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.

Web3 Backend & Integrations - Frequently Asked Questions

Why do I need a specialized Web3 backend layer?
While on-chain logic is deterministic, real-world systems are not. A Web3 backend bridges this gap by handling API rate limits, transaction retries, provider failures, and ensuring that your off-chain databases stay perfectly synced with on-chain states.
What kind of third-party providers do you integrate with?
We build adapters for the entire digital asset stack. This includes enterprise custody providers (like Fireblocks or Copper), fiat on/off ramps, KYC/AML compliance vendors, blockchain RPC nodes, and analytics platforms.
How do you handle transaction failures or network congestion?
We implement robust workflow orchestration. This involves automated retry mechanisms, dynamic gas and fee pricing strategies, idempotency keys to prevent double-spending, and fallback RPC routing to ensure critical operations succeed even under heavy network load.
Can you integrate blockchain data into our existing traditional systems?
Yes. We design custom indexing hooks and data pipelines that listen for specific on-chain events and transform them into standard webhooks or database updates. This makes blockchain data seamlessly accessible to your existing ERP, accounting, and reporting tools.
