HashKey MENA, the Aptos Foundation and African payments startup Daya signed a Corridor Pilot Agreement on June 4 to build regulated B2B stablecoin (digital tokens designed to maintain stable value) settlement infrastructure between the UAE, the broader MENA region and African markets, initially focusing on Nigeria and the naira. The initiative targets a market where average fees for $200 remittances to Sub-Saharan Africa are 7.9%, while informal channels fill gaps left by formal finance. Research cited around the announcement found that 79% of users in leading African markets hold stablecoins, and that Africa received more than $205 billion in on-chain stablecoin value from July 2024 to June 2025. HashKey MENA will provide regulated fiat-to-stablecoin ramps under its Dubai VARA (Dubai virtual-assets regulator) license, Daya will supply smart routing and local-currency off-ramps, and Aptos will serve as the Layer 1 settlement blockchain (base network for processing transactions). Stablecoin activity on Aptos had surpassed $1.9 billion, up from $649 million earlier in 2025. The pilot is designed to test whether compliant enterprise infrastructure can support corporate settlements as it expands into Nigeria, where crypto activity is substantial but regulation has shifted between accommodation and restriction.
