@namespacesdk/mint-manager v1.0.13

Namespace SDK - Mint Manager

@namespacesdk/mint-manager is a TypeScript SDK for minting subnames on the ENS (Ethereum Name Service) platform. It enables seamless interaction with the Namespace ecosystem, allowing users to mint both Mainnet and Layer 2 (L2) subnames on supported networks, including Base and Optimism. The SDK abstracts the complexities of interacting with smart contracts, ensuring a smooth developer experience.

Features

• Mint Subnames: Easily mint ENS subnames listed on the Namespace platform.
• Mainnet & L2 Support: Works with Ethereum Mainnet as well as Layer 2 networks like Base and Optimism.
• Subname Availability Checks: Determine whether a subname is available for minting.
• Configurable Environment: Supports testnet mode, which uses Sepolia-listed names.
• Custom ENS Record Setting: Set resolver records at the time of minting.

Installation

npm install @namespacesdk/mint-manager

Configuration

The MintClient can be configured with the following parameters:

• isTestnet (boolean): If true, the SDK operates in test mode and uses subnames listed on the Sepolia test network instead of Mainnet.

Example Usage

import { createMintClient } from "@namespacesdk/mint-manager";

const mintClient = createMintClient({ isTestnet: true });

API

Get Minting Transaction Parameters

This method retrieves the transaction parameters required for minting a subname. It also supports setting ENS records, allowing users to pre-configure resolver records such as avatars, texts, and crypto addresses.

const txParams = await mintClient.getMintTransactionParameters({
  parentName: "example.eth",
  label: "subname",
  minterAddress: "0x123...",
  expiryInYears: 1,
  records: {
    "avatar": "https://example.com/avatar.png",
    "com.twitter": "@example",
  },
});

Response:

• abi: The ABI of the contract function to call.
• args: Arguments required for the contract call.
• functionName: The function to execute (mint).
• contractAddress: The contract handling the minting.
• account: The address executing the transaction.
• value: The total cost of minting (price + fee).

Check L1 Subname Availability

Determines if an ENS subname is available on the Ethereum Mainnet.

const isAvailable = await mintClient.isL1SubnameAvailable("subname.example.eth");
console.log(isAvailable ? "Subname is available" : "Subname is already taken");

Check L2 Subname Availability

Checks whether a subname is available on an L2 network. This requires specifying the chainId of the target network.

const isAvailable = await mintClient.isL2SubnameAvailable("subname.example.eth", 8453); // Base network
console.log(isAvailable ? "Subname is available on L2" : "Subname is already taken");

Parameters:

• subname (string): The full subname to check.
• chainId (number): The chain ID of the target L2 network (e.g., 8453 for Base, 10 for Optimism).

Get Listing for a Name

Fetches listing information for a given name from the Namespace listing API.

const listing = await mintClient.getListingForName("example.eth");
console.log("Listing Type:", listing.type);

Response:

• type: Either L1 (Mainnet) or L2 (Base, Optimism, etc.).
• l2Metadata: Additional metadata for L2 listings.
