Deposit Flow
A deposit mints the vault's zTOKEN against accepted stablecoins. Two paths exist, both minting the same token.
Instant deposit
Default path for standard deposits
Compliance and slippage checks pass, any fee is separated, and the zTOKEN is minted to the user in a single transaction
Request deposit
Large deposits above the daily instant limit, or where review is required
Stablecoins are held and a pending request is created with no tokens minted, until the fund admin approves at the current rate; rejection returns the funds
Whether a vault offers the instant path, the request path, or both is entirely the fund manager's choice. The contracts support either, so the deposit model is configured to match the vault's strategy and review requirements rather than fixed by the protocol.
Instant Deposit
On the instant path the user sets a minimum acceptable output, so the mint reverts if the NAV moves unfavorably between quote and execution. Deposited capital is then deployed into the vault's strategy by the fund manager and begins generating yield. The full sequence is shown below.
Request Deposit
The request path is used for large deposits above the daily instant limit, or when admin review is required. The user's stablecoins are held by the vault until the request is resolved. Compliance is checked at request creation; on approval the vault mints at the admin-set rate, validated against the oracle within variation tolerance. The flow has two outcomes, approve and reject.
1
User
Call depositRequest(token, amount, referrerId). Stablecoins transferred to the vault. requestId returned.
2
DepositVault
Create a pending request object. No tokens minted yet. Emit DepositRequest event.
3
Admin
Review the request off-chain. Validate source of funds and current NAV.
4a (approve)
Vault Admin
Call safeApproveRequest(requestId, newRate). Rate must be within variationTolerance of the oracle price. If valid, mint zTOKEN to the user and emit ApproveRequest.
4b (reject)
Vault Admin
Call rejectRequest(requestId). Stablecoins returned to the user. No zTOKEN minted. Emit RejectRequest.
