ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Tammy! We're glad the ELLIPAL X Card was easy to set up and that you feel more confident holding your XRP through self-custody.

After transferring my crypto Elli leaves the address in memory which isn’t good

ELLIPAL X Card Cold Wallet

Store owner replied: Hi Kevin, a Wallet Address is public Blockchain information, and seeing an address in the ELLIPAL App does not expose your Private Key or give anyone control of your assets. If by 'address in memory' you mean a copied address, saved recipient, or another specific screen, please email cs@ellipal.com with a screenshot of that page so our team can identify exactly what you are seeing.

Very easy to use on all fronts

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Spencer! We're glad the ELLIPAL X Card has been easy to use across the entire experience.

It's great, as long as it protects my investment

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Paul! The ELLIPAL X Card protects your Private Key inside a CC EAL6+ certified Secure Chip, and each transaction requires the correct Card-PIN and physical NFC signing. Please also keep your Seed Phrase and Card-PIN securely backed up and private.

Really Ellipal Card is Amazing and easy to manage!😍🤩🥰

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Lucrecia! We're delighted that you find the ELLIPAL X Card easy to manage and enjoyable to use.

I ordered the Ellipal Titan mini. Now my crypto is safe and secure! The cold wallet is easy to use. I highly recommend the Ellipal system.

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Paul! We're delighted that you find your ELLIPAL cold wallet easy to use and that it gives you greater confidence in keeping your crypto secure.

I really don't know if the X Card is safe to use. I used to use Ledger. Money was missing. They blamed me. Only to find out there was a way the Nano X Plus could be hacked. They said this was impossible. When they ommitted that the chip had a attenna attached to send an receive. This makes me wonder. Now Elipal Be paying out also for data breaches also. Is this X Card hacked also. I don't know if it compromised also this is why I left a neutral response. Maybe my phone not being NFC Capable is the best for now. Maybe putting all my extra money being placed in a mason jar and buried in the back yard would be safer

ELLIPAL X Card Cold Wallet

Store owner replied: Hi Donald, we understand why your previous experience would make you cautious about another hardware wallet. The ELLIPAL X Card protects your private keys inside a CC EAL6+ certified secure chip. The private keys never leave the card, and every transaction requires the correct Card-PIN and physical NFC signing. Each X Card also has a unique encrypted hardware ID verified by the ELLIPAL App. After 10 incorrect Card-PIN attempts, the card automatically wipes its stored data. NFC only transmits encrypted transaction data and does not expose your private key. If you have any questions about the security design or would like help checking your setup, please contact us at cs@ellipal.com. Please do not send your Seed Phrase, Private Key, or full Passphrase.

Customer photo review of ELLIPAL X Card Cold Wallet

I was very excited when this promotion was advertised then was speechless watching this final knowing my team won this final hands down impressive the most touching thing was how the youngest player from Spain 🇪🇸 acknowledged his hero Mesi after the final whistle then to get my pimped out card in the post how special that i bumped into a Spanish traveler here in my country I told him about my card showed him a picture of it to how cool right

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Gary! We're delighted that the special-edition card and the story behind it made the experience so memorable for you. We hope you enjoy carrying and using your unique ELLIPAL X Card!

It's NFC compatible.

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Richmond! Yes, the ELLIPAL X Card uses NFC for convenient tap-to-sign transactions while keeping your private keys securely offline.

I have not even set it up. I feel like I would have to completely write up all the info about it and leave it somewhere my daughter could find it...should something happen to me. THAT SAID I would rather just invest on an exchange. I would like to return this please. Serene French

ELLIPAL X Card Cold Wallet

Store owner replied: Hi Serene, self-custody can be much simpler than it may seem. An ELLIPAL cold wallet keeps your private keys fully offline and gives you direct control of your assets, without relying on an exchange to hold them for you. You do not need to write down every detail about the wallet—just securely back up your seed phrase and any passphrase you choose to set. For inheritance, you can leave your daughter clear, secure instructions for accessing those backups when the time comes. Please remember that anyone with the recovery phrase and passphrase can control the assets, so keep them private, protected, and never share them with anyone, including ELLIPAL support. If you would like help setting everything up, please email cs@ellipal.com and our team will guide you.

