Most DeFi platforms today operate in the open, with every trade, order, and strategy visible to validators and anyone colluding with them. This transparency, while central to DeFi’s ethos, creates major vulnerabilities, especially for pre-trade data. Slippage tolerance, trade size, and pricing parameters are often visible to validators and MEV bots before the trade is finalized, opening the door to frontrunning and other exploits.

Darklake and Arcium are tackling this issue head-on by creating a full-stack encrypted execution layer for Solana. While Darklake’s zkAMM protects the pre-trade layer using zero-knowledge proofs, Arcium complements this by enabling multi-party computation (MPC) for shared private state, ensuring not just pre-trade privacy to avoid malicious MEV but also post-trade privacy. Together, we close the privacy gap in DeFi.‍

Alarming Data on MEV Extraction

Recent data highlights the urgent need for these privacy solutions. In just 29 days, a staggering 18,409 SOL ($2.76M) was silently extracted across 186,159 attacks on Solana through platforms like Raydium and Pumpfun. This level of extraction represents a massive loss for traders, underscoring the necessity of Darklake and Arcium’s collaboration to protect users from predatory behavior.

Darklake: A zkAMM Protocol for Frontrunning-Resistant Trading

Darklake is building a zkAMM (zero-knowledge automated market maker) that protects users from pre-trade data leakage. By encrypting critical trade inputs like slippage, order size, and price preferences before they hit the blockchain, Darklake ensures that neither validators nor malicious actors can exploit that data for profit.

The protocol relies on zero-knowledge proofs to verify the validity of trades without exposing sensitive parameters. This offers users peace of mind: no more sandwich attacks, and no more leaking alpha to bots.

Key Use Cases: How Arcium Enhances Darklake

By integrating Arcium’s MPC network, Darklake takes its privacy stack to the next level. While zkAMMs protect user-specific inputs before execution, Arcium enables shared private state computation—the foundation for collaborative, multi-user privacy in financial applications.

With Arcium, Darklake unlocks use cases such as:

• Dark pool order books where trades happen without exposing bids or asks to validators.
  
• Confidential AMMs enabling fully private onchain trading, going beyond zkAMM solutions (which are focused on providing pre-trade privacy and MEV protection) by adding complete post-trade confidentiality.
  

This collaboration enables both parties to do what they do best:

• Darklake secures the execution logic of private trades.
  
• Arcium powers the encrypted coordination between multiple users, orders, or strategies for dark pools and post-trade execution for completely confidential onchain trading.

Together, Darklake and Arcium deliver a robust, tamper-resistant privacy layer designed to scale seamlessly to sophisticated trading use-cases, without compromising on composability, performance, or user experience.

What’s Next: Building the Privacy Stack for a DarkFi Future

With Arcium’s MPC infrastructure, Darklake gains a strong foundation for privacy-focused trading on Solana. This integration brings a new level of data confidentiality, empowering users to trade securely and privately.

In this framework, MEV bots cannot front-run data they cannot observe and users gain the assurance to trade with privacy intact.

This partnership supports a forward-thinking approach to financial privacy, embedding confidentiality as a core component of market structure.

This is the LunarPunk vision in action: privacy not as a patch, but as a fundamental layer of market architecture.
