The results for Arcium’s Encrypted Sidetrack on Superteam Earn are in — and after reviewing 129 submissions (yes, one hundred and twenty-nine), we’re excited to highlight the teams that delivered the strongest encrypted apps and made the most of Arcium’s MPC stack.
Below are the five winners, followed by a selection of honorable mentions whose work also stood out.
Pythia is a private opportunity market where people bet on startups they have real conviction about and VCs pay for that signal, powered by Arcium’s encrypted compute that keeps the sponsor-only price window private. The private window preserves alpha by letting only sponsors see price action, while the later public window gives broader traders more information to refine the market.

A closed-loop “unstable coin” where every transfer randomly mints or burns supply, creating individual wins, socialized wins/losses, and an encrypted peg powered by Arcium’s confidential compute.
View submission →
A dark pool that keeps orders encrypted end-to-end. Trade without front-running and quote fading for the best execution price.
View submission →
A dark-pool style on-chain orderbook where every order is encrypted and matching happens privately inside Arcium. No front-running. No alpha leaks.
View submission →
A privacy-first social travel network. Users discover travel partners through encrypted compatibility scores without revealing dates, routes, or interests.

Although they did not place in the top five, we also want to recognize the strong work from the following teams (listed in no particular order):
Stealf: A stablecoin neobank using Arcium for private transactions, built on a dual-wallet model: a public wallet and a private wallet.
Anonmesh: A privacy-oriented messaging and payments app, using Bluetooth (BLE) for direct, peer-to-peer communication.
Subly: Subscribe Now, Pay Never. The privacy-first PayFi protocol for subscription services.
ArxPredict: A confidential prediction market where all LMSR pricing and vote aggregation are computed privately.
The Casino & The Church: A dual-realm crypto game featuring multiple provably-fair casino games, each powered by Arcium’s CSPRNG.
SolRouter: A private AI platform that uses Arcium for client-side encryption, with TEEs used to re-encrypt model outputs before returning them to the user.
Unchain Protocol: A private, censorship-resistant tipping protocol for the creator economy.
Fungerbil: A cross-chain privacy protocol enabling Monero-to-Solana DeFi with encrypted infrastructure.
ClimeMate by thecorgod: A privacy-preserving system for measuring, verifying, and reporting greenhouse gas emissions on Solana.
CipherScore: A privacy-first credit scoring service that lets you verify your financial data without ever revealing it.
These builders all showed strong intuition for encrypted design and compelling early use-cases for Arcium.
Every submission — winner or not — strengthens the momentum we’re seeing across the ecosystem. Developers are beginning to explore what becomes possible when logic and data can be computed in encrypted form, and at scale.
We’re proud of the work these teams shipped, and we look forward to supporting their continued development.
We’re also closing the Sidetrack with the release of Arcium v0.4.0, which went live last week. This update includes Ed25519 support, CLI profiling, performance optimizations across Arcis and Arx nodes, compatibility with Anchor v0.32.1, SHA-3 hashing, automatic key syncing, and improved CLI error messaging. Developers can follow this post for full details and the migration guide here.
