BLOCKCHAIN

Confidentiality for on-chain applications

On a public blockchain, the transparency that's supposed to protect you works against you. Arcium adds encrypted shared state to every application that needs it.

USE CASES

Built for confidential blockchain

Encrypted execution unlocks the applications public chains could never support. Here is what becomes possible.

01 DeFi & Trading

Private DeFi and Trading

The problem

Every order you place is visible before it executes. Every position you hold is visible to the world. On a public blockchain, the transparency that's supposed to protect you is the thing working against you.

How Arcium solves it

Your trade logic executes in a fully confidential state. The transaction is submitted, settled, and finalized without exposing any information about the trade. No one sees your intent. No one reads your position. The chain validates the result without ever seeing the inputs.

What this enables

Trade, swap, lend, and borrow without exposing your transactions. Build dark pools, encrypted perps, and new prediction markets with encrypted execution, so on-chain trading can finally meet mainstream standards.

DARK POOLS, ENCRYPTED PERPS
02 Payments

Confidential Payments

The problem

Every time you send a payment on-chain, the recipient can see your entire wallet. Your balance, your history, every transaction you've ever made. Privacy coins help for a single asset, but they don't extend to general computation or cross-ecosystem activity.

How Arcium solves it

Payments execute with confidential amounts and confidential balances. The transaction settles on-chain and stays verifiable, but wallet balances stay encrypted and transaction amounts stay confidential.

What this enables

Build payment applications where users have financial confidentiality by default. Send and receive value without revealing balances or history. Implement confidentiality for any token, program, or app on Solana with C-SPL.

03 Gaming

Onchain Gaming and Hidden Information Games

The problem

Poker doesn't work if everyone can see everyone's cards. Neither does any game where secrets matter. On a public blockchain, all state is readable, so any player can scan the chain and act on what should be hidden. The only workaround today is moving game logic off-chain, which defeats the point.

How Arcium solves it

Game logic runs encrypted on-chain. Players can't see each other's hands, read hidden state, or predict outcomes by scanning the blockchain. Information reveals only when your game logic says it should, on card flip, on turn completion, on match end.

What this enables

Poker with hands that stay hidden until showdown. Strategy games where fog of war actually works on-chain. Any application where information asymmetry matters. If your game needs secrets, you can build it now.

HIDDEN STATE, FOG OF WAR
THE UNLOCK

Not all confidentiality is created equal

Three generations of on-chain state. Arcium delivers the third, the one the entire industry has been missing.

01 First Generation

Public Shared State

The original blockchain model. All participants write to and read from one unified ledger, powerful for coordination, but nothing is private.

  • All data is permanently visible to everyone on-chain
  • Impossible to build apps needing sensitive inputs
  • Front-running and MEV are structurally unavoidable
  • Enterprise and regulated use cases are blocked
02 Second Generation

Isolated Encrypted State

Zero-knowledge proofs brought individual encryption, each user can keep their own data secret. A major step, but state stays siloed per user.

  • Individual data stays encrypted from observers
  • No shared encrypted state across parties
  • No composability between encrypted apps
  • Blocks collaborative use cases
03 The Holy Grail

Encrypted Shared State

Multiple parties compute over the same encrypted data simultaneously, without any party ever seeing the underlying values.

  • Individual data stays encrypted from observers
  • Shared encrypted state across multiple parties
  • Composable, encrypted apps interoperate
  • Confidential DeFi, shared AI, multi-party auctions

Arcium powers leading blockchain teams

Confidential compute, running in production across the Solana ecosystem.

Arcium enables a new wave of 0-to-1 applications. Sealed-bid auctions, the gold standard in TradFi, were never possible on-chain. With Arcium, we calculate a uniform clearing price on fully encrypted bids, with an interface as simple as writing an Anchor program.
