SBI Group Expands Crypto Ecosystem with Strategic Investment
SBI Group, established in 1999 and headquartered in Tokyo, is one of Japan’s most influential financial services conglomerates. Over the past few years, it has actively pursued blockchain and cryptocurrency ventures, investing across multiple sectors including crypto exchanges, mining operations, custody solutions, and decentralized finance platforms.
In a recent announcement, SBI revealed its acquisition of a major equity stake—specifically 40%—in CoolbitX, the innovator behind the CoolWallet hardware wallet. This move underscores SBI’s broader strategy to integrate cutting-edge security technologies into its expanding digital asset infrastructure.
The investment comes amid increasing concerns over exchange hacks and private key vulnerabilities. By partnering with a proven hardware wallet provider, SBI aims to offer institutional and retail investors alike a more secure way to manage their digital assets.
CoolbitX and the Evolution of Hardware Wallets
Founded in 2015, CoolbitX introduced the CoolWallet—a credit card-sized hardware wallet that combines portability with military-grade security. Unlike traditional bulky hardware devices, the CoolWallet uses NFC (Near Field Communication) and Bluetooth technology to connect seamlessly with iOS and Android smartphones.
Users can securely store and transact popular cryptocurrencies such as Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), and Ripple (XRP) without exposing their private keys to potentially compromised environments. The device features an embedded secure element chip, ensuring that private keys never leave the protected hardware environment.
Michael Ou, CEO and co-founder of CoolbitX, emphasized the product's dual focus on convenience and security:
“Our wallet is designed to be as easy to carry as a credit card, yet far more secure than software wallets or exchanges.”
This balance between usability and protection has made CoolWallet a preferred choice among security-conscious crypto holders—especially in regions like Asia, where mobile-first financial behavior is dominant.
Why Security Is at the Core of SBI’s Crypto Strategy
For SBI Group, security isn’t just a feature—it’s a foundational principle. As cyberattacks on centralized exchanges continue to rise globally, the need for decentralized, user-controlled storage solutions has never been greater.
By acquiring a significant stake in CoolbitX, SBI signals its intent to prioritize cold storage technology and private key management within its wider fintech offerings. The collaboration will likely lead to enhanced product development, potential integration with SBI’s existing financial services, and expanded market reach across Japan and Southeast Asia.
“Beyond internal risk management systems,” SBI stated in its official release, “we are committed to adopting advanced external technologies to safeguard our clients’ digital assets.”
Future initiatives may include co-branded wallets, institutional-grade custody solutions, or even integration with national digital ID frameworks—leveraging CoolbitX’s proven security architecture.

Building a Resilient Cryptocurrency Ecosystem
SBI Group’s investment in CoolbitX is not an isolated event. It forms part of a larger vision to construct a self-sustaining crypto ecosystem that spans trading, staking, lending, custody, and payments.
Over the past year, SBI has invested in various blockchain ventures—from crypto hedge funds and derivatives platforms to mining infrastructure and regulatory-compliant exchanges. The CoolbitX acquisition adds a crucial layer: secure end-user access.
With growing retail and institutional adoption of digital currencies, having a reliable hardware solution ensures that users maintain full control over their assets—a core tenet of decentralization.
Moreover, this partnership could pave the way for wider adoption of hardware wallets in traditional banking channels. Imagine future scenarios where banks issue crypto-enabled cards similar to CoolWallets as part of their digital banking packages—a seamless bridge between fiat and crypto economies.
