About the project, we need power for

In cooperation with one of our clients, who is a financial technology company, we develop leading software solutions for asset tokenization. The clients benefit from all building blocks, services, and licenses needed to issue tokenized securities and manage decentralized security registries. The presence of a high number of intermediaries like banks and custodians leads to high transaction costs on the capital market. We use Distributed Ledger Technology to provide a global capital market 2.0 that works for everyone without intermediaries. We’re on this mission to create a more open access to capital and therefore more thriving ideas coming to life.