My name is Frank, I am 64 years old technology illiterate. I began to purchase crypto on Coinbase but kept reading commentaries on social media sites how unsafe that might be. I started reading things about cold wallets being air gapped and only you have the seed phrase. I decided these two security measures were powerful, so I purchased the 2.0 ELLIPAL. I read the instructions and followed them and was scared to death at the point of transferring the crypto from Coinbase but thought no guts no glory. I did it all, super risky. It tells you to do a small portion first, but the reckless abandon in me just said it’s only money. It worked perfectly and I have done it multiple times now and feel at ease doing it. Thank you ELLIPAL I love your product. I’m now considering purchasing your thin wallets as well. If I can do it anyone can.

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you so much for sharing your story, Frank! Making that first transfer off an exchange takes courage, and you did a great job reading the instructions and seeing it through. You chose well, too: the ELLIPAL Titan 2.0 is fully air-gapped, so your private keys never touch the internet, and as long as your Seed Phrase is safely backed up, you're the only one in control of your crypto. For future transfers, we'd still recommend starting with a small test amount, just for extra peace of mind. If you decide to try our card wallet, the ELLIPAL X Card makes a great companion to your Titan. And as you said, if you can do it, anyone can. Welcome to self-custody!

I was nervous to transfer off the exchange but your website and You Tube videos helped a lot. Glad I bought your wallet

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Patricia! Moving off an exchange can feel nerve-racking the first time, so we're glad our website and YouTube videos helped. With your ELLIPAL X Card, you're now the one in full control of your crypto.

For a beginner it needs better instructions on how to use x card.

In the meantime, you can find our step-by-step X Card guide here: https://support.ellipal.com/x-card/create-a-new-wallet, and feel free to email cs@ellipal.com anytime if you need a hand.

It was very easy to set up

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks, Roy! Glad your ELLIPAL X Card setup went smoothly. Enjoy managing your crypto with confidence.

I'M NEW TO CRYPTO AND I HEAR THE WARNINGS ABOUT EXCHANGES AND KEYS AND SUCH THINGS. BUT ALSO ABOUT DESTINATION TAGS AND FRANKLY IM OVERWHELMED BY THE THOUGHT OF DOING SOMETHING WRONG AND LOSING IT ALL FOREVER. DO YOU OFFER A COURSE ONLINE OF STEP BY STEP HOW TO DO THIS FROM COINBASE TO ELLIPAL FOR EXAMPLE? AS PART OF THE PURCHASE OF THIS PRODUCT?

ELLIPAL X Card Cold Wallet

Store owner replied: Hi Ronald, those concerns are completely understandable, and taking your time is the right approach. Moving your crypto from Coinbase to a self-custody wallet means only you hold the keys, and a few careful habits make the process safe and simple: (1) In the ELLIPAL App, copy the receiving address of the coin you want to move: https://support.ellipal.com/x-card/view-receiving-addresses (2) In Coinbase, paste the address and select the same network. (3) For XRP, a Destination Tag is usually not required when sending to your own ELLIPAL wallet; if Coinbase asks for one, you can enter 0. (4) Send a small test amount first, then send the rest once it arrives. Most importantly, keep your Seed Phrase offline and never share it with anyone. If you'd like someone to walk you through it, email us at cs@ellipal.com and our team will be glad to guide you step by step.

Still trying to get it to work

ELLIPAL X Card Cold Wallet

Store owner replied: Hi Bryan, sorry the X Card isn't working as expected yet. You can follow our step-by-step setup guide here: https://support.ellipal.com/x-card/create-a-new-wallet. If you get stuck at any step, email us at cs@ellipal.com and let us know where it stops, and we'll help you get it running.

I love the airgap process

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks, Gary! We're glad you enjoy the process. With the ELLIPAL X Card, your private keys stay inside the card's secure chip and never touch the internet.

Awesome set!

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks, James! Enjoy your new ELLIPAL X Card set.

Very easy to setup. Would recommend to any new comer to crypto currency

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Roger! Making self-custody simple for people new to crypto is exactly what the ELLIPAL X Card is designed for, and we really appreciate the recommendation.

