Immutable zkEVM RPC Endpoint

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

Immutable zkEVM is a gaming-focused Ethereum Layer 2 built with the Polygon CDK, using IMX for gas to provide low fees for Web3 games. SwiftNodes provides Immutable zkEVM mainnet RPC over HTTP and WebSocket.

Network: Immutable zkEVM
Type: EVM
Chain ID: 13371
Slug: immutable-zkevm
Native token: IMX (Immutable)

About Immutable zkEVM

Immutable zkEVM's mainnet opened in early access for select game studios in early 2024 before broader availability. It is a zero-knowledge rollup that settles to Ethereum and uses Polygon CDK technology.

The chain targets blockchain games with low transaction fees and block times around 2 seconds. IMX is the native gas token, and developers use standard Solidity contracts plus Immutable's gaming-oriented SDKs and APIs for minting, orders, and wallets.

Common Use Cases on Immutable zkEVM

  • Web3 game asset minting
  • In-game NFT economies
  • Gaming marketplaces and orderbooks
  • Low-fee microtransactions
  • Studio token launches
