Tether, the largest company in the digital asset industry, is working with Shiga to bring self-custodial financial products, in which users retain control of their assets, to individuals, businesses and institutions across Africa and the Gulf Cooperation Council. The initiative is built on Tether’s open-source Wallet Development Kit (WDK) and follows Tether’s strategic investment in Shiga in 2025. ENTA will allow individuals, high-net-worth users and businesses to fund wallets with local currency, U.S. dollars or Bitcoin and hold or transfer USD₮, Bitcoin and XAU₮. Pulse will help banks, fintech companies and other institutions create digital asset products for payment corridors, treasury operations and settlement flows. The products use WDK, which supports multiple blockchain networks through one integration and includes USDT0 technology, DeFi primitives and cross-chain interoperability. Tether said the initiative addresses currency volatility and expensive remittances, with the average cost of sending money to Sub-Saharan Africa reaching 8.46% in 2025. Shiga is completing the final approval stage for a Digital Asset Intermediary licence in Nigeria, which would permit regulated digital asset dealing, broking and custody services if approved.
