Alchemy is a comprehensive Web3 development platform offering a suite of APIs and tools for building and scaling decentralized applications. It provides infrastructure solutions like node management, smart contract development, and analytics for blockchain developers.

Alchemy is a comprehensive web3 development platform that enables developers to build, deploy, and scale blockchain-based applications with unmatched reliability and speed. Designed as the infrastructure backbone for the decentralized web, Alchemy simplifies the complexities of blockchain by providing a robust suite of APIs, node access, smart wallet tools, and custom webhooks. With support for dozens of major chains, including Ethereum, Polygon, Arbitrum, and Solana, Alchemy empowers developers to create scalable dApps, NFT platforms, and DeFi protocols with seamless multichain integration.

Trusted by some of the biggest names in the crypto industry, including OpenSea, Zapper, and Worldcoin, Alchemy has already powered over $100 billion in on-chain transactions and supports more than 100 million users globally. With its focus on developer experience, advanced infrastructure, and enterprise-ready services, Alchemy is leading the charge in bringing blockchain to a billion people worldwide.

Alchemy is a comprehensive Web3 development platform designed to power the next generation of decentralized applications. It enables developers to easily build, deploy, and scale on-chain projects with robust infrastructure and a suite of powerful tools. As the backbone of many major Web3 applications, Alchemy has positioned itself as a leading provider in the blockchain space by supporting over $100 billion in on-chain volume and serving more than 100 million end users across 197 countries.

The platform offers a range of developer-centric products such as Supernode for high-availability node access, Smart Wallets with account abstraction, NFT APIs for token metadata, Token and Transfers APIs for real-time balances and transaction history, Webhooks and Websockets for real-time push notifications, and advanced Subgraph indexing for high-performance custom GraphQL APIs. These are supported by Alchemy’s proprietary infrastructure, which guarantees enterprise-grade uptime, scalability, and low latency.

One of Alchemy’s strongest differentiators is its rollup platform, which enables developers to launch secure, scalable, and customizable Layer-2 solutions with integrations into a growing marketplace. Major projects like Worldcoin have used Alchemy’s rollup infrastructure to scale rapidly. In a market where reliable infrastructure is paramount, Alchemy stands out alongside notable competitors like Infura, QuickNode, Moralis, and The Graph, by offering an all-in-one platform that reduces the need for multiple third-party providers.

Alchemy’s impact on the ecosystem can be seen through its integration with major blockchains including Ethereum, Solana, Arbitrum, Optimism, Polygon, and many more. The platform is tailored for both early-stage builders and enterprise developers, providing extensive documentation, tutorials, and a supportive community via Alchemy University. With its powerful tools, reliability, and educational resources, Alchemy enables developers to focus on building exceptional user experiences instead of managing infrastructure complexity.

Alchemy FAQ

Alchemy Rollups enable developers to launch enterprise-grade rollups on preferred frameworks, giving them full-stack scalability without compromising on security or customization. By using Alchemy’s stack, teams can focus on building user-facing features rather than managing complex backend infrastructure. The platform integrates essential features such as Gas Manager APIs, Bundler APIs, and Account Contracts, drastically reducing time to market for Layer 2 chains and appchains.
Alchemy's Smart Wallets remove major onboarding obstacles like seed phrases and gas fees, letting users start their Web3 journey seamlessly. Using ERC-4337-based account abstraction, these wallets enable sponsored transactions, contract-level security, and smooth integrations with dApps. Whether you're launching a game or a DeFi platform, users can onboard with just an email or device biometrics, eliminating the traditional Web3 learning curve.
Alchemy Subgraphs deliver high-speed, reliable access to onchain data through customizable GraphQL APIs, ensuring zero downtime for mission-critical indexing. When paired with Alchemy Webhooks, teams receive real-time updates on smart contract events, token transfers, and account activity, enabling responsive UIs and backend automation. This setup is ideal for real-time dApps, DeFi dashboards, and token analytics platforms.
Alchemy’s Transaction Simulation allows developers to preview how a transaction will behave onchain before it’s broadcast, reducing errors and avoiding unnecessary gas fees. This is especially critical for apps handling large amounts of funds or smart contracts with complex logic. By catching issues before execution, dApps can offer a safer, more trustworthy experience to users.
Alchemy University is a free, immersive learning platform designed to help newcomers and professionals master blockchain development. From Solidity bootcamps to JavaScript courses tailored for Ethereum, students learn to build full-stack dApps using best-in-class tooling. The curriculum is supported by hands-on tutorials, Discord support, and projects that simulate real-world scenarios.
