Swiss crypto payments startup, Holyheld, has secured funding from a range of investors including Toyota Ventures and Polygon to accelerate its BRRR protocol. The protocol aims to connect public blockchain networks, traditional payment, and card networks to create a global layer of real-time payments. Holyheld's app, which uses the BRRR protocol, offers a cash account with a debit card available to residents of 30 European countries, allowing users to connect any self-custody wallet and use their cryptocurrency for daily purchases. The funding will allow Holyheld to expand the protocol to more clients and payment networks globally.
