Usage

import { TranchingMarket } from "@exponent-labs/exponent-sdk";

} from "@exponent-labs/exponent-sdk/client/tranching";

const seedId = new Uint8Array([1, 2, 3, 4, 5, 6, 7, 8]);
const derived = TranchingMarket.deriveAddresses(seedId);

const ix = createInitializeTranchingMarketInstruction(
  {
    payer: wallet.publicKey,

    systemProgram,
    admin: adminState,
  },
  {
    roles: { admin: [admin.publicKey], sentinel: [] },
    riskConfig,
