Unstake

The above figure shows the process of withdrawing the deposited ATOMs through burning snATOMs. User must communicate with the Supernova twice to avoid compromising fairness, which is as follows:

1. Burn snATOMs to request undelegation.
2. Withdraw wATOMs.

Example

Let’s say $user_A$ wants to withdraw $n_w$ wATOMs. The user sends $\Delta l=aL$ snATOMs to the protocol to burn them. The decremental ratio is calculated as $\alpha = n_w/N$. The denominator $\tilde{N}=N+B_O-B_L$ is an estimated value of the total delegated ATOMs to ensure no loss of user assets.

$user_A$ can withdraw wATOMs after the batch plus the undelegation period. In the case of Cosmos Hub Gaia, the batch period is 3 days and the undelegation period is 21 days. Therefore the user must wait at least 21 days and at most 24 days to withdraw wATOMs for the safety of the protocol.

Max Waiting Time

The maximum waiting time is the sum of the batch and undelegation periods. For Gaia, it can be calculated as $min(T_B+T_U)=min(T_B)+U=⌈T_U/M⌉+T_U=3+21=24$. Please refer to section 3.2 Batch Withdraw in page 7 of the whitepaper for details.
