USDC Vault
Overview
The AQUA USDC Vault is an ERC-4626-based stablecoin yield vault built on AQUA Market.
Users deposit USDC, receive aqUSDC Vault shares, and gain exposure to market-based yield generated through approved strategies without having to manage individual lending or liquidity positions directly.
The Vault accepts only USDC as its designated deposit asset and operates under configured strategy limits, liquidity parameters, risk controls, and reporting requirements.
Purpose
The USDC Vault is designed for users and institutions seeking USDC-denominated yield within the AQUA ecosystem.
Deposited USDC may be allocated across approved strategies, which may include:
AQUA lending markets
Approved external stablecoin lending markets
Approved fixed-rate or fixed-term strategies
Other disclosed USDC-denominated yield strategies
The Vault is intended to support liquidity across AQUA Market while providing depositors with a single, transparent Vault position representing their proportional interest in the Vault’s recognized assets.
Strategy availability, allocation limits, and applicable risks may vary over time.

Target APY: TBD
Instant / T+1 Queue
The USDC Vault accepts only USDC through the supported deposit process.
Tokens transferred directly to the Vault contract outside the official deposit flow may not result in Vault shares being issued and may not be recoverable through the standard Vault interface.
Users should deposit only through the official AQUA Market interface and verify the network, asset, and transaction details before confirming a transaction.
Share Token
When users deposit USDC, they receive aqUSDC Vault shares.
Each aqUSDC share represents a proportional claim on the USDC Vault’s recognized assets. The number of shares issued is determined using the Vault’s current accounting exchange rate, subject to applicable fees, rounding rules, and ERC-4626 conversion mechanics.
Base yield accrues through changes in the Vault share price.
When the Vault generates positive net returns, each aqUSDC share may become redeemable for more USDC. Strategy losses, fees, or negative valuation changes may cause the share price to decline.
Vault shares do not rebase, and Base APY is not distributed through a separate reward token.
For instant withdrawals, shares are burned when the withdrawal transaction is completed.
For queued withdrawals, shares are burned when the withdrawal request is submitted. The corresponding USDC is transferred later, after sufficient liquidity has been prepared and the withdrawal becomes claimable.
Yield and Strategy
The USDC Vault may display yield in two separate components.
Base APY
Base APY represents the annualized historical or indicative performance generated by the Vault’s approved strategies.
Base yield may include:
Interest generated through AQUA lending markets
Supply interest from approved external lending markets
Returns from approved fixed-rate or fixed-term strategies
Other disclosed USDC-denominated strategy returns
Base APY accrues through the aqUSDC share price and is displayed net of the applicable performance fee unless otherwise stated.
Base APY is variable and may increase or decrease depending on market conditions, utilization, strategy performance, liquidity, fees, and recognized valuation changes.
Boost APY
Boost APY represents additional yield distributed through time-limited incentive programs, protocol rewards, or ecosystem campaigns.
Boost APY is displayed separately from Base APY and does not accrue through the Vault share price unless explicitly stated.
Boost programs may be adjusted, extended, suspended, or discontinued according to their applicable campaign terms.
Displayed APY is not a forecast or guarantee of future performance.
Strategy Allocation
The USDC Vault may allocate deposited assets across multiple approved strategies in accordance with its allocation policy.
Each strategy may be subject to:
Absolute allocation caps
Relative allocation limits
Liquidity requirements
Strategy-specific risk limits
Governance or curator approval
Reporting and valuation requirements
The initial production strategy composition will be disclosed before deposits are enabled.
TBD
TBD
Actual allocations may change over time due to market conditions, borrowing demand, withdrawal demand, strategy performance, available liquidity, and configured risk limits.
A target allocation is not a guarantee that the Vault will continuously maintain that allocation. Assets may remain undeployed or be reallocated when required for liquidity, risk management, or operational purposes.
Only approved and disclosed strategies may receive Vault assets.
Key Risks
Depositing into the USDC Vault involves risk, including the possible loss of principal.
USDC Risk: USDC may lose its intended value due to issuer, reserve, banking, liquidity, redemption, or regulatory events.
Strategy and External Protocol Risk: Approved strategies or third-party protocols may underperform, experience losses, become illiquid, or fail.
Liquidity Risk: The Vault may not have enough immediately available USDC to satisfy all withdrawals. Users may need to use the T+1 withdrawal queue, and settlement may take longer than expected.
Smart Contract and Valuation Risk: Contract vulnerabilities, stale NAV data, incorrect accounting, or oracle failures may affect share pricing, deposits, or withdrawals.
Operational and Regulatory Risk: Vault operations may be affected by reporting delays, role management, emergency controls, compliance requirements, or regulatory restrictions.
