A SingleStrategyToken that uses one of the BeltStrategies
A user will receive shares by depositing assets to the SingleStrategyToken contract.
The shares returned will be proportional to the amount the user deposited
A user will receive original assets by turning in shares to the SingleStrategyToken contract
The assets returned will be proportional to the shares returned
The difference between SingleStrategyToken, SingleStrategyToken2:
the first one has some interval in moving assets to the strategy(before that the assets remains in the SingleStrategyToken contract), whereas the second one instantly moves every assets to the strategy.
A MultiStrategyToken contract has multiple strategies
Every one of MultiStrategyToken's strategy is a SingleStrategyToken contract.
A user will receive shares by depositing assets to the MultiStrategyToken contract.
The shares returned will be proportional to the amount the user deposited
A user will receive original assets by turning in shares to the MultiStrategyToken contract
The assets returned will be proportional to the shares returned
Each strategy used in the MultiStrategyToken has a ratio value assigned to it and there are ideal balances for each strategy calculated based on its ratio value assigned
When a user deposits, the assets are moved to a strategy most off from its ideal balance but only accounts strategies whose balances are smaller than its ideal balance (a.k.a most insufficient strategy)
When a user withdraws(turns in shares), the assets are withdrawn from
1. a strategy most off from its ideal balance and whose balances are greater than its ideal balance (a.k.a most sufficient strategy)
2. if the strategy from step 1. did not suffice then a strategy that has the most balance irrelevant from its ratio (a.k.a most locked strategy)
3. if the strategy from step 2. did not suffice, the transaction fails.
