PoolManager

Idea behind the PoolManager is that we hold user’s funds (both SOL and SPL tokens) inside the system on a special account, which is also used for getting staking rewards. Each user/token pair has a unique account for holding funds.

We try to limit Cambrian from exposure to risky assets that could disrupt stability and so there is a separate Mint Validator contract — a whitelisting contract that will allow or disallow certain tokens from being put into the system. In the future we may have those on a per-user basis, but for now it is common for all users.

And TokenManager as part of PoolManager is used to deposit and withdraw free funds into user’s accounts. Since those funds are not staked they can be withdrawn immediately. All the staking rewards also go to this account so they can be staked or withdrawn later on.

When a user deposits funds into Cambrian, PoolManager mint them our token (LRT) cSOL, which will later be burned at the moment when user withdraws restaking assets.
