Benefits of MEV bundling

Riskless Transactions

When a bundle reverts, you don't end up losing any gas. There is literally no reason to go for hyped drops where there is a lot of uncertainty, without running a bundle (simultaneously with mempool transactions if you may). Ever.

Stealth Gas

Bundles are sent to a private mempool, which hides your gas settings. This prevents yourself from being frontrun by other bots and avoids contributing to the conventional public mempool gas war.

Avoid Tedious Gas Calculations

You can choose to pay the transaction fee directly in ETH instead of priority fees, by specifying a bribe transaction.

Guaranteed Transaction Ordering

Unlike regular transactions that propogate independently through the Ethereum network, transactions in a bundle are included sequentially. Meaning that you are more likely to see all your transactions included vs independent public mempool transactions where some transactions may propogate late.

Innovative Use Cases

Signature minting
Whitehat assets recovery
Katana V2 (contract minting) bundling with Flip State

Integration

Mint tasks now push MEV Bundles natively in parallel with your normal mint txn

Now your txns can race, one with a mev bundle, and a backup pushing a normal mint txn
If your MEV bundle fails, your normal txn will still push through, while losing 0 gas on the failed MEV bundle.
Since the transactions in the bundle contain the same nonce as the transactions sent regularly to the public mempool, there is no possibility to "double-spend" or interfere with each other. Either your bundle is included, and your public mempool transactions are dropped (ignored entirely), or the bundle is not included and your public mempool transactions compete as normal with the rest of the market.

Alternatively, users can choose to only push MEV bundles in the mint task's Execution settings

This allows users to compete in mints truly risk-free by utilizing the benefits of MEV
If any of the transactions in the bundle fail, the entire bundle will be invalidated. There will be no lost gas.
- Note that a single bad transaction in the bundle that is destined to revert/fail will invalidate your entire bundle. It's imperative you do pre-flight checks (covered in the next page).

In this beta period, MEV Bundles cannot be sped up. If you choose to use Bundle Only, you will forfeit the ability to speed up your transaction if you didnt push enough gas. If it is unticked, only mempool transactions will be sped up.
