Deposits & Withdrawals
This page explains how deposits and withdrawals work across AQUA Vaults.
AQUA Vaults are ERC-4626-based tokenized vaults. When users deposit a supported asset, they receive Vault shares representing a proportional claim on the Vault’s recognized assets.
When users withdraw, their Vault shares are burned and the corresponding underlying asset is returned through either an instant withdrawal or the withdrawal queue, depending on available Vault liquidity.
Deposits
Users deposit the supported asset through the official AQUA Market interface.
Each Vault accepts only its designated deposit asset:
The USDC Vault accepts USDC.
The OXAU Vault accepts OXAU.
Tokens transferred directly to a Vault contract outside the supported deposit flow may not result in Vault shares being issued and may not be recoverable through the standard Vault interface.
Users should verify the selected Vault, asset, network, and transaction details before submitting a deposit.
Deposit Flow
1. Select Vault
Users select the Vault into which they want to deposit.
Before depositing, users should review:
The designated deposit asset
The supported network
Current Vault status
Displayed Base APY and Boost APY, where applicable
Strategy composition and allocation information
Withdrawal conditions
Applicable fees
Relevant risks
2. Approve Asset
Before the first deposit, users may need to authorize the Vault contract to spend the selected deposit asset.
Asset approval is a separate on-chain transaction and may require a network fee.
Users should approve only the required amount unless they intentionally choose a higher allowance.
3. Deposit Asset
After approval, users can submit a deposit transaction.
The number of Vault shares issued is calculated using the Vault’s current accounting exchange rate.
The final number of shares received may be affected by:
The current Vault NAV
Outstanding Vault share supply
Applicable fees
Rounding rules
Virtual-share accounting
Changes in Vault state before transaction confirmation
Any preview shown by the interface is an estimate until the transaction is executed on-chain.
4. Receive Vault Shares
Once the deposit transaction is completed, the user receives the applicable Vault share token.
Vault shares represent the user’s proportional claim on the Vault’s recognized assets.
Base yield accrues through changes in the Vault share price. If the Vault generates positive net returns, each share may become redeemable for more of the underlying asset. Strategy losses, fees, or negative valuation changes may cause the share price to decline.
Vault shares do not rebase.
Deposit Restrictions
Deposits or share minting may be temporarily restricted under certain conditions, including:
The Vault’s deposit capacity has been reached
Deposits or minting have been paused
Applicable off-chain NAV information is stale
Required eligibility or compliance checks are not satisfied
A configured Gate prevents the transaction
Risk controls or emergency mechanisms are active
The Vault is undergoing maintenance or configuration changes
When an off-chain valuation becomes stale, new deposits may be restricted to prevent shares from being issued using outdated valuation information.
If deposits are unavailable, users should review the current Vault status shown in the AQUA Market interface.
Withdrawals
Users withdraw from a Vault by redeeming or burning their Vault shares.
The amount of underlying assets returned is determined using the Vault’s current accounting exchange rate and the number of shares being withdrawn, subject to applicable fees and rounding rules.
AQUA Vaults support two withdrawal paths:
A withdrawal is processed through one path. A single withdrawal transaction is not automatically divided between an instant withdrawal and a queued withdrawal.
If the full requested amount cannot be withdrawn instantly, the user may submit the amount through the withdrawal queue.
Available Liquidity
Instant withdrawal availability is based on liquidity that is immediately available to the Vault.
This may include idle underlying assets held directly by the Vault, after excluding assets that are already reserved or committed to other withdrawals.
Available Vault liquidity is not necessarily the same as liquidity reported by a strategy.
Assets held in a strategy may require:
Deallocation
Position unwinding
Counterparty settlement
Off-chain transfer
Network confirmation
Operational processing
before they become available for withdrawal or claim.
Instant Withdrawal
An instant withdrawal is available when the Vault has sufficient immediately available liquidity for the full requested amount.
When an instant withdrawal is completed:
The user submits the withdrawal transaction.
The applicable Vault shares are burned.
The underlying asset is transferred to the user in the same transaction.
