How to Set Up and Use a Nano Wallet: A Step-by-Step Guide
So, you've learned about Nano (XNO) and its incredible potential for instant, feeless payments. Now you're ready to take the next step: getting your own Nano wallet. A crypto wallet is your personal gateway to the network—it’s how you securely store, send, and receive your XNO.
Setting up a wallet can seem intimidating, but it’s actually a quick and simple process. This guide will walk you through every step, from choosing the right type of wallet to making your first transaction.
Before You Start: Custodial vs. Non-Custodial Wallets
First, it’s essential to understand the two main types of wallets:
- Custodial Wallets: These are wallets managed by a third party, like a cryptocurrency exchange (e.g., BYDFi, Binance, Kraken). They are convenient and easy to use, but you don’t have full control over your private keys. It’s like keeping your money in a bank.
- Non-Custodial Wallets: With these wallets, you are in complete control. You hold the private keys (your “secret phrase”). This offers maximum security and self-sovereignty but also means you are solely responsible for keeping your funds safe. It’s like keeping cash in your own personal vault.
For this guide, we will set up a popular non-custodial mobile wallet called Natrium, known for its simple and elegant user interface.
Setting Up Your Nano Wallet with Natrium: 4 Simple Steps
Follow these steps to get your wallet up and running in minutes.
Step 1: Download the Official Application
Go to the official App Store (for iOS) or Google Play Store (for Android) on your phone. Search for "Natrium" and download the official app. Always double-check that you are downloading the legitimate application to avoid scams.
Step 2: Create a New Wallet & Secure Your Secret Phrase
When you first open the app, you'll be given two options: "Create a New Wallet" or "Import Existing Wallet."
- Select "Create a New Wallet."
- The wallet will now generate a Secret Phrase (also known as a seed phrase or mnemonic phrase). This is a list of 24 random words.
CRITICAL: This Secret Phrase is the master key to all your funds. Write it down on a piece of paper and store it in a safe, private place where no one else can find it. Never store it as a screenshot, in a text file on your computer, or in a cloud service like Google Drive. If you lose this phrase, you lose your Nano forever.
Step 3: Confirm Your Backup
To ensure you have correctly saved your Secret Phrase, the app will ask you to confirm it. This proves you have a secure backup, which is the only way to recover your wallet if you lose your phone.
Step 4: Secure Your Wallet
Finally, you will be prompted to set up a security PIN and enable biometric authentication (Face ID or fingerprint) if your phone supports it. This protects your wallet from unauthorized access on a day-to-day basis.
Congratulations! You now have a secure, fully functional Nano wallet.
How to Use Your New Nano Wallet
Now for the fun part—using your wallet for feeless and instant transactions.
How to Receive Nano (XNO)
To receive funds, you need to share your Nano address.
- On the main screen of your wallet, tap the "Receive" button.
- A QR code will appear along with a long string of characters starting with "nano_". This is your public address.
- You can either let someone scan the QR code or tap the "Copy Address" button to share it. It is completely safe to share this public address with anyone.
How to Send Nano (XNO)
- On the main screen, tap the "Send" button.
- Enter the amount of XNO you wish to send.
- You can either paste the recipient's Nano address or tap the QR code icon to scan their code.
- Review the details and confirm the transaction. The XNO will arrive in their wallet in less than a second, with zero fees deducted.
Final Security Reminders
- Your Secret Phrase is Everything: Never share it with anyone. No legitimate support team will ever ask for it.
- Start Small: Send a small test transaction first to get comfortable with the process.
- Consider a Hardware Wallet for Large Amounts: For significant holdings, consider storing your Nano on a hardware wallet (like a Ledger or Trezor) for the ultimate level of security.
Setting up and using a Nano wallet is an incredibly simple and rewarding experience. It unlocks the true power of the Nano network, allowing you to participate in a global financial system that is instant, feeless, and open to everyone.Now that your wallet is ready, you can buy XNO from an exchange or start using it for payments. To learn more about the technology that makes this all possible, read our detailed guide: What Is Nano (XNO) Crypto? (This is where you'd link to your main pillar article).
