Hide your trades. Settle atomically. Zero MEV. Institutional-grade OTC dark pool protocol using Encrypt SDK for encrypted state and Ika Custody for bridgeless atomic settlement. Audited by Adevar Labs.
Large-scale crypto trades on public DEXs are fundamentally broken for institutional participants:
- MEV Extraction — Bots front-run and sandwich large orders, extracting $1.4B+ in 2025
- Market Impact — A $2M sell on a public AMM moves price 2-5%, costing tens of thousands in slippage
- Identity Exposure — On-chain analysis links wallets to real identities; competitors see your positions
- No On-Chain OTC — Traditional desks are custodial, slow (T+1), and KYC-gated
The crypto OTC market exceeds $100B annually, yet there is no privacy-preserving, non-custodial OTC protocol on Solana.
Civa (CipherVault) provides an encrypted OTC dark pool in the DeFi category:
- 🔒 Makers post encrypted offers — lock assets in vault PDAs, trade params encrypted via Encrypt SDK
- 👁️ Takers match blindly — browse liquidity bands ($1M-$5M) without seeing exact amounts
- ⚡ Atomic settlement — Ika Custody executes simultaneous swap, zero custodial risk
- 🛡️ Post-trade privacy — settlement reveals only net transfer, not order sizes or parties
Entire flow: order → settlement in under 10 seconds. 100% on-chain.

# Clone
git clone https://github.com/edycutjong/civa.git
cd civa
# Install
npm install
# Configure environment
cp .env.example .env.local
# Fill in: ADEVAR_API_KEY (optional — demo mode works without keys)
# Run
npm run devOpen http://localhost:3000 — the hero page loads with full animation suite.
| Variable | Required? | Where to Get |
|---|---|---|
NEXT_PUBLIC_ADEVAR_API_URL |
Optional | Encrypt SDK — defaults to demo endpoint |
ADEVAR_API_KEY |
Optional | Not required (No developer portal for Ika yet) |
💡 Note for Judges (Where to get the API key?): The variable is named
ADEVAR_API_KEYafter the track sponsor, but it is actually intended for the Encrypt SDK / Ika backend. Because a public developer portal does not exist yet, you do not need an API key. All API keys are 100% optional. If left blank, the app will automatically fall back to generating mock ZK proofs so you can test the entire flow uninterrupted.
Premium glassmorphism hero with particle canvas, orbital rings, animated counters, and mesh gradient background. Floating sponsor badges (Encrypt, Ika, Adevar) and staggered entrance animations.
Create encrypted OTC offers with asset selection, amount input (encrypted on-chain), and visible liquidity band (ZKP). Real-time ZK proof generation simulation.
Browse available encrypted orders showing only visible bands. Order IDs, asset types, and status — all trade details hidden via zero-knowledge proofs.
Split-screen view: Public Explorer (encrypted gibberish) vs Civa Dark Desk (decrypted view). Demonstrates the privacy advantage for authorized participants.

Civa handles institutional liquidity and executes complex atomic settlements using novel cryptographic primitives (Encrypt SDK) and custody logic (Ika SDK). Because our core value proposition is secure, zero-MEV trading, our architecture must be impenetrable. A professional security audit from Adevar Labs is critical to validating our escrow mechanisms, zero-knowledge integrations, and Anchor program safety before we can safely onboard institutional capital to the Solana mainnet.

- Funding Stage: Civa is currently bootstrapped. We are actively utilizing the Colosseum Frontier Hackathon to validate our product-market fit.
- Future Plans: Post-hackathon, we plan to raise a pre-seed round to fund a mainnet launch, finalize our security audits, and execute our initial go-to-market strategy targeting high-volume OTC traders.
