## State Modifications
* Accumulated rewards for active claims are transferred from the `kavadist` module account to the users account as vesting coins
* The number of coins transferred is determined by the multiplier in the message. For example, the multiplier equals 1.0, 100% of the claim's reward value is transferred. If the multiplier equals 0.5, 50% of the claim's reward value is transferred.
* The corresponding claim object is reset to zero in the store
