O que é o Tangem Ring?

Segurança e praticidade nem sempre andam juntas no universo das criptomoedas. O Tangem Ring, o primeiro hardware wallet em formato de anel do mundo, veio para mudar isso. Essa carteira física vestível permite acessar toda sua carteira de criptomoedas sem precisar de dispositivos volumosos, cabos ou até mesmo de um smartphone. Assim, você pode carregar seus ativos digitais com você e acessar mais de 6.000 moedas e uma gama completa de serviços cripto. 

Apresentamos o Tangem Ring no Cardano Summit em novembro de 2023. Desde então, ele passou por diversas melhorias de fabricação, testes rigorosos e ajustes de design — e agora já está disponível para pré-venda. Confira tudo que você precisa saber sobre o Tangem Ring neste momento.
 

    With the Tangem Ring, managing your cryptocurrencies is easy. You can send, receive, buy, or swap tokens with just a tap. This simple way of using digital assets is changing the game for crypto adoption, making it easier for everyone to get involved, no matter how tech-savvy they are. Uncompromising security   While the Tangem Ring prioritizes convenience, it doesn't cut corners on security. Built with a CC EAL6+ certified secure element—the same level of security used in Tangem Wallet cards—this ring acts as secure storage for your digital assets. The device's firmware cannot be upgraded, which is a unique feature in the hardware wallet. This significantly reduces the risk of remote hacks.

Tangem Rings will be available in sizes 8-13 US, corresponding to a diameter of 18.9mm to 22.2mm. Here are some simple methods to measure your ring size correctly. Method 1: With a string or piece of paper  Get a strip of paper, a piece of string, a ruler, and a pen. Cut the strip of paper to at least 10 cm long. Wrap the paper or string around the base of your finger. It should be snug but not too tight.  The paper should slide over your knuckle with a little resistance. Now mark the point where the paper or string overlaps itself.   Lay the paper flat and measure the length from the end to the marked point.  Record the measurement in millimeters and use it to find your ring size in our standard ring size chart. Method 2: Using an existing ring If you already have a ring that fits your favorite finger, you can use it to determine your size.  Remove the ring and place it on a piece of paper.   Trace the inner perimeter with a pen.    Then, measure the diameter of the circle in millimeters. This measurement should help you choose the right ring size. Method 3: Using a ring sizer You can get ring sizers online to determine your ring size. You can also visit a local jewelry store and ask the consultant to measure your size. So easy Method 4: Using templates You can also find online templates for measuring your ring size. Download and print them. For example, print a special ruler with a scale, cut it out, form a ring, and tighten it around your finger so the paper fits snugly. Many mobile apps can help you measure your ring size. Some tips for accurate measurement Measure your finger at the end of the day when it is largest. Make sure your finger is at a normal body temperature, as fingers can shrink or expand with cold or heat. If your knuckle is larger than the base of your finger, measure both and choose a size in between for a comfortable fit. For a more accurate result, repeat the measurement process a few times.   Why the Tangem Ring is superior to Tangem cards As a ring, it's the most portable hardware wallet ever created.
