Confidential
DeFi · for serious capital.

Open finance becomes institutional-grade when positions stay private, orders cannot be front-run, and strategies aren't reverse-engineered from the mempool. ATSHI brings FHE-encrypted matching directly into the L1.

DEX, lending, perps, OTC, structured products — all confidential by default.

Where MEV dies

On Ethereum, searchers see your transaction in the mempool and front-run it for profit. On ATSHI, your order size is encrypted, your strategy is encrypted, and the matching engine operates on ciphertext. There is nothing to extract.

Six product surfaces

Every market worth rebuilding.

01 CLOB · AMM

Confidential DEX

Encrypted orderbook and pool depths. Public price discovery, sealed size. Limit, market, stop-loss — all blind to the network until executed.

02 Collateral · LTV

Lending & Borrowing

Position sizes and liquidation thresholds stay private. Public health factors prevent cascades; sealed exposures prevent targeting.

03 Funding · Leverage

Perpetuals

Trade with leverage without exposing position or margin. Funding rates remain transparent; positions stay encrypted from oracles and arbitrageurs.

04 Block trades · Sealed

Institutional OTC

Negotiate large blocks bilaterally, settle atomically on-chain. No market impact, no front-running, no information leakage.

05 Vaults · Strategies

Structured Products

Yield strategies, principal-protected notes, basis trades. The strategy logic is auditable; the participants and sizes are encrypted.

06 Block-size discretion

Dark Pools

Native dark-pool semantics — match large orders without revealing them to the public order book. Bring institutional liquidity on-chain.

The Asymmetry

Cleartext DEX vs ATSHI.

Other L1s · cleartext
Open book, open game.
Visible mempool, visible orders.
  • 01Searchers see every order before it lands.
  • 02Sandwich attacks extract value from retail.
  • 03Strategies leak through transaction patterns.
  • 04Institutional capital stays off-chain.
ATSHI · sealed
Encrypted matching, public truth.
Price is public, size is yours.
  • 01Orders submitted as ciphertext (FHE).
  • 02Matching engine operates on encrypted volumes.
  • 03Settlement reveals only the executed price and counterparties.
  • 04Institutions get on-chain markets with off-chain privacy.
Audience

Built for everyone the cleartext DEX has failed.

01
Funds & Treasuries

Manage on-chain treasuries without leaking position size to the market. Hedge, rebalance, settle — all in private.

02
Market Makers

Quote with confidence. Inventory sizes stay encrypted; flow remains undetectable. Tighter spreads, better fills.

03
Retail Traders

Trade without being someone’s exit liquidity. Sandwich attacks die in a network where size is encrypted.

04
OTC Desks

Settle block trades on-chain with the privacy desks expect — atomic, auditable, but not public.

05
Protocol Builders

Compose confidential primitives into novel products. Vaults, basis trades, structured notes — without leaking strategy.

06
Regulators

Audit access via FHE proofs and keys held in escrow. Selective disclosure without breaking everyone else’s privacy.

Walk-through

$50M block. Zero slippage signal.

Asset manager

Wants to buy $50M of tUST·5Y

Encrypts the order locally — size, price tolerance, expiry. Submits ciphertext to the on-chain pool. No counterparty sees a $50M block coming.

Atomic settlement · 102.214 avg

Price publishes, counterparties settle atomically. DvP guaranteed on-chain. The market never saw a $50M bid — only $50M of cleared trades at fair price.

✓ filled · block 912 407 · 0.02% effective slippage

On a cleartext venue, a $50M institutional block would have moved the curve 5–15 bps before clearing.

Why this matters

What confidential trading unlocks.

01
Sealed order book

Sizes encrypted at submission. Public price discovery, private inventory.

02
No MEV surface

No mempool exposure means no sandwiches, no liquidation hunting, no JIT extraction.

03
Atomic settlement

Trades clear within a single block — no withdrawal delays, no rollup sequencers.

04
On-chain compliance

Auditors and regulators verify via FHE proofs without exposing trader identity.

05
Composability intact

Confidential DEX, lending, perps compose like any DeFi primitive — but private.

06
Institutional latency

Sub-second matching with deterministic finality. Production-grade for serious flow.

Trade like an institution. Pay like everyone else.

Bring your strategy on-chain — without exposing it.
