fix:redeem supplier yield via exchange rate - #13
Merged
Conversation
- Supply mints amount / exchange_rate lTokens and withdrawal redeems ltoken_balance × exchange_rate, so borrower interest (net of the reserve slice) reaches suppliers through exchange-rate growth instead of leaking to treasury sweeps. - Track total_supplied in scaled (lToken) units: supply caps project face value before comparing and the reserve slice in accrue_interest becomes exact. - Reset the exchange rate to 1.0 when the market fully drains so the next genesis supply is backed 1:1; it stays grown across debt repayment while supply remains. - liquidate accrues both debt markets so the close factor and health check see principal + accrued interest on each side. - get_underlying_balance quotes lTokens at the exchange rate. - Regression tests for mint/redeem scaling, the underlying-balance view, and the drain-reset rule; docs updated.
