/**
 * Encodes a Midnight mempool payload submission transaction.
 *
 * App make-offer flows should call `getOffersData`, gather the returned
 * requirements, then call the output `buildTx(signatures)`. Use this builder
 * directly only when the payload has already been encoded with ratifier data
 * and the caller wants to submit those bytes to the mempool contract.
 *
 * @param params.chainId - Chain id used to resolve `MidnightMempool`.
 * @param params.groups - Group ids included in the payload.
 * @param params.root - Offer tree root committed by the maker.
 * @param params.maker - Maker whose offers are submitted.
 * @param params.ratifier - Ratifier address shared by the offer tree.
 * @param params.ratifierType - Ratifier route used to build the payload.
 * @param params.offers - Number of non-padding offers in the payload.
 * @param params.payload - Encoded mempool payload bytes.
 * @param params.metadata - Optional analytics metadata appended to calldata.
 * @returns A deep-frozen `Transaction<MempoolSubmitOffersAction>` targeting `MidnightMempool`.
 * @throws {InvalidTreeError} when `offers <= 0`.
 * @example
 * ```ts
 * import { MidnightPayload } from "@morpho-org/morpho-sdk/utils";
 * import { mempoolSubmitOffers } from "@morpho-org/morpho-sdk";
 *
 * const payload = await MidnightPayload.encode(items);
 * const tx = mempoolSubmitOffers({
 *   chainId: 8453,
 *   groups,
 *   root: tree.root,
 *   maker,
 *   ratifier,
 *   ratifierType: "ecrecover",
 *   offers: tree.offers.length,
 *   payload,
 * });
 * ```
