Encrypt the Mempool,
End Malicious MEV

Shielded Trading makes MEV attacks virtually impossible and minimizes censorship to its lowest possible level.

The Billion DollarDrain:

MEV, Censorship, and the Illusion of Fair Trading

Since 2020, over $1.8 billion has been lost to MEV on Ethereum, largely at the expense of everyday users. This isn’t just a byproduct of market dynamics; it’s the result of specialized bots and validators seeing pending transactions and exploiting them for profit.

Centralized fixes for MEV attacks have created new risks and made the problem worse. Shielded Trading, powered by a distributed encrypted mempool, stops manipulation at the source—ensuring protection for all.

Shielded Transactions

Set up Shielded Trading on Gnosis Chain to enjoy protection against malicious MEV and censorship. Simply add a custom RPC to your wallet.

Add RPC to MetaMask Add Manually

Important: Current Limitations and Risks for Mainnet Implementation. While it’s a full mainnet implementation, there are currently a limited number of participating validators and Keypers, which may lead to longer transaction inclusion times. Additionally, there’s still a trust assumption with the RPC, and validators are not yet subject to slashing. In rare cases, some transactions may fail to be included in a block due to validator issues or re-orgs, and while these will be re-sent by the inclusion service, they could become vulnerable to front-running since their keys may already be released.

Get Protected on Another Chain

Shielded Trading is currently only live on Gnosis Chain, but it will soon be available on other chains.

How Shielded Trading Protects You Using Threshold Encryption

Transaction Encryption

Your transaction is encrypted with a DKG-generated key via a decentralized group of Keypers before it enters the public mempool, which is a waiting area for transactions.

Preventing Manipulation

Attackers can’t see your encrypted transaction, making it nearly impossible for them to front-run or disrupt your trades.

Decentralized Decryption

Once the block producer or sequencer confirms inclusion and ordering for your transaction, the decentralized group of Keypers generate the decryption key for your transaction, which is then decrypted and processed as normal.

A Distributed Solution to a Centralized Problem

Shielded Trading employs decentralized threshold encryption — a form of MPC (Multi-Party Computation). Multiple parties known as Keypers are required to decrypt transactions, making collusion more difficult. It's the ideal solution for both protecting users and preventing the centralized concentration of power.

Encrypted Mempools are Essential

Martin Köppelmann

Gnosis

…more systemic solutions are necessary for credible neutrality. On Gnosis Chain, we have deliberately not build MEV-boost infrastructure and instead are working first with Shutter on a solution to include transactions in the chain while they are still encrypted.

One technology that is crucial to the successful implementation of many of these designs (specifically, either BRAID or a version of APS where there are strict limits on the capability being auctioned off) is encrypted mempools.
