runelib

runelib

runelib is a typeScript lib for enciphering and deciphering runestones.

Deciphering

const mintRawTx = '02000000000101dc58870c48618a937cda4ea238587e17413dde50f8fb8de0e87144acea817bbb0100000000fdffffff030000000000000000086a5d0514d301140110270000000000002251207817a206d8fc43fe54a61a94dd4ff01ec7286826cf44526a59265bf9d3909c66f39b052a01000000225120675fad4019ca08cdc3cf8678af6faa6686b719389a930b0fa13c4ecf9ea7d08b0140f775e5e75ac8ed4d1556779525da619851a95d8328a78382c1c719cf28c76eaf550551643b9e92feba132f75595992d34babe1193ecfad03eb5d830b42da10c100000000'

const stone = Runestone.decipher(mintRawTx);

Enciphering

const block = 2586233;
const txIndex = 1009;
const mintstone = new Runestone([], none(), some(new RuneId(block, txIndex)), some(1));

const buffer = mintstone.encipher();

Minting

Example code that minting UNCOMMON•GOODS

async function mint() {


    const mintstone = new Runestone([], none(), some(new RuneId(1, 0)), some(1));


    const keyPair = ECPair.fromWIF(
        yourKey,
        network
    );

    const { address, } = payments.p2wpkh({ pubkey: keyPair.publicKey, network })

    console.log('address:', address)

    const utxos = await waitUntilUTXO(address as string)
    console.log(`Using UTXO ${utxos[0].txid}:${utxos[0].vout}`);

    const psbt = new Psbt({ network });
    psbt.addInput({
        hash: utxos[0].txid,
        index: utxos[0].vout,
        witnessUtxo: { value: utxos[0].value, script: Address.toOutputScript(address as string, network) },
    });

    psbt.addOutput({
        script: mintstone.encipher(),
        value: 0
    });

    psbt.addOutput({
        address: ord_address, // ord address
        value: 10000
    });

    const fee = 5000;

    const change = utxos[0].value - fee - 10000;

    psbt.addOutput({
        address: change_address, // change address
        value: change
    });

    await signAndSend(keyPair, psbt, address as string);
    
}

Etching
