What is Alchemy?
Alchemy is a blockchain developer platform that provides RPC access, data APIs and webhooks. Its pricing page lists compatibility with 100+ blockchains, a free tier of 30M compute units per month and pay-as-you-go usage at $0.525 per 1M compute units.
How Alchemy works
Alchemy runs node infrastructure and APIs behind an app key.
Your code sends standard JSON-RPC calls, and each method is priced in compute units (CUs): eth_blockNumber costs 10 CUs, eth_getBalance 20, eth_call 26, eth_sendRawTransaction 40 and eth_getLogs 60, while txpool_content costs 500. Batch requests are billed as the sum of their methods. Throughput is measured separately in CUs per second over a rolling 10-second window. On top of the Node API sit the Token, Prices, Transfers, Portfolio and NFT APIs, webhooks and websockets.
For wallets, Alchemy provides account abstraction tools: a Bundler API, a Paymaster API and gas sponsorship so your users can transact without holding gas, plus ERC-4337 and EIP-7702 transaction support and transaction batching. Enterprise customers can get dedicated single-tenant clusters, and Alchemy also offers rollup deployment, Solana gRPC streaming and validator services.
How to start with Alchemy
- Sign up at alchemy.com and start on the Free plan without talking to sales.
- Create an app, pick a chain, copy its HTTPS or WebSocket URL, and send requests.
- The multi-chain sandbox in the dashboard lets you try methods first, and faucets hand out testnet tokens.
- Free accounts get standard support with a 48-hour target response time; Pay as You Go targets 24 hours.
- Enterprise requires contacting sales.
Alchemy fees and limits
- Pay as You Go: $0.525 per 1M CUs, 10,000 CU/s (about 300 requests per second) included, and each extra 5,000 CU/s block costs $160 a month up to 30,000 CU/s.
- Gas sponsorship on Pay as You Go carries an 8% admin fee on pre-loaded funds, and Solana gRPC starts at $75 per TB.
Free: 30M CUs a month, 500 CU/s (about 25 requests per second), 5 apps and 5 webhooks, with gas sponsorship on testnets only. Enterprise starts at 1,000 requests per second with volume discounts.
Risks to know before using Alchemy
- You are trusting one provider for chain data.
- If Alchemy has an outage, your app's reads and writes stop unless you configure a fallback RPC.
- Bills scale with the methods you call: a log-heavy indexer using eth_getLogs spends six times the CUs of eth_blockNumber calls, so run the pricing calculator on your real method mix.
- Request logs keep only one hour of history on Free.
- Alchemy says it hosts on AWS, Google Cloud and Cloudflare, runs annual third-party penetration tests and a bug bounty.
