Rune Launchpad(Users can claim rune tokens)

Prerequisites

---

Before running the script, ensure you have the following dependencies installed:

• bitcoinjs-lib
• ecpair
• @bitcoinerlab/secp256k1
• axios
• runelib
• cbor

You can install them using npm:

npm install bitcoinjs-lib ecpair @bitcoinerlab/secp256k1 axios runelib

Configuration

---

Ensure you have a .env file in your project root with the following variables:

PRIVATE_KEY=<your_private_key>
MNEMONIC=<your_seed_mnemonic> (optional, if using SeedWallet)

Usage

1. Initialize ECC Library: The script initializes the ECC library using initEccLib from bitcoinjs-lib.

2. Wallet Setup: The script supports two types of wallets: SeedWallet and WIFWallet. Currently, the WIFWallet is used.

3. Create Etching: The etching function is the main function that creates the recursive ordinal. It involves the following steps:

   • Define the HTML content to be inscribed.
   • Create an inscription object using EtchInscription.
   • Define a Taproot script with the inscription and the wallet's public key.
   • Generate a Taproot address and wait for UTXOs to be funded to this address.
   • Create a Partially Signed Bitcoin Transaction (PSBT).
   • Add inputs and outputs to the PSBT.
   • Sign and broadcast the transaction.
