Settlement Endpoint Control Tower
Pre-validating identity-bound settlement endpoints before value moves.
A public reference demo of an endpoint pre-validation control for tokenized settlement. It binds a wallet endpoint to institution identity, legal-entity authority, custody context, and policy evidence, then decides whether the token route is safe to use, preserves the fiat fallback when it is not, and records an audit-ready evidence receipt.
Introduction
A wallet address is not a settlement instruction. Banks govern fiat settlement instructions carefully: who owns the account, which institution services it, which intermediary applies, and how it changes. The Settlement Endpoint Control Tower applies that same discipline to wallet and token endpoints. It is a public reference demo of a pre-validation control that binds a destination endpoint to institution identity, legal-entity authority, custody context, policy evidence, and a preserved fiat fallback, decided and recorded before value moves.
The Problem
A traditional settlement instruction answers 'where does the value go' with reference data the industry has spent decades hardening. A digital coordinate on a token rail answers that question differently, and it asks newer ones: which institution and legal entity control the endpoint, who has authority to maintain it, is the custody and allowlist evidence fresh, is the required beneficiary and Travel Rule context complete, does policy allow this route now, and which fiat fallback remains available. Pasted wallet addresses answer none of that, and those checks do not fit neatly into existing pre-settlement controls.
The Build
The demo models an identity-bound settlement endpoint profile across six layers: institution (BIC, role, jurisdiction), legal entity (LEI and verifiable-authority-style evidence), digital endpoint (wallet, network, token, custody, allowlist status), fiat fallback, controls (freshness, authority, beneficiary data, policy), and trace (route verdict, operator actions, audit events). The browser demo runs four operating views (endpoint profile, pre-validation, route decision, evidence and audit), three deterministic scenarios (blocked endpoint, refreshed endpoint approved, expired authority evidence), and three role views (operations analyst, risk reviewer, four-eyes approver), with a client-side evidence export. The signature moment: the beneficiary and fiat instruction are valid, but the token endpoint lacks current control evidence, so the control tower blocks the token route, explains the gap, preserves the fiat fallback, and emits an audit-ready receipt. The repo also includes a localhost-only SQLite workflow proof and a single canonical quality gate that runs the same checks locally and in CI.
Why It Matters
Banks already know the cost of weak destination data: misdirected payments, manual repair queues, and opaque exception handling. Tokenized settlement raises the stakes, because value can move to a wallet endpoint quickly and with limited recourse. The useful control is not a slower payment. It is a pre-validation step that proves the destination endpoint is ready before value leaves, keeps the fiat fallback available when it is not, and produces evidence for why a route was held.
