NEXUS, which operates the blockchain ecosystem of South Korean app marketplace OneStore, signed a memorandum of understanding with U.S. digital-asset solutions firm The Tie and its institutional staking arm, Stakin by The Tie. Stakin will become a OneChain validator, while the companies cooperate on institutional participation, operating systems, risk management and transparency for network and staking information. OneChain data will be added to Staking Rewards, which covers more than 120 proof-of-stake assets and 90 staking providers. The Tie serves more than 500 institutional clients and, after acquiring Stakin in January, operates self-custodial staking infrastructure across more than 30 blockchain networks. NEXUS said the partnership would strengthen trust and support growth in the wider OneStore ecosystem.
