Private Transactions

Send private transactions on Ethereum Mainnet & BSC to protect your transaction from frontrunning bots.

What Are Private Transactions?

Private transactions bypass the public mempool and are sent directly to bloXroute’s network, where they are distributed to trusted, participating builders. This prevents frontrunning bots from accessing the transactions before they are included in a block. By submitting transactions privately, users gain enhanced protection against frontrunning and other exploitative behaviors.

Pricing:

• Private transactions no longer require additional payments to bloXroute and are available across all tiers (similar to blxr_tx) for free.

• Private transactions are automatically enrolled in the BackRunMe service, which shares 40% of the profit with searchers.

Key Notes:

• Builders may handle private transactions like public ones, except for not broadcasting them. It is the user's responsibility to set an appropriate gas price to ensure private transactions are included in the block.

• Users can employ strategies during the waiting period between submitting a private transaction and sending a public transaction. For instance, the timeout parameter can specify how long the BDN should wait for the private transaction to be executed before releasing it publicly.

• Participating builders agree not to broadcast private transactions to the peer-to-peer network. However, private transactions can still become public under certain circumstances, such as:

  • The block containing the private transaction becomes an orphan or uncle block.

• By using the Private Transactions Program, users acknowledge that complete privacy is not guaranteed.
