Can I build Cardano dApps without blockchain experience?

Yes. Mesh SDK is designed for JavaScript developers without blockchain backgrounds. The APIs use familiar patterns like classes, async/await, and React hooks.

What programming knowledge do I need?

Basic JavaScript or TypeScript knowledge is sufficient. If you can build a React application, you can build Cardano dApps with Mesh.

How long does it take to learn?

Most developers can build their first transaction within an hour. The wallet connection takes minutes, and the transaction builder uses intuitive method chaining.

Do I need to understand UTXOs?

No. Mesh abstracts UTXO complexity. The SDK handles UTXO selection, change outputs, and transaction balancing automatically.

For Beginners | Mesh SDK

Build Cardano dApps without blockchain expertise using Mesh SDK's beginner-friendly APIs.

Mesh SDK is designed for JavaScript developers new to Cardano. No blockchain expertise required. Use familiar patterns to build dApps in minutes.

Quick start

1. Install Mesh

npm install @meshsdk/core @meshsdk/react

2. Add wallet connection

import { MeshProvider, CardanoWallet } from "@meshsdk/react";

function App() {
  return (
    <MeshProvider>
      <CardanoWallet />
    </MeshProvider>
  );
}

3. Send your first transaction

import { useWallet } from "@meshsdk/react";
import { MeshTxBuilder } from "@meshsdk/core";

function SendADA() {
  const { wallet, connected } = useWallet();

  const sendADA = async () => {
    const utxos = await wallet.getUtxos();
    const changeAddress = await wallet.getChangeAddress();

    const txBuilder = new MeshTxBuilder();
    const unsignedTx = await txBuilder
      .txOut("addr_test1...", [{ unit: "lovelace", quantity: "5000000" }])
      .changeAddress(changeAddress)
      .selectUtxosFrom(utxos)
      .complete();

    const signedTx = await wallet.signTx(unsignedTx);
    const txHash = await wallet.submitTx(signedTx);
    console.log("Transaction:", txHash);
  };

  return (
    <button onClick={sendADA} disabled={!connected}>
      Send 5 ADA
    </button>
  );
}

Common tasks

Connect a wallet

import { CardanoWallet, useWallet } from "@meshsdk/react";

<CardanoWallet />

// Or use the hook
const { connected, wallet, connect, disconnect } = useWallet();

Build a transaction

const txBuilder = new MeshTxBuilder();
const unsignedTx = await txBuilder
  .txOut("addr...", [{ unit: "lovelace", quantity: "10000000" }])
  .changeAddress(changeAddress)
  .selectUtxosFrom(utxos)
  .complete();

Read blockchain data

import { BlockfrostProvider } from "@meshsdk/core";

const provider = new BlockfrostProvider("your-api-key");
const utxos = await provider.fetchAddressUTxOs("addr...");

Recommended learning path

Step 1: Wallet integration

import { MeshProvider, CardanoWallet, useWallet } from "@meshsdk/react";

function App() {
  return (
    <MeshProvider>
      <Header />
    </MeshProvider>
  );
}

function Header() {
  const { connected, wallet } = useWallet();

  return (
    <header>
      <CardanoWallet />
      {connected && <WalletInfo wallet={wallet} />}
    </header>
  );
}

Learn: React context, wallet state, connection handling.

Step 2: Simple transactions

async function sendPayment(wallet, recipient, amount) {
  const utxos = await wallet.getUtxos();
  const changeAddress = await wallet.getChangeAddress();

  const txBuilder = new MeshTxBuilder();
  const unsigned = await txBuilder
    .txOut(recipient, [{ unit: "lovelace", quantity: amount }])
    .changeAddress(changeAddress)
    .selectUtxosFrom(utxos)
    .complete();

  const signed = await wallet.signTx(unsigned);
  return await wallet.submitTx(signed);
}

Learn: Transaction building, signing, submission.

Step 3: Token operations

// Send existing tokens
txBuilder.txOut(recipient, [
  { unit: "policyId" + "tokenNameHex", quantity: "10" }
]);

// Mint new tokens
txBuilder
  .mint("1000", policyId, tokenNameHex)
  .mintingScript(forgingScript);

Learn: Asset structure, minting, multi-asset transactions.

Step 4: Smart contracts

import { mConStr0 } from "@meshsdk/core";

// Lock funds at script
txBuilder
  .txOut(scriptAddress, [{ unit: "lovelace", quantity: "50000000" }])
  .txOutInlineDatumValue(mConStr0([]));

// Unlock funds
txBuilder
  .spendingPlutusScriptV2()
  .txIn(utxo.input.txHash, utxo.input.outputIndex)
  .txInInlineDatumPresent()
  .txInRedeemerValue(mConStr0([]))
  .txInScript(scriptCbor);

Learn: Datums, redeemers, script addresses.

First projects

NFT gallery

import { useAssets } from "@meshsdk/react";

function NFTGallery() {
  const assets = useAssets();
  const nfts = assets?.filter(a => a.quantity === "1" && a.unit !== "lovelace");

  return (
    <div className="gallery">
      {nfts?.map(nft => (
        <NFTCard key={nft.unit} asset={nft} />
      ))}
    </div>
  );
}

Payment button

function PaymentButton({ amount, recipient }) {
  const { wallet, connected } = useWallet();

  const pay = async () => {
    const utxos = await wallet.getUtxos();
    const changeAddress = await wallet.getChangeAddress();

    const txBuilder = new MeshTxBuilder();
    const unsigned = await txBuilder
      .txOut(recipient, [{ unit: "lovelace", quantity: amount }])
      .changeAddress(changeAddress)
      .selectUtxosFrom(utxos)
      .complete();

    const signed = await wallet.signTx(unsigned);
    await wallet.submitTx(signed);
  };

  return (
    <button onClick={pay} disabled={!connected}>
      Pay {Number(amount) / 1_000_000} ADA
    </button>
  );
}

Testing

Use preprod testnet

Get test ADA from the Cardano Testnet Faucet
Switch your wallet to preprod network
Test all functionality risk-free
Move to mainnet when confident

Local development

No blockchain node required. Mesh connects to public infrastructure.

npm run dev
