Please note that 1/10 MELT mined are released immediately and the rest 9/10 are linearly released every 6 days in 54 days. The release contract will only be triggered once you make the claiming request by clicking 'claiming rewards'. For example, when you make the 1000 MELT withdrawal request, 100 will be claimable immediately and 900 is moving into the vesting contract. The next time when you clicking 'claiming rewards' again, the total claimable part = previously released MELT (according to the releasing schedule) + 1/10 of the newly mined MELT.
