Connect to the PulseChain network without running your own infrastructure. PulseChain is an EVM-compatible Layer-1 blockchain that launched as a full fork of Ethereum, carrying over its state and running a go-ethereum / Erigon-lineage client. It is bytecode-identical to Ethereum, so standard Solidity contracts, the `eth_*` JSON-RPC surface, and tooling such as Foundry, Hardhat, Ethers.js, and Viem work without modification. The native gas token is PLS. This reference documents the Ethereum-compatible JSON-RPC interface, available over HTTP and WebSocket. ### Key Features * **Ethereum Fork**: A full Layer-1 fork of Ethereum with the same execution semantics * **EVM Identical**: Runs standard Ethereum bytecode and tooling (Foundry, Hardhat, Ethers, Viem) unchanged * **PLS Gas**: Transaction fees are paid in PLS, the network's native 18-decimal token * **EIP-1559 Fees**: Base-fee pricing with `eth_feeHistory` and priority fees, alongside legacy gas * **Full Node RPC**: The complete `eth_*` / `net_*` / `web3_*` surface plus `rpc_modules` and the `debug_*` trace namespace, over HTTP and WebSocket * **Low Fees**: Designed for inexpensive transactions relative to Ethereum mainnet {% hint style="info" %} *TECHNICAL DISCLAIMER: AUTHORITATIVE JSON-RPC API SPECIFICATION.* *GetBlock's RPC API reference documentation is provided exclusively for informational purposes and to optimize the developer experience. PulseChain implements the standard Ethereum JSON-RPC interface; the canonical specification for these methods is the Ethereum JSON-RPC specification at* [*ethereum.org*](https://ethereum.org/en/developers/docs/apis/json-rpc/)*, and PulseChain-specific behavior is documented at* [*pulsechain.com*](https://pulsechain.com/)*.* {% endhint %} ## Network Information | Property | Value | | --------------- | ---------------------------------- | | Network Name | PulseChain | | Chain ID | 369 | | Native Currency | PLS | | EVM Compatible | Yes (EVM-identical, Ethereum fork) | | Consensus | Proof-of-Stake | | Fee Model | EIP-1559 + legacy | ## Base URL {% tabs %} {% tab title="Frankfurt, Germany" %} ``` https://shared.eu-central-1.getblock.io// ``` {% endtab %} {% endtabs %} ## Supported Networks | Network | Chain ID | JSON-RPC | WSS | GraphQL | MEV protected (WebSocket) | MEV protected (JSON-RPC) | Frankfurt, Germany | New York, USA | Singapore, Singapore | | ------- | -------- | -------- | --- | ------- | ------------------------- | ------------------------ | ------------------ | ------------- | -------------------- | | Mainnet | 369 | ✅ | ✅ | ❌ | ❌ | ❌ | ✅ | ❌ | ❌ | ## Quickstart {% tabs %} {% tab title="Javascript(Axios)" %} {% stepper %} {% step %} ### Setup project ```bash mkdir pulsechain-api-quickstart && cd pulsechain-api-quickstart && npm init --yes ``` {% endstep %} {% step %} ### Install dependency ```bash npm install axios ``` {% endstep %} {% step %} ### Add code {% code title="index.js" %} ```javascript const axios = require('axios'); const url = 'https://shared.eu-central-1.getblock.io//'; const payload = { jsonrpc: '2.0', method: 'eth_blockNumber', params: [], id: 'getblock.io' }; axios.post(url, payload, { headers: { 'Content-Type': 'application/json' } }) .then(response => { console.log('Latest block:', parseInt(response.data.result, 16)); }) .catch(error => console.error(error)); ``` {% endcode %} {% endstep %} {% step %} ### Run the script ```bash node index.js ``` {% endstep %} {% step %} ### Response {% code overflow="wrap" %} ```bash Latest block: 27802561 ``` {% endcode %} {% endstep %} {% endstepper %} {% endtab %} {% tab title="Python(Request)" %} {% stepper %} {% step %} ### Setup project ```bash mkdir pulsechain-api-quickstart && cd pulsechain-api-quickstart python -m venv venv && source venv/bin/activate ``` {% endstep %} {% step %} ### Install dependency ```bash pip install requests ``` {% endstep %} {% step %} ### Add code {% code title="main.py" %} ```python import requests import json url = "https://shared.eu-central-1.getblock.io//" payload = json.dumps({ "jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": "getblock.io" }) headers = { 'Content-Type': 'application/json' } response = requests.post(url, headers=headers, data=payload) print(response.text) ``` {% endcode %} {% endstep %} {% step %} ### Run the script ```bash python main.py ``` {% endstep %} {% endstepper %} {% endtab %} {% endtabs %} ## Available API Methods ### Chain & Client Info
