Why OptiVaults?

A smarter way to earn yield on your stablecoins without the complexity of manual DeFi farming.

Non-Custodial

Your funds are held by on-chain smart contracts, not by us. Withdraw anytime with your wallet — no permission needed.

Auto-Compounding

Yields are harvested and reinvested automatically. Your share value grows over time without any manual action.

On-Chain Security

13 immutable fields, exact-value validation, and role separation. All critical operations enforced by Aiken PlutusV3 validators.

Optimized Allocation

A risk-aware strategy engine allocates across multiple DeFi protocols to maximize risk-adjusted returns.

Mobile-First

Works with any CIP-30 wallet — Vespr, Eternl, Nami, Lace. Server-side TX building means no WASM on your device.

Open Source

Smart contracts are open source under BSL 1.1. Verify the code, audit the logic, trust the math.

How It Works

Three simple steps to start earning yield on your stablecoins.

1

Deposit

Connect your Cardano wallet and deposit stablecoins into the vault. You receive vUSDCx share tokens representing your proportional claim.

2

Earn

The automated keeper deploys capital across DeFi protocols, compounds yields, and rebalances — all validated on-chain.

3

Withdraw

Burn your vUSDCx shares anytime to receive your original deposit plus accumulated yield. No lock-ups, no permission required.

Security First

Built from day one with security as the top priority. Every operation validated on-chain.

13 Immutable Fields

Admin keys, fees, and policies are locked at deployment. No operation can alter them.

Exact-Value Validation

Deposit and compound outputs are validated with exact equality — no room for value extraction.

Role Separation

Admin, Keeper, and User roles have distinct keys and capabilities. No single key controls everything.

Flash Loan Resistant

Direct withdrawals always charge a fee. Batched withdrawals require queuing. Both prevent same-block exploits.

Inflation Attack Protection

Share multiplier and minimum deposit work together to block ERC-4626 style inflation attacks.

Slippage Protection

Token-specific minimum receive amounts enforced on-chain. Users are protected against sandwich attacks.

9 Audit Rounds

80+ security fixes applied across contracts, API, frontend, and keeper. 554 automated tests.

Open Source Contracts

Smart contract code is publicly available for independent verification and community auditing.

Roadmap

From smart contract development to a fully decentralized yield protocol.

Phase 1 — Smart Contracts
Aiken PlutusV3 vault with 11 redeemers, 272 on-chain tests, 9 audit rounds
Phase 2 — Keeper Infrastructure
Automated compound, rebalance, batch processing, risk engine, multi-protocol integration
Phase 3 — Frontend & API
React SPA with CIP-30 wallet support, server-side TX building, JWT auth, real-time WebSocket updates
Phase 4 — Preprod Verification
Two rounds of on-chain E2E testing, 13 confirmed transactions, all redeemers verified
Phase 5 — Mainnet Launch
Contract deployment, professional audit, public beta, community testing
Phase 6 — Multi-Vault & Governance
Multiple vault instances with different risk profiles, governance token for decentralized parameter management
Phase 7 — Cross-Protocol Expansion
Additional DeFi protocol integrations, formal verification of key contract properties
