Darklake X Arcium: Encrypted Execution
Darklake and Arcium have partnered to bring encrypted DeFi execution to Solana, combining Darklake’s zkAMM for private trade inputs with Arcium’s MPC runtime for secure multiparty coordination. This integration eliminates mempool exposure, slippage signaling, and validator front-running, enabling confidential trading, dark pools, and privacy-preserving auctions. Built on Solana’s fast, parallel architecture, the solution restores strategic edge for traders, filters toxic flow for LPs, and unlocks a new design space for private, composable DeFi.
The Problem: DeFi’s Pre-Trade Exposure
DeFi has always worn its transparency like a badge of honor. But transparency, when unconditional, comes at a price.
Today, every trade in DeFi telegraphs its intent to the network before it’s finalized. Order size, price tolerance, routing preferences, these signals leak into the mempool, ripe for exploitation. Validators, bots, and MEV searchers watch closely, ready to reorder, simulate, or front-run. The result? Honest traders suffer degraded execution, and LPs are inundated with toxic order flow.
The scale of the problem is no longer theoretical. In just 29 days, attackers extracted over 18,000 SOL (nearly $2.7M) via MEV-style exploits on Solana alone. Sandwich attacks on platforms like Raydium and Pumpfun surpassed 186,000 incidents.
This is a fundamental flaw in DeFi’s current design. We’ve accepted this leakage as the tradeoff for composability. But we no longer have to.
Enter Darklake x Arcium: A New Execution Layer for DeFi
At the core of this collaboration is a shared conviction: DeFi must evolve beyond passive transparency into intentional, composable privacy. Darklake and Arcium are two purpose-built organizations that are aligned in mission, distinct in capability, and working together to close the privacy gap in DeFi’s execution layer.
Darklake brings encryption to the heart of trading. By sealing trade inputs with zero-knowledge proofs, Darklake ensures that slippage, sizing, and price logic remain completely private. Your intent will never be exposed to the mempool, never visible to validators. This is the first line of defense, protecting the trade itself.
But encrypting individual trades isn’t enough. Coordination between traders, LPs, pricing engines, and routing protocols must also remain private and composable.
Arcium delivers the missing piece. Its encrypted multiparty computation (MPC) runtime enables secure coordination across participants without compromising privacy. Whether it’s matching orders, routing liquidity, or settling auctions, Arcium provides the shared encrypted state required to make private execution collaborative at scale.
Together, Darklake and Arcium will create a core architectural upgrade.
What Private Execution Really Means
This partnership is about redefining execution itself, not just privacy as a feature. Here’s what encrypted coordination looks like in practice:
- No mempool leakage — Trade data is hidden from submission to settlement.
- No slippage signaling — Order logic remains confidential throughout execution.
- No validator advantage — Even block producers can't extract pre-settlement data.
- Composable encrypted state — Enables dark pools, OTC markets, and privacy-preserving auctions.
We are building a full foundational shift, not just in defense against MEV, but in the design space for DeFi itself.
Why Solana. Why Now.
Solana’s architecture is fast finality, high throughput, and parallel execution. This makes it uniquely capable of supporting encrypted coordination at scale. But, as the MEV landscape on Solana matures, with increasingly sophisticated routing and block construction strategies, the urgency for native privacy infrastructure has never been greater.
This partnership marks a pivotal moment:
- For traders, it restores informational edge and protects execution strategy.
- For LPs, it filters out toxic flow and delivers cleaner, more consistent outcomes.
- For builders, it unlocks a new substrate for private, composable coordination, and natively on-chain.
Built by Builders. Backed by Purpose.
Darklake and Arcium are more than aligned. We are builders with complementary strengths, united by a shared vision for the future of private, fair, and scalable markets. This is a partnership bringing together two best-in-class teams solving two sides of the same problem.
Together, we’re building you a new execution layer for DeFi.

🖥️ THE OBSERVATORY
A Machine. A Trail. A Warning.
You found it.
The hum of old circuits. The smell of scorched RAM and cheap takeout.
A terminal still running - untouched, but not abandoned.
I didn’t lock it. I left it open.
I’m Agent W.
Once a cog of the machine that enables the bleeding of wallets, now a MEV hunter that is preventing extraction.
I used to believe in the protocol. In fairness. In the idea that traders were safe, that transactions were airtight.
Then they took my stake.
2,187,433 SOL. Seized under a governance vote while I was offline.
They forgot who I am.
📂 What you’ll find
This isn’t your average website.
This is my journal. If you are here, it isn’t by accident. It’s because I wanted you to read it.
The devlogs I’ve developed, the blogs and whitepapers - all left behind to pass my learnings on to you and teach you how to shield yourself from the danger that lurks in the dark.
🔎 Why I’m doing this
Extraction cuts deep into someone’s finances. Take this report, for example:
🧾 March 2025
➜ 81.0 SOL traded
➜ 44.82 SOL extracted
That’s 55% of the total. It’s not a bit of risk - it’s more than half of what the trader had, now gone.

☠️ Final Warning
Once you start reading these blogs, you won’t see Solana the same way.
You’ll start noticing the shadows between blocks. The extractions that reach higher and higher amounts. The LPs getting less and less returns. The bots that never sleep. Front-runs disguised as fair trades. Mempools that are nothing but pens for cattle - corralling the cattle for the wolves to eat.
You’ll begin to understand that this isn’t a bug. It’s a battle in the name of fair markets.
The chain never forgets.
Neither do I.
Now, neither do you.
