Coincheck Group shares rose Tuesday after Japanese telecom provider KDDI agreed to invest $65 million in the company and to form a partnership aimed at bringing digital-asset services to a broader audience in Japan.

Shares rose 25% to $2.19.

The Amsterdam-based crypto platform agreed to issue about 28.5 million new shares to KDDI at $2.28 each, giving the telecom a 14.9% stake in Coincheck as well as the right to nominate one board member.

Alongside the investment, Coincheck's Japanese unit and KDDI agreed to enter a business alliance focused on expanding the country's digital-asset market throughjoint initiatives including mutual customer referrals and revenue-sharing.

The companies plan to bring together KDDI's distribution reach and consumer interfaces with Coincheck's crypto-asset infrastructure to streamline onboarding, widen access to digital assets and build more everyday use cases across KDDI's ecosystem.
