all transaction receipts</p>
