Reference Indexer
The official indexer is the reference data service that powers explorer summaries and derived views on testnet. Interfaces are reference access points; the protocol is the authority. Protocol scope is defined in the protocol overview. It ingests on-chain, time-ordered, tamper-evident events, normalizes them into readable tables, and exposes query APIs for tools. It is non-authoritative, and independent indexers can reproduce the same outputs.
Derived Views
Transforms events into balances, allocations, and coverage summaries for explorers and dashboards.
Query Access
APIs deliver entity, wallet, and commerce data for tools that read the Hub.
Reference Output
Acts as the baseline implementation for parity checks and conformance reporting work.
Open Reproducibility
Independent indexers can match outputs by following the shared schemas and event rules.
Core Coverage
The indexer organizes chain data into searchable surfaces so tools can answer common questions fast. Coverage includes entity registry state, governance actions, wallet flows with tags, evidence anchors, and commerce objects like invoices or recurring plans. Entities retain control of funds; the Hub anchors authority and events. Operations are stablecoin-native; no fiat rails or custody. These surfaces mirror the Hub schema and remain aligned across tools.
Entity Registry
Entity IDs, template types, status, and canonical wallet bindings derived from chain state.
Governance Trail
Proposals, approvals, and authority changes with timestamps and references for verification use.
Wallet Flows
Tagged inflows and outflows with categories, evidence links, and coverage ratios shown.
Commerce Objects
Catalog items, invoices, and recurring plans exposed for apps and dashboards tools.
Pipeline Flow
Keep outputs reproducible across tools by following a consistent indexing loop. Events emit from transactions, indexers normalize them, and views update with coverage signals. Use this flow to debug differences and confirm parity against the reference output.
Ingest Events
Stream blocks, transactions, and events from the Hub through JSON-RPC and indexed logs.
Normalize Data
Map raw events into tables that follow shared schemas and tag definitions.
Publish Views
Update derived views for entities, wallets, governance, and commerce objects continuously today.
Compare Outputs
Compare outputs against the official explorer and reference exports to confirm parity.
Signals and Reliability
Indexers expose signals that show freshness, coverage, and parity across tools. These include ingestion lag, missing tags, and mismatched totals so teams can resolve issues early. Signals support transparency but do not change protocol authority.
Freshness
Lag metrics show the last indexed block so viewers know how current the data is.
Coverage
Coverage ratios highlight missing tags or incomplete flows in a given time window.
Parity Checks
Parity checks compare outputs across indexers and detect mismatched totals or classifications.
Testnet Boundaries
The official indexer is testnet-scoped and evolves with protocol changes. Resets, endpoint shifts, and schema updates can affect outputs between cycles. Treat results as integration signals and verify against the current bundle when publishing.
Reset Cycles
State resets can clear indexed data, so maintain export or snapshot procedures.
Endpoint Shifts
JSON-RPC endpoints may shift between cycles; refresh connections regularly today.
Non-Authoritative
Indexer outputs are derived views; protocol state remains the authority always first.
Manifesto
"My goal is simple: make it possible for anyone, anywhere, to form an entity that can operate with credibility, continuity, and real financial rails, built for stablecoin-native operations."