Instant withdrawal availability may depend on:
Idle Vault liquidity
Assets reserved for existing withdrawals
Current withdrawal demand
Strategy allocation
Applicable Gate checks
Vault and network conditions
Availability shown in the interface may change before a transaction is confirmed.
T+1 Withdrawal Queue
When sufficient instant liquidity is not available, users may submit a withdrawal through the T+1 withdrawal queue.
The queue gives the Vault time to recover liquidity from strategies, rebalance assets, and process pending withdrawal obligations.
The standard queue flow is:
For a queued withdrawal, the user’s Vault shares are burned when the withdrawal request is submitted, not when the underlying asset is later claimed.
The applicable withdrawal amount and withdrawal fee, if any, are determined at the request stage according to the Vault’s accounting rules.
Meaning of T+1
T+1 represents the Vault’s standard target processing framework for queued withdrawals. It is not a guaranteed settlement deadline.
Actual processing time may vary depending on:
Strategy settlement periods
Available Vault liquidity
Withdrawal demand
Market conditions
Counterparty or off-chain settlement
Network conditions
Risk controls
Emergency or operational conditions
A queued withdrawal may therefore become claimable earlier or later than the standard target period.
The applicable time basis, cutoff rules, and any Vault-specific processing schedule should be disclosed on the relevant Vault page or interface.
Partial Fulfillment
A queued withdrawal may be fulfilled in whole or in part.
When only part of the pending amount has been prepared, that amount may become claimable while the remaining balance continues to be processed.
The interface may therefore show separate amounts for:
Pending withdrawal
Ready to claim
Already claimed
Remaining unfulfilled balance
Multiple queued withdrawal requests from the same wallet may be aggregated into a single pending withdrawal position, depending on the Vault’s accounting design.
Claim
Once all or part of a queued withdrawal becomes claimable, the user may submit a separate claim transaction.
A claim is an on-chain transaction and may require a network fee.
When a claim is completed:
The claimable amount is deducted from the user’s recorded withdrawal balance.
The underlying asset is transferred to the user’s wallet.
Any remaining pending amount continues through the queue.
The underlying asset is not transferred automatically unless the applicable interface or Vault process explicitly supports automatic settlement.
Withdrawal Status
The interface may display the following withdrawal statuses:
Status
Description
Processing
The withdrawal has been submitted and liquidity is being prepared.
Partially Ready
Part of the withdrawal is available to claim while the remaining amount continues to be processed.
Ready to Claim
The currently fulfilled withdrawal amount is available to claim.
Claimed
The available underlying asset has been transferred to the user’s wallet.
Delayed
Processing is taking longer than the standard target period or requires additional action.
Instant withdrawals are normally completed within a single transaction and may appear directly as completed withdrawal activity rather than as a queued request.
Withdrawal Delays
Withdrawals may be delayed under certain conditions, including:
Insufficient immediately available liquidity
High withdrawal demand
Strategy deallocation or settlement delays
External protocol restrictions
Off-chain transfer or settlement delays
Network congestion
Smart contract or infrastructure issues
Counterparty or custodian disruption
Emergency controls
Applicable Gate or compliance restrictions
A stale off-chain NAV report does not automatically block an existing withdrawal solely because the report is stale. However, stale or delayed valuation information may indirectly affect settlement if strategy assets cannot be reliably valued, recovered, or processed.
Under the standard Vault pause mechanism, new deposits, minting, and allocations may be disabled while withdrawals, deallocations, and claims remain available subject to liquidity and other applicable controls.
Additional emergency measures may affect withdrawal availability if required to protect the Vault or its users.
Users should review the AQUA Market interface for the current withdrawal status and available claim amount.
Important Notice
Deposits and withdrawals are subject to:
Vault liquidity
Strategy settlement conditions
Applicable fees
Share-price calculations
Eligibility and Gate requirements
Risk controls
Network conditions
Operational and emergency procedures
AQUA Vaults do not guarantee immediate liquidity, principal protection, fixed returns, or settlement within a specific period.
Users should review the relevant Vault information, strategy disclosures, fees, withdrawal terms, and risk factors before depositing.
