TBD, a bitcoin developer-focused entity owned by Jack Dorsey’s Block, has partnered with Yellow Card, an Africa-focused cryptocurrency exchange platform, to launch a fiat on and off-ramp that enables payments in 16 African countries through Bitcoin rails. The new platform aims to make cross-border payments more affordable, accessible, and compliant.

For recipients living in countries with hyperinflation, the platform can be used as a place to store BTC or stablecoins.

The partnership is expected to advance Block's empowerment via breaking down the barriers to financial access across the Global South.
