v1.1.1

What's new

• Add DeServe RPC provider for Polkadot Asset Hub
  • WebSocket: wss://asset-hub.polkadot.rpc.deserve.network
  • HTTP: https://asset-hub.polkadot.rpc.deserve.network

DeServe is a global RPC network by Helikon with 14 geo-steered locations. Currently supports Polkadot Asset Hub (archive node).

npm install @zig-zag/chains@1.1.1

v1.0.0 — Complete Rebuild

@zig-zag/chains v1.0.0

Complete rebuild of the Polkadot chain registry with a merged data model, modern tooling, and comprehensive chain coverage.

What's New

20 chains with rich metadata — up from 4 in v0.2.1:

• Relay chains: Polkadot, Kusama
• Polkadot system parachains: Asset Hub, People, Coretime, Collectives, Bridge Hub
• Kusama system parachains: Asset Hub, People, Coretime, Bridge Hub
• Third-party parachains: Astar, Acala, Moonbeam, Phala, Hydration
• Testnets: Westend, Paseo, Westend Asset Hub, Paseo Asset Hub

Merged Chain Data Model

Every chain now includes:

• genesisHash — on-chain identifier (new)
• Named RPC providers (9+ per relay chain) with default key
• httpUrls — HTTP RPC endpoints (new)
• subscan — Subscan API and web URLs (new)
• signType — signing curve (sr25519, ed25519, secp256k1)
• paraId, relayChain, relay — network topology
• lightClientUrls — substrate-connect URLs
• blockExplorers — named block explorers
• network — unique slug identifier
• nativeCurrency — name, symbol, decimals
• ss58Format, testnet, ethereum flags

Build & Quality

• Migrated from Rollup to tsup (esbuild-based, CJS + ESM + DTS)
• Added vitest with 247 validation tests (schema, uniqueness, URL format)
• Fixed broken CJS/ESM exports map from v0.2.x
• Fixed acala export bug
• Organized chains into relay/, system/, parachains/, testnet/ directories
• Zero runtime dependencies, fully tree-shakeable

Installation

npm i @zig-zag/chains

Usage

import { polkadot, kusama, polkadotAssetHub } from '@zig-zag/chains';

console.log(polkadot.genesisHash);        // '0x91b171bb...'
console.log(polkadot.rpcUrls.default);     // 'wss://rpc.polkadot.io'
console.log(polkadot.rpcUrls.dwellir);     // 'wss://polkadot-rpc.n.dwellir.com'
console.log(polkadot.subscan?.api);        // 'https://polkadot.api.subscan.io'

Breaking Changes from v0.2.x

• Chain type fields renamed to camelCase (account_sign_type → signType, para_id → paraId, relay_chain → relayChain, block_explorers → blockExplorers, ss58Format replaces prefix)
• currency renamed to nativeCurrency
• rpc renamed to rpcUrls (still uses named provider keys)
• light renamed to lightClientUrls
• New required field: genesisHash
• New required field: network (was already present but now typed as required)
• Build output filenames changed (ESM: dist/index.js, CJS: dist/index.cjs)
