eth_sendRawTransaction

Introduction to eth_sendRawTransaction of BlockRazor BSC Fast mode and integration methods

Introduction

eth_sendRawTransaction is a Fast mode transaction sending interface provided by BlockRazor for BSC. It is compatible with the standard eth_sendRawTransaction method and is used to send signed transactions with lower latency.

Transactions sent to Fast mode eth_sendRawTransactionare not broadcast through the public mempool, thus improving sending speed while preventing transactions from being exposed during public propagation.

Fast Mode is not tied to the subscription plan, but each transaction sent in Fast Mode must include a tip sent to the address 0x9D70AC39166ca154307a93fa6b595CF7962fe8e5. The minimum tip amount is the greater of 0.000025 BNB or Transaction Fee * 5%.
