Examples - Arcium Docs

Browse complete MXE projects in the Arcium examples repository. Each project includes its Arcis circuits, Solana program, tests, and setup instructions.

The examples currently target Arcium 0.13.2, while the latest toolchain is 0.15.0. Check each project’s manifests before copying code into a project on another release.

Start with the fundamentals

Example	What it demonstrates	Maps to
Coinflip	Trustless randomness with `ArcisRNG`; stateless circuit	Arcis primitives, Callback type generation
Rock Paper Scissors: player vs player, player vs house	Encrypted async gameplay with hidden moves or an MPC-generated opponent	Input/output, Callback accounts, Arcis primitives

Build stateful applications

Example	What it demonstrates	Maps to
Voting	Private ballots with public results via encrypted state accumulation	Callback type generation
Share medical records	Patient-controlled re-encryption between parties	Sealing
Sealed-bid auction	Encrypted bid comparison supporting first-price and Vickrey mechanisms	Operations

Explore advanced patterns

Example	What it demonstrates	Maps to
Blackjack	Hidden deck state with `Pack<T>` for compact encrypted storage	Arcis primitives, Types
Ed25519 signatures	Threshold signing where the private key never exists in one place	Arcis primitives, Input/output
