A Transmuter position locks alUSD until a maturity counted in blocks, converting a little every block, and a claim pays out the converted part in mixUSDC. The holder can claim before maturity: the claim then hands back the part not yet converted as alUSD, less an early exit fee, so claiming early gives up converting that part and pays the fee on it. Every figure here is one of the Transmuter’s events, replayed, or arithmetic over them; none is read from the contract at a block.

This claim came 1,757,500 blocks before maturity, when 10.9% of the blocks from the stake to its maturity had passed. So 545.67 alUSD had converted and was paid out as 537.04 mixUSDC. Of the 4,454.33 alUSD still to convert, 4,409.79 came back as alUSD and the Transmuter kept 44.54 alUSD, 1%, as its early exit fee. The claim’s card below carries the arithmetic.
