Connext

Connext is a modular, open-source infrastructure stack for trust-minimized communication between blockchains. Its TypeScript monorepo includes an SDK for integrations, cross-chain messaging and liquidity components, chain indexing, transaction routing, deployment code and illustrative examples.

Practical overview

When it fits

Use Connext when developing cross-chain applications or investigating modular infrastructure for blockchain messaging and its supporting operations. Check the project documentation for network-specific integration details.

Who it is for

  • Developers integrating cross-chain communication into applications.
  • Teams exploring infrastructure components for messaging, routing, liquidity or chain data indexing.

Documented uses

  • Integrate Connext contract calls into a cross-chain application using its JavaScript SDK.
  • Build and work with components for message execution, verification, transport and liquidity.
  • Index chain data and query raw or computed results through Cartographer.
  • Develop or operate a router that listens for messaging and subgraph events and dispatches transactions.
Before you choose

Requirements & limits

The repository is public and lists an MIT license. Local development prerequisites documented in the README are Node.js 18.x, Yarn Berry and Docker; RabbitMQ and Redis are used as development containers.

  • The architecture divides application, liquidity, execution, verification and transport responsibilities across components.
  • The JavaScript SDK is described as a wrapper around contract calls for integrations.
  • The monorepo documents local development setup, package builds, tests and router hot-reload mode.
  • Network support is not specified in the provided project description; consult the project documentation for integration planning.

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

Prepare the Connext development environment

Install dependencies, build the monorepo and start its documented local service containers.

Before you start

  • Node.js 18.x
  • Latest Yarn version, set to Berry
  • Docker

Steps

  1. Set Yarn to Berry with yarn set version berry.

  2. Install dependencies and build all packages with yarn && yarn build:all.

  3. Start RabbitMQ with the management plugin using the README's Docker command.

  4. Start Redis using the README's Docker command.

Expected outcome

The README describes this as preparing the environment to interact with the monorepo, with dependencies built and RabbitMQ and Redis running in containers.

Guide limitations

  • This covers local development setup, not deploying Connext or completing a cross-chain transaction.
  • The repository instructions do not specify supported blockchain networks or deployment environments.
