AI-Managed Vault
The AI-Managed Vault is a fully functional, on-chain capital management system deployed on Base.
It combines the ERC-4626 tokenized vault standard with multi-strategy allocation, autonomous keeper-based rebalancing, and a comprehensive fee and safety system.
Architecture
The vault implements ERC-4626. Users deposit USDC and receive vault shares proportional to their deposit. The vault manages assets across multiple DeFi strategies through dedicated adapter contracts.
Vault Contract: 0x3E6bf646b379C75d47Cf91d5569621FD0df53d78 (Base Sepolia)
Underlying Asset: USDC (0x25b56942824E65B5d83BD57f54e3518CccFcd088 — MockUSDC on testnet)
The total assets under management equals idle USDC in the vault plus the sum of assets deployed across all registered strategy adapters.
Strategy Adapters
The vault allocates capital through four dedicated adapter contracts:
Aave Adapter — deposits into Aave lending pools
Compound Adapter — deposits into Compound lending markets
Uniswap V3 Adapter — concentrated liquidity positions
Aerodrome Adapter — liquidity provision and gauge staking
Each adapter implements the IStrategyAdapter interface, providing standardized deposit(), withdraw(), and totalAssets() functions. New strategies can be added through the addStrategy() function with a configurable maximum exposure limit.
Keeper System
The keeper is a dedicated wallet authorized to execute rebalances on the vault contract. The onlyKeeper modifier restricts the rebalance() function to this address or the contract owner.
Rebalancing accepts an array of strategy addresses and target weights in basis points (summing to 10,000). The vault redistributes capital across strategies accordingly. The keeper can also trigger harvestAll() to collect rewards from all active strategies.
Fee Structure
The vault collects fees through four mechanisms:
Management Fee — annual fee in basis points, accrued over time (maximum 5%)
Performance Fee — charged on profits above the high watermark (maximum 30%)
Deposit Fee — entry fee deducted from deposits
Withdrawal Fee — exit fee deducted from withdrawals
Fees are collected to a designated treasury address. The high watermark ensures performance fees only apply to new profits — during recovery periods after a drawdown, no performance fees are charged.
Safety Mechanisms
The vault includes multiple layers of protection:
Pausable — emergency pause halts all deposits, withdrawals, and rebalances instantly
ReentrancyGuard — prevents reentrancy attacks on deposit and withdrawal functions
Ownable2Step — two-step ownership transfer prevents accidental or malicious ownership changes
Max Drawdown Halt — if vault value drops below the drawdown threshold (configurable, default 15%) relative to the initial share price, operations halt automatically
High Watermark — tracks peak share price, preventing performance fee extraction during recovery
Mandate Enforcement
The off-chain allocation engine enforces all mandate constraints before submitting any rebalance transaction to the keeper. The keeper will not submit a transaction that violates the mandate.
The on-chain contract provides an additional safety layer through the pause mechanism and drawdown check, creating defense in depth.
Current Deployment
The vault is live on Base Sepolia testnet. All strategy adapters are deployed and registered. The keeper wallet is funded and operational. Mainnet deployment is planned following further testing and audit.
