segregated witness – Easy methods to create a litecoin testnet segwit pockets offline

Hello So I’m utilizing the bitcoinjs-lib pacakge to generate pockets deal with and personal keys domestically nevertheless it looks as if it is creating the litecoin deal with of legacy kind, my aim is right here to create of segwit kind which has a prefix like tltc

right here is my code:

const bitcoin = require('bitcoinjs-lib');

perform generateLtcAddress() {
    const litecoinTestnet = {
        messagePrefix: 'x19Litecoin Signed Message:n',
        bip32: {
            public: 0x043587cf,
            non-public: 0x04358394
        },
        pubKeyHash: 0x6f,
        scriptHash: 0xc4, //  for segwit (begin with 2)
        wif: 0xef
    };

    const keyPair = bitcoin.ECPair.makeRandom({ community: litecoinTestnet });
    const { deal with } = bitcoin.funds.p2pkh({
        pubkey: keyPair.publicKey,
        community: litecoinTestnet
    });

    const privateKeyWIF = keyPair.toWIF();

    console.log("Litecoin Testnet Handle:", deal with);
    console.log("Personal Key (WIF):", privateKeyWIF);
    return {
        deal with: deal with,
        privateKey: privateKeyWIF
    };
}

Output:

Litecoin Testnet Handle: mnUDkLibVp1MhKSm6pvYgT26PUxeTjHJiR
