introduction
THE ANALYSIS

Introduction: A Cross-Ecosystem Infrastructure Decision

Choosing between Alchemy's EVM dominance and BlockPI's Aptos specialization is a strategic choice between ecosystem breadth and next-generation performance.

Alchemy excels at providing battle-tested, comprehensive infrastructure for the expansive Ethereum Virtual Machine (EVM) ecosystem. Its Supernode platform offers reliable APIs for data, transactions, and WebSockets, serving giants like OpenSea and Aave. With support for over 15 chains including Arbitrum, Optimism, and Polygon, Alchemy provides a unified interface for developers building across the dominant L1 and L2 landscape, backed by industry-leading 99.9%+ uptime SLAs.

BlockPI takes a different approach by specializing in high-performance, low-latency access to the Aptos blockchain. Its globally distributed node network is optimized for Aptos's parallel execution engine, delivering sub-second finality crucial for high-frequency DeFi and gaming applications. This focused strategy results in a trade-off: unparalleled performance on a single, next-generation chain versus Alchemy's multi-chain versatility.

The key trade-off: If your priority is building on the mature, high-liquidity EVM ecosystem with a single SDK for multiple chains, choose Alchemy. If you prioritize maximizing performance, speed, and access to Aptos's novel Move-based architecture for a new application, choose BlockPI. Your decision hinges on whether ecosystem reach or chain-specific optimization delivers more value to your protocol.

CHOOSE YOUR PRIORITY

When to Choose Alchemy vs. BlockPI

Alchemy for DeFi

Verdict: The dominant choice for established, multi-chain EVM DeFi. Strengths: Unmatched ecosystem integration with protocols like Uniswap, Aave, and Compound. Superior tooling for contract debugging, event monitoring via Alchemy Notify, and Webhook support. Highest reliability and data consistency for high-value transactions. Supports Ethereum, Polygon, Arbitrum, and Optimism. Trade-off: Premium pricing model; less ideal for ultra-low-fee requirements.

BlockPI for DeFi

Verdict: A compelling, cost-effective alternative for Aptos and Sui DeFi applications. Strengths: Native, high-performance RPC for Move-based chains (Aptos, Sui). Lower latency and predictable, often lower costs compared to generalized providers. Built for the parallel execution model, offering advantages for high-throughput DeFi primitives. Growing support for EVM chains via its network. Trade-off: Smaller, newer ecosystem; fewer battle-tested integrations than Alchemy's EVM suite.

PROS AND CONS

Alchemy vs BlockPI: EVM vs Aptos

A data-driven comparison of two leading RPC providers, highlighting their core strengths and architectural trade-offs for different blockchain ecosystems.

01

Alchemy: EVM Dominance & Maturity

Deep EVM Integration: Supports 20+ chains including Ethereum, Polygon, and Arbitrum. Offers specialized APIs like alchemy_getTokenBalances and trace_block. This matters for DeFi and NFT projects requiring rich on-chain data and historical state.

Proven Scale & Reliability: Processes 300B+ requests/month with >99.9% uptime. This matters for high-traffic dApps where reliability is non-negotiable.

02

Extensive Tooling Suite: Bundles with Alchemy SDK, Notify webhooks, Mempool watcher, and Enhanced APIs. This matters for teams wanting an all-in-one platform to accelerate development.

Massive Developer Adoption: Used by 70%+ of top Ethereum dApps (Uniswap, OpenSea). This matters for CTOs seeking a battle-tested, community-vetted provider.

03

Alchemy: Potential Drawbacks

EVM-Centric: Limited first-party support for non-EVM chains (e.g., Solana, Aptos). This matters for teams building multi-chain or Aptos-native applications.

Pricing Complexity: Enterprise-tier pricing can be opaque for high-volume use cases. This matters for budget-conscious VPs needing predictable, scalable costs.

04

BlockPI: Aptos & Move Language Specialization

Native Aptos & Sui Infrastructure: Built from the ground up for Move-based chains, offering optimized RPC endpoints and indexers. This matters for protocols launching on Aptos or Sui who need a provider that understands the Move VM.

