Coinbase, Mastercard, Shopify, Stripe and Visa will become founding partners of Open Standard, investing in the company and providing more than $1 billion in initial launch liquidity for Open USD (OUSD), a stablecoin designed for banking, cross-border payments, settlement and institutional trading. Zach Abrams has been appointed full-time CEO of Open Standard after previously leading both Open Standard and Bridge. Abrams earlier led product teams at Square, Coinbase and Brex before founding Bridge, a stablecoin orchestration platform. The partners will receive equity based on platform activity and supply generation after OUSD launches, while a founder-led board will represent shareholders.
