The institutional execution venue crypto has been missing. Trade $10M+ on Solana without your position being visible, exploited, or front-run: cryptographically private orders, peer-to-peer matching, 400ms settlement.
$3.5B+
MEV extracted from Solana traders, 2020–2025
$30M
Drained from one strategy by a single bot, in 2 months
Every large trade is a public announcement until now.
The moment a large order hits Solana's public flow, every MEV bot knows your size, direction, and price before a single token moves. TradFi solved this 30 years ago. Crypto had no equivalent.
01.
Cryptographic Security
Your order is split into secret shares across Arx nodes before it leaves your device. No single node can read it.
02.
Zero MEV Exposure
Front-running requires seeing your order first. PriMesh makes that structurally impossible.
03.
Atomic Settlement
Both sides deliver in a single Solana transaction, or neither does. Funds never leave your wallet until the moment of settlement.
04.
Advanced Order Types
TWAP, VWAP, Limit. The full institutional execution toolkit, rebuilt on encrypted infrastructure.

Cryptography keeps every order sealed.
Secured by math, not by promises. Your funds stay in your wallet, with no vault, no pooled custody, and nothing to drain. Orders encrypt before submission and match where no node sees them in plaintext.

A $10M sell, two receipts.
Same order, same market. Ranges reflect typical mid-cap Solana conditions.
01.On a public DEX
You receive
$9.0M – $9.6M
Lost $400k – $1M to extraction and slippage.
How it happens
01Order broadcast to the public mempool, where every searcher sees size, side, and price.
02Front-runners and sandwichers extract $80k – $400k before the fill.
03Fill splits across 8–15 pools, with 4–10% effective slippage between hops.
04Settles in 30 – 60 seconds after routing.
02.On PriMesh
You receive
$9.995M – $9.999M
Paid $500 – $5k in execution cost. No extraction.
How it happens
01Order encrypted on your device and Shamir-split across MPC nodes, so no plaintext exists.
02Nothing broadcast and nothing to front-run, so MEV loss is $0.
03Peer-to-peer match at 0.5 – 5 bps. No pool routing, no market impact.
04Both legs land in a single 400ms atomic Solana transaction, or neither does.
$400k – $1Mrecovered per $10M trade.
