KadenaNames SDK

Introduction

Welcome to the KadenaNames SDK—your gateway to seamless integration of human-readable addresses on the Kadena blockchain. Designed with convenience and ease-of-use in mind, KadenaNames empowers developers to enhance user experiences and elevate the accessibility of decentralized applications (dApps).

What is KadenaNames?

KadenaNames is a decentralized, on-chain solution that provides human-readable addresses on the Kadena blockchain. By leveraging the robust capabilities of Pact smart contracts, KadenaNames ensures a secure, tamper-proof, and user-friendly experience. Our smart contracts act as the definitive source of truth, meticulously verifying the authenticity and ownership of each name.

Why KadenaNames?

• Enhanced User Experience: Simplify interactions by replacing complex blockchain addresses with easy-to-remember names.
• Increased Accessibility: Make your dApps more approachable, attracting a broader user base.
• Security and Trust: Built on Kadena’s secure and scalable blockchain, ensuring reliability and integrity.

How Does It Work?

KadenaNames offers two primary ways to interact with human-readable names:

1. Name to Address: Convert a user-friendly name (e.g., alice.kda) into its corresponding blockchain address.
2. Address to Name: Retrieve the human-readable name associated with a specific blockchain address.
3. Fetch Sale State: Check if a name is sellable and its current price.
4. Fetch Name Info: Get detailed information about a Kadena name, including price, availability, and sale status.
5. Fetch Price By Period: Retrieve the cost of registering a name for 1 or 2 years.

These functionalities are encapsulated within the KadenaNames SDK, providing developers with straightforward methods to integrate name resolution into their applications.

Features

• TypeScript Support: Fully typed for enhanced developer experience and type safety.
• Simple Integration: Easy-to-use methods for name resolution without the need for complex configurations.
• Modular Design: Organized structure promoting maintainability and scalability.
• Error Handling: Comprehensive error logging using native console methods.
• Customization: Optional customization of Chainweb host generators to support various networks.

Installation

Install the KadenaNames SDK via npm:

pnpm add kdn-sdk

Or using yarn:

or using npm

npm install kdn-sdk

Quick Start

Here's a simple example to get you started with the KadenaNames SDK.

Import the SDK

import { kadenaNames } from 'kdn-sdk'

Convert Name to Address

async function resolveName() {
  const name = 'alice.kda'
  const networkId = 'testnet04'

  try {
    const address = await kadenaNames.nameToAddress(name, networkId)
    console.log(`Address for ${name}: ${address}`)
  } catch (error) {
    console.error(error)
  }
}

resolveName()

Convert Address to Name

async function resolveAddress() {
  const address = 'k:123456789.....abcdef'
  const networkId = 'testnet04'

  try {
    const name = await kadenaNames.addressToName(address, networkId)
    console.log(`Name for ${address}: ${name}`)
  } catch (error) {
    console.error(error)
  }
}
resolveAddress()

Fetch Sale State

async function fetchSaleState() {
  const name = 'example.kda'
  const networkId = 'testnet04'

  try {
    const saleState = await kadenaNames.fetchSaleState(name, networkId)
    console.log(`Sellable: ${saleState.sellable}, Price: ${saleState.price}`)
  } catch (error) {
    console.error(`Error fetching sale state: ${error.message}`)
  }
}

fetchSaleState()

Fetch Name Info

async function fetchNameInfo() {
  const name = 'example.kda'
  const networkId = 'testnet04'
  const owner = 'owner-address'

  try {
    const nameInfo = await kadenaNames.fetchNameInfo(name, networkId, owner)
    console.log('Name Info:', nameInfo)
  } catch (error) {
    console.error(`Error fetching name info: ${error.message}`)
  }
}

fetchNameInfo()

Fetch Price By Period

async function fetchPriceByPeriod() {
  const networkId = 'testnet04'
  const owner = 'owner-address'

  try {
    const priceForOneYear = await kadenaNames.fetchPriceByPeriod(
      1,
      networkId,
      owner
    )
    console.log(`Price for 1 year: ${priceForOneYear}`)

    const priceForTwoYears = await kadenaNames.fetchPriceByPeriod(
      2,
      networkId,
      owner
    )
    console.log(`Price for 2 years: ${priceForTwoYears}`)
  } catch (error) {
    console.error(`Error fetching price: ${error.message}`)
  }
}