It was recommended to me. Glad to have Crypto off the exchange. However I needed help understanding setup and how to use it.

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks for the review, Patty! Moving your crypto off the exchange is a great step, since with a self-custody wallet you now hold your own keys. You can follow our step-by-step setup guide here: https://support.ellipal.com/x-card/create-a-new-wallet. If anything is still unclear, just email us at cs@ellipal.com and we'll walk you through it.

Simple and straight-forward. The way crypto should be!

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks, James! We couldn't agree more: keeping your crypto secure shouldn't be complicated. Enjoy your ELLIPAL X Card.

I don’t like the fact that the seed phrase is provided for you

ELLIPAL X Card Cold Wallet

Store owner replied: Thanks for the feedback, Chris. We'd like to clarify that the ELLIPAL X Card does not come with a preset Seed Phrase. It is generated randomly inside the card's secure chip when you create your wallet, and you can also choose to recover a wallet with your own existing Seed Phrase instead.

Excellent product. It lets you safely store your crypto. Very easy to use. If you don't have this wallet, you're at a great risk.

ELLIPAL X Card Cold Wallet

Store owner replied: Thank you, Eferem! We're glad the ELLIPAL X Card gives you both peace of mind and ease of use. With your private keys kept offline in the card's secure chip, you stay in full control of your crypto.

É bom saber.

Três coisas o diferenciam. Primeiro, sua carteira é criada em um Starter dedicado e offline, para que suas chaves sejam geradas sem nenhuma exposição à rede, com segurança desde o primeiro passo. Segundo, ele usa a frase-semente padrão BIP39, por isso funciona com as carteiras que você já usa, e sua seed continua sendo sua, sem ficar presa a um único aplicativo. Terceiro, ele se adapta à forma como você realmente armazena criptomoedas: use cada cartão como uma carteira separada ou vincule vários cartões a uma única carteira como backups, para que um único cartão não seja um ponto único de falha.

Não. O acesso exige seu Card-PIN, e não é possível recuperar o Card-PIN existente.

Após 10 tentativas incorretas, o cartão é redefinido para as configurações de fábrica e remove os dados da carteira armazenados nele. Suas criptomoedas permanecem na blockchain.

Um usuário com a Seed Phrase correta pode reinicializar o cartão com o ELLIPAL X Card Starter e definir um novo Card-PIN.

De forma alguma, ele foi feito para quem está usando pela primeira vez. Você ativa o cartão offline com o ELLIPAL X Card Starter, que cria sua frase-semente longe de qualquer celular ou computador, em cerca de 3 minutos. Depois disso, o aplicativo orienta você, o uso diário requer apenas um toque e, se você sabe usar o Apple Pay, pode usar o ELLIPAL X Card.

Não. A ELLIPAL X Card é uma carteira de autocustódia. Sua frase-semente e seu PIN são criados e mantidos por você e, durante a configuração offline, a ELLIPAL não tem como ver nem armazenar nenhum dos dois. Se algo acontecesse com os servidores da ELLIPAL, suas criptomoedas permaneceriam na blockchain e poderiam ser recuperadas em qualquer carteira compatível com BIP39.

O ELLIPAL X Card funciona com qualquer iPhone XS ou mais recente e qualquer telefone Android com NFC, portanto a maioria dos celulares dos últimos anos é compatível. Em termos de ativos, ele oferece suporte a mais de 10.000 tokens em mais de 45 blockchains, incluindo Bitcoin, Ethereum, Solana, XRP, Cardano, BNB Chain e Polygon.

Suas criptomoedas vivem na blockchain, sempre. O ELLIPAL X Card apenas armazena a chave privada que assina as transações, e ela nunca sai do chip seguro CC EAL6+. O firmware é bloqueado durante a fabricação de propósito: atualizações são um caminho de ataque comum para carteiras frias, então o ELLIPAL X Card simplesmente não tem atualizações.

Sim. A aproximação apenas alimenta o cartão via NFC e envia uma solicitação de assinatura. Sua chave privada e frase-semente nunca saem do chip seguro CC EAL6+, e nada retorna para o seu celular além da transação assinada. O cartão não tem bateria nem conexão própria com a internet, portanto não há nada que um invasor remoto possa acessar.
