Dynamic Midnight Wallet Skill

This skill generates a complete React + Vite + TypeScript app that connects Midnight wallets through Dynamic.xyz (@dynamic-labs/midnight). It replaces hand-rolled window.midnight wiring with DynamicContextProvider, DynamicWidget, and typed Midnight wallet accessors.

Primary references:

• dynamic.xyz/docs/react/wallets/using-wallets/midnight/using-midnight-wallets — injected 1AM extension
• dynamic.xyz/docs/react/wallets/using-wallets/midnight/midnight-embedded-wallets — social/email MPC wallets
• dynamic.xyz/docs/llms.txt — full Dynamic documentation index
• @dynamic-labs/midnight@4.91.2 + @dynamic-labs/sdk-react-core@4.91.2 (pin together)

Key architecture notes:

• A Midnight wallet is not a single address — it has three surfaces:

  Surface	Role	Dynamic API
  Unshielded	Public address/state	wallet.address
  Shielded	Private token pool	wallet.additionalAddresses (MidnightShielded)
  DUST	Fee-generation state	wallet.additionalAddresses (MidnightDust)

• NIGHT exists as both shielded and unshielded — different pools, not duplicate balances
• Dynamic owns connection lifecycle, connectors, address/balance accessors, send routing
• 1AM extension (injected) owns key custody, proving, signing, submission — Dynamic talks to it via @midnight-ntwrk/dapp-connector-api
• Your app owns deposit UX — surface both unshielded and shielded addresses; DUST is generated, not deposited to
• sendBalance routes by recipient prefix: mn_shield... → shielded pool, otherwise unshielded. No cross-pool transfers
• Always guard with isMidnightWallet(wallet) before calling Midnight methods

Relationship to other skills:

• Raw DApp Connector without Dynamic → react-wallet-connector/
• Contract deploy + circuit calls via 1AM directly → 1am-wallet/
• Embedded wallets only → see §17 in this skill (DynamicWaasMidnightConnectors)

    unshieldedAddress: primaryWallet.address,
    shieldedAddress,
    dustAddress,
  };
}

---

11) src/MidnightWalletPanel.tsx

Displays all three surfaces and balances. No CSS — add Tailwind or your preferred styling.

import { useCallback, useEffect, useState } from 'react';
import { useMidnightWallet } from './hooks/useMidnightWallet';

type Balances = {
  shieldedBalance?: string;
  unshieldedBalance?: string;
  dustBalance?: { balance: string; cap: string };
};

export default function MidnightWalletPanel() {
  const { wallet, isConnected, unshieldedAddress, shieldedAddress, dustAddress } =
    useMidnightWallet();
  const [balances, setBalances] = useState<Balances | null>(null);
  const [error, setError] = useState<string | null>(null);
  const [loading, setLoading] = useState(false);

  const refreshBalances = useCallback(async () => {
    if (!wallet) return;
    setLoading(true);
    setError(null);
    try {
      const formatted = await wallet.getFormattedBalances();
      setBalances({
        shieldedBalance: formatted.shieldedBalance,
        unshieldedBalance: formatted.unshieldedBalance,
        dustBalance: formatted.dustBalance,
      });
    } catch (e) {
      setError(String(e));
    } finally {
      setLoading(false);
    }
  }, [wallet]);

  useEffect(() => {
    void refreshBalances();
  }, [refreshBalances]);

  if (!isConnected || !wallet) {
    return <p>Connect your Midnight wallet with the widget above.</p>;
  }

  return (
    <div>
      <h2>Wallet Surfaces</h2>
      <dl>
        <dt>Unshielded (public)</dt>
        <dd title={unshieldedAddress}>{unshieldedAddress}</dd>
        <dt>Shielded (private)</dt>
        <dd title={shieldedAddress ?? ''}>{shieldedAddress ?? '—'}</dd>
        <dt>DUST (fees)</dt>
        <dd title={dustAddress ?? ''}>{dustAddress ?? '—'}</dd>
      </dl>

      <h2>Balances</h2>
      {loading ? <p>Loading…</p> : null}
      {error ? <p role="alert">{error}</p> : null}
      {balances ? (
        <ul>
          <li>Unshielded NIGHT: {balances.unshieldedBalance ?? '0'}</li>
          <li>Shielded NIGHT: {balances.shieldedBalance ?? '0'}</li>
          <li>
            DUST:{' '}
            {balances.dustBalance
              ? `${balances.dustBalance.balance} / cap ${balances.dustBalance.cap}`
              : '—'}
          </li>
        </ul>
      ) : null}
      <button type="button" onClick={() => void refreshBalances()}>
        Refresh Balances
      </button>

      <h2>Deposit instructions</h2>
      <p>
        Send to the <strong>unshielded</strong> address for public NIGHT, or the{' '}
        <strong>shielded</strong> address for private NIGHT. DUST is generated from
        registered unshielded NIGHT — it is not deposited to directly.
      </p>
    </div>
  );
}

---

14) Run

cp .env.example .env
# Paste your Dynamic Environment ID
npm install
npm run dev

Open http://localhost:5173. Click DynamicWidget → connect 1AM wallet → panel shows three surfaces and balances.

