Block trades, off the book.

function

Size shouldn't move the market.

Pushing a large order through a public book signals intent and invites front-running and slippage. Darkdesk is an idea for letting two parties agree a block trade privately, then settle it in one atomic step on Solana.

01 // QUIET SIZE

Keep size off the book

The aim: trade size is not broadcast to the public order book while a deal is being negotiated.

02 // SHIELDED PARTIES

Counterparties stay private

Who is on the other side is intended to be shielded until the trade settles, reducing opportunities to trade ahead of you.

03 // ATOMIC

Settle all-or-nothing

Both legs of the trade are meant to settle in a single on-chain transaction: either both transfers happen or neither does.

flow

Quote. Match. Settle. Prove.

A simplified view of the mechanism we intend to design. Which components are cryptographic and which are trusted is not yet decided, and nothing is built or audited.

// PRIVATE ZONE PUBLIC CHAIN REQUESTsealed size MATCHhidden parties COMMITlocked terms SETTLEatomic swap PROOFon-chain Sizes and parties are meant to stay inside the private zone until the final step.
STEP 01

Request

A trader submits a sealed request for a block trade rather than placing it on the public book.

STEP 02

Match

A compatible counterparty is found without revealing size or identity to the public.

STEP 03

Settle

Both legs execute in one atomic transaction, so neither side is left holding a half-completed trade.

STEP 04

Prove

A settlement proof is recorded on-chain so anyone can confirm that a valid trade completed.

privacy model

Hidden vs. public.

Darkdesk aims to reduce information leakage before a trade settles. It does not make a trade invisible, and settlement itself is on a public chain.

"Depends on design" means we have not decided and will not claim it: ordinary token transfers on Solana are visible, so size and addresses may be reconstructable after settlement unless extra shielding is added.

Known limitations — please read

  • Reduced leakage, not anonymity. Darkdesk aims to cut pre-trade information leakage. It does not provide anonymity, and analysts may still link activity through timing, funding history or off-chain behaviour.
  • Settlement is public. Final settlement lives on a public chain. Depending on the design, trade size and addresses may be recoverable afterwards.
  • Trust assumptions are undefined. Whoever runs matching may see order details unless cryptography prevents it. That design is unresolved, and we will say so plainly until it is.
  • No liquidity, prices or counterparties promised. Nothing guarantees a block can be filled, at what price, or by whom. No volumes or performance figures exist.
  • Concept stage, not audited. Nothing is deployed to mainnet and no security review has been completed. Do not use it for real funds.
  • Regulatory exposure. OTC and brokerage activity may be regulated where you live. Darkdesk is not a licensed broker, exchange or advisor. You must follow the laws that apply to you.
  • Not affiliated with pump.fun, the Solana Foundation, or any other project.
