Frankencoin has no price oracle, so nothing states what the SPYon is worth in ZCHF: the collateral bar is in SPYon and the debt bar in ZCHF, each on its own scale, and the two lengths do not compare. The line draws each side on its own scale too, its top labelled in its token.

Every ledger row (the position's MintingUpdate) states its collateral and its debt after it, so each line is exact to the base unit: a row's figure less what the row before left is what it deposited, withdrew, minted or repaid. This position is a clone: its first deposit and mint came in the transaction that cloned it, and are counted as Deposited and minted like any other.

The debt is gross. Each mint adds its whole amount, and its transaction's receipt splits it into what the wallet was paid out, the reserve share (kept in the reserve against this position and returned on repayment) and the interest for the remaining term, paid up front and not returned (Interest paid up front, dashed). Nothing accrues afterwards, so the debt moves only on a row and stays flat between rows. A repayment's receipt splits it into what the payer paid (Repaid) and the reserve share the reserve gave back.

Frankencoin is not in the shared daily price store and needs no price here: between rows each side stays in its token as its last row left it.
