Samsung has recently provided bitcoin support in its Keystore wallet, in addition to Ethereum and Klaytn digital currencies.
It was the first time in February when Samsung introduced the Galaxy S10 , a blockchain KeyStore-wallet, but until now, it only supported the ERC-20 Ethereum and Ethernet-based tokens.
Bitcoin’s vacancy, the first digital currency in terms of market size, has left many in the Keystream wallet frustrated by the popular currency. Many Bitcoin fans can now use the Keystore SDK wallet.
Samsung’s Keystore SDK blockchain allows Android apps and decentralized apps (Dapps) to interact directly with the KeyStore wallet blockchain network.
This helps buyers be able to add their blockchain addresses to the wallet, record blockchain transactions,
and keep track of their inventory. Samsung is now offering developers the beta version of the SDK in an application process.
Samsung hopes to release the original by the end of this year. In addition to the S10 Series handsets, the KeyStore wallet is also available on the new Note 4 and Note 4 Plus .
Samsung’s blockchain wallet is currently limit to several countries,
including Canada, Germany, South Korea, Spain, Switzerland, the United States and the United Kingdom. The possibility of developing countries covered in the coming months is likely.
The Korean giant is currently developing and developing a new blockchain based on the Ethereum currency, and may announce its official token in the near future.
Samsung supports Bitcoin within its key wallet
Samsung added support for Bitcoin cryptocurrency features in its blockchain keystore, according to updated information on the Samsung developer website. So Samsung supports Bitcoin within its key wallet
Samsung has integrated Bitcoin functionality on its blockchain smartphones; and the move comes months after the launch of the Galaxy S10 with the Blockchain Keystore portfolio.
The use of these keys is vital for many decentralized applications (dapps) as well as for storing cryptocurrency keys. Support is currently limited to S10 and Note 10 devices, including Galaxy S10e; Galaxy S10; S10 +; S10 5G; Note 10; and + Note10).
Samsung unveiled its blockchain keystore for the first time earlier this year, which currently includes 17 decentralized applications. Support is only available to customers in Canada; Germany; South Korea; Spain; Switzerland; the United States and the United Kingdom.
The information suggested that the company would start supporting Bitcoin, after the portfolio supported Ethereum. At the time of its release, the portfolio supported a small number of small ERC20 tokens that were mostly unhelpful in the real world.
There were reports earlier this year that Samsung was developing its own BlockChain network based on the main Ethereum network.

Samsung Blockchain Keystore SDK allows your Android app, DApp to directly communicate with Samsung Blockchain Keystore, a preloaded feature on selected Galaxy devices. By integrating Samsung Blockchain Keystore SDK into your Android app, you can leverage the following:
Get Blockchain address to link to the Samsung Blockchain Keystore
Developers can link user’s Blockchain address like a user’s account. With the address returned from Samsung Blockchain Keystore, developers can check and show users how much cryptocurrency balance is in the account as well as view the transaction history. Samsung Blockchain Keystore supports BIP-39 compatible HD (Hierarchical Deterministic) Wallet – a standard tree structure, represented by derivation paths. Developers can use Samsung Blockchain Keystore API to enter an HD Path and Samsung Blockchain Keystore will derive the address from the public key that corresponds to the HD Path. So developers can simply receive and utilize the address in return.
Sign a cryptocurrency transaction
Developers can use Samsung Blockchain Keystore API to request the Samsung Blockchain Keystore to sign a cryptocurrency transaction. Samsung Blockchain Keystore will show the requested transaction to the user on a secure screen called, Trusted User Interface (TUI), executed in the Trusted Execution Environment (TEE). Once the user checks the transaction information and confirms the transaction with a PIN or a biometric authentication like Fingerprint, Samsung Blockchain Keystore will sign the transaction with a private key derived from the Master Seed stored in the Secure File system.
Check Samsung Blockchain Keystore status
Developers can use an API provided by the Samsung Blockchain Keystore to check if a user is ready to use Samsung Blockchain Keystore. If the user has not created a wallet yet, developers can direct the user to create a new wallet to leverage Samsung Blockchain Keystore features. When a user chooses “Create a Wallet”, it implies that a Master Seed is created and stored safely in the Secure File system. The user can also “Import a Wallet” by entering mnemonic words created from a different wallet, thereby restoring the Master Seed. Samsung Blockchain will check the existence of a Master Seed and return the status value.
