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

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)

This script allows you to create a recursive ordinal inscription on the Bitcoin testnet using Taproot addresses. It involves creating an HTML content, enciphering it as a Taproot script, and broadcasting the transaction to the testnet network.

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.

4. Broadcast Transaction: The signAndSend function handles the signing and broadcasting of the transaction. It supports both node environment and browser environment.

• etching(): Main function to create the recursive ordinal inscription.
• waitUntilUTXO(address: string): Polls the address for UTXOs until found.
• getTx(id: string): Fetches transaction hex by ID.
• signAndSend(keyPair: BTCSigner, psbt: Psbt, address: string): Signs and broadcasts the PSBT.
• broadcast(txHex: string): Broadcasts the raw transaction to the network.
• tapTweakHash(pubKey: Buffer, h: Buffer | undefined): Computes the Taproot tweak hash.
• toXOnly(pubkey: Buffer): Converts a public key to X-only format.
• tweakSigner(signer: BTCSigner, opts: any): Tweaks the signer for Taproot key tweaking.

This script enables the minting of Runes using Taproot addresses on the Bitcoin testnet. It leverages bitcoinjs-lib, ecpair, and runelib to create, sign, and broadcast a Bitcoin transaction containing Runes.

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. Minting with Taproot: The mintWithTaproot function is the main function that mints Runes. It involves the following steps:

   • Define Runes to be minted.
   • Create a Runestone with the specified Runes.
   • Tweak the signer for Taproot key tweaking.
   • Generate a Taproot address.
   • 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.

4. Broadcast Transaction: The signAndSend function handles the signing and broadcasting of the transaction. It supports both node environment and browser environment.

• mintWithTaproot(): Main function to mint Runes using Taproot.
• waitUntilUTXO(address: string): Polls the address for UTXOs until found.
• getTx(id: string): Fetches transaction hex by ID.
• signAndSend(keyPair: BTCSigner, psbt: Psbt, address: string): Signs and broadcasts the PSBT.
• broadcast(txHex: string): Broadcasts the raw transaction to the network.
• tapTweakHash(pubKey: Buffer, h: Buffer | undefined): Computes the Taproot tweak hash.
• toXOnly(pubkey: Buffer): Converts a public key to X-only format.
• tweakSigner(signer: BTCSigner, opts: any): Tweaks the signer for Taproot key tweaking.

This script allows you to mint recursive Runes on the Bitcoin testnet using Taproot addresses. The script uses bitcoinjs-lib, ecpair, and runelib libraries to create, sign, and broadcast Bitcoin transactions containing Runes.

Make sure you have the following dependencies installed:

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

You can install them using npm:

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

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 Taproot Inscription: The createChildInscriptionTapScript function creates the Taproot script for the inscription, using the provided content and metadata.

4. Mint Runes and Create PSBT: The childInscribe function mints Runes and creates a Partially Signed Bitcoin Transaction (PSBT). It includes:

   • Funding the Taproot address.
   • Adding inputs and outputs to the PSBT.
   • Signing and broadcasting the transaction.

5. Broadcast Transaction: The signAndSend function handles the signing and broadcasting of the transaction.

• contentBuffer(content: string): Converts content string to a buffer.
• createChildInscriptionTapScript(): Creates the Taproot script for child inscriptions.
• childInscribe(): Main function to mint Runes using Taproot.
• signAndSend(keyPair: BTCSigner, psbt: Psbt): Signs and broadcasts the PSBT.
• waitUntilUTXO(address: string): Polls the address for UTXOs until found.
• getTx(id: string): Fetches transaction hex by ID.
• broadcast(txHex: string): Broadcasts the raw transaction to the network.
• tapTweakHash(pubKey: Buffer, h: Buffer | undefined): Computes the Taproot tweak hash.
• toXOnly(pubkey: Buffer): Converts a public key to X-only format.
• tweakSigner(signer: BTCSigner, opts: any): Tweaks the signer for Taproot key tweaking.

• network: Configured to use Bitcoin testnet.
• txhash: Transaction hash of the parent inscription.
• memeType: MIME type for the content.
• metaProtocol: Meta protocol buffer.
• receiveAddress: Address to receive the Runes.
• metadata: Metadata for the inscription.
• fee: Transaction fee.
• parentInscriptionTXID: Transaction ID of the parent inscription.
• contentBufferData: Buffer containing the content for the inscription.
• revealtxIDBuffer: Buffer of the parent inscription transaction ID.
• pointerBuffer: Array of buffers for pointers in the Taproot script.
• metadataBuffer: CBOR encoded metadata buffer.
• contentBufferArray: Array of content buffers split into chunks.

The script will output logs at various stages:

• The Taproot address where funds should be sent.
• The UTXO being used.
• The raw transaction hex to be broadcasted.
• The transaction ID after broadcasting.

• The script is configured to work with the Bitcoin testnet.
• Ensure that you have testnet coins available in the provided private key.
• Adjust the fee and other parameters as needed.
