Overview

Introduction

Scutum is an RPC product that provides users with MEV protection and supports refunds.

Transactions submitted by users, if processed by regular RPC, will be publicly broadcasting between node P2P networks. Transactions are extremely vulnerable to MEV attacks, resulting in the potential rebate space generated by transactions being squeezed out.

Compared to regular RPC, transactions submitted to Scutum will be kept in a private channel, thus resisting MEV attacks of sandwich and frontrunning. And Scutum supports users to customize the disclosure of transaction data, and the generated profit will also be refunded to users in real-time.

Use case

Trader

For users who frequently send transactions on DEX, there is a high probability of exchanging the target cryptocurrency reaching the slippage limit, resulting in invisible losses. Traders can go to Scutum's MEV Protect RPC General for Wallet User and add the RPC to the wallet with one click. SWAP transactions sent from then on can be deeply protected by Scutum, reducing slippage losses, and can receive transaction refunds in real time with a certain probability.

Scutum can provide MEV protection and transaction refunds for orderflow projects. In addition, due to gas fees of backrun transaction, fast inclusion of transactions sent by project is supported, thus improving the trading experience.

FAQ

How can transactions receive refunds while resisting MEV attacks?

• The transactions are shared with Searchers according to custom disclosure. Searchers can only perform harmless backrun strategies on transactions, thereby not only defending against sandwich and front-running attacks but also refunding the profits generated from backrun to users.

When and in what form will I receive the refund?

• If there is an opportunity to execute the backrun strategy for the transactions submitted by the project, the refund is completed by the Searcher calling the smart contract in real-time, meaning that the refund transaction and the project transaction will be successfully executed within the same block.

Will the transactions be reverted?

• If Scutum detects that a transaction will revert and its revert protection is enabled, it will not be included in the block.

How are profits distributed among various roles?

• If there is profit margin in the transaction and it is included in the block after the bid is successful, Scutum will refund 90% of the bid to the user, and the remaining 10% will be used to pay Scutum's handling fee and the other part will be used to pay the builder for bribe to get the transaction included in the very next block.
