Why a Read‑Only Connection Matters <a name="why-a-read-only-connection-matters"></a>

A read‑only connection allows a software application to query public blockchain data associated with your addresses without ever receiving the private keys needed to spend funds.

Zero exposure of signing capability. The hardware wallet signs no transaction when it is in read‑only mode; the device simply confirms that the address belongs to you.
Preservation of cold storage integrity. Cold storage is defined by the absence of network exposure. A read‑only link maintains that principle because the connection is unidirectional.
Regulatory compliance. For institutional investors, auditors often require evidence that no signing capability was granted to third‑party software.

Statistically, a survey of 2,400 crypto investors conducted in early 2026 found that 71 % of respondents who used a hardware wallet also employed a portfolio tracker, citing transparency and tax reporting as primary motivations.

Choosing a Portfolio Tracker That Supports Hardware Wallets <a name="choosing-a-portfolio-tracker"></a>

When evaluating a portfolio tracker, focus on three pillars: compatibility, data fidelity, and security.

|---------|------------------------|------------------------|------------------|

Key selection criteria

1. Native SDKs for hardware wallets – Applications that integrate the official Ledger SDK or Trezor Bridge reduce the need for third‑party adapters.

2. Read‑only mode enforcement – The tracker must explicitly state that it operates in “view‑only” when a hardware wallet is connected.

3. Open‑source verification – Open source clients enable community audits of the code that handles address extraction.

For the remainder of this guide, we will use Delta as a reference application because its interface is representative of industry best practices, but the steps are virtually identical for other trackers that support the same SDKs.

Step‑by‑Step: Linking a Ledger Device <a name="ledger-connection"></a>

1. Prepare Your Ledger

Update firmware. Connect the Ledger to the Ledger Live desktop client, navigate to Settings → Firmware, and install the latest release. Firmware updates address security patches and add support for newer blockchain networks.
Enable the appropriate app(s). Open Ledger Live, select Manager, and install the individual crypto apps you intend to track (e.g., Bitcoin, Ethereum, Binance Smart Chain).

2. Install the Ledger Bridge (Windows/macOS)

Download the latest bridge from the official Ledger website. The bridge establishes a local WebUSB/WebHID channel that portfolio apps use to read addresses.
Run the installer with administrative rights. The bridge will appear as a background service titled “Ledger Bridge Service.”

3. Launch Your Portfolio Tracker

Open the app (e.g., Delta) on your desktop or mobile device.
Navigate to “Add Wallet” → “Hardware Wallet.” The UI will prompt you to select the device type; choose Ledger.

4. Connect the Ledger in Read‑Only Mode

Plug the Ledger into a USB port and unlock it with your PIN.
Open the specific crypto app (e.g., Ethereum) on the device. The screen should display the Ledger logo and the name of the selected blockchain.

Important: Do not approve any transaction signing request. The tracker will request a public address only.

5. Authorize Address Retrieval

The tracker will display a pop‑up asking you to “Allow read‑only access to the selected address?”
Press both buttons simultaneously on the Ledger to confirm. This action generates a public key derivation path (e.g., m/44'/60'/0'/0/0) without exposing the private key.

6. Verify and Save

The portfolio app shows the derived address and the current on‑chain balance. Verify that the balance matches the one shown on a block explorer (e.g., Etherscan).
Click “Save.” The address is now stored in the tracker’s database, and subsequent balance updates will occur automatically.

7. Enable Multi‑Address Tracking (Optional)

For a comprehensive view, repeat steps 4‑6 for each derivation path you use (e.g., m/44'/60'/0'/0/1 for the second Ethereum address).
Most trackers support HD‑wallet scanning for the first 20 addresses by default.

Step‑by‑Step: Linking a Trezor Device <a name="trezor-connection"></a>

1. Firmware and App Setup

Update to the latest Trezor firmware using the Trezor Suite desktop application. Firmware updates are released quarterly and often include compatibility fixes for emerging tokens.
Enable the appropriate coin(s) in Trezor Suite. For Ethereum‑based assets, toggle the “Ethereum” switch.

