Alchemy excels at providing a hyper-reliable, feature-rich gateway to the expansive EVM ecosystem, which commands over $100B in Total Value Locked (TVL). Its strength lies in a mature suite of developer tools—like the NFT API, Webhooks, and enhanced transaction tracing—that abstract away blockchain complexity. For example, its eth_getTransactionReceipt enhancements provide deeper gas and event data, crucial for dApps like OpenSea and Aave that require high-fidelity data.

Alchemy vs Helius: EVM vs Solana RPCs
A technical comparison for CTOs and architects choosing between the leading RPC providers for Ethereum/EVM and Solana ecosystems, focusing on infrastructure trade-offs.

introduction
THE ANALYSIS
Introduction: The RPC Infrastructure Battlefield
A head-to-head comparison of the leading RPC providers for the two dominant smart contract ecosystems.
Helius takes a fundamentally different approach by architecting its infrastructure natively for Solana's high-throughput, parallelized environment. This results in a trade-off: while it doesn't serve the multi-chain EVM market, it delivers superior performance for Solana-specific needs like real-time transaction simulation and custom webhook triggers for on-chain programs. Its RPC nodes are optimized for Solana's 3,000+ TPS potential and unique account-based data model.
The key trade-off: If your priority is building on the established, multi-chain EVM landscape with a vast tooling ecosystem, choose Alchemy. If you prioritize maximizing performance and accessing deep, native tooling for the high-speed Solana blockchain, choose Helius. Your choice is less about a generic 'best' provider and more about committing to an underlying architectural paradigm.

PROS AND CONS
Alchemy vs Helius: EVM vs Solana RPCs
Key strengths and trade-offs for enterprise blockchain infrastructure. Use this to decide between the dominant EVM provider and the leading Solana specialist.
01
Alchemy: EVM Dominance & Maturity
Deep ecosystem integration: Supports 20+ EVM chains (Ethereum, Polygon, Arbitrum, Base) with a unified API. This matters for teams building multi-chain dApps or requiring proven stability for high-value DeFi protocols like Aave and OpenSea.
Superior developer tooling: Offers advanced APIs like alchemy_getAssetTransfers and alchemy_getTokenBalances that abstract complex blockchain data logic, significantly reducing backend development time.

Alchemy: Enterprise Reliability & Support
Institutional-grade infrastructure: Offers dedicated nodes, enhanced APIs, and a 99.9% uptime SLA backed by a $10.5B valuation. This is critical for applications processing billions in TVL where downtime equals direct financial loss.
Comprehensive observability: Provides detailed dashboards for request analytics, error rates, and webhook management, giving engineering teams full visibility into their RPC performance and costs.
03
Helius: Solana-Native Performance
Optimized for Solana's architecture: Built from the ground up for high-throughput, parallel execution. Offers enhanced methods like getAsset and getPriorityFeeEstimate that are essential for building performant NFT marketplaces (e.g., Tensor) or high-frequency trading bots on Solana.
Superior data access: Provides direct, WebSocket-based access to Solana's Geyser plugin for real-time account updates, which is often faster and more reliable than standard RPC methods for tracking wallet states.

04
Helius: Cost Efficiency & Flexibility
Transparent, usage-based pricing: Often 30-50% cheaper than competitors for equivalent Solana throughput, with clear per-request costs. This matters for scaling consumer dApps with unpredictable traffic, like gaming or social platforms.
Specialized tool suite: Bundles RPC with Solana-specific tools like webhooks for on-chain events, a enhanced devnet with faucets, and the helius-rpc client for optimized querying, reducing the need for multiple vendor contracts.
05
Alchemy: The EVM Tax
Higher cost for scale: Premium APIs and dedicated nodes command a significant premium. Teams requiring high request volumes (>100M/month) can see costs escalate quickly compared to raw node operation or niche providers.
Solana as a second-class citizen: While Alchemy supports Solana, its tooling and optimization are not native. For advanced Solana features (e.g., Versioned Transactions, state compression), you may still need Helius or other Solana-native tools.
06
Helius: The Solana Lock-in
Single-chain focus: Excellence on Solana comes at the expense of multi-chain support. If your roadmap includes Ethereum L2s (Optimism, zkSync) or other non-Solana ecosystems, you must manage a second RPC provider, increasing complexity.
Younger platform risks: As a newer company, enterprise support structures, long-term SLAs, and battle-tested reliability at the scale of Alchemy's Ethereum infrastructure are still being proven, which may concern risk-averse institutions.

THE ANALYSIS
Final Verdict and Strategic Recommendation
Choosing between Alchemy and Helius is a foundational decision that hinges on your protocol's core blockchain and architectural priorities.
Alchemy excels at providing a robust, feature-rich gateway to the expansive EVM ecosystem because of its deep integrations and proven reliability. For example, its Supernode infrastructure supports over 97% uptime and powers major protocols like OpenSea and Aave, offering critical tools like the Mempool Streamer, Debug APIs, and NFT APIs that are essential for complex dApp development on Ethereum, Polygon, and Arbitrum.
Helius takes a fundamentally different approach by specializing exclusively in high-performance Solana RPCs and data services. This results in a trade-off: you sacrifice multi-chain versatility for unparalleled speed and low-latency access to Solana's unique architecture. Helius's enhanced APIs, like the WebSocket and Geyser plugins, are optimized for Solana's 3,000+ TPS and sub-second finality, providing a critical edge for high-frequency trading apps and real-time gaming on Solana.
The key trade-off: If your priority is building on the established EVM ecosystem with its massive $50B+ DeFi TVL and need enterprise-grade reliability and tooling, choose Alchemy. If you prioritize maximizing performance and developer experience for a Solana-native application that demands ultra-low latency and direct access to Solana's unique data structures, choose Helius. Your chain choice dictates your provider.
