# Sudoku Staking
**sSDK and uSDK** represents the staked version of $SDK. The main goal for staking is to distribute protocol revenue and emissions from ve(3,3) dexes with stakers.
Stakers will get 90% of the protocol revenue as well as the emissions from deploying the POL on the dex, the remaining 10% will be deposited into the treasury and used for general expenses, audits, marketing and to launch new products/features.\
\
Protocol revenue is generated from taking a fee based on reserve factors for different pools. The more riskier the pool is, the more fees will be generated this way.
There will be 2 different pools for staking. One of them will be sSDK where the rewards will be used for buying SUDOKU from the market and distributing it to sSDK stakers.
The other will be uSDK where the rewards will be used for buying USDC from market and distributing it to uSDK stakers.
Reward tokens are shared with stakers on a weekly basis. When you wish to unstake, there will be 1 week delay. For example, if you staked and want to unstake in 21 February, you will be able to withdraw your tokens in 28 February. This is a precaution for just-in-time stakers.
Revenues will be distributed based on your **share of staked SDK supply.** (For instance, if you have 100k sSDK and there is a total of 1M sSDK, you'll be entitled to 10% of the rewards.)
