- Lightning Seconds-fast small payments
At a glance
The cleanest way to run a hot Bitcoin wallet for spending while your savings sit on a signing device.
Best for: Bitcoin spending, Lightning and watch-only vaults · Maker: BlueWallet
Immune by construction, not by effort
The most common way people lose crypto from a software wallet is not a stolen key. It is a token approval — a standing permission granted to a smart contract, which the contract later exercises to move your tokens out. The wallet signed exactly what you asked it to. Nothing was hacked.
Bitcoin has no token approval mechanism. There is no allowance to grant, no contract to authorise, no standing permission that can be exercised later. A Bitcoin transaction moves a specific amount to a specific address once, and that is the entire vocabulary. The result is that BlueWallet is immune to the largest category of software wallet loss — not because its developers built a clever defence, but because the asset it handles does not have the feature that gets exploited.
This is worth stating plainly, because it is a genuinely strong argument and it gets lost in debates about interfaces and chain counts. If you hold only Bitcoin, choosing a Bitcoin-only wallet removes an entire class of risk for free. The same reasoning is why Coldcard and BitBox02's Bitcoin-only edition exist on the hardware side.

Watch-only vaults, which nobody else does properly
This is our favourite feature in any software wallet, and it solves a real problem that most cold storage advice simply tells you to live with.
The problem: once you move Bitcoin to a hardware wallet, checking it becomes inconvenient. You have to find the device, plug it in, open the companion software. So people either check obsessively in a way that involves handling the device more than they should, or they never check and lose track of what they hold — and occasionally discover a problem years after it would have been fixable.
BlueWallet's answer is to let you import the extended public key from your hardware wallet. That key can derive all your receiving addresses and therefore show your balances and full transaction history — and it mathematically cannot spend anything, because spending requires the private key, which stays on the device. You get complete visibility on your phone with zero additional risk. You can even construct an unsigned transaction on the phone and take it to the device to sign later.
There is one privacy caveat worth knowing. An extended public key reveals all your addresses to whatever server the wallet queries for balances, which means that server can see your whole holding as a cluster. BlueWallet lets you point it at your own Electrum server or node if that matters to you. For most people the convenience is worth the disclosure; if it is not, run your own. Our tracking and traceability guide covers what this exposes.
The setup we would run for Bitcoin
A hardware wallet holding the savings, its extended public key imported into BlueWallet as a watch-only vault so you can see it any time, and a separate small on-chain or Lightning balance in BlueWallet for actual spending. One device, one free app, complete visibility, and no confusion about which balance is which.
Lightning: useful, and not for savings
BlueWallet handles Lightning, which settles small Bitcoin payments in seconds for negligible fees. For actually spending Bitcoin — as opposed to holding it — this is the practical route, and BlueWallet's implementation is one of the more approachable.
What to understand is that a Lightning balance is a fundamentally different thing from on-chain Bitcoin. Funds sit in payment channels, which involve liquidity, routing and counterparties in ways on-chain Bitcoin does not. It is designed for payments and it is excellent at them. It is not designed as a store of value, and treating a Lightning balance as savings is a category error.
The rule we would apply: keep in Lightning only what you intend to spend in the next few weeks. Keep savings on-chain and cold. The two are not competing — they are different tools, and BlueWallet is unusual in handling both without pretending they are the same.
The balance sheet
What we like, and what we don't
What it does well
- Fully open source, so every security claim is independently verifiable
- Structurally immune to token-approval drains, because Bitcoin has no approval mechanism to exploit
- Watch-only vaults let you monitor a hardware wallet from your phone with no private keys involved
- Lightning support for fast, negligible-cost small payments
- Clean, focused interface with no altcoin list, no NFT tab and no earn panel
- Works with hardware wallets, so it can be the interface to your cold storage rather than a competitor to it
- Free with no swap spread, because there is nothing to swap
What we hold against it
- Bitcoin and Lightning only — useless for any other asset
- No staking, because Bitcoin has none
- Lightning channel management is conceptually harder than on-chain Bitcoin and easy to misunderstand
- Interface is functional rather than delightful; it trails Phantom on polish considerably
- Keys are still on an internet-connected phone for on-chain wallets you hold locally
- Smaller mainstream profile means less troubleshooting material than MetaMask or Trust Wallet
Interface: functional, not delightful
We score BlueWallet 8.0 on interface, which is solid but well behind Phantom's 9.3. The gap is honest and worth characterising, because it is not a criticism of anyone's competence.
