AI-assisted Cardano wallet integration using @meshsdk/wallet.
npm install @meshsdk/wallet
# or
npm install @meshsdk/core # includes wallet + transaction + provider
| Type | Class | Use Case |
|---|---|---|
| Browser | MeshCardanoBrowserWallet | Web apps - connect to Eternl, Nami, Flint, etc. |
| Headless | MeshCardanoHeadlessWallet | Server-side, CLI, backend - from mnemonic/keys |
import { MeshCardanoBrowserWallet } from '@meshsdk/wallet';
// List installed wallets
const wallets = MeshCardanoBrowserWallet.getInstalledWallets();
// → [{ id: 'eternl', name: 'Eternl', icon: '...', version: '...' }, ...]
// Connect to wallet
const wallet = await MeshCardanoBrowserWallet.enable('eternl');
// Get addresses (Bech32)
const addresses = await wallet.getUsedAddressesBech32();
const changeAddr = await wallet.getChangeAddressBech32();
const stakeAddrs = await wallet.getRewardAddressesBech32();
// Get UTxOs and balance (Mesh format)
const utxos = await wallet.getUtxosMesh();
const balance = await wallet.getBalanceMesh();
const collateral = await wallet.getCollateralMesh();
// Sign and submit
const signedTx = await wallet.signTxReturnFullTx(unsignedTxHex);
const txHash = await wallet.submitTx(signedTx);
// Sign data (CIP-8)
const signature = await wallet.signData(address, 'Hello Cardano!');
import { MeshCardanoHeadlessWallet } from '@meshsdk/wallet';
import { BlockfrostProvider } from '@meshsdk/core';
const provider = new BlockfrostProvider('your-api-key');
// From mnemonic
const wallet = await MeshCardanoHeadlessWallet.fromMnemonic({
mnemonic: ['word1', 'word2', ...], // 24 words
networkId: 0, // 0 = testnet, 1 = mainnet
walletAddressType: 'Base', // 'Base' or 'Enterprise'
fetcher: provider,
submitter: provider,
});
// Same API as browser wallet
const address = await wallet.getChangeAddressBech32();
const utxos = await wallet.getUtxosMesh();
const signedTx = await wallet.signTxReturnFullTx(unsignedTxHex);
