Swiss crypto bank AMINA has launched the world's first compliant institutional staking service for POL, the native token of the Polygon blockchain. In collaboration with the Polygon Foundation, AMINA offers its clients, including asset management firms and corporate treasuries, the opportunity to earn up to 15% in staking rewards. This initiative not only enhances AMINA's existing POL custody and trading services but also provides a compliant avenue for institutions to engage in blockchain network security. Polygon Labs CEO highlighted this as a significant shift towards deeper institutional involvement in the blockchain ecosystem.
