Nitrolite

Nitrolite is an open-source state-channel framework for prototyping applications on Ethereum and other EVM-compatible blockchains. It combines Solidity contracts for channel operations, Nitronode for message brokering and off-chain state management, Go and TypeScript SDKs, and Cerebro, a REPL for interacting with Nitronode.

Practical overview

When it fits

Use Nitrolite when developing a prototype that needs state-channel concepts such as funded channels, signed off-chain updates, checkpoints, or channel closure.

Who it is for

  • Developers prototyping applications that use state channels.
  • Backend and CLI developers looking for a Go SDK.
  • Web and mobile developers looking for a TypeScript SDK.

Documented uses

  • Prototype application workflows using off-chain state updates between channel participants.
  • Build backend, CLI, web, or mobile clients with the Go or TypeScript SDK.
  • Manage channel interactions through Cerebro and Nitronode.
Before you choose

Requirements & limits

The repository is public, open source, and licensed under MIT.

  • The framework documents Ethereum and other EVM-compatible chains; Nitronode names Polygon, Celo, and Base as supported connections.
  • Nitronode lists SQLite and PostgreSQL storage options.
  • Go and TypeScript SDKs serve different client-development contexts.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install a Nitrolite SDK

Add the Go or TypeScript SDK to a project for state-channel application development.

Before you start

  • A Go project to use the Go SDK, or a Node.js project to use the TypeScript SDK.

Steps

  1. For Go, run the command below.

    Documented command
    go get github.com/layer-3/nitrolite/sdk/go

  2. For TypeScript, run the command below.

    Documented command
    npm install @layer-3/nitrolite

Expected outcome

The selected Nitrolite SDK is added to the project’s dependencies.

Guide limitations

  • The README gives installation commands but does not provide an application implementation walkthrough.
