Data & Infrastructure
For engineering and operations teams whose applications depend on chain data and network services. OffchainTech scopes how information is collected, reconciled and served, and how transaction operations recover when providers, networks or downstream components stop responding.
Illustrative engineering workflow. Interfaces, environments and responsibilities are assessed for the agreed scope.
01 / SCOPE
Define what each result represents before building a dashboard.
Build indexers for contract events, account activity and transaction tracking, with scoped dashboards, alerts and APIs. Preserve network identifiers, block references and processing checkpoints. Define freshness indicators so users can distinguish current information from delayed or partially indexed results.
Agree confirmation assumptions, event ordering and deduplication keys. Plan how reverted blocks are removed and replacement events are processed. Backfills and replay should be repeatable without duplicating records or silently overwriting information that downstream consumers already used.
Specify schemas, pagination, query limits and error responses for internal or customer-facing consumers. Define retention, access roles and attribution to upstream sources. Reconcile aggregate values with underlying records and document gaps in available history.
02 / SCOPE
A message sent on one chain is not automatically complete elsewhere.
Scope selected network connections, messaging and bridge integrations, including state synchronisation. Specify source confirmation, destination execution and timeout states. Identify third-party trust assumptions, unsupported routes and recovery ownership; adding a connector does not eliminate bridge or network risk.
Track each leg of a multichain operation with correlated identifiers and timestamps. Surface pending messages, failed execution and inconsistent state. Define which retries are permitted, who handles an unresolved transfer and what evidence the operator needs before acting.
Review documented interfaces, historical-data access, quotas and authentication requirements for each dependency. Test response differences and degraded service where practical. Compatibility is confirmed for the selected environment, rather than claimed for every chain or provider.
03 / SCOPE
Infrastructure delivery includes operational decisions and recovery notes.
Assess nodes, RPC services, relayers, oracles and transaction automation. Define ownership, deployment configuration, health signals and resource assumptions. Relayers require explicit signing authority and transaction policies; oracle integrations require clear input provenance, update cadence and stale-data behaviour.
Evaluate narrowly scoped custom chains only against concrete requirements for execution, governance and operations. Document dependencies, upgrade responsibilities and recovery constraints. Custody, legal and commercial decisions remain separate. Security review or audit preparation is not independent certification or an uptime guarantee.
FROM BRIEF TO HANDOVER
Agree networks, data consumers, required history, freshness expectations and operating owners. Document acceptance cases, external dependencies and excluded service commitments.
Implement collectors, processing checkpoints, selected infrastructure and consumer interfaces. Review event provenance and restart behaviour alongside the main data path.
Exercise backfills, repeated events, interrupted processing and provider failures. Check reconciled outputs and recovery evidence in environments appropriate to the selected networks.
Deliver agreed deployment assets, schema documentation, configuration and runbooks. Confirm monitoring ownership, access transfer and separately scoped support arrangements.
BEFORE WE BEGIN
Coverage depends on network history, provider access, data retention and the selected scope. We assess these constraints before agreeing the backfill and acceptance criteria.
No. Fallback can be scoped, but providers may share dependencies or disagree on state. Selection rules, failure behaviour and ongoing operations require explicit testing.
Only under an agreed support scope. Handover identifies who monitors services, approves upgrades, manages access and responds to operational incidents.
