SEALED-BID BATCH AUCTIONS FOR DIGITAL ASSETS

By the time the lot is announced, the price has already moved.

Large digital-asset sales leak. Wallets are watched and transfers are reported as they happen — the market prices the disposal before the first bid is placed. Datum gives auction houses a sealed-bid mechanism with escrowed settlement that keeps the sale confidential until it clears.

CONFIDENTIAL UNTIL CLEARING
ONE PRICE FOR ALL FILLS
FULL AUDIT TRAIL FOR THE AGENCY
Non-custodial — Datum never holds the asset or the cash.

01 — THE PROBLEM

Three ways to sell a large lot. Each one costs the seller.

Move it to an exchange.

Every transfer is public. When Saxony sold 49,858 BTC in 2024, on-chain trackers reported each tranche to exchanges and market makers as it moved — a €2.6 billion sale, visible to the entire market while it was still underway.

Split it into small lots.

When seized coins have gone to public auction, houses sold them in small retail lots. Retail absorbs those; it does not absorb institutional size, and weeks of small sales means weeks of price risk.

Negotiate privately.

Fast and quiet, but the price answers to nothing. The agency is asked to take it on faith that the discount was fair.

Each route gives up confidentiality, size, or price discovery. A sealed-bid auction gives up none.

02 — THE MECHANISM

Sealed bids. One window. One price.

1 · ESCROW

The lot locks in on-chain escrow at auction open. Datum never holds it.

2 · SUBMISSION

Bidders place funded limit orders during a fixed window. No order book is published. Arrival time confers no advantage.

3 · CLEARING

At close, a single price maximizes matched volume. Every fill executes at that price. Below the seller's confidential reserve, nothing trades and nothing is disclosed.

4 · SETTLEMENT

Delivery versus payment through escrow. The asset releases only against confirmed payment.

WHY ONE PRICE.

A single clearing price reduces the incentive to shade bids and the winner's curse that deters bidders in pay-as-bid formats. It is the mechanism behind equity closing auctions — which set roughly one in ten shares traded on Nasdaq each day — and behind US Treasury auctions, which moved to uniform pricing in 1998 for the same conditions: concentrated size and informed bidders.

03 — DISCLOSURE

Confidential to the market. Transparent to the mandate.

05 — WHAT COMES NEXT

Seized assets are the first lot type, not the last.

Tokenized funds are entering institutional portfolios. Rebalancing at size needs scheduled, confidential price formation — the role closing auctions play in equities today. The house that builds its record on seized assets is the house those mandates come to next.

Built for the firms that already do this work.

We are looking to run a pilot with a US auction house active in government and law-enforcement disposals, on a single lot. No change to your mandate. No change to how you invoice. The briefing is thirty minutes: the mechanism, the disclosure model, and a pilot outline.
