const devKit = createDevKit({ network: 'Preprod' });
await devKit.init();
// Get Lucid instance for transactions
const lucid = devKit.getLucid();
Local Devnet
import { createDevnetManager } from 'cardano-devkit';
// Start a local devnet with fast blocks
const devnet = createDevnetManager({
blockTimeMs: 500, // 500ms blocks for rapid testing
enableOgmios: true,
enableKupo: true
});
await devnet.start();
console.log('Devnet running at:', devnet.getApiUrl());
React Integration
import { CardanoProvider, useCardano } from 'cardano-devkit';
// Wrap your app
<CardanoProvider network="Preprod" autoConnect>
<App />
</CardanoProvider>
// Use hooks anywhere
function WalletButton() {
const { isConnected, connect, address } = useCardano();
return isConnected
? <span>{address.slice(0, 20)}...</span>
: <button onClick={connect}>Connect Wallet</button>;
}
