The deal pairs Yellow Card’s stablecoin rails across 34 countries with embedded wallet infrastructure, as Visa, Mastercard and PayPal already use Yellow Card for cross-border flows
Yellow Card, a licensed stablecoin infrastructure provider operating in 34 countries including 20 in Africa, has selected Turnkey to provide embedded wallet infrastructure for its stablecoin payment rails.
The partnership addresses a longstanding adoption barrier: stablecoins offer faster, cheaper settlement than correspondent banking, but using them has typically required end users to manage crypto wallets, seed phrases and private keys, friction that undermines the simplicity stablecoins are meant to deliver. Under the new arrangement, wallets are provisioned automatically in the background when a user signs up for an application built on Yellow Card. Users authenticate through familiar methods like email or passkeys, while Turnkey handles key generation and secure signing, and Yellow Card manages on/off-ramps, FX conversion and compliance.
Yellow Card’s existing infrastructure already underpins stablecoin activity for several major payment networks. Visa uses it for treasury operations and liquidity management in emerging markets. Mastercard partnered with Yellow Card in May 2026 to pilot stablecoin payments across Eastern Europe, the Middle East and Africa, covering remittances, B2B settlement and treasury flows. PayPal has selected Yellow Card as a Xoom disbursement partner for its PYUSD stablecoin, enabling cross-border transfers into local bank and mobile money accounts across Africa.
For Yellow Card’s banking and fintech clients, the addition of embedded wallets via Turnkey lowers the integration burden considerably, consolidating key management, authentication and custody controls into a single API rather than requiring separate infrastructure builds. The practical effect is that stablecoin-based cross-border payments, which currently average 6.36% in cost and can take days to settle through correspondent banking, can be offered to end users through an experience that looks like any other payment app, with the underlying stablecoin infrastructure entirely invisible.
