Web3 backend and integrations for production systems

APIs and service layers that connect on-chain logic to real systems: providers, internal tools, and operational workflows. Built for reliability, traceability, and production operations on EVM and XRPL.

What you get

We bridge the gap between deterministic on-chain logic and the messy reality of off-chain systems, ensuring consistency and reliability.

We build the integration layer that makes digital asset products actually run.

Backend services & APIs

+

Service boundaries, workflows, and APIs designed for operations and maintainability. Output: production-ready services with clear interfaces and ownership.

Provider integrations

+

Integrate the providers you choose without lock-in. Output: adapters and workflows for wallets/custody, ramps, compliance vendors, analytics, and exchanges.

Workflow orchestration

+

Handle retries, idempotency, failure modes, and operational control paths. Output: robust workflows that keep systems consistent under real load.

Indexing hooks & data outputs

+

Design events and data flows so ops and reporting are reliable. Output: integration points for indexers, pipelines, and reporting outputs.

Security and access controls

+

Role-based access, key operation controls, and production-safe guardrails. Output: operational controls that protect critical actions.

Production hardening

+

Monitoring, alerting, and runbooks for integration-heavy systems. Output: observability baseline + incident response workflows.
