Where it lands in your stackWhat breaks today, and what stays apart here
No other axis of the institutional stack is left out, and every row maps to a mechanism with a stated status. Nine systems every institution runs, the problem each one produces every week, and the answer FxChain is built to give - one grammar of authority, evidence, refusal and settlement truth across the whole stack, not a product per problem.
01
Payment hub and rail gateways
What breaks today
Payments sit in "pending" for hours; confirmations do not match; reconciliation breaks are settled by e-mail and screenshots.
What stays apart here
The settlement truth vector: executed, finalised, delivered on the rail, legally effective, economically complete - five facts, each with its evidence, and missing evidence recorded as missing, never as false.
02
Treasury and TMS automation
What breaks today
API keys carry standing authority; bots and agents act without a bounded mandate; entitlements sprawl faster than reviews.
What stays apart here
A key is not a mandate. Authority is a capability with scope, amount and time that can only narrow; an exhausted mandate leaves a valid key with no power, and a refusal sealed for the auditor.
03
Custody and securities settlement
What breaks today
A "settled" flag hides a cash leg still pending on a bank rail and a legal effect nobody has confirmed.
What stays apart here
Delivery versus payment kept as separate facts, sealed separately, with the external rail an external claim bound by reconciliation rather than assumed.
04
Finance operations and reconciliation
What breaks today
Evidence is scattered across ten systems; disputes are argued from logs nobody sealed; the reason for a refusal is lost or over-disclosed.
What stays apart here
Receipts of what execution observed; denials with a public reason class and claimant-scoped detail; a refusal that travels to the auditor with its rule, its missing evidence class and its remediation path.
05
Compliance and screening
What breaks today
Legal judgement is coded into transaction systems; audit trails are reconstructed after the fact; nobody can say why a rule was active at a given moment.
What stays apart here
A compliance determination is an external claim with a source, an epoch, a disclosure class and a revocation; the protocol verifies its presence and binding, never performs legal judgement; bitemporal lineage answers "why was rule R active at coordinate C".
06
Internal control and change management
What breaks today
Nobody can prove which software version ran, under which controls, with which evidence - a green pipeline is taken for a proof.
What stays apart here
The acceptance discipline, practised on every crossing: falsifiers, negative controls, hostile review; and the Sovereign Assurance & Attestation programme (SAA) to make the version, its controls and its evidence verifiable.
07
Risk, limits and collateral
What breaks today
Risk scores silently become authority; a better score unlocks more; incomparable models are averaged into one number.
What stays apart here
Risk is attributed evidence that may constrain exercise, never expand a grant; integer tiers, not floating-point formulas in consensus; incomparable dimensions stay incomparable; every change of power carries its duty.
08
Data platforms and regulatory reporting
What breaks today
Warehouses and dashboards are treated as sources of truth; views drift from the ledger; nobody can rebuild a report from first principles.
What stays apart here
Canonical truth and projections are different species: every view is reconstructible and non-authoritative by type; state itself is a projection over sealed evidence, and a preserved history can be rebuilt through two independent paths.
09
Incident management and audit
What breaks today
Incidents are closed by a ticket; the same failure returns; history is rewritten to fit the current system.
What stays apart here
Every material incident becomes a reproducer, a negative control and a permanent regression vector with a signed law disposition; sealed history is never rewritten - a correction is a new artifact.
Why this is a system, not a feature list
The nine answers above are the same four objects seen from nine desks: a capability that can only narrow, evidence judged before anything computes, a refusal sealed as a result, and settlement kept as five facts. That is what makes the coverage complete and transverse - and it is why a mechanism proven in one row is already the mechanism the next row needs.
Statuses are stated per row. What is proven today is proven on the local development line; what is direction is research in the architecture programme. No service operates, and no row above is an offer.
