Alchemy
Developers route their application requests—such as reading ledger states, broadcasting transactions, or streaming mempool data—through Alchemy’s node infrastructure rather than running self-hosted validator nodes.
What is Alchemy?
Alchemy brings together chain apis and data apis. Standard JSON-RPC methods, WebSockets for real-time event subscriptions (pending transactions, logs, new blocks), Trace APIs, and Debug APIs. Unified, indexed data endpoints including the Portfolio API, Transfers API, Prices API, and NFT API.
Its documented workflow includes: Users (typically developers or teams building applications) onboard by signing up on the official website to create an account. Once registered, users generate a unified API key to interact with blockchain networks. The documentation provides step-by-step guides for connecting to supported networks, querying data, and integrating SDKs (such as the Alchemy SDK for JavaScript/TypeScript, Python, etc.).
The platform documentation describes wallet access this way: Alchemy provides Account Abstraction and Smart Wallet infrastructure for developers to implement smart contract-based accounts within *their own* dapps (enabling features like gas sponsoring and session keys).

Unified, indexed data endpoints including the Portfolio API, Transfers API, Prices API, and NFT API.
Webhooks
Automated notifications triggered by onchain events such as transfers, raw transactions, or balance shifts.
Simulation API
Tools allowing developers to preview transaction outcomes and state changes before broadcasting them onchain.
Smart Wallets / Account Abstraction
Infrastructure supporting gas sponsorship, smart contract accounts, and simplified user onboarding flows.
How to use Alchemy

Infrastructure Layer
Developers route their application requests—such as reading ledger states, broadcasting transactions, or streaming mempool data—through Alchemy’s node infrastructure rather than running self-hosted validator nodes.
Data Indexing
Applications query Alchemy's structured data APIs to fetch balances, historical transactions, and token prices programmatically.
Who is Alchemy for?
Alchemy is suited to users looking for chain apis and data apis on Alchemy supports read and write access across 100+ blockchains, including major networks frequently used for token activity such as Ethereum, Solana, Arbitrum, Base, Optimism, and BNB Smart Chain.. Its documented workflow includes wallet funding and balance management.
Before you use it
- Alchemy is strictly an infrastructure and developer tooling provider; it does not execute trades, offer financial advice, guarantee transaction speeds for third-party bots, or feature built-in rug-pull detection tools for memecoins.
- Third-party blogs or social media posts occasionally lump infrastructure providers together with consumer "memecoin sniping bots." Users should distinguish between the underlying infrastructure node provider (Alchemy) and the independent, third-party tradin…
