What's New in v5.2 — Sovereign Infrastructure

Plan v5.2 "Sovereign Infrastructure" delivers privacy contracts, multi-vault routing, proof of solvency, autonomous AI memory, and sybil-resistant governance across the Vauban ecosystem.

Bastion (DeFi Platform)

VaultRouter — Multi-Vault Deposits

Deposit into the optimal vault with a single transaction. VaultRouter analyzes APY, capacity, and risk across all active vaults and routes your deposit for maximum yield.

• Optimal vault selection: On-chain routing logic picks the best vault based on current APY and capacity
• Multi-vault deposits: Split a single deposit across multiple vaults for diversification
• Auto-approve: Router handles token approvals internally — one transaction, not three

User deposits 1000 STRK
  → VaultRouter checks vaSTRK vault (12% APY, 80% capacity)
  → VaultRouter checks vawBTC vault (8% APY, 40% capacity)
  → Routes to vaSTRK (best risk-adjusted yield)
  → User receives vaSTRK LST tokens

Portfolio Dashboard

Track your entire DeFi position in one view:

• Allocation breakdown: See how your assets are distributed across vaults and protocols
• Live APY comparison: Vauban vaults vs Ekubo, Nostra, Vesu — updated every 5 minutes
• Yield projection: Forecast earnings at current rates over 30/90/365 days
• Rebalancer alerts: Get notified when APY drift exceeds your threshold

Multi-Vault Rebalancer

Automated APY drift monitoring with configurable thresholds:

• Monitors all vault APYs every 30 minutes
• Triggers rebalance suggestions when drift exceeds threshold (default: 2%)
• Strategy templates: Conservative (stable vaults), Moderate (mixed), Aggressive (highest APY)

VaubanSwap (CoW Solver)

Starknet's only Coincidence of Wants solver for MEV-protected swaps:

• Batch settlement: Opposing intents matched off-chain, settled on-chain via VaubanSettlement
• Surplus capture: When CoW matching finds better prices than market, surplus goes to users
• AVNU fallback: Unmatched intents automatically routed through AVNU aggregator
• Zero MEV: No front-running possible — intents are signed off-chain with SNIP-12

Proof of Solvency

On-chain proof that Vauban reserves always exceed liabilities:

• Phase 1 (Live): Merkle root anchoring on Madara L3 via ProofRegistry contract
• Phase 2 (Planned): Full STARK proof via Stwo prover — cryptographically verify without revealing balances
• Weekly attestations: Automated data aggregation + proof anchoring every 7 days
• Public verification: Anyone can verify proof hashes on-chain

Yield DCA (YieldIntentVault)

Idle DCA funds earn yield while waiting for execution:

• Deposits into Nostra lending pools during idle periods
• 10% liquid buffer maintained for reliable execution
• Auto-unstake when execution triggers
• Per-user cap: 100K STRK, minimum stake: 10 STRK

Glacis Protocol (Post-Quantum Identity)

DaoGovernance — Sybil-Resistant DAO

One person = one vote governance using HumanAttestation SBTs:

• Sybil resistance: Voting power tied to attestation, not token holdings
• Quorum snapshotted per proposal: Prevents quorum manipulation attacks
• Voting delay > 0: Mandatory delay prevents flash-loan governance attacks
• Parameter update events: All governance parameter changes emit events for transparency

TimelockController

Time-delayed execution for critical operations:

• Proposer/Executor roles: Separation of proposal and execution privileges
• Configurable delay: Minimum waiting period before execution (default: 24 hours)
• Cancellation: Proposers can cancel pending operations
• Batch operations: Execute multiple calls in a single timelocked transaction

Privacy Contracts

StealthRegistry (ERC-5564)

Stealth addresses for private transactions:

• Stealth meta-addresses: Register once, receive at unlimited stealth addresses
• Ephemeral keys: Each transaction uses a unique derived address
• 20/20 tests: Comprehensive test coverage including edge cases

ConfidentialPool (Privacy Pools v1)

Pseudonymous transactions with Poseidon commitments:

• Deposit/withdraw with commitments: Poseidon hash commitments + nullifiers
• Reentrancy-protected: Guard on all state-changing functions
• felt252 bounds checking: Overflow protection on all arithmetic
• 29/29 tests: Full coverage including audit-hardened edge cases

Security Audit Results

v5.2 underwent a comprehensive 10-epoch security audit:

All CRITICAL and HIGH issues resolved. See the full audit report in the Brain knowledge base.
