    Implements read only methods for swap quotes

    The operations in this class assume that the Customer is already validated (both AuthN and AuthZ).

    • Parameters

      • args: {
            db: B2bDatabase;
            jupiterClient: JupiterSwapClient;
            productQuoteService: ProductQuoteService;
            solanaTokenMintAddressService: SolanaTokenMintAddressService;
            solanaTokenService: SolanaTokenQueryService;
        }

      Returns SwapQuoteQueryService

    db: B2bDatabase
    jupiterClient: JupiterSwapClient
    productQuoteService: ProductQuoteService
    solanaTokenMintAddressService: SolanaTokenMintAddressService
    solanaTokenService: SolanaTokenQueryService

    • Build the SwapEstimate from an already-successful engine result's pricing block. Shared by the preview estimate() (fed by the engine's audit-free estimate()) and the authoritative create-time quote(), so both derive target amount + fees identically. The product_quote audit id is intentionally not threaded here — only create() produces one, and it pins that id onto the persisted swap_quote row directly.

      Parameters

      • __namedParameters: {
            quote: QuoteShape;
            sourceAmount: number;
            sourceCurrency: "MOVEUSD" | "USDC" | "SOL" | "WETH" | "WBTC";
            sourceToken: TokenData;
            targetCurrency: "MOVEUSD" | "USDC" | "SOL" | "WETH" | "WBTC";
            targetToken: TokenData;
        }

      Returns Promise<
          | { ok: true; value: SwapEstimate }
          | {
              error:
                  | ServiceError<"INVALID_INPUT" | "INVALID_AMOUNT">
                  | ServiceError<
                      "INVALID_AMOUNT_AFTER_FEES",
                      {
                          fees: Fees;
                          sourceAmount: number;
                          sourceAmountAfterFees: number;
                          sourceCurrency: "MOVEUSD"
                          | "USDC"
                          | "SOL"
                          | "WETH"
                          | "WBTC";
                          totalFees: BigNumber;
                      },
                  >;
              ok: false;

      >

    • Ephemeral (and entity-agnostic) quote of target amount and fees

      Parameters

            targetCurrency: "MOVEUSD" | "USDC" | "SOL" | "WETH" | "WBTC";
        }

      Returns Promise<
