To the uninitiated, the purpose of a cold wallet is to keep your crypto out of sight and out of mind. Like freezing turkey in July to avoid it going rancid before Thanksgiving in November, most apply the same idea to cold wallets. Just "freeze" crypto in there and return when its value has doubled or tripled.
Most Americans we surveyed compared it to keeping cash in a safe instead of a checking account—it's more secure but less convenient for quick access. We can take some blame for using the term "safer than a bank's vault."
There is some truth to this idea. Before Tangem, cold hardware wallets were challenging to use and typically reserved for experts with a strong understanding of blockchain technology. They opted for cold wallets, sacrificing major convenience for security. Even then, the vulnerabilities of seed phrases were a major security flaw.
"But the year is 2024, so why can't you have both?"
Technology has improved every facet of our lives. From air conditioning to drive-through food, TV dinners, microwave ovens, and air fryers and beyond, innovators have brought an almost endless list of devices, products, and services that have made life simpler.
Take the automobile for example. It was already a big step from horse-pulled carts. Still, the introduction of the automatic gearbox simplified vehicle operation, making driving more accessible to a broader population, including those who found manual transmissions challenging.
To make crypto simpler and cold wallets more accessible, we had to think differently.
Everything Tangem does has always been to simplify your crypto experience: durable plastic cards that can slip into your pockets, NFC for easy and secure information transfer, and a well-designed mobile app. Sending and receiving cryptocurrency is standardized across all crypto wallets, but we simplified that.
People flock to cryptocurrencies because they consider them a new asset for the modern age. Swapping—primarily cross-chain swaps—is one of the most common ways people earn profit by exchanging one token for another. To swap profitably, you have to
- Onramp quickly and cost-effectively
- Get the best rates on the market
- Make the transaction quickly
- Do it securely without exposing your private keys
This is where Tangem Express comes in.
What is Tangem Express?
Tangem Express is a platform built into the tangem app that aggregates several DEX, CEX, blockchain bridges, onramp, and offramp services, providing a simple interface for buying, selling, and swapping cryptocurrencies in one place.
With Tangem Express, you can swap one cryptocurrency for another, bridge between different networks, transfer gas fees from one network to another, or even exchange tokens for gas within a network to ensure you have enough to cover transaction fees.
Sounds complex? You didn't have to know how the automatic transmission worked to enjoy riding in a modern car. You just paid attention to the brand's reliability index and safety records.
Tangem Express: Key advantages
Let's explore what Tangem Express means for you.
Unified swap, bridging, and gas transfer
Tangem Express combines the functions of same-chain swap, cross-chain swap, blockchain bridges, and gas transfers within a single interface. It allows you to exchange assets across networks and bridge tokens between blockchains without needing separate tools.
Secure and cost-effective transactions
Using different tools or exchanges for swaps, bridges, and gas transfers increases security risks due to multiple transactions and address entries. With Tangem Express, your assets remain in one environment without external transfers, reducing exposure to security breaches or human errors (like copying the wrong address).
It eliminates the need to withdraw assets to a centralized exchange and then return them to cold storage, which typically incurs withdrawal fees and exchange commissions.
Competitive rates via aggregation
Tangem Express aggregates rates from multiple providers—1Inch, ChangeNow, Changelly, ChangeHero, OKX DEX/Bridge—to offer competitive swap rates. This helps you get the best possible rate without switching or relying on one platform.
Enhanced security and privacy
With Tangem Express, you avoid the exposure of sharing addresses on external platforms, and transactions remain private as integrated swap providers do not store your addresses.
KYC-free swaps
Approximately 99.99% of exchanges on Tangem Express do not require Know Your Customer (KYC) verification. This helps preserve your privacy and provides an anonymous experience for your swaps.
Fast and efficient
Most transactions on Tangem Express are instantaneous or completed within a few minutes, allowing you to access your crypto quickly and without delay.
Dedicated customer support
In cases of unexpected issues, we offer dedicated customer support that is ready to help you resolve any concerns.
