Five things no wallet
has ever done.

Each feature solves a real DeFi pain point. Not in a roadmap — built into the core from day one.

👻
WORLD FIRST
Intent-Based Ghost Routing

Set a swap intent with outcome conditions — price, gas, slippage — and NexVault's background agent executes automatically when all conditions are simultaneously optimal. You never need to time the market again.

How it works: Sign an off-chain intent → agent monitors mempool, liquidity, gas across all DEXes → executes on-chain via GhostSettlement.sol when all 3 conditions align atomically.
🔐
WORLD FIRST
ZK-Receipt Privacy Attestation

After every swap, generate a zero-knowledge proof that you executed a valid trade — without revealing your wallet address, amounts, or counterparty. Prove DeFi activity to lenders or auditors without doxxing yourself.

Tech: snarkjs + Groth16 circuit · nullifier-based replay prevention · exportable as QR-encoded proof · on-chain verifiable via ZKReceiptVerifier.sol
🧬
WORLD FIRST
Wallet DNA Biometric Guard

Your private key is cryptographically bound to your biometric on your specific device. Even if your seed phrase is stolen, funds cannot be moved without your Face ID or fingerprint on the enrolled device.

Derivation: Seed entropy + Secure Enclave ECDH key agreement → HKDF → final key. CryptoKit on iOS · Android Keystore BiometricPrompt. Fully documented in security whitepaper.
🛡️
WORLD FIRST
Social Recovery with Time-Lock

Nominate 1–5 on-chain guardians. Recovery uses Shamir's Secret Sharing — a configurable threshold must submit shards. A 48-hour time-lock gives you time to cancel if triggered without your consent.

Guarantee: No centralized server ever sees a shard · end-to-end encrypted guardian comms · original owner can always cancel within 48h window · on-chain via RecoveryGuard.sol
WORLD FIRST
Micro-Portfolio Autopilot — DeFi Cron Jobs

Create on-chain automated DeFi strategies you actually own. Non-custodial cron jobs powered by Chainlink Automation and ERC-4337. Auto-compound rewards, rebalance portfolio, auto-stake idle tokens. No third-party bot ever holds your keys.

Examples: "Auto-compound Aave USDC rewards every 24h" · "Rebalance to 60% ETH / 40% USDC every Sunday" · "Auto-stake idle MATIC when balance exceeds 50 MATIC" — all non-custodial, all on-chain, user-signed UserOps only.
DEX Aggregation

Best price.
Every trade.

NexVault fans out to 6 DEX providers simultaneously and picks the optimal route — or splits across multiple pools when that beats any single route.

🔀
Split Route Optimization
When splitting across pools beats any single route, NexVault splits automatically — no manual configuration needed.
🛡️
MEV Protection
Routes through Flashbots Protect private mempool by default. Your trades don't appear in the public mempool until mined.
Gasless Limit Orders
Sign a limit order off-chain. Pay zero gas upfront. Executors fill your order when the price is hit — you only pay when you win.

Security Architecture

Built for paranoid people.
That's a compliment.

Every security decision was made before the first line of code. No retrofits. No compromises.

🔑
2-of-3 MPC Key Splitting
Your private key is split into 3 shards using threshold cryptography the moment it's derived. It is never stored whole — not in memory for more than a single signing operation.
noble-curves noble-hashes AES-256-GCM
📱
Secure Enclave Signing
On mobile, all signing operations happen inside iOS Secure Enclave or Android StrongBox TEE. Key material never touches the application layer.
CryptoKit Keystore BiometricPrompt
🌐
WebCrypto Non-Extractable Keys
In the browser, private key material is stored only as non-extractable WebCrypto CryptoKey objects. No private key ever touches localStorage, sessionStorage, or any extractable form.
WebCrypto API IndexedDB Dexie.js
Panic Freeze
One tap locks your wallet and blocks all outgoing transactions at the smart contract level — not just in the app. Even if your phone is compromised, no funds can leave while frozen.
On-chain ERC-4337 Instant
🔮
Transaction Simulation
Every transaction is simulated via Tenderly before you confirm it. You see the exact state changes — tokens in, tokens out, approvals granted — before signing anything.

Audited Contracts
All 6 smart contracts are audited by Trail of Bits, ConsenSys Diligence, and OpenZeppelin before mainnet. 100% Foundry test coverage. Slither zero HIGH/MEDIUM policy.
