    Function configuredRates

    • Builds the production CREDIT-to-USD rate source from a deployment's configured rates, replacing the 1:1 dev placeholder. Each returned rate carries a rateId naming the exact rate so a transaction can record which one it priced against.

      Same-currency conversion returns 1:1. Only CREDIT and USD exist, so any other pair is a wiring bug and throws.

      Construction asserts buy >= par >= payout (each read as USD per credit across its own scale) and throws CONFIG.INVALID when the order fails: a credit that could cash out for more than it was bought or backed at would drain the platform, so a misconfigured deployment fails at wiring, not at the first cash out.

      Parameters

      • config: RatesConfig

      Returns Rates

      // Example rates: buy at ~120 credits/USD ($0.00833), backed and cashed out at ~200/USD ($0.005),
      // a ~40% spread:
      const rates = configuredRates({
        buyRate: 8333n, buyScale: 6,
        parRate: 5n, parScale: 3,
        payoutRate: 5n, payoutScale: 3,
      });

      Rates for the dual-rate credit economy this rate source feeds.
