Belt.fi v2's Multi-strategy system does not charge fees on its own but has fees based on the strategy protocols used by the vaults. Any unused fees will be capital to pool.
Fundamentally, Belt.fi BeltMultiVaults do not take any entrance fees to our own contract. Any entrance fees arising are those of the strategy protocol at time of deposit.
Deposits in our vaults happen through one of two processses:
This is an immediate, direct deposit to a strategy protocol's vault/pool. Belt Finance itself does not charge any fee and any fee that does arise is the entrance fee for that particular protocol.
This is a delayed deposit to a strategy protocol/pool to save on gas fees by spreading it out over multiple deposits. In this case, a conservative estimate of the entrance fee to the protocol is calculated and is initially charged.
Currently, the entrance fee ranges from 0% to 0.11%, depending on the strategy used at the time of deposit.
Any unused entrance fees will be capital to pool.
Fundamentally, Belt.fi BeltMultiVaults do not take any withdrawal fees to our own contract.
If a strategy protocol used at time of a withdrawal does charge an exit fee, there will be a withdrawal fee as per that strategy protocol's rules. Withdrawal fees are variable depending on the status of the multi-vault pools to keep the ratio of the pool stable.
If there is the possiblity of an extra fees arising of a strategy protocol's withdrawal, the Belt Strategy contract will reserve a small a withdrawal fee to hedge against it. Any unused withdrawal fees will be capital to pool.
Currently, the withdrawal fee ranges from 0% to 0.06%, depending on the strategy used at the time of withdrawal.
