Samsung Blockchain Keystore is the security engine behind every S20 wallet address. It stores your private keys in a dedicated secure processor completely isolated from Android, giving you hardware-grade protection without needing a separate hardware wallet.

What Is Samsung Blockchain Keystore?

Samsung Blockchain Keystore (SBK) is a dedicated security area on Galaxy S20 devices that stores your cryptocurrency private keys. It uses a secure processor that is physically and logically isolated from the main Android operating system. Samsung Knox — the same defense-grade security technology used in Samsung devices certified for government and military use — powers the Blockchain Keystore.

How Keystore Protects Your S20 Wallet Address

When you use your S20 wallet address to sign a transaction, the Blockchain Keystore generates a cryptographic signature inside the secure enclave without ever exposing the private key to the Android OS. This means even if malware infects your phone, it cannot access or steal your private keys.

The Samsung Blockchain Keystore SDK allows developers to build decentralized apps that can request signatures from Keystore, enabling secure blockchain interactions while keeping private keys protected at all times. Available on all Galaxy S20, S20+, S20 Ultra, and S20 Fan Edition 5G devices.