This guide is for informational purposes only. Be aware of the risks associated with managing your own cryptocurrency. The responsibility for securing your private keys and your funds is yours alone. Always do your own research before using any third-party wallet or application.2026-01-16 · 19 days ago2025’s Top Ordinals Wallets: Store and Trade Your Bitcoin NFTs Safely
Best Ordinals Wallets in 2025: A Human Guide to Securing Your Bitcoin NFTs
If you’ve been scrolling through crypto Twitter or hanging out in Discord channels lately, chances are you’ve seen people talking about Bitcoin Ordinals. Maybe you’ve even asked yourself: Alright, but which wallet should I actually use to keep these things safe?
That’s exactly what we’re going to unpack here. And don’t worry—I’ll keep it conversational and easy to follow, even if you’re brand new to this space. By the end, you’ll not only know what wallets to trust but also how to fund them, even if your credit history isn’t the best.
So, What Are Bitcoin Ordinals Anyway?
Let’s start with the basics. A Bitcoin Ordinal is essentially a digital collectible (think NFT) that’s etched directly onto a satoshi—the tiniest slice of Bitcoin. To put that in perspective, 1 Bitcoin equals 100 million satoshis, and thanks to Ordinals, each of those tiny sats can now carry unique data like a picture, a song, a video, or even text.
What makes them so exciting is that unlike many NFTs on Ethereum or Solana, Ordinals live directly on the Bitcoin blockchain. There’s no separate layer, no reliance on external servers—it’s as forever as anything can get in crypto. Once something is inscribed, it’s there for good.
But here’s the kicker: you can’t just toss these into any old Bitcoin wallet. Regular wallets don’t understand Ordinals, and worse, they might accidentally spend your collectible without realizing it. That’s why you need a dedicated Ordinals wallet—one that supports Taproot addresses and knows how to handle inscriptions safely.
The Top Ordinals Wallets in 2025
Alright, let’s get into the good stuff. Which wallets are worth your trust this year? I’ve tested and researched quite a few, and here are the ones that stand out.
1. Xverse Wallet – Best All-Rounder
If you’re looking for a wallet that’s friendly enough for beginners but still loaded with advanced features, Xverse is a top pick. The interface feels smooth and modern, not like those clunky old crypto apps.
It supports not only Ordinals but also BRC-20 tokens (the fungible side of Bitcoin’s new ecosystem) and even Stacks assets. On top of that, you get handy security features like biometric login and Ledger integration, so if you’re serious about safety, you can pair it with a hardware wallet.
One thing I love? Xverse lets you buy Bitcoin directly inside the app using fiat. No need to go hopping between exchanges just to top up your wallet. For someone dipping their toes into Ordinals, that’s a huge plus.
2. Phantom Wallet – Best for Multichain Users
You might know Phantom from the Solana world, but in 2025, it’s become a true multichain wallet. Yes—Bitcoin Ordinals are supported here too.
What sets Phantom apart is its visual experience. Your Ordinals don’t just sit as text or transaction hashes—you can actually see them in a gallery-like view. That makes collecting feel more real, more like browsing an art collection than scrolling through a spreadsheet.
If you dabble across multiple blockchains—say you’ve got some Solana NFTs, some Ethereum tokens, and now you’re diving into Bitcoin Ordinals—Phantom is a lifesaver. It keeps everything under one roof.
3. Ordinals Wallet – Best for Hardcore Collectors
This one was built for Ordinals from the ground up. The community is massive (over 875,000 inscriptions already, and growing), and the wallet offers features like multi-signature security and DeFi integrations.
If you see yourself more as a collector than a casual dabbler, this is a solid home base. It’s also where a lot of Ordinals trading happens, so you’ll likely feel plugged into the community just by using it.
4. Leather Wallet (formerly Hiro) – Best for Open-Source Fans
Leather is a rebrand of the old Hiro wallet, and while it’s not as flashy as Phantom or as specialized as Ordinals Wallet, it’s dependable. It’s open-source, audited, and has over 100,000 active users.
I’d say Leather is perfect if you value transparency and prefer to use tools that the community can openly inspect. The trade-off is that it doesn’t have all the bells and whistles of some newer wallets.
5. UniSat Wallet – Best for BRC-20 Traders
If you’ve heard of BRC-20 tokens, UniSat is probably why. This wallet pioneered support for them and even built its own marketplace. For traders who want to experiment with Bitcoin-based tokens as well as Ordinals, UniSat is hard to ignore.
That said, its setup can be confusing if you’re brand new—especially around how it handles Ordinals addresses. Still, for active traders, the flexibility makes it worth the learning curve.
