A hardware wallet is a cryptocurrency wallet which stores the user's private keys (critical piece of information used to authorise outgoing transactions on the blockchain network) in a secure hardware device. The main principle behind hardware wallets is to provide full isolation between the private keys and your easy-to-hack computer or smartphone.

Yes. You cannot access your cryptocurrency without your private keys and an interface that accesses a blockchain. All wallets can store keys, but only hot wallets can access the blockchain, so it's important to keep your keys off your hot wallet until you need them.

Personal favorite multi currency wallet. Very useful Coin Swapping exchange, exchange any coin to other coin, I normally used it for swapping my high value coins against small value coins...

A cryptocurrency wallet is a device,[1] physical medium,[2] program or an online service which stores the public and/or private keys[3] for cryptocurrency transactions. In addition to this basic function of storing the keys, a cryptocurrency wallet more often offers the functionality of encrypting and/or signing information.[4] Signing can for example result in executing a smart contract, a cryptocurrency transaction (see "bitcoin transaction" image), identification, or legally signing a 'document' (see "application form" image).[5]

In March 2022, approximately 600 crypto exchanges globally facilitated digital asset trading, including Binance, Coinbase, Crypto.com, Gemini, GMO Coin, Huobi, eToro, Kraken, Robinhood.[9][4] Asside from cryptocurrency exchanges, consumers had an option to utilize cryptocurrency wallets such as Ledger, Trezor, MetaMask and others for the secure storage and management of digital assets.

The first wallet program, simply named Bitcoin, and sometimes referred to as the Satoshi client, was released in 2009 by Satoshi Nakamoto as open-source software.[10] In version 0.5 the client moved from the wxWidgets user interface toolkit to Qt, and the whole bundle was referred to as Bitcoin-Qt.[11] After the release of version 0.9, the software bundle was renamed Bitcoin Core to distinguish itself from the underlying network.[12][13] Bitcoin Core is, perhaps, the best known implementation or client. Forks of Bitcoin Core exist, such as Bitcoin XT, Bitcoin Unlimited,[14] and Parity Bitcoin.[15]

Third-party internet services called online wallets or webwallets offer similar functionality but may be easier to use. In this case, credentials to access funds are stored with the online wallet provider rather than on the user's hardware.[18] As a result, the user must have complete trust in the online wallet provider. A malicious provider or a breach in server security may cause entrusted bitcoins to be stolen. An example of such a security breach occurred with Mt. Gox in 2011.[19]

A cryptocurrency wallet works by a theoretical or random number being generated and used with a length that depends on the algorithm size of the cryptocurrency's technology requirements. The number is converted to a private key using the specific requirements of the cryptocurrency cryptography algorithm requirement. A public key is then generated from the private key using whichever cryptographic algorithm is required. The private key is used by the owner to access and send cryptocurrency and is private to the owner, whereas the public key is to be shared to any third party to receive cryptocurrency.[28]

Collision (two or more wallets having the same private key) is theoretically possible, since keys can be generated without being used for transactions, and are therefore offline until recorded in the blockchain ledger. However, this possibility is effectively negated because the theoretical probability of two or more private keys being the same is extremely low. The number of possible wallets and thus private keys is extremely high,[4][29][30] so duplicating or hacking a certain key would be inconceivable.[31][32]

In modern convention a seed phrase is now utilised which is a random 12 to 24 (or even greater) list of dictionary words which is an unencrypted form of the private key. (Words are easier to memorize than numerals). When online, exchange and hardware wallets are generated using random numbers, and the user is asked to supply a seed phrase. If the wallet is misplaced, damaged or compromised, the seed phrase can be used to re-access the wallet and associated keys and cryptocurrency in toto.[33] 006ab0faaa
