Canonical event before trigger.
A callback begins with a retained platform transition—not a screen scrape, polling race, or mutable downstream interpretation.
NO SHADOW EVENT SOURCECANONICAL EVENTS · SIGNED CALLBACKS · RECONCILED OUTCOMES
Hybrid-Chain turns canonical wallet, settlement, payment, market, identity, data, and compliance events into signed, policy-governed callbacks—without letting downstream automation become a competing source of truth.
THE AUTOMATION PRINCIPLE
A callback begins with a retained platform transition—not a screen scrape, polling race, or mutable downstream interpretation.
NO SHADOW EVENT SOURCEBind event type, filters, endpoint, constants, signature version, timeout, retry, and enabled state before dispatch.
NO UNBOUNDED CALLBACKSRetain response class, latency, attempt, schedule, acknowledgement, dead-letter state, and terminal outcome.
NO INVISIBLE FAILURESONE EVENT IN ACTION
Select each stage to follow one canonical event through routing, signature, delivery, retries, and terminal reconciliation.
TRIGGER ACCEPTED
FAILURE AS DATA
Timeouts, non-2xx responses, invalid destinations, disabled endpoints, secret rotations, and exhausted attempts remain first-class operating records instead of disappearing into background workers.
Open Automation Studio ↗SIX ACCOUNTABLE BOUNDARIES
The platform keeps authority, policy, state transition, delivery, and evidence separate—then connects them through retained commitments.
Accept only retained platform transitions with stable identifiers, types, versions, references, and creation time.
Bind event type, exact filters, destination, constants, enabled state, and rule version.
Register destination ownership, HTTPS posture, encrypted secret, signing version, and rotation lineage.
Retain payload commitment, timestamp, signature context, latency, response class, and error category.
Use deterministic backoff, idempotent event identifiers, finite attempts, and explicit dead-letter outcomes.
Resolve every route to a terminal state and expose the complete operating history to authorized users.
BUSINESS APPLICATIONS
React to canonical state without creating a second truth. Adopt the control plane directly, embed the APIs, or connect the evidence surface to an existing customer experience.
Connect payments, settlement, identity, asset, and account events to ERP, CRM, treasury, and reporting systems.
React to wallet posture, compliance holds, market conditions, stale evidence, and policy exceptions.
Deliver stable signed event envelopes to merchants, institutions, data providers, and product partners.
Update user workflows, notifications, fulfillment, onboarding, and lifecycle communications from canonical state.
Route accepted machine evidence, threshold alerts, maintenance states, and retention events.
Give operators one delivery ledger for investigation, replay decisions, retries, and downstream acknowledgements.
ONE PLATFORM FABRIC
Each product consumes canonical identity, policy, state, and evidence without duplicating the responsibility of adjacent Hybrid-Chain modules.
Trigger fulfillment, receipts, merchant reporting, reconciliation, and customer communications.
Route case state, credential rotation, exceptions, approval requests, and transfer decisions.
Deliver price, feed, order, barrier, strategy, lifecycle, and payout events.
React to evidence ingestion, integrity failures, funding milestones, wallet health, and finality.
HONEST OPERATING BOUNDARY
A signed callback proves what Hybrid-Chain sent; it does not make arbitrary downstream code safe. Production receivers must verify signatures and freshness, process idempotently, protect secrets, authorize side effects, reconcile local outcomes, and isolate failures from value-moving authority.
Register destinations, subscribe to canonical events, rotate secrets, test receivers, and inspect attempts.
Track acknowledgement, deterministic backoff, exhaustion, and complete delivery state.
Every consumer remains responsible for authorization, idempotency, secret protection, transactionality, and local audit.
