When it comes to securing your stake.link (SDL) assets, few solutions offer the blend of simplicity, durability, and military-grade security like Tangem’s hardware wallet. Designed for both beginners and experienced crypto holders, Tangem delivers a seamless way to store, manage, and protect your digital wealth—offline.
In this comprehensive guide, we’ll walk you through everything you need to know about using Tangem as your go-to cold wallet for stake.link, including how it works, why it’s secure, and how it compares to other wallet types.
What Is stake.link (SDL)?
stake.link, represented by the SDL token, plays a pivotal role in its ecosystem built on the Ethereum blockchain. This ensures high security, decentralization, and broad interoperability with various decentralized applications (dApps). The SDL token enables governance voting, transaction fee payments, and grants users access to priority staking features within the platform.
As blockchain assets exist on the network—not inside wallets—your wallet’s real job is to securely manage the private keys that give you control over those assets.
Understanding stake.link Wallets
A stake.link wallet is a tool that generates and safeguards the private keys required to access your SDL holdings. It allows you to send, receive, store, and monitor your tokens across the Ethereum network. While the tokens themselves live on-chain, your wallet acts as the secure gateway to interact with them.

How Do stake.link Wallets Work?
At the core of every stake.link wallet is a cryptographic system based on public-private key pairs:
- The private key must remain secret—it's what proves ownership and authorizes transactions.
- The public key (or wallet address) can be safely shared to receive funds.
To transfer or spend SDL tokens, your wallet uses the private key to sign transactions. With Tangem, this critical process happens securely within a tamper-resistant chip—ensuring your keys never touch an internet-connected device.
Types of stake.link Wallets
Not all wallets offer the same level of protection. Here are the main categories:
Exchange-Based Wallets
Centralized platforms like Binance or Coinbase provide custodial wallets that make buying SDL easy. However, you don’t fully control your private keys—meaning you're trusting a third party with your assets. This introduces risks such as platform outages, account freezes, or exchange hacks.
Software Wallets
These include mobile, desktop, and browser extensions (like MetaMask) that store keys on your device. While convenient for daily use, they’re vulnerable to malware, phishing attacks, and device theft.
Mobile & Desktop Wallets
Mobile apps allow on-the-go management of SDL but rely on smartphone security. Desktop versions offer more control but still expose keys to potential online threats if the system is compromised.
Hardware Wallets (Cold Storage)
Hardware wallets like Tangem keep private keys completely offline, offering superior protection against cyberattacks. They combine robust physical security with intuitive interfaces—making them ideal for long-term holding.

Why Choose Tangem for Your stake.link Wallet?
Tangem stands out in the crowded hardware wallet space due to its unique combination of security, usability, and resilience:
- No Seed Phrases: Unlike traditional wallets that require 12- or 24-word recovery phrases (which can be lost or stolen), Tangem uses a smart backup system across multiple cards—eliminating single points of failure.
- Military-Grade Durability: Rated IP69K for dust and water resistance, Tangem cards withstand extreme temperatures, electromagnetic pulses (EMP), electrostatic discharge (ESD), and even X-ray exposure.
- Biometric & PIN Protection: Prevent unauthorized access with biometric authentication and a secure passcode.
- EAL6+ Secure Element: Private keys are generated and stored in a certified secure chip—the same level used in banking cards and government IDs.
This makes Tangem one of the most secure ways to hold your stake.link tokens without sacrificing ease of use.
Core Security Features of Tangem
Let’s dive deeper into what makes Tangem a top-tier choice:
- Offline Key Generation: Keys are created directly on the card during setup—never exposed to your phone or computer.
- Zero Internet Exposure: Since no data is transmitted online during transactions, there’s no attack vector for hackers.
- Tamper-Evident Design: Any attempt to physically breach the chip destroys its functionality.
- Multi-Card Backup System: Instead of relying on a single seed phrase, Tangem lets you create backups across several cards—only a subset is needed to restore access.
These features make Tangem especially suitable for long-term holders who prioritize asset protection over frequent trading.

Frequently Asked Questions (FAQ)
Q: Where can I buy stake.link (SDL) tokens?
A: You can purchase SDL on major exchanges like Binance, Coinbase, or Kraken. Peer-to-peer platforms and crypto converters are also options. Always transfer your holdings to a secure wallet like Tangem after purchase.
Q: Is a hardware wallet necessary for stake.link?
A: For long-term storage, absolutely. Hot wallets are convenient but exposed to online risks. A cold wallet like Tangem offers maximum protection against hacking and theft.
Q: Are there fees when transferring SDL?

Q: What happens if I lose my Tangem card?
A: If you’ve created backup cards, you can restore access using any combination of them. Without backups, recovery isn’t possible—so always complete the backup process during setup.
