Transaction boost

Transaction boost is only available for Ethereum transaction.

Transaction boost is a brand new feature allowing wallets to make sure they always land in the next block at the best possible position on Ethereum while maximizing revenue. There are two types of boosts that can be activated independently.

Bundle Boost

Guarantees best positioning.

Non-exclusive transaction will automatically be discarded for bundle boost inclusion.

Every block, merkle creates a priority bundle with all merkle exclusive transactions. The priority bundle is then broadcasted to every major block builder. We discount just enough priority fee such that the position of the bundle is not impacted while maximizing the revenue our customers receive.

How to activate: Add ?boost to the RPC url.

Mempool Boost

Guarantees best inclusion.

Important drawbacks: Make sure the transaction is protected by a built-in block limit, otherwise the transaction might be sandwiched in the next MEV-Boost enabled block. If you are not sure if mempool boost is beneficial for you, talk to us. Typically, only advanced trading system (not wallets) use this feature.

About 9% of all Ethereum blocks are not powered by MEV-Boost and therefore are missed by private mempools. merkle monitors Ethereum to detect whenever the next block is not MEV-Boost powered. A transaction with Mempool Boost activated will be injected in the public mempool via our network of mempool nodes around the globe.

This boost triggers when:

• The next slot's validator is not registered on any major relays.

• The next vaildator has never missed any slots. If the validator is known for missing slots, it's highly likely the next slot will be skipped and result in the next block being MEVBoost-powered.

How to activate: Add ?mempool_boost to the RPC url.
