# How it works
### This is a description of the Asymetrix Protocol flow
\
**Step 1. Users deposit their stETH tokens to the Asymetrix protocol**
Once the user deposits to the Asymetrix Protocol, the smart contract mints PST (Pool Share Token) in a 1:1 ratio and sends it to the user's wallet. PST token reflects the user's share in the protocol and is required for withdrawal. \
The minimum deposit amount is 0.1 stETH in the current version of the protocol. However, the deposit does not necessarily have to be a multiple of 0.1 stETH (i.e., 0.11234 stETH is acceptable). \
Please note that the current version of Asymetrix Protocol has a minimum deposit amount of 0.1 stETH.
**Step 2. ETH staking rewards are accumulated in the protocol**
The balance of stETH in the protocol is growing at the current Lido APR speed and updating every 24h.
**Step 3. Yield is distributed to the users**
The draw takes place every 604800 seconds (\~ once a week, this parameter is adjustable by DAO decision). The selected winners are determined using the Chainlink VRF, which is a best practice solution in the crypto space for ensuring provably fair randomness. Your exact odds of winning change dynamically in real-time (see the following [article ](/asymetrix-protocol-guide/users-odds.md)for more information).
By default, the user's initial deposits remain at the protocol for the next draw. No need to re-enter for each draw manually.
**Step 4. How do winners receive their rewards?**
In the case of winning, users automatically receive their rewards in the form of PST (the amount equivalent of stETH), so the user's balance is increased, which automatically increases the odds for further draws. Therefore, there is no need to claim rewards every time. It will be performed automatically.
**Step 5. How to withdraw your initial deposit?**
Users can withdraw their deposits at any time. \
Asymetrix Protocol will burn existing users' PST tokens for stETH tokens at a 1:1 ratio.
*Asymetrix is a non-custodial protocol, meaning that no one except the user is in control of his funds.*
