ETH Private Transactions
Send private transactions on Ethereum Mainnet to protect your transaction from frontrunning bots.
Ethereum Mainnet
The blxr_private_tx
endpoint allows users to send a single transaction that is added directly to the blocks generated by block builders.
Pricing: Private txs no longer require extra payments to bloXroute and can be used by all tiers (similar to blxr_tx) for free. In addition, private txs are automatically enrolled in the BackRunMe service and will pay back searchers 40% of the profit.

Parameters
transaction
[Mandatory] Raw transaction bytes without 0x
prefix.
timeout
[Optional] An integer value that represents the time, in seconds, needed to wait for a Private Transaction to be included in a block. If omitted, it defaults to 0. If timeout
is not 0 and the transaction is not mined after the timeout value, it will be sent publicly. If the timeout
is 0, no public transaction will be sent.
mev_builders
[Optional, default: bloxroute
builder] A dictionary of MEV builders that should receive the private transaction. Please provide empty string as signature for each builder. Possible MEV builders are:
bloxroute
: bloXroute internal builderflashbots
: flashbots builderall
: all builders
node_validation
[Optional, default: false] Transaction would be validated by a blockchain node, and Cloud-API returns an error message (e.g. "invalid sender" or "nonce too low") in case the raw transaction byte fails validation check.
[Optional, default: False] A boolean flag indicating if the bundle should be sent just to a single block builder who is participating in the priority fee refund program. Please refer to Priority Fee Refund for details of the priority fee refund program.
refund_recipient
[Optional] A string representing the wallet address to receive refund when priority_fee_refund
flag is enabled.
