@dedot/chain-specs

A collection of well-known chain specifications for connecting to Polkadot, Kusama, and testnet networks using Dedot with the Smoldot light client.

This package provides optimized chain specs with full ESM and CommonJS support via subpath exports, allowing you to import individual network specifications on-demand.

This package is a fork of @substrate/connect-known-chains with customizations!

Installation

# npm
npm install @dedot/chain-specs

# yarn
yarn add @dedot/chain-specs

# pnpm
pnpm add @dedot/chain-specs

Usage

Basic Usage

Import chain specs and use them with Dedot and Smoldot:

import { DedotClient, SmoldotProvider } from 'dedot';
import { start } from 'dedot/smoldot';
import { chainSpec } from '@dedot/chain-specs/polkadot';

const smoldot = start();
const chain = await smoldot.addChain({ chainSpec });
const provider = new SmoldotProvider(chain);
const client = await DedotClient.new(provider);

Importing Multiple Networks

// Import specific networks
import { chainSpec as polkadot } from '@dedot/chain-specs/polkadot';
import { chainSpec as kusama } from '@dedot/chain-specs/ksmcc3';
import { chainSpec as assetHub } from '@dedot/chain-specs/polkadot_asset_hub';

// Or import all at once
import { polkadot, ksmcc3, polkadot_asset_hub } from '@dedot/chain-specs';