High-Performance Architecture: Leverages a global distributed node network for low-latency access. This matters for real-time trading or gaming dApps requiring sub-second finality.

05

BlockPI: Flexible & Transparent Pricing

Pay-As-You-Go Model: Transparent pricing based on request volume, often more granular than flat-rate enterprise plans. This matters for startups and projects with variable traffic.

Multi-Chain Support (EVM included): Provides services for Aptos, Sui, and major EVM chains (Ethereum, BSC). This matters for teams operating across both EVM and Move ecosystems.

06

BlockPI: Potential Drawbacks

Smaller Market Share: Less proven at the extreme scale of Alchemy's top-tier EVM traffic. This matters for CTOs who prioritize vendor stability above all else.

Younger Ecosystem: Developer tools and SDKs are less mature compared to Alchemy's extensive suite. This matters for teams that rely heavily on pre-built abstractions and plugins.

Alchemy vs BlockPI

BlockPI: Pros and Cons

Key strengths and trade-offs for EVM and Aptos development at a glance.

01

Alchemy: EVM Dominance

Market leader for Ethereum & EVM chains: Processes over $200B in annualized on-chain transaction value. This matters for protocols requiring deep liquidity, extensive tooling (like Alchemy's NFT API, Notify webhooks), and a proven track record with giants like OpenSea and Uniswap.

02

Alchemy: Superior DevX & Ecosystem

Unmatched developer experience: Features like debug tracing, Mempool streaming, and the most comprehensive documentation reduce integration time. This matters for teams prioritizing rapid iteration and leveraging the full EVM ecosystem of wallets (MetaMask), oracles (Chainlink), and frameworks (Hardhat).

03

Alchemy: Cost & Complexity

Higher cost structure for scale: Pay-as-you-go pricing can become expensive for high-throughput applications (>100M requests/month). This matters for bootstrapped projects or those with unpredictable, spiky traffic patterns where BlockPI's subscription model may offer better predictability.

04

BlockPI: Aptos & Sui Specialization

First-mover in Move-based chains: Offers optimized, low-latency RPC for Aptos (<100ms p95 latency) and Sui. This matters for teams building on these high-performance L1s who need a provider with deep protocol-level expertise and dedicated infrastructure.

05

BlockPI: Predictable Pricing

Simple subscription model: Fixed monthly fees for high request volumes (e.g., 300M requests/month plans). This matters for enterprises and high-growth dApps requiring cost certainty and unlimited requests without overage charges.

06

BlockPI: Smaller EVM Footprint

Less mature EVM offering: While supporting Ethereum, Polygon, and BSC, its tooling (e.g., WebSocket stability, archive data depth) lags behind Alchemy's. This matters for complex DeFi applications on EVM chains that require advanced indexing and real-time data feeds.

verdict
THE ANALYSIS

Final Verdict and Decision Framework

Choosing between Alchemy and BlockPI is a decision between ecosystem depth and multi-chain breadth, with significant implications for your protocol's development velocity and operational scope.

Alchemy excels at providing deep, battle-tested infrastructure for the Ethereum Virtual Machine (EVM) ecosystem because of its extensive tooling and developer-first APIs. For example, its Supernode service offers >99.9% reliability and supports advanced features like WebSocket subscriptions and enhanced APIs for NFTs (alchemy_getNFTs) and transaction simulation, which are critical for high-stakes DeFi protocols on Ethereum, Polygon, and Arbitrum managing billions in TVL.

BlockPI takes a different approach by architecting a high-performance, modular RPC network that natively supports both EVM chains and non-EVM ecosystems like Aptos and Sui. This results in a trade-off: while its EVM tooling may not match Alchemy's maturity, its multi-chain capability provides a unified interface, which is a decisive advantage for teams building cross-chain applications or hedging against ecosystem lock-in.

The key trade-off: If your priority is maximizing development speed and reliability within the dominant EVM ecosystem (e.g., building on Ethereum L2s, using tools like Hardhat and Foundry), choose Alchemy. If you prioritize future-proof, multi-chain architecture and require native support for emerging ecosystems like Aptos (with its parallel execution and Move language), choose BlockPI. Your stack's core dependencies will dictate the optimal path.
