hi @jasm1n33 thanks for the PR

I am bit confused what fountain fi does, and how it is different from sparkling protocol. So, all the users who have staked BUCK to get sBUCK have deposited all those sBUCK into your protocol?

[jasm1n33]

Hi @g1nt0ki,

Anyone can create a reward pool and add rewards to it on Fountain fi, which is a permissionless process. Users can stake tokens into the pool and consequently earn rewards.

[g1nt0ki]

yes, but who is rewarding them SUI for staking sBUCK?

[jasm1n33]

Anyone can provide SUI rewards for the reward pool in Fountain. Currently, the creator of the sBUCK pool is providing SUI rewards to the pool.

@jasm1n33 refactored and merged here:

#10193

showing it as staking instead of tvl
