Learning Curve

Overcome Cardano's learning curve with Mesh SDK's beginner-friendly TypeScript APIs.

Cardano has a steeper learning curve due to the UTXO model, native assets, and academic terminology. Mesh flattens this curve with intuitive APIs that let you build functional dApps immediately.

The challenge

UTXO mental model shift

Ethereum (Accounts)Cardano (UTXO)
Single balance numberSet of discrete outputs
Transactions modify balanceTransactions consume and create outputs
Partial spending possibleMust consume entire UTXO, create change
Sequential processingParallel transaction processing

What makes it harder

ChallengeImpact
UTXO modelDifferent from familiar account systems
Haskell rootsPlutus smart contracts use Haskell
Academic terminologyDatums, redeemers, lovelace
Fragmented docsMultiple tools and approaches

The solution

Mesh provides progressive complexity. Start simple, add advanced features as needed.

Quick start

npm install @meshsdk/core @meshsdk/react

Connect a wallet

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

function App() {
  const { connected } = useWallet();

  return (
    <MeshProvider>
      <CardanoWallet />
      {connected && <p>Wallet connected!</p>}
    </MeshProvider>
  );
}

Build a transaction

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

const txBuilder = new MeshTxBuilder({
  fetcher: provider,
  submitter: provider,
});

const unsignedTx = await txBuilder
  .txOut(recipientAddress, [{ unit: "lovelace", quantity: "5000000" }])
  .changeAddress(myAddress)
  .selectUtxosFrom(myUtxos)
  .complete();

You say "send 5 ADA to this address." Mesh handles UTXO selection, fee calculation, and change automatically.


Week 1: Wallets and transfers

TopicWhat you learn
Wallet connectionAddresses, connection state
ADA transfersTransaction lifecycle, UTXOs
Balance checkingUTXO aggregation
import { MeshCardanoBrowserWallet } from "@meshsdk/wallet";

const wallet = await MeshCardanoBrowserWallet.enable("eternl");
const address = await wallet.getChangeAddressBech32();
const utxos = await wallet.getUtxosMesh();

Week 2: Native assets

TopicWhat you learn
Token transfersAsset structure
MintingPolicy scripts
Multi-asset transactionsToken bundles
const tx = await txBuilder
  .txOut(recipient, [
    { unit: "lovelace", quantity: "2000000" },
    { unit: policyId + assetName, quantity: "10" }
  ])
  .changeAddress(changeAddress)
  .selectUtxosFrom(utxos)
  .complete();

Week 3: Metadata

TopicWhat you learn
Transaction metadataOn-chain data
NFT metadataCIP-25, CIP-68
Message standardsCIP-20
const tx = await txBuilder
  .txOut(recipient, [{ unit: "lovelace", quantity: "5000000" }])
  .metadataValue("674", { msg: ["Hello Cardano"] })
  .changeAddress(changeAddress)
  .selectUtxosFrom(utxos)
  .complete();

Week 4+: Smart contracts

TopicWhat you learn
DatumsScript state storage
RedeemersUnlock conditions
Script executionBudgets, collateral
const tx = await txBuilder
  .spendingPlutusScript("V2")
  .txIn(scriptUtxo.input.txHash, scriptUtxo.input.outputIndex)
  .txInScript(scriptCbor)
  .txInDatumValue(datum)
  .txInRedeemerValue(redeemer)
  .complete();

Key terminology

TermMeaningMesh usage
LovelaceSmallest ADA unit (1M = 1 ADA){ unit: "lovelace", quantity: "1000000" }
UTXOUnspent output - a "coin" to spendwallet.getUtxos()
DatumData attached to script outputtxInDatumValue()
RedeemerInput to unlock script outputtxInRedeemerValue()
Policy IDToken collection identifierPart of asset unit string

Why Mesh makes it easier

Familiar patterns

import { MeshCardanoHeadlessWallet, AddressType } from "@meshsdk/wallet";
import { BlockfrostProvider } from "@meshsdk/core";

// Similar to ethers.js pattern
const provider = new BlockfrostProvider("<api-key>");
const wallet = await MeshCardanoHeadlessWallet.fromMnemonic({
  networkId: 0,
  walletAddressType: AddressType.Base,
  fetcher: provider,
  mnemonic: ["your", "mnemonic", "words", "..."],
});

Pre-built React components

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

function Dashboard() {
  const { connected } = useWallet();
  const lovelace = useLovelace();

  return (
    <div>
      <CardanoWallet />
      {connected && <p>Balance: {Number(lovelace) / 1_000_000} ADA</p>}
    </div>
  );
}