BlueWallet is built by Bitcoin people for Bitcoin people. It uses the correct terminology rather than simplified terminology, it exposes concepts like extended public keys and channel management rather than hiding them, and it does not hold your hand. For someone who already understands Bitcoin that is exactly right — you can see what is happening and nothing is being decided on your behalf. For a complete beginner, "import an xpub as a watch-only vault" is a sentence that requires prior knowledge.
The other side of that austerity is what is absent, and it is a lot: no token list, no NFT gallery, no earn tab, no swap widget with an embedded spread, no buy panel from a third-party broker. The app does Bitcoin and Lightning and nothing else, which means there is nothing in it trying to extract a percentage from you. Given how much of every other wallet's interface is now commercial surface, that restraint is worth a great deal.
Using it from New Zealand
Funding is the only New Zealand-specific consideration, and it is the same as for every other software wallet. BlueWallet has no fiat on-ramp of its own worth using, so the route is to buy Bitcoin on a venue with published licences and withdraw to the receiving address BlueWallet gives you. Send a small test amount first, confirm it arrives, then send the rest. Our NZD funding guide covers what the local on-ramp looks like now that Easy Crypto stopped trading on 30 March 2026 and Kiwi-Coin closed.
On the tax side, BlueWallet's simplicity helps. Bitcoin generates no staking rewards and no airdrops, so you are not accumulating hundreds of small taxable receipts. What you need is a record of each acquisition and each disposal with the New Zealand dollar value on the day. Transfers between your own wallets are not disposals. From 1 April 2026 the platforms either side of your wallet report to Inland Revenue under CARF, so your own records should reconcile with what they send. Our tax and CARF guide has the detail. General information, not tax advice.
Our view
There is a version of this whole subject that is much simpler than the one this site mostly describes: hold only Bitcoin, keep it on a hardware wallet, watch it from BlueWallet, spend from a small Lightning balance, and never connect a wallet to anything. No approvals, no bridges, no token contracts, no swap spreads, no chain selection errors. A great many of the losses we have written about on other pages are simply not available to a person living that way.
BlueWallet FAQ
BlueWallet — questions New Zealanders ask
Is BlueWallet safe for Bitcoin?
It is one of the safer software wallets available, for a structural reason rather than a marketing one: because Bitcoin has no token-approval mechanism, the entire category of approval-drain attacks that empties Ethereum and Solana wallets simply cannot happen here. There is nothing to approve. Add fully open-source code and a watch-only mode that lets you monitor cold storage without keys present, and you have the most defensible hot wallet on this site. The keys are still on a phone, which is the limit of any software wallet.
What is BlueWallet watch-only mode?
You import the public key or extended public key from your hardware wallet, and BlueWallet can then show you balances and transaction history for that wallet — without the private keys ever being on your phone. It is genuinely useful: you get to check your cold storage from your pocket, and even build unsigned transactions to sign on the device later, with no risk to the keys. Almost nothing else offers this as cleanly, and it is our favourite feature in the app.
Should I use Lightning in BlueWallet?
For small, fast payments, yes — Lightning settles in seconds for negligible fees and BlueWallet's implementation is straightforward. Understand that Lightning balances live in payment channels and are a different risk model from on-chain Bitcoin: they are designed for spending, not saving. Keep only what you intend to spend there, keep savings on-chain in cold storage, and do not treat a Lightning balance as a long-term store of value.
Can BlueWallet connect to a hardware wallet?
Yes. BlueWallet supports hardware wallet workflows including watch-only vaults and signing coordination, which lets you use it as a convenient interface while a device holds the keys. This is the arrangement we would recommend for a Bitcoin holder: cold storage on a device, BlueWallet on the phone for visibility and for a small spending balance, and no confusion about which is which.
