Normalized events, decoded logs, and reliable webhooks—data layers that abstract chain quirks from product teams.

Query chains like databases—decoded events with reorg awareness your app can trust

We run dedicated nodes or partner RPCs with reorg-safe cursors—indexed state survives chain reorganizations without double-counting transfers. Contract ABIs decode logs into typed rows; historical backfills replay deterministically for new deployments. GraphQL and REST endpoints power dashboards and risk engines—webhooks push confirmations when finality thresholds your risk team sets are met.

02 // ENGINEERING

Development process

Structured phases—from discovery to launch—with clear ownership and handoff points.

Contract set (weeks 1–3)

ABIs, events, finality rules, data retention.

MVP (weeks 3–12)

One chain, core tables, API, backfill job.

Hardening (weeks 10–16)

Reorg tests; load tests; paging limits.

Customers (weeks 14–22)

SDKs; webhook signing.

Operate (ongoing)

New chains; hard forks; schema migrations.

05 // PRODUCT SCOPING

Choosing your path

Two engagement models—start lean and iterate, or commit to a full platform build from day one.

MVP

Speed & essentialism

Phase 1
MVP: single chain indexer, decoded ERC-20/721 events, REST/GraphQL, API keys, reorg handling, historical backfill. Excludes full cross-chain unified model and petabyte analytics warehouse. Proves reliability before multi-chain sprawl.
Recommended

Full product

Enterprise maturity

All-in
Enterprise chain data: multi-chain unified schema, private chain support, streaming to Kafka, SOC2, dedicated clusters, custom decoding plugins.

06 // PARTNERSHIP

Why work together

A single accountable partner across strategy, build, and go-live—not a revolving door of vendors.

John Hambardzumian
Direct collaboration

End-to-end ownership: discovery, architecture, implementation, and launch—with clear communication and production-grade engineering.

  • Discovery & alignment
  • Systems that scale
  • Implementation depth
  • Clear comms

07 // CLARITY

Frequently asked

Dedicated deployments with custom schemas and SLAs—control vs shared network trade-offs.
