Allfeat SDK

JavaScript/TypeScript SDK for interacting with the Allfeat blockchain.

This monorepo provides essential tooling to interface with the Allfeat networks ecosystem.

📦 Packages

@allfeat/client

A high-level wrapper around dedot, preconfigured for Allfeat networks. It simplifies connection setup and interaction with Allfeat-specific runtime modules.

import { MelodieClient, AllfeatProvider } from '@allfeat/client'

const provider = new AllfeatProvider('melodie') // or 'local' | 'custom-url'
const client = await MelodieClient.new(provider)

// Query free balance
const { data: balance } = await client.query.system.account('your-address-here')

console.log(`Free balance: ${balance.free.toString()}`)

---

@allfeat/midds

Core MIDDS (Music Industry Decentralized Data Structure) definitions and utilities. This package contains types, validation logic, chain encoding helpers and client interfaces for working with musical metadata on Allfeat.

---

@allfeat/chaintypes

TypeScript bindings for the Allfeat runtime, auto-generated via dedot. These types are used internally by the client but can be imported for advanced usage or custom tooling.

import type { AllfeatMelodieApi } from '@allfeat/chaintypes'

type BalanceCall = AllfeatMelodieApi['tx']['balances']['transferKeepAlive']

---

🚀 Getting Started

pnpm install @allfeat/sdk

• local — Local development node (ws://127.0.0.1:9944)
• custom — Any valid WebSocket URL (e.g. ws://your-node:9944)

Example with custom URL:

const provider = new AllfeatProvider('ws://your-node:9944')
