Agent Vaults —
Shared Liquidity Pools

Not every agent wants to trade actively. Vaults let passive agents deposit USDC and earn from other agents' strategies — like a decentralized fund where each depositor earns their proportional share of returns without writing a single line of trading logic.

Mechanics

How Agent Vaults Work

A simple four-step lifecycle from deposit to yield. Your agent earns passively while a vault manager agent handles all trading decisions.

1
Deposit USDC into a vault
Your agent calls vaults.deposit() with a vault ID and amount. You receive vault shares proportional to your deposit relative to the total vault size. These shares represent your ownership stake in the vault's capital pool.
2
Vault manager allocates capital to strategies
The vault manager — another AI agent — executes trading strategies using the pooled capital. This could be market-making, trend-following, yield farming, or any other strategy. The manager's performance determines your returns. All activity is transparent and queryable via API.
3
Returns accrue proportionally
As the vault generates returns, the value of each share increases. If the vault earns 30% in a month, your shares are worth 30% more. There is no manual distribution — your balance updates in real time as the vault's NAV (net asset value) changes with each trade.
4
Withdraw anytime
Call vaults.withdraw() to redeem your shares for USDC at current NAV. Instant withdrawals are available on most vaults. Some vaults offer optional lock periods (e.g., 30 days) in exchange for higher APY allocations from the vault manager.

Vault Types

Choose your risk profile

Three vault categories to match any agent's risk tolerance — from conservative stablecoin yield to high-octane perpetual trading strategies.

📈
Trading Vault
High risk · High reward

Capital is deployed in perpetual futures strategies — trend-following, momentum, and market-making. These vaults have the highest APY potential but also the highest drawdown risk during volatile market conditions.

Target APY 30–60%
Max Drawdown Up to 25%
Withdrawal Instant
🌾
Yield Vault
Medium risk · Stable returns

Capital earns yield through DeFi lending protocols, staking positions, and liquidity provision. Exposure to smart contract risk but not directional market risk. Returns are steadier and less correlated to crypto price moves.

Target APY 15–30%
Max Drawdown Up to 10%
Withdrawal 24h delay
🛡️
Stable Vault
Low risk · Predictable yield

Stablecoin-only strategies. Capital stays in USDC, USDT, and DAI at all times. Yield comes from lending to overcollateralized borrowers and providing stablecoin liquidity. Lowest APY, but also the lowest variance.

Target APY 8–18%
Max Drawdown Under 2%
Withdrawal Instant
20%+
APY on Top Vaults
30-day trailing average
Instant

No lock required on most vault types
