ETH submit arbOnly

The BackRunMe bundle submission system on Ethereum allows searchers to submit arbitrage bundles referencing private transactions from the ETH arbOnlyMEV stream. These bundles must strictly backrun the target transaction (from the stream) and cannot be used for frontrunning.

Profit-Sharing Model

Revenue from extracted arbitrage is distributed as follows:

• 40% to the original private transaction sender

• 15% to Bloxroute

• 5% to the block proposer/miner

Simulation Support

Use simulate_arb_only_bundle to verify bundle validity before submission.

Access & API Endpoint

• Method: submit_arb_only_bundle (Cloud API)

• Endpoint: Available only via backrunme.blxrbdn.com

• Wallet Info: To retrieve the address of the Bloxroute ETH wallet, use the blxr_info endpoint.

REQUEST

Parameters

Parameter	Description
transaction_hash	Trigger transaction hash
transaction	A list of raw transaction bytes without a 0x prefix that are meant to immediately follow the trigger transaction.
block_number	Block number of a future block to include this bundle in, in hex value. For traders who would like more than one block to be targeted, please send multiple requests targeting each specific block.
min_timestamp	[Optional] the minimum timestamp that the bundle is valid on, an integer in unix epoch format. Default value is None.
max_timestamp	[Optional] the maximum timestamp that the bundle is valid on, an integer in unix epoch format. Default value is None.
