How to export your wallet's xpub (BlueWallet, Sparrow, Electrum, Ledger, Trezor)

What the xpub is — and why it is safe

The extended public key (xpub, ypub or zpub) only lets someone view your wallet's addresses and incoming funds. Stackfy uses it watch-only: it derives a fresh address per invoice and watches the blockchain to confirm the payment. It cannot spend anything.

Never hand over your recovery phrase (the 12/24 words) or private key (xprv) — not to Stackfy, not to anyone. When registering, paste a key starting with xpub, ypub or zpub (Stackfy validates it and rejects seeds/private keys).

BlueWallet (mobile)

1. Open the app and tap your Bitcoin wallet.
2. Tap the details icon in the top-right corner (opens “Wallet details”).
3. Tap Show wallet XPUB.
4. The key appears (usually starting with zpub) with a QR code. Tap to copy and paste it into Stackfy.

Your 12-word phrase is not exported here — and should not be.

Sparrow (desktop)

1. Open your wallet in Sparrow.
2. Click the Settings tab (gear, on the left).
3. Under Keystores, copy the xPub / Extended Public Key field (starts with xpub or zpub).
4. Paste it into Stackfy.

Only the public key is exposed — the seed stays offline.

Electrum (desktop)

1. Open your wallet in Electrum.
2. In the top menu, go to Wallet → Information.
3. Copy the Master Public Key (starts with xpub or zpub).
4. Paste it into Stackfy.

Ledger (Ledger / Ledger Live app)

1. Open the app and select your Bitcoin account.
2. Open the account options (gear icon / Edit account).
3. Open the Advanced section and copy the xpub (copy only the key characters).
4. Paste it into Stackfy.

Menu labels may vary by app version.

Trezor (Trezor Suite)

1. In Trezor Suite, select the account in the sidebar.
2. Open the Details tab.
3. Click Show public key.
4. The key appears as text and a QR code. Copy it into Stackfy, checking the characters match your device screen.

USDT on Tron — it is an address, not an xpub

To receive USDT on Tron (TRC-20), Stackfy does not ask for an xpub: just the public address of your Tron wallet, which starts with T.

1. In your wallet (e.g. Trust Wallet, TronLink) open USDT (TRC-20) or TRON (TRX).
2. Tap Receive and copy the address (starts with T).
3. Paste it into Stackfy's USDT field.

From an exchange, use the USDT deposit address on the Tron (TRC-20) network. Always check the network: TRC-20.

USDT on Polygon — also an address (not an xpub)

Stackfy also accepts USDT on Polygon. Like Tron, it is not an xpub: just the public address of your Polygon wallet, which starts with 0x.

1. In your wallet (e.g. MetaMask, Trust Wallet) select the Polygon network.
2. Copy your account address (starts with 0x) — it is the same for all tokens on Polygon.
3. Paste it into Stackfy's Polygon / USDT field in your store.

From an exchange, use the USDT deposit address on the Polygon network. Always check the network: Polygon (PoS) — sending over another network can lose the funds.
