Ralph Studio gives developers everything they need to build on Alephium, a managed RPC endpoint, smart contract tooling, real-time analytics, and a growing set of data APIs. If you’ve used Alchemy or QuickNode on Ethereum, Ralph Studio is the equivalent for Alephium.

​
What you can do

RPC Access: connect your app to Alephium mainnet or testnet through a managed endpoint. No node setup, no maintenance. Just create an app, grab your slug, and start making requests. Smart Contract Tooling: write, compile, deploy, and interact with Ralph smart contracts directly in the browser. The built-in IDE supports the full Ralph language with syntax highlighting, error output, and one-click deployment. Contract Registry: verified contracts are published to a public registry. Anyone can browse and interact with them without writing code, similar to Etherscan’s Read/Write Contract feature. Analytics: every request through your endpoint is logged. You get request volume, latency percentiles, error rates, compute unit usage, and per-method breakdowns: all in your dashboard. Data APIs: structured access to indexed onchain data. Query transaction history, token balances, contract events, and block data without parsing raw node responses.

​
How requests work

Every app you create gets a unique slug. Your RPC URL looks like this:
Requests to that URL are authenticated, rate limited, logged, and forwarded to the Alephium node. The response comes back exactly as the node returns it.

​
Networks

Ralph Studio supports mainnet and testnet. The network is determined by your app’s configuration when you create it.

​
Before you continue

You’ll need a Ralph Studio account to get an API key. Sign up at developer.ralphstudio.xyz, it’s free to get started. Once you’re in, create an app from the Apps page and copy your slug and API key. You’ll use those for every request.
