# Overview

Crypto Chief RPC provides production-ready node access to 79 blockchain networks from a single platform. One API key unlocks every chain — EVM L1s and rollups, Bitcoin, Solana, SUI, TON, Polkadot, NEAR, and more — through their native RPC protocols, with no proprietary wrappers or SDK lock-in.

{% hint style="info" %}
**Endpoint pattern:** `https://rpc.crypto-chief.com/{network}/{YOUR_API_KEY}`

Get your API key at [crypto-chief.com/rpc](https://crypto-chief.com/rpc/).
{% endhint %}

***

## What You Get

* **79 networks** across every major ecosystem — EVM chains (L1 + L2), Bitcoin and UTXO forks, Solana, Move VMs, TON, Substrate, and emerging protocols
* **Native interfaces** — Ethereum JSON-RPC 2.0 for EVM, Bitcoin Core RPC for UTXO, Solana JSON-RPC, Substrate RPC, REST, GraphQL, gRPC, and WebSocket as each network dictates
* **Standard library compatibility** — works out of the box with `ethers.js`, `viem`, `web3.py`, `@solana/web3.js`, Polkadot.js, and any other client that speaks the native protocol
* **Archival nodes** on select networks for full historical state queries
* **Premium tiers** with higher rate limits, dedicated throughput, and SLA guarantees

## Supported Networks

### Ethereum & EVM Layer 1

All EVM-compatible L1 chains implement the [Ethereum JSON-RPC 2.0](https://ethereum.org/en/developers/docs/apis/json-rpc/) specification. Methods are identical across networks — `eth_blockNumber`, `eth_getBalance`, `eth_call`, `eth_sendRawTransaction` — so a single integration pattern works on every chain listed here.

### EVM Layer 2 & Rollups

Optimistic rollups, ZK rollups, and Ethereum-anchored sidechains. Every network here exposes the same Ethereum JSON-RPC interface — switching from mainnet to any L2 requires only a new endpoint URL.

### Bitcoin & UTXO Networks

Bitcoin and its forks use the UTXO accounting model and the Bitcoin Core RPC interface. Bitlayer, B2 Network, and Botanix extend Bitcoin with EVM smart-contract execution anchored to Bitcoin's proof-of-work security.

Solana's native JSON-RPC interface is distinct from EVM. Sonic is an SVM-based Layer 2.

### Move-Based Networks

Move is a resource-typed smart-contract language with linear-type safety designed for secure asset management. SUI and Aptos are independent Move L1s; SUI supports three protocol interfaces simultaneously.

### TON

[TON](/chains/ton.md) (The Open Network) is a sharded proof-of-stake chain with a masterchain/workchain architecture and Bag of Cells binary encoding. Two REST interfaces are available:

| Interface                                                                                                      | Best suited for                                                                   |

## Quick Start

Every EVM endpoint accepts standard HTTP POST with a JSON-RPC 2.0 body. The example below queries the latest block number — replace the endpoint URL with any other chain from the sections above.

{% tabs %}
{% tab title="cURL" %}

```bash
curl https://rpc.crypto-chief.com/{network}/{YOUR_API_KEY} \
  -X POST \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
```

{% endtab %}

{% tab title="JavaScript" %}

```javascript
const response = await fetch("https://rpc.crypto-chief.com/{network}/{YOUR_API_KEY}", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0",
    method: "eth_blockNumber",
    params: [],
    id: 1
  })
});
const data = await response.json();
console.log(data);
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

response = requests.post(
    "https://rpc.crypto-chief.com/{network}/{YOUR_API_KEY}",
    json={
        "jsonrpc": "2.0",
        "method": "eth_blockNumber",
        "params": [],
        "id": 1
    }
)
print(response.json())
```

{% endtab %}

{% tab title="ethers.js" %}

```javascript
import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider(
  "https://rpc.crypto-chief.com/{network}/{YOUR_API_KEY}"
);
const blockNumber = await provider.getBlockNumber();
console.log(blockNumber);
```

{% endtab %}
{% endtabs %}

Each chain's documentation page lists its exact endpoint URL, supported methods, and request/response examples.
