Overview

Subgraphs define how contract events are indexed into GraphQL-queryable entities using The Graph. We design subgraph schemas around frontend needs, write efficient mappings, handle contract upgrades and multiple deployments, optimise performance and deploy to hosted or decentralised infrastructure.

Common use cases

  • dApp frontend dataQueries for application UIs.
  • Protocol analyticsPublic protocol data APIs.
  • Multi-chain subgraphsSame protocol across chains.
  • Subgraph optimisationImproving slow subgraphs.

Quick answers

Subgraph Development at a glance

The essentials in brief. Every project is scoped individually — ask us for specifics.

What is subgraph development?
Subgraphs for The Graph — schemas, mappings, deployment and optimisation for fast dApp data queries.
Who is it for?
Typically Web3 startups, fintechs adding digital assets, and institutions exploring tokenization, stablecoins or on-chain settlement.
What does Shivacha provide?
  • Schema design
  • Mappings
  • Templates
  • Multi-network deployment
  • Performance tuning
  • Monitoring
Which technologies are used?
The Graph, GraphQL, TypeScript, ClickHouse, PostgreSQL, Apache Kafka — chosen to fit your stack and constraints.
How does the process work?
Data requirements → Indexing design → Pipeline build → Serving layer → Operations.
What affects the cost?
  • Contract complexity and number of chains
  • Custody and wallet model
  • Independent audit scope
  • Indexing, analytics and back-office tooling
  • Compliance integrations (KYC, AML, Travel Rule)
  • Upgradeability and governance requirements
How long does it take?
A focused contract system or dApp MVP typically takes 8–14 weeks plus independent audit time; institutional platforms usually take 4–9 months.
How do I get started?

Delivery

How an engagement runs

  1. 1

    Data requirements

    Chains, contracts, entities, freshness and query patterns.

  2. 2

    Indexing design

    Subgraphs, custom indexers or hybrid, with reorg strategy.

  3. 3

    Pipeline build

    Ingestion, decoding, enrichment and storage.

  4. 4

    Serving layer

    APIs, dashboards and alerts for consumers.

  5. 5

    Operations

    Monitoring of lag, completeness and data quality.

Security

Security built into delivery

Controls we apply by default on this kind of work — not a separate phase at the end.

Specification first

Roles, invariants and threat model documented before code.

Adversarial testing

Fuzz, invariant and fork tests plus static analysis on every change.

Key management

Admin keys in multisig or MPC with timelocks on sensitive actions.

Independent audit

Code prepared for — and we recommend — an external audit before mainnet value.

FAQ

Frequently asked questions

When should we use a subgraph?

For event-driven contract data on supported networks with moderate complexity and volume.

What are subgraph limitations?

Complex computations, trace data and very high volume may need custom indexers.

Should we use The Graph or a custom indexer?

Subgraphs are fast to build for contract-event data on supported networks. Custom indexers suit high volume, multi-chain, trace-level or complex enrichment needs. Many platforms use both.

Can you reconcile on-chain data with our internal ledger?

Yes. Reconciling on-chain activity with internal and custodian records is a core part of our digital asset and fintech work.
