Network connectivity
Identify the network access, providers, interfaces, and availability assumptions used by the integration.
Blockchain integrations
Connect on-chain activity to the systems your product uses. Define how transactions are submitted and tracked, how events update application records, and how exceptions are investigated.
Explore the integration scopeContact UsAccount for the differences between chain and application state
Data synchronization
Product records need an explicit relationship to the chain events they represent, including when an update is considered ready for use.
Transaction handling
Submitted and completed actions need different treatment. The selected network’s confirmation and finality behavior informs that distinction. Ethereum transaction lifecycle.
System compatibility
Existing interfaces, permissions, and data formats determine what needs adapting.
Integration maintenance
Provider outages, duplicated processing, and incomplete updates need defined handling rather than ad hoc corrections.
Specify the connection from request to reconciled record
Deliverables for implementation and operation
The scope can produce an integration map, event and field mappings, transaction-state rules, implemented connections, test results, and an operating guide. Documentation records dependencies, exception handling, and the information needed to investigate inconsistent state.
Acceptance uses agreed request, event, failure, and recovery scenarios. Integration does not imply that the core application can remain unchanged in every case.
Validate the interfaces before expanding the connection
Review the existing services, contract interfaces, data requirements, and access arrangements. Identify the dependencies that need verification, then build and test the selected integration path.
The release review covers reconciliation, operational visibility, unresolved assumptions, and responsibility for ongoing provider or interface changes.
Agree what happens when processing is interrupted
Specify the supported network and interfaces, event history required, transaction authority, and expected data consistency. Recovery rules and review queues need named owners. Cross-chain bridges, custody, and round-the-clock monitoring require separate scope when relevant.
Illustrative example
Illustrative example: reflect a transfer in a customer account
A backend needs to show an eligible on-chain transfer in an account record. The integration would identify the relevant event, apply the confirmation rule, update the record, and detect duplicate processing. An interrupted update would follow the agreed recovery or review process.
Questions about integrations
Can the existing application stay in place?
The assessment identifies the changes required. Existing components can be reused where their interfaces and behavior meet the integration requirements.
What happens if a provider is unavailable?
The design states how errors, retries, alternative access, or manual investigation are handled within the agreed scope.
Is connecting several chains the same as one integration?
No. Networks and interfaces can require different state, transaction, and operational handling. Coverage and testing are specified for each supported connection.
