THE BACKTEST

What the rule would have done

A borrower repays when the collateral is worth more than the buyback price at expiry, and walks away when it is not. Below, that exact rule applied to real daily prices for the last two years, across every start date.

PRICED IN

SOL, NOT USD

Both legs of a deal are SOL, so the collateral is divided by SOL on the same day.

LOAN

ADVANCE RATE × VALUE

The loan as a share of what the collateral is worth on day one. Yours to set.

BUYBACK

LOAN × (1 + PREMIUM)

The premium axis. The program only requires buyback > loan.

REPAY WHEN

VALUE(T+TERM) > BUYBACK

The borrower's own interest. The program reads no price to decide it.
