BSC submit arbOnly

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

Bundle Submission Details

• Method: submit_arb_only_bundle (Cloud API)

• Endpoint: Available only via backrunme.blxrbdn.com

• Persistence: Bundle will persist until it is landed or no longer valid. There is no need to specify target block numbers or send the same bundle multiple times.

• Bundle Pricing: Bundles can have zero bundle price (i.e., 0 gwei gasPrice).

• MEV Revenue Sharing: Searchers must share extracted arbitrage rewards with Bloxroute via an internal transaction or a separate direct transfer to bloXroute's smart contract:

  • Smart Contract Address: 0x6374Ca2da5646C73Eb444aB99780495d61035f9b

• Bundle Prioritization:

  • If multiple conflicting bundles reference the same target transaction, the bundle sending the higher amount to the smart contract will be prioritized.

  • Recall that sending an amount to the smart contract is weighted higher than gas payments. The bloXroute builder employs the following high-level prioritization formula:

  [(∑(Gas Fee of searcherTX)×0.9)+(BNB sent to dynamic fee wallet)]
