n15 Tellingly, while the Court's opinion celebrates fraudulent conveyance law and state foreclosure law as the "twin pillars" of creditor-debtor regulation, it evinces no special appreciation of the fact that this case arises under the Bankruptcy Code, which, in maintaining the national system of credit and commerce, embodies policies distinct from those of state debtor-creditor law, see generally Stellwagen v. Clum, 245 U.S. 605, 617, 62 L. Ed. 507, 38 S. Ct. 215 (1918), and which accordingly endows trustees with avoidance power beyond what state law provides, see Board of Trade of City of Chicago v. Johnson, 264 U.S. 1, 10, 68 L. Ed. 533, 44 S. Ct. 232 (1924); Stellwagen, 245 U.S. at 617; 11 U.S.C. @@ 541(a), 544(a).