Funding Your Ordinals Wallet (Even If Your Credit Isn’t Perfect)
Okay, so you’ve picked a wallet. Now comes the next step: getting Bitcoin into it.
Most wallets today, like Xverse or Phantom, have built-in fiat on-ramps. That means you can link your bank card and buy Bitcoin directly without going to an exchange like Coinbase or Binance first. Super convenient.
But let’s be real—sometimes getting a card approved isn’t easy, especially if your credit score has taken a few hits. The good news is, you still have options.
1- Secured credit cards are probably your best bet. For example, the Discover it® Secured Credit Card only requires a refundable deposit. It doesn’t charge an annual fee, and it can actually help you rebuild credit while you buy Bitcoin.
2- Another approachable option is the Capital One Platinum Secured Card. It’s widely considered one of the easiest unsecured cards to get, thanks to its low deposit requirements.
Once you’ve got one of these in hand, you can use it to buy Bitcoin directly in your wallet app—or through an exchange if you prefer—and then transfer it safely to your Ordinals wallet.
Final Thoughts
The world of Bitcoin Ordinals is still young, but it’s moving fast. Choosing the right wallet early can save you a ton of headaches later. If you want something simple and reliable, go with Xverse. If you’re an NFT collector who loves browsing a gallery-style setup, Phantom will feel like home. And if you’re a serious trader or collector, Ordinals Wallet and UniSat have you covered.
At the end of the day, the best wallet is the one that matches your goals: are you casually collecting, actively trading, or building a long-term stash of rare inscriptions?
If this is your first time buying crypto, don’t overcomplicate things. Start with BYDFi—it’s designed for beginners, has clear fees, and lets you buy Bitcoin with just a few clicks.
2026-01-16 · 19 days agoWhat Is Saga and How Saga Enables Unlimited Horizontal Scaling for Crypto ?
Key Points
- Saga is a revolutionary layer-1 blockchain platform enabling developers to deploy custom appchains with ease.
- It allows infinite horizontal scaling, letting each appchain (chainlet) operate independently.
- Developers can leverage multiple virtual machines including EVM, Solana VM, MoveVM, and more.
- Saga offers shared security, removing the need for separate validator networks for each appchain.
- Its native token, SAGA, supports ecosystem growth, incentives, and developer programs.
What Is Saga? Unlocking Infinite Scaling for the Future of Crypto
In the ever-evolving world of blockchain, scalability has long been the holy grail. The rise of decentralized applications, booming DeFi ecosystems, and the explosive growth of gaming and entertainment on-chain have highlighted one undeniable truth: traditional blockchains struggle to keep up.
Enter Saga, a groundbreaking Layer-1 solution designed to empower developers to deploy their own independent blockchains — or chainlets — unlocking near-limitless horizontal scaling for the crypto ecosystem.
From Monolithic Chains to Appchains: The Evolution of Scaling
In the early days, most blockchains were built as monolithic structures. A single chain handled everything — from consensus and transaction execution to settlement and data availability. This setup worked when blockchain activity was minimal. However, as adoption surged, cracks began to appear. Ethereum, for example, faced skyrocketing gas fees during the ICO boom of 2017 and again during the 2020–2021 bull market, with transaction costs sometimes hitting the hundreds or even thousands of dollars.
These challenges pushed developers to rethink scaling strategies. Ethereum introduced rollups, which moved transaction execution to separate Layer-2 chains while still anchoring security on the main Layer-1 chain. By batching transactions together, rollups drastically reduced fees for users while maintaining security.
Meanwhile, the Cosmos ecosystem pioneered the concept of appchains — specialized chains designed for a single purpose, whether a decentralized exchange (DEX), a lending platform, or a gaming application. This approach allowed developers unprecedented flexibility and customization, inspiring other projects such as Avalanche with subnets, Polygon with zero-knowledge Ethereum Virtual Machine (zkEVM) chains, and independent Ethereum L2 deployments.
Yet, even with these options, deploying highly customized, secure, and scalable solutions remained complex — until Saga appeared.
Saga: The Gateway to Infinite Horizontal Scaling
Saga positions itself as a one-stop platform for developers, enabling them to deploy dedicated appchains effortlessly. Instead of building a chain from scratch, developers can simply deploy their smart contract binary to the Saga mainnet. Saga’s validators then process the deployment automatically, creating a dedicated chainlet tailored to the developer’s project.
