Quickstart

Connect and read the latest block.

import { createPublicClient, defineChain, http } from "viem";

export const zroarusDevnet = defineChain({
  id: 305583,
  name: "Zroarus Devnet",
  nativeCurrency: { name: "Zroarus Devnet Token", symbol: "tZROAR", decimals: 18 },
  rpcUrls: { default: { http: ["https://rpc.devnet.zroarus.com"], webSocket: ["wss://rpc.devnet.zroarus.com/ws"] } },
  blockExplorers: { default: { name: "Zroarus Explorer", url: "https://explorer-devnet.zroarus.com" } },
  testnet: true,
});

const client = createPublicClient({ chain: zroarusDevnet, transport: http() });
console.log(await client.getBlockNumber());

RPC Playground

Send JSON-RPC requests to the public endpoint straight from your browser.

Method

Latest block number, hex encoded.

Params (JSON array)

POST https://rpc.devnet.zroarus.com

Equivalent curl

curl -s https://rpc.devnet.zroarus.com \
  -H 'content-type: application/json' \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_blockNumber","params":[]}'

Response

Send a request to see the response.

Public endpoint limits

Enforced by the RPC gateway in front of dedicated RPC nodes. Validators are never exposed.

Methods: read and broadcast methods in the eth_, net_ and web3_ namespaces, plus qbft_getValidatorsByBlockNumber/Hash. admin_, debug_, trace_, personal_, miner_, txpool_ and engine_ are not available, nor are eth_sign and eth_sendTransaction.
Batches: at most 50 requests per batch; request bodies up to 512 KB.
Logs: eth_getLogs and eth_newFilter span at most 5,000 blocks, unless filtered by blockHash.
WebSocket subscriptions: newHeads, logs and syncing; up to 10 connections per IP and 50 messages per second per connection.

Rate limits: requests are weighted by cost (for example eth_blockNumber = 1, eth_call = 5, eth_getLogs = 10). Anonymous callers get 50 units per second and 1,000,000 units per UTC day per IP. Exceeding a limit returns JSON-RPC error -32005.
API keys: for higher limits, keys are issued on request to projects building on Zroarus. Pass a key in the path (https://rpc.devnet.zroarus.com/v1/<key>) or in the x-api-key header. Keys can be restricted to origins, IPs and methods.

Zroarus Devnet is a development network

It may be reset. Do not rely on its state for anything of value. tZROAR has no monetary value. Transactions are viewable at explorer-devnet.zroarus.com .
