How top teams crushed latency and costs with RPC Fast

1/1

Copy-trading Bot Case Study

Rust-based Solana copy-trading bot • Target: same-slot or +1-slot execution

Request

Land transactions in the same Solana slot or the following one
Maintain 10+ TPS sustained broadcast without hitting rate limits
Keep end-to-end latency (detect → land) under >300 ms
Run on dedicated, co-located infra with sub-1 ms RPC latency

Solution

Execution accuracy: same slot or +1 slot behind the target wallet
Transaction landing: 200–300 ms average, 15 ms lowest recorded
100,000-call stress test: sub-1 ms RPC responses
Shred-level ingestion via Yellowstone gRPC + Jito shred stream

Mizar Case Study

All-in-one CeFi+DeFi trading platform • Cross-chain • Millions of daily requests

Before

No prod-ready Solana/Base nodes; launch needed in days
Risk of missed events and analytics lag
Limited observability; manual ops across chains
Provisioning delays & hardware lead times

After

2× Base + 1× Solana live in 2–3 days
Yellowstone gRPC + bloXroute/Jito → lower latency
Pre-synced spares → ~15-min node swap/scale
Hybrid bare metal + cloud, Grafana & custom gRPC proxy for observability

Anonymous HFT Trading Firm Case Study

Algorithmic trading team on Solana (real-time DEX data; anonymity required)

Before

Gaps & downtime on in-house/public endpoints
Latency spikes under load
Single-endpoint risk; poor visibility
High request load → higher cost

After

Redundant dual nodes (bare metal) + unified endpoint
Near-100% availability, zero data loss
gRPC streaming + Jito + bloXroute → faster books
Fewer RPC calls → lower cost

Aurora Delta Bot MVP Case Study

Solana copy-trading bot project • Single-chain to start • Hundreds of thousands of daily calls

Before

Ran on a mix of public Solana RPCs and a single in-house node with frequent desyncs
Latency spikes during volatile periods caused missed fills and stale copy signals
No clear visibility into RPC errors vs. strategy issues; debugging slowed delivery
Solo DevOps engineer struggled with upgrades, re-syncs, and hardware issues

After

Moved to a dedicated Solana node tuned for trading workloads and stable low latency
More consistent TX landing times during peak volatility, improving strategy execution
Centralized metrics and logs helped distinguish infra problems from bot logic issues
RPC Fast team handles node maintenance and re-syncs, freeing internal engineer time

Baylight Research Corporate Project Case Study

Token flows and DeFi analytics on Solana • Internal dashboards for a small fund • Mixed live + batch jobs

Before

Pulled data from various public endpoints with different behaviors and limits
Occasional lags in fresh data made “near real-time” dashboards unreliable for PMs
Custom scripts monitored lag, but there was no coordinated incident response
Concern that adding more dashboards would break fragile data pipelines

After

Standardized on a managed Solana node setup from RPC Fast for primary workloads
More stable access to current and recent data improved trust in internal dashboards
Monitoring and basic alerting around node health reduced surprise outages
Fund can gradually expand dashboard coverage without redesigning infrastructure each time

HarborSight Dashboard Project Case Study

Solana on-chain dashboards • Validator and DeFi metrics • Mix of live and historical queries

Before

Depended on shared RPCs for both live and historical data; frequent timeouts on heavy queries
Indexing jobs had to pause when public endpoints rate-limited or lagged behind the tip
No reliable snapshot process; any corruption meant multi-day re-sync from scratch
Analysts had to throttle dashboards to avoid overloading infra

After

Switched to dedicated Solana full nodes operated by RPC Fast
Verified snapshots and monitoring reduced re-sync windows from days to hours
Dashboards now run heavier queries without constant query retries and timeouts
Team can iterate on new metrics without worrying about overloading shared infra

HelioFlux Labs MVP Case Study

Private MEV/searcher desk • Solana + Ethereum + Base • Sub-250 ms p95 target

Before

In-house and public endpoints regularly dropped mempool/events under peak load
Single-region infra created latency gaps vs. competitors on Solana and Ethereum
Ad-hoc logging; no clear view into missed bundles or node health
Frequent tuning and firefighting by traders instead of a dedicated infra team

After

Dedicated, low-latency Solana HFT node plus tuned Ethereum/Base endpoints
Multi-region setup (US/EU) with direct node access reduced tail latency by up to 5×
gRPC/WebSocket streaming for real-time order flow with near-zero missed events
RPC Fast team manages optimization, upgrades, and incident response as a service
