ZetaChain RPC Endpoint

Fast, flat-rate ZetaChain RPC node provider — free tier, no KYC, HTTP & WebSocket.

ZetaChain is a Cosmos-SDK Layer 1 with an EVM (ZetaEVM) designed for omnichain smart contracts that can read from and write to connected chains, including non-smart-contract chains like Bitcoin, without wrapped assets. SwiftNodes provides ZetaChain mainnet RPC over HTTP and WebSocket.

About ZetaChain

ZetaChain launched its mainnet on February 1, 2024. It runs on CometBFT (Tendermint) consensus with validators voting in proportion to staked ZETA, giving roughly 5-second block times and instant, non-reversible finality.

ZetaChain's defining feature is cross-chain interoperability managed by a distributed TSS (threshold signature scheme) validator set, allowing contracts to control native assets on external chains rather than relying on centralized bridges. Developers deploy standard Solidity contracts on the EVM and use Hardhat, Foundry, and ethers.js.

Common Use Cases on ZetaChain

• Omnichain smart contracts
• Native Bitcoin DeFi without wrapped BTC
• Cross-chain swaps and messaging
• Bridgeless asset transfers
• Multi-chain liquidity routing

ZetaChain Ecosystem

Hosts omnichain applications and integrations including ZetaSwap, and works with cross-chain tooling; the network connects to Ethereum, BNB Chain, Polygon, and Bitcoin.

Quick Start: Connect to ZetaChain

cURL

curl -X POST https://rpc.swiftnodes.io/rpc/zetachain?key=YOUR_API_KEY \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'

ethers.js

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider(
  "https://rpc.swiftnodes.io/rpc/zetachain?key=YOUR_API_KEY"
);

const blockNumber = await provider.getBlockNumber();
console.log("ZetaChain block:", blockNumber);

viem

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/zetachain?key=YOUR_API_KEY"),
});

const blockNumber = await client.getBlockNumber();

web3.py

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://rpc.swiftnodes.io/rpc/zetachain?key=YOUR_API_KEY"))
print("ZetaChain block:", w3.eth.block_number)

Bridging to ZetaChain

ZetaChain's protocol-level TSS handles native deposits and withdrawals to connected chains; assets move in and out without third-party wrapped-token bridges.