---

15) Checking Wallet Type

import { isMidnightWallet } from '@dynamic-labs/midnight';

if (!isMidnightWallet(wallet)) {
  throw new Error('This wallet is not a Midnight wallet');
}

Always narrow before calling getFormattedBalances(), sendBalance(), or connector methods.

---

16) Richer Shielded Handles (Connector API)

When circuits need coin/encryption public keys:

const connector = primaryWallet.connector;

const { shieldedAddress, shieldedCoinPublicKey, shieldedEncryptionPublicKey } =
  await connector.getShieldedAddresses();
const { unshieldedAddress } = await connector.getUnshieldedAddress();
const { dustAddress } = await connector.getDustAddress();

Use these when wiring 1am-wallet/ provider sessions on top of Dynamic.

---

17) Embedded Wallets (Social / Email)

Swap connector in App.tsx:

import { DynamicWaasMidnightConnectors } from '@dynamic-labs/midnight';

<DynamicContextProvider
  settings={{
    environmentId,
    walletConnectors: [DynamicWaasMidnightConnectors],
  }}
>

Dashboard requirements:

1. Enable Midnight under Chains & Networks
2. Enable Private Key Exports under Embedded Wallets → Security (403 on all ops if disabled)

Embedded balance shape differs slightly:

const { unshieldedBalance, shieldedTokenCount, dustBalance, dustSyncing } =
  await primaryWallet.getFormattedBalances();

// Poll until DUST sync completes (WaaS only)
if (dustSyncing) {
  setTimeout(() => void refreshBalances(), 2500);
}

Embedded-only extras: registerDust(), signMessage(), step-by-step createTransferTransaction → signTransaction → submitTransaction.

---

18) Sending Tokens

// Routes by recipient prefix — mn_shield... = shielded, else unshielded
await primaryWallet.sendBalance({
  toAddress: 'mn_shield...',
  amount: '1.5', // human-readable NIGHT for extension wallets
});

Cross-pool transfers are not supported. Sender and recipient must be in the same pool.

For raw per-token amounts:

const { shielded, unshielded, dust } = await primaryWallet.getBalances();

---

19) Ownership Boundaries

Layer	Owns
Dynamic	Connection lifecycle, connectors, MidnightWallet object, address/balance accessors, send routing
1AM extension	Key custody, derivation, ZK proving, signing, submission
Your DApp	Deposit/receive UX (show unshielded and shielded), which pool to display, DUST generation messaging

---

20) Troubleshooting

Symptom	Cause	Fix
Midnight not in widget	Chain disabled	Enable Midnight in Dynamic dashboard → Chains & Networks
403 on all wallet methods (embedded)	Private Key Exports off	Enable under Embedded Wallets → Security
isMidnightWallet false	Wrong connector or chain	Use MidnightWalletConnectors or DynamicWaasMidnightConnectors
Shielded address missing	Wallet still syncing	Retry after connect; poll dustSyncing for WaaS
Send fails cross-pool	mn_addr → mn_shield	Same pool only — unshielded to unshielded, shielded to shielded
Version mismatch errors	Mixed @dynamic-labs/* versions	Pin all Dynamic packages to same version
Empty DUST	NIGHT not registered	Call registerDust() after funding unshielded NIGHT (embedded)

---

21) Agent Checklist

When generating this template for a user:

• Scaffold Vite react-ts or write all files from this skill
• Install @dynamic-labs/sdk-react-core, @dynamic-labs/midnight, @dynamic-labs/sdk-api-core at same version
• Set VITE_DYNAMIC_ENVIRONMENT_ID in .env
• Use MidnightWalletConnectors for extension (default) or DynamicWaasMidnightConnectors for embedded
• Include DynamicWidget for connect/disconnect
• Surface unshielded, shielded, and DUST in deposit UI
• Guard all Midnight calls with isMidnightWallet
• Omit CSS unless user requests styling
• Link to 1am-wallet/ if user needs contract deploy on top of Dynamic connection
