BSC Mempool Stream

Any Bitquery GraphQL stream can be converted to a mempool monitoring stream by setting mempool: true We also provide low-latency Kafka streams to monitor broadcasted data, which are much faster than GraphQL mempool streams. Read more here

How do we simulate txs for Bitquery Mempool APIs & Streams?​

When a transaction is received by the node but not yet included in a block, Bitquery uses the following context to send mempool data:

  • The transaction is executed in the EVM (using the current pending block context).

  • The system captures the simulated receipt and trace.

For each batch of simulated transactions, Bitquery records the block header used as the execution context.

message BroadcastedTransactionsMessage {
  Chain Chain = 1;
  BlockHeader Header = 2;
  repeated Transaction Transactions = 3;
}