2. Install the Trezor Bridge (if required)

For browsers that do not natively support WebUSB, download the Trezor Bridge from the official website. The bridge works as a local proxy, translating USB signals into a format the tracker can read.

3. Open Your Portfolio Tracker

In the tracker’s menu, choose Add Wallet → Hardware Wallet → Trezor.

4. Connect the Trezor in Read‑Only Mode

Plug the device into a USB port and unlock it with your PIN.
On the Trezor screen, select the “Ethereum (or BTC, etc.)” app.

5. Authorize Public Key Export

The tracker asks for permission to “Export public address for monitoring only.”
Confirm by tapping the right button on the Trezor. The left button declines; do not press it.

6. Confirm Address Accuracy

The displayed address should match the one shown on Trezor Suite under Accounts.
If you manage multiple accounts, repeat step 4 for each account index you wish to monitor.

7. Complete the Integration

Press “Add” in the tracker. From this point forward, the portfolio app polls the blockchain at the interval you selected during setup (commonly 1‑minute for real‑time tracking).

Connecting Other Hardware Wallets (KeepKey, BitBox02, Coldcard) <a name="other-hardware-wallets"></a>

| Device | Required Bridge | Typical Integration Steps |

|--------|----------------|---------------------------|

| KeepKey | None (native WebUSB) | 1️⃣ Open KeepKey, select the target coin. 2️⃣ In the portfolio app, choose “KeepKey.” 3️⃣ Confirm the read‑only request on the device. |

| BitBox02 | BitBox02 Bridge (macOS/Windows) | 1️⃣ Install the bridge. 2️⃣ Open BitBox02, unlock with passphrase. 3️⃣ Approve public key retrieval via the device’s two‑button interface. |

| Coldcard | Coldcard USB (compatible with Ledger Bridge) | 1️⃣ Insert the microSD card with a pre‑generated xpub file. 2️⃣ Import the xpub into the tracker manually. 3️⃣ No USB connection required; the workflow is purely offline. |

General workflow for any hardware wallet

1. Update the device firmware to the latest stable version.

2. Install any required bridge software from the manufacturer’s website.

3. Launch the portfolio tracker and select the hardware device type.

4. Unlock the device and navigate to the relevant coin application.

5. Approve the read‑only request using the device’s physical buttons.

6. Verify the displayed address against a trusted block explorer.

7. Save the address in the tracker’s wallet list.

Because most modern trackers support xpub (extended public key) import, you can also generate an xpub offline and paste it into the app. This method eliminates any USB connection, further reducing attack surface.

Security Best Practices for Portfolio Tracking <a name="security-best-practices"></a>

1. Use a Dedicated Device for Tracking

- When possible, connect your hardware wallet to a machine that does not store any wallets or private keys. A clean, freshly installed operating system minimizes malware risk.

2. Enable Two‑Factor Authentication (2FA) on the Tracker

- Most portfolio apps now support 2FA via authenticator apps (e.g., Google Authenticator). Enable it to protect your account from credential‑theft attacks.

3. Validate SSL/TLS Certificates

- Ensure the tracker’s web endpoints present a valid certificate issued by a trusted authority. A mismatched certificate can indicate a man‑in‑the‑middle (MITM) attack.

4. Limit Permissions

- Auditing logs inside the tracker can reveal when and how address data was queried. Turn off any optional “Auto‑Sync” features that push data to third‑party servers unless you explicitly need them.

5. Regularly Review Connected Devices

- Portfolio apps often show a list of connected hardware wallets. Review this list weekly and remove any devices you no longer use.

6. Backup the xpub/Derivation Path

- Store the extended public key and derivation path in an encrypted offline file. If the tracker’s database ever becomes corrupted, you can re‑import the xpub without needing the hardware device again.

Statistical insight: A 2026 security audit of 150 portfolio tracking applications discovered that 12 % stored public address data in plaintext on the device’s local storage. Choosing an app that
