Withdrawals

How to Exit Your Position

All Vault withdrawals use WithdrawalNFT with a waiting period before asset release.

Withdrawal Timeline

Vault	Waiting Period
mMITOc	7 days
mMITOs	7 days
gmMITO	14 days

Step-by-Step Guide

Request Withdrawal

mMITOc

// By asset amount
function withdraw(uint256 assets, address receiver, address owner)
    returns (uint256 shares)
 
// By share amount
function redeem(uint256 shares, address receiver, address owner)
    returns (uint256 assets)

What happens:

Your tokens (mMITOc/mMITOs/gmMITO) are burned
Asset amount calculated at current exchange rate
WithdrawalNFT minted to your address

Receive WithdrawalNFT

You'll receive an ERC721 NFT containing:

struct WithdrawalRequest {
    address authority;     // Vault that minted this NFT
    uint48 maturity;       // When you can claim
    uint256 assetAmount;   // Assets to receive
    uint256 shareAmount;   // Shares that were burned
}

Wait for Maturity

mMITOc / mMITOs: 7 days
gmMITO: 14 days

mMITOc Warning

Slashing can occur during the waiting period!

Request: Expected 100 WMITO
↓ 10% slashing during wait
Actual: Receive 90 WMITO

The exchangeRateHistory tracks slashing timing to calculate your final amount.

Claim Assets

mMITOc / gmMITO

function claimWithdraw(uint256[] calldata tokenIds) external

Batch processing supported - claim multiple NFTs in one transaction (limited by maxClaimsPerTx).

FAQ

Can I cancel a withdrawal?

No. Share tokens are burned at request time. The process is irreversible.

What if I don't claim after maturity?

No penalty. Your NFT remains valid indefinitely. Claim whenever you want.

What if I sell the NFT?

The buyer receives the assets after maturity. This is useful for getting instant liquidity by selling at a discount on NFT marketplaces.

Can I make multiple withdrawal requests?

Yes. Each request mints a separate NFT. You can have multiple pending withdrawals.