What makes Saga unique is its approach to flexibility and independence. Each chainlet hosts only a specific set of smart contracts, ensuring predictable transaction fees and optimized performance. Developers are not constrained by the blockspace limitations of a shared chain. Additionally, Saga is VM-agnostic, supporting multiple virtual machines such as the Ethereum Virtual Machine (EVM), Solana VM, MoveVM, and others. This allows teams to build using the technology best suited for their project. Moreover, Saga’s modular architecture allows chainlets to be updated independently, without impacting other chainlets or the main network — a game-changer for continuous development and innovation.
Security and Parallelization: Solving Early Appchain Challenges
One of the most difficult aspects of launching an appchain has traditionally been securing it. Building and managing a validator set while maintaining network security often proved too costly or complicated for smaller projects. Saga tackles this issue by offering shared security across all chainlets. Its validators are orchestrated to manage thousands of chainlets running simultaneously, ensuring both safety and reliability.
Saga also leverages parallelization, meaning each chainlet operates independently, free from competition for resources. Developers can even shard a single application across multiple chainlets. Imagine an automated market maker splitting its operations into chainlets for each liquidity pool — this structure allows virtually unlimited scaling and performance optimization.
While Saga initially targets gaming and entertainment, where high-speed transaction processing is crucial, DeFi applications can also harness its capabilities to unlock new financial primitives and advanced protocols.

2026-02-03 · 18 hours agoUmbra Protocol: The Future of Private Crypto Payments?
Key Takeaways:
- Umbra protocol uses "Stealth Addresses" to allow users to pay each other privately on public chains like Ethereum.
- Unlike mixers which obfuscate the source of funds, Umbra ensures only the receiver can see who got paid.
- This technology offers a compliance-friendly alternative for businesses that need privacy for payroll and contracts.
The Umbra protocol is solving one of the most glaring problems in the cryptocurrency space. We call it the "Privacy Paradox." Everyone wants the security of a public blockchain, but nobody wants their salary, spending habits, or net worth broadcast to the entire world.
In the past, privacy meant using "mixers" like Tornado Cash. However, as we discussed recently, regulators view mixers as tools for money laundering. This created a massive gap in the market for a privacy solution that protects the user without breaking the law.
How Does a Stealth Address Work?
The innovation behind the Umbra protocol is the concept of "Stealth Addresses." When you send money to someone on a standard blockchain, you send it to their public address (e.g., vitalik.eth). Anyone watching that address knows exactly how much money they received.
With Umbra, the sender uses the recipient's public key to generate a brand new, unique address on-chain. This address has never been used before.
The funds are sent to this new address. Only the receiver holds the private key to unlock it. To an outside observer, it just looks like a random transfer to a random wallet. There is no visible link between the sender and the receiver's main identity.
Is It Different from a Mixer?
Yes, fundamentally. Mixers pool everyone's money together to hide where it came from. The Umbra protocol does not touch the source of the funds.
It simply ensures that the destination is private. It is like mailing a letter to a PO Box instead of a home address. The postman (the blockchain) delivers the letter, but nobody knows who actually picked it up.
This distinction is critical for 2026. It allows businesses to pay employees in crypto without revealing their salaries to the entire company. It allows vendors to pay suppliers without revealing their entire balance sheet to competitors.
Why Does Privacy Matter for Mass Adoption?
For crypto to replace banking, it needs basic privacy standards. You wouldn't use a bank that published your credit card statement on a public billboard.
The Umbra protocol provides this missing layer of financial hygiene. It allows the Ethereum ecosystem to remain transparent for verification but private for individual user rights. It protects users from "doxing" and targeted phishing attacks by keeping their main wallet addresses disconnected from their daily spending.
Conclusion
Privacy is not about hiding crimes; it is about protecting dignity. As regulators crack down on total anonymity, stealth address technology offers a middle ground that works for everyone.
Whether you value privacy or transparency, you need a safe place to acquire your assets. Register at BYDFi today to buy Ethereum and stablecoins on a platform that prioritizes user security.
Frequently Asked Questions (FAQ)
Q: Is Umbra legal to use?
A: Currently, yes. Since it is not a mixer and does not obscure the source of funds, it has not faced the same sanctions as Tornado Cash.Q: Does Umbra work on Bitcoin?
