Project Builder

RPC Endpoint

The project builders could send bundle to the Endpoint Exclusive for Project

https://bsc.blockrazor.xyz

Request parameters

On BSC, eth_sendMevBundle allows transactions with 0 gwei in the bundle, but the average gasPrice of transactions(excluding those from the public mempool) in the bundle must still be no less than 0.05 gwei. Since head builders of BSC have a preference for this model, it is recommended to construct transactions with 0 gwei.

Bundle

Parameters	Mandatory	Format	Example	Remark
txs	mandatory	[]bytes	[ "0xf84a……e54284" ]	raw txs, up to 50 transactions allowed to be set
revertingTxHashes	optional	[]hash	["0x1f23……0abb1e"]	Transactions that allow to be reverted, a subset of txs
maxBlockNumber	optional	uint64	39177941	The maximum block number for the bundle to be valid, with the default set to the current block number + 100
