Blockchain RPC, Indexer & Web3 Infrastructure Development

RPC benchmarking, blockchain indexers, data APIs, monitoring and resilient infrastructure for production Web3 applications.

Engineering the complete production path

Infrastructure quality is workload-specific. A provider that performs well for simple balance calls may fail under log scans, bursty transaction reads or real-time subscriptions. We benchmark the methods that matter, design explicit failover and build data pipelines that can recover from gaps rather than silently returning incomplete state.

Capabilities

What we can build

RPC benchmarking

Reproducible p50, p95 and p99 latency tests, error rates, block lag and regional comparisons by method.

Indexers

Chain-specific ingestion, replay, reorg or fork handling, normalized storage and application-facing APIs.

Reliability

Health scoring, circuit breakers, provider failover, queueing, backpressure and data-gap detection.

Observability

Metrics, logs, traces, alerts and runbooks tied to user-visible service objectives.

Scoping checklist

What to prepare

A short description is enough to begin. These details help us return a useful technical response instead of a generic estimate.

  • Chains, methods and data volume
  • Freshness and consistency targets
  • Regions and hosting constraints
  • Retention, replay and API consumers

Solana Searcher Infrastructure: Colocation, RPCs and Slot Leaders

Winning Jito bundles consistently comes down to infrastructure as much as strategy — this guide covers choosing RPC providers, colocating near Jito block engine endpoints, tracking the slot-leader schedule to pre-route bundles, and the realistic latency budget a competitive searcher needs in 2025.

Hiring a Solana Infrastructure Engineer: What to Actually Look For

Most candidates can configure an RPC node but few understand shred propagation, geyser plugin internals, or NUMA-aware thread pinning — we outline the interview signals, take-home task design, and market-rate ranges for trading-focused infra engineers in 2025.

Searcher Infrastructure for Solana: Colocation, RPC, and Latency

Winning MEV on Solana is as much a hardware race as a strategy game. We compare colocation options near Solana validators, dedicated RPC node setups, and gRPC Yellowstone stream configurations that top searchers use to shave milliseconds.

Building RPC Failover Architecture for Solana Trading Bots

A production walkthrough of multi-provider active-passive failover for Solana trading bots — covering health checks, circuit breakers, and automatic re-routing with HAProxy and a custom health-check sidecar so a single RPC outage never halts your strategy.

RPC & Infra Considerations for Robinhood Chain Trading Bots

Robinhood Chain RPC access, block timing, and Ethereum settlement lag shape how a trading bot actually performs.

Jito Bundles and Private Mempool: MEV Bot Infrastructure on Solana

How Jito's block engine and bundle auction work at the infrastructure level, and what your bot needs to submit competitive bundles without wasting compute. Covers tip selection, bundle landing rates, and monitoring rejected bundles.

Common questions

What does a Apps & Infra engagement start with?+

We begin with a technical discovery covering the target platform, integrations, operating constraints and measurable acceptance criteria. You receive the final scope and quote before payment.

Will we control the code and infrastructure?+

Yes. The agreed source code and deployment are handed over to the client. Production keys and seed phrases remain client-controlled, and access is scoped to the minimum required.

Can you improve an existing system?+

Yes. We can review an existing codebase or architecture, identify reusable components and propose a focused implementation rather than rebuilding everything.

Do you guarantee trading results?+

No. TierZero provides software engineering and infrastructure. Market outcomes depend on strategy, competition, liquidity, fees and risk settings; testing and explicit controls are required before live use.

Describe the system you need

We will review the platform, integrations and operating constraints, then reply with the next technical questions and a scoped delivery plan.
