ShadowLine — Confidential Tokens, Made Simple

The Portfolio shows everything you hold across the registry and lets you reveal every confidential balance with a single signature.

Batch decryption

Decrypting balances one-by-one would prompt your wallet once per token. Instead, the portfolio uses useConfidentialBalances to cover many wrappers under a single EIP-712 permit — one click, one signature, every official balance revealed.

decrypt-all.tsx

import { useConfidentialBalances } from '@zama-fhe/react-sdk';
import { formatUnits } from 'viem';
import { useState } from 'react';

function DecryptAll({ wrappers }: { wrappers: `0x${string}`[] }) {
  const [decryptRequested, setDecryptRequested] = useState(false);

  const { data: balances } = useConfidentialBalances({
    tokenAddresses: wrappers,
    enabled: decryptRequested,   // one permit covers all
  });

  if (!decryptRequested) {
    return <button onClick={() => setDecryptRequested(true)}>Decrypt All</button>;
  }
  return (
    <ul>
      {wrappers.map((w) => (
        <li key={w}>{formatUnits(balances?.[w.toLowerCase()] ?? 0n, 6)}</li>
      ))}
    </ul>
  );
}

Three kinds of holdings

Official wrappers — verified registry pairs, batch-decrypted together.
Custom wrappers — your locally-added pairs that support shield/unshield.
Custom decrypt-only — confidential tokens with no ERC-20 underlying; each card runs its own per-row decrypt.

Session reset:the wallet menu's "Reset Decryption Session" wipes cached FHE permits app-wide. The next decrypt then prompts for a fresh wallet signature — useful if you switch accounts or want to re-arm every gate at once.
