# Creampan Finance **Creampan has been discontinued. Frontend services and operations have been sunset. This documentation is retained for historical reference purposes only.** Staking coin is crucial for security of PoS(proof of stake) chain. At the same time, delegators can approximately get 10% yield on their coin with low risk. However, the 28 lockup days is a disadvantage for delegators when we need to access coins. Accessibility is important for crypto asset due to its volatility. Currently, liquid staking protocols provide flexible liquid coin to represent the staked coin. But the reward cannot be claimed until the staked coin is unstaked. At the time of unstaking, the waiting time is still 28 days for delegators. Also, the ratio of liquid coin and the coin itself increase over time, making the DeFi users bear the IL (impermanent loss). Even so, it is still difficult to hedge against the price fluctuation of the staked coin. To further benefit the delegator, stake the coin, and unstake the coin easier for all delegators, we aim to provide liquid staking solution to fully release the power of staked assets. Creampan’s vision is to make crypto real for everyone. ### Liquid stake with Creampan Creampan provides a liquid staking solution that you can mint ptCRO and ytCRO with CRO or WCRO on Cronos chain. The ptCRO is "principal token" of CRO and ytCRO is "yield token" of CRO. The ptCRO is designed to be used freely while the CRO is staked. You can hold, stake, farming, or even sell the ptCRO token when the CRO is staked in the chain. The ytCRO holders will receive "daily CRO reward" of the staked CRO. By separating the principle and yield, both tokens maintain constant price regarding to price of CRO. Therefore, delegators receive the real CRO rewards daily, freely participate DeFi earing opportunities without impermanent loss, and able to hedge against price of CRO by selling their ptCRO and holding ytCRO. ### Flexible Reserves To solve the 28 days unlock time, creampan introduces the flexible reserves concept. The flexible reserves concept is simple idea that contract holds certain percentage of CRO. When delegators want to unstake the CRO, the contract will use the reserves to send fund back to delegators, and then unstake the corresponding amount CRO. After 28 days, the unstaked CRO will be send to the contract to recover amount of the flexible reserves. By doing so, the delegators can unstake without any wait time. If the staking and unstaking rate is quite stable, the reserves ratio of flexible CRO amount to total CRO amount will be constant. However, users should understand that the flexibility actually comes from slightly lower the staking yield compared to the yield with staking CRO fully. For example, the yield of holding ytCRO could be 6\~7% if the reserve ratio is 25%. In our opinion, the 28 days wait time is more valuable than the 3\~4% more yield. The reserve ratio can be determined in governance proposal. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
