The error is always ValueNotConservedUTxO so the amounts are not matching up somewhere

Thanks

Hi!
Do you start with 10 tokens? If you are burning all 10 of them I don’t think they should be present in the tx-out. Unless you start with 20 tokens :slight_smile:

Ah ok! Will try that, yes just start with 10 :slight_smile:

Worked a treat, many thanks Freja!

Burn NFT (minted nft) issue on transaction submit, using https://github.com/Berry-Pool/cardanocli-js.

Run this script:

const CardanocliJs = require("cardanocli-js");

const cardanocliJs = new CardanocliJs({
    network: "testnet-magic 1097911063",
    dir: __dirname + "/../",
    shelleyGenesisPath: __dirname + "/../testnet-shelley-genesis.json"
});


// 1. Get the wallet
const wallet = cardanocliJs.wallet("TGRISE");

// Define functions
const createTransaction = (tx) => {
    let raw = cardanocliJs.transactionBuildRaw(tx);
    let fee = cardanocliJs.transactionCalculateMinFee({
        ...tx,
        txBody: raw,
    });
    tx.txOut[0].value.lovelace -= fee;
    return cardanocliJs.transactionBuildRaw({ ...tx, fee });
};

const signTransaction = (wallet, tx, script) => {
    return cardanocliJs.transactionSign({
        signingKeys: [wallet.payment.skey, wallet.payment.skey],
        txBody: tx,
    });
};

// 2. Define mint script
const mintScript = {
    keyHash: cardanocliJs.addressKeyHash(wallet.name),
    type: "sig",
};

// 3. Create POLICY_ID
const POLICY_ID = cardanocliJs.transactionPolicyid(mintScript);

// 4. Define ASSET_NAME
const ASSET_NAME = "Abaidullah";

// 5. Create ASSET_ID
const ASSET_ID = POLICY_ID + "." + ASSET_NAME;

// 6. Define metadata
const metadata = {
    721: {
        [POLICY_ID]: {
            [ASSET_NAME]: {
                name: ASSET_NAME,
                image: "ipfs://QmQqzMTavQgT4f4T5v6PWBp7XNKtoPmC9jvn12WPT3gkSE",
                description: "Super Fancy Berry Space Green NFT",
                type: "image/png",
                src: "ipfs://Qmaou5UzxPmPKVVTM9GzXPrDufP55EDZCtQmpy3T64ab9N",
                // other properties of your choice
                authors: ["TGRISE"]
            }
        }
    }
}

// 7. Define transaction
const tx = {
    txIn: wallet.balance().utxo,
    txOut: [
        {
            address: wallet.paymentAddr,
            value: { ...wallet.balance().value, [ASSET_ID]: 1 },
        },
    ],
    mint: [
        { action: "burn", quantity: 1, asset: ASSET_ID, script: mintScript },
    ],
    metadata,
    witnessCount: 2,
};

// 8. Build transaction
const raw = createTransaction(tx);

// 9. Sign transaction
const signed = signTransaction(wallet, raw);
console.log(cardanocliJs.transactionView({ txFile: signed }));

// 10. Submit transaction
const txHash = cardanocliJs.transactionSubmit(signed);
console.log(assets, 'txHash:', txHash);

Gives the issue:

Can anyone help me to resolve this blocker?
