Ethermine Pool Launches “Private” Transactions Without Public Mempool – Bits Media

The Ethermine Pool Team has added a "private" transaction feature to improve trading efficiency on DEX. Its support is already present in the Metamask wallet.
According to
Ethermine team announcement, Added the Private Remote Procedure Call Endpoint for Ethereum function to the pool toolbox (ETH). Таким образом трейдеры платформ DeFi могут настроить проведение транзакций с токенами исключительно через серверы Ethermine и блоки, mined by the pool itself, without their live broadcast to the public network. This will avoid intercepting transactions and reduce the impact of MEV..

If the function is enabled, user can send transactions directly from Ethermine nodes, making them unavailable to the shared memory pool. To make a transfer, you need to select "Custom RPC" in Metamask and configure the data endpoint to the Ethermine server. This is how experienced traders can significantly reduce commissions., the effect of "slippage" of orders and the possibility of intercepting transactions by MEV bots. RPC Ethermine has already been implemented in the popular Ethereum wallet Metamask.

"Private" transactions will be included in the first free block, mined by the Ethermine pool. but, if it will be "Uncle Block", then transactions from it can leak into the shared memory pool. The risk of such leakage does not exceed 5%, but still it should be taken into account.

Recall, that recently a large ether mining pool, Sparkpool, was forced to close all services for Chinese customers due to new restrictions in the country. The same situation happened with the Bitcoin mining pool F2Pool.
