BaaS / Sponsor-Bank Oversight & Readiness

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Provider selection > FBO account structure > ledger architecture > BSA/AML control mapping > sponsor-bank readiness score.
