what's Undesk?

Undesk is a private over-the-counter (OTC) trading platform built on Solana, enabling encrypted peer-to-peer trading for large trades with complete privacy. It eliminates slippage, front-running, and information leakage by using Arcium's multi-party computation (MPC) network for end-to-end encryption of deals, offers, and balances—no single party, including operators, can access details. Fully non-custodial, funds are escrowed in private shared pools on-chain, always retrievable by users. The protocol features blind matching: deal creators post encrypted trade details (assets, size, price) and deposit collateral; offerors submit blind offers without seeing specifics, with invalid ones rejected privately. Settlement executes via encrypted MPC on-chain, ensuring matched parties get desired prices or better. It supports any SPL token via mint address, uses deterministic private addresses for security, and plans RFQ enhancements. Currently on devnet.[[3]](https://www.undesk.trade/)
