Unstake

Regular Unstake

Users can unstake their haSUI to get back SUI freely. The regular unstake operation incurs no fee, but requires a waiting period of 1-2 epochs to cancel the stake.

When a user submits an unstake request, Haedal will burn the submitted haSUI and issue a claim object to the user. When the waiting period finishes, the user (with the specific claim object in account) will be able to claim their SUI tokens back. The amount of SUI tokens that can be withdrawn via unstaking is calculated as:

$$SUIamount=haSUIBurntAmount*haSUIConversionRate$$

There are three scenarios for "Withdraw by Unstake":

• If the unstake request is made at the start of epoch n, the user will receive their staked assets in epoch n+1. However, the haSUI exchange rate for epoch n will not be updated, and the user will receive their assets based on the haSUI exchange rate of epoch n-1.

• If the unstake request is made during epoch n, the user will receive their assets in epoch n+1.

• If the unstake request is made in the last 4 hours of epoch n, the user will receive their assets in epoch n+2.

Instant Unstake

Besides the regular unstake, Haedal also supports SIP33 on Sui to allow for instant unstake. The SIP33 allows inactive StakedSui objects to be redeemed immediately. This creates the premise for instant unstake. Users can opt for instant unstake with a small unstaking fee when they need their SUI urgently.

The instant unstaking fee is currently set as 0.02% of the unstaking amount of each request.
