What is COLDCARD?

Physical Security measures are enhanced through the use of a specialized chip that protects your secret seed words and ensures that sensitive information is securely stored. The software is open source, giving users the flexibility to compile it independently if desired. This hardware wallet uniquely allows for a completely offline experience, supporting all processes from seed generation to the approval of transactions without needing an internet connection. It features native support for PSBT (BIP174), which significantly boosts its usability. With a full-sized numeric keypad, entering your PIN is made easy and efficient. The design is minimalistic and straightforward, avoiding excessive packaging with unnecessary boxes or cables. A vibrant 128x64 pixel OLED display shows all crucial transaction information clearly. To keep your private key secure, a dedicated crypto security chip is employed, isolating it from the main microcontroller's flash storage. Proudly crafted in Toronto, Canada, it boasts a reliable supply chain, reinforced by a tamper-evident bag that is numbered, with this information logged within the device. Moreover, it includes an integrated MicroSD card slot for backup and data storage, allowing for completely offline transaction signing through sneakernet, which ensures that your crypto assets are well-protected and remain out of reach from potential threats. This combination of features makes it an exceptional choice for anyone prioritizing security in their cryptocurrency transactions.

What is Bither?

The Bither wallet offers both cold and hot modes, facilitating the use of Bitcoin with the same ease as cash or credit cards. In its cold mode, the Bither Cold Wallet operates offline and includes features such as mobile device backup, protection of private keys with a digital password, monitoring of network status in real-time (covering Wifi, 3G, and Bluetooth), security checks for private keys, the capability to sign unsigned transactions from the hot wallet, and automated backup and recovery options. Conversely, the Bither Hot Wallet connects online, allowing users to conveniently monitor their Bitcoin holdings through the Watch Only mode, prepare unsigned transactions for addresses tracked in this mode, and utilize private keys for enhanced ease of use. Users may store a small quantity of Bitcoin in this wallet type for daily transactions, enjoying its decentralized and peer-to-peer attributes that eliminate the need for registration or login. Furthermore, the hot wallet keeps users informed with real-time pricing updates from leading Bitcoin exchanges and system alerts for any new transactions, ensuring they remain well-informed at all times. This combination of functionalities not only heightens security but also improves accessibility for those engaging with Bitcoin. Ultimately, Bither is designed to cater to the diverse needs of its users, blending security with user-friendliness effectively.