A: No. The Umbra protocol is built for EVM-compatible chains like Ethereum, Optimism, and Arbitrum.Q: Can I recover funds sent to a stealth address if I lose my key?
A: No. Just like any self-custodial wallet, if you lose the private key generated for that transaction, the funds are lost forever.2026-01-28 · 7 days agoLedger Data Leak: How Phishing Attacks Target Hardware Wallets
Key Takeaways:
- The leak compromised user contact information like emails and physical addresses, not their private keys.
- Hackers use this data to send convincing phishing emails and fake hardware devices to victims.
- Physical security, using a PO Box, and knowing how to report scams are just as important as the security of the hardware wallet itself.
The Ledger data leak remains one of the most significant security lessons in the history of the cryptocurrency industry. While hardware wallets are often touted as the ultimate security solution for holding Bitcoin and Ethereum, this incident proved that the weak link isn't always the technology. It is the database storing the customer information.
When a third-party marketing provider (like Shopify) or a database is compromised, it exposes the names, emails, and home addresses of the people who bought the devices. This allows criminals to bypass the digital encryption and attack the user directly through social engineering.
Was the Hardware Device Hacked?
It is crucial to understand that during the Ledger data leak, the actual hardware wallets remained 100% secure. The private keys never left the device. The secure element chip inside the Ledger was not breached.
However, the damage was psychological. Thousands of users found themselves targeted by sophisticated campaigns. Because the hackers knew exactly who bought a device, they could craft hyper-realistic emails.
These emails often claimed that the device was "defective" and needed a firmware update immediately. They provided a link to a fake version of Ledger Live. Ledger Live is the official desktop and mobile application that acts as the dashboard for the device. It is where users view balances and send transactions. By mimicking this trusted software, hackers tricked users into typing their seed phrases into a malicious window, resulting in total loss of funds.
How Do the Phishing Attacks Work?
The aftermath of a Ledger data leak involves a barrage of phishing attempts. Some victims even received modified hardware devices in the mail. These devices looked legitimate but had been tampered with to steal funds as soon as they were connected.
Most attacks are digital. Scammers send text messages or emails threatening that funds are "at risk" unless the user verifies their identity. They exploit fear.
The golden rule remains unchanged: A legitimate hardware wallet manufacturer will never ask for your 24-word recovery phrase. If an email asks for it, it is a scam derived from the leaked data.
How Do You Report a Phishing Attempt?
If a suspicious email lands in your inbox, simply deleting it helps you, but reporting it helps everyone. Most email providers like Gmail and Outlook have a built-in "Report Phishing" button located in the dropdown menu next to the reply arrow.
You should also alert the company being impersonated. In the case of this specific Ledger data leak, you can forward the fraudulent email to Ledger’s official security team or interact with their official support bot on their website. This helps them identify the malicious domain and work with authorities to take the site offline before other users fall victim.
How Can You Protect Your Privacy?
To protect yourself from a future Ledger data leak, you should minimize the data you give to crypto companies. When ordering a hardware device, consider using a PO Box (Post Office Box).
A PO Box is a lockable mailbox located at a physical post office station, rather than at your home. By shipping the device to a PO Box, you ensure that your home address never enters the company's database. If a leak occurs, criminals only find the address of a public building, not the location where you and your family sleep.
Conclusion
Hardware wallets are still excellent tools, but they cannot protect you from social engineering. The Ledger data leak taught us that we must be vigilant about our physical and digital footprint. Your keys might be safe, but your personal information is a weapon that can be used against you.
If you prefer to avoid the risks of self-custody and shipping physical devices, you can use a regulated platform. Register at BYDFi today to store and trade your assets with institutional-grade security.
Frequently Asked Questions (FAQ)
Q: Did Ledger lose my private keys?
A: No. Ledger does not have access to your private keys. Only the marketing data (email, phone, address) was part of the Ledger data leak.Q: Is it safe to buy a Ledger now?
A: Yes, the devices themselves are secure. However, ensure you buy directly from the official manufacturer and never from a third-party reseller like eBay.Q: Does reporting a phishing email actually do anything?
A: Yes. Reporting helps email providers train their spam filters. It also provides evidence for the company's legal team to seize the hacker's website domain.2026-01-26 · 9 days ago
