The European Union is supporting strategic trade corridors around Africa, linking key ports to economies deep inside the continent, and creating new infrastructure for goods to move between countries in Africa and Europe.
The financial infrastructure supporting those routes could also become an important part of the growth, particularly as businesses move between currencies and payment systems across multiple jurisdictions.
As part of its Global Gateway strategy, the EU has identified 12 strategic corridors, including the route from Douala and Kribi to Kampala that connects Cameroon, the Central African Republic, the Republic of Congo and Uganda.
Another route runs from Cairo through Khartoum and Juba to Kampala, while the Mombasa to Kisangani corridor connects Kenya, Uganda and Rwanda.
The corridors are meant to facilitate trade and mobility within Africa and between Africa and Europe. The wider Africa-Europe Investment Package also includes digital connectivity and regulatory work alongside transport infrastructure, with the EU targeting the integration of African and European transport networks by 2030.
For businesses using these routes, however, moving a shipment from one country to another is only part of the transaction because the payment still has to be transferred across different currencies, banking systems and regulatory jurisdictions.
The Currency Problem Behind the Corridors
Take a Ugandan company buying goods from Cameroon, whose transaction would involve the Ugandan shilling and the Central African CFA franc, while a European buyer dealing with the same company could bring the euro or US dollar into the mix.
A European buyer could convert euros into USDC, send it to Uganda, and have it converted into UGX for the exporter. But that only works smoothly if there is enough trading activity in pairs such as EUR/USDC and USDC/UGX.
If there aren’t enough buyers and sellers for USDC and UGX, a large payment could take longer to process or get a worse exchange rate.
The more currencies a corridor connects, the more liquidity is needed at each point. Stablecoins can simplify the number of currency conversions involved. However, they still need strong local currency liquidity to make the final conversion into and out of currencies such as the Ugandan shilling.
The Regulatory Layer Behind the Payment Infrastructure
The regulatory rules on each side of the corridor will determine which firms can issue, hold, exchange, and transfer the stablecoin.
In Europe, MiCA covers stablecoins, their issuers and the crypto asset service providers handling them. A European business using a stablecoin for an African payment would therefore need to work with authorized providers that meet requirements around areas such as governance, reserves, custody and operations.
On the other side, Uganda is still developing its framework. In 2026, the Bank of Uganda said it would conduct and participate in a Regulatory Impact Assessment to support a comprehensive framework for virtual assets and virtual asset service providers.
As a result, a European company may already have to use a regulated crypto provider to convert euros into a stablecoin, while the Ugandan side would need licensed or otherwise permitted providers to convert that asset into UGX and handle the payment. Until Uganda’s rules are finalized, the firms providing that local conversion and settlement layer face more regulatory uncertainty.
That makes the regulatory status of the companies around a stablecoin as important as the token itself. An international payment can involve an issuer, exchange, custodian, and payment provider, with each potentially subject to different rules depending on the jurisdiction.
Doxa Is Building Around the Kampala Side
Doxa is a Kampala-based project developing DOXAUSD, which it describes as a fully on-chain, USD-backed stablecoin for payments, savings, remittances and decentralised finance. Its ecosystem also includes DPay, which, according to the firm’s website, is a merchant payment system.
Founder Kizza Fredrich Kibalama has said the project was made to introduce digital dollar infrastructure in Uganda. In an earlier application to MIT Solve, he also identified regulation as one of the barriers to scaling it.
For DOXAUSD to support cross-border payments, users would need a way to move between the stablecoin and UGX. A European transaction could involve EUR to DOXAUSD on the European side, followed by DOXAUSD to UGX in Uganda. That requires sufficient liquidity in both pairs, along with providers that can handle conversion and payouts. Doxa would also need compliant on and off-ramps connecting the stablecoin to regulated institutions and local payment networks.
Its relevance to the Kampala side of the corridor therefore depends on whether those liquidity, payment and regulatory connections develop alongside the stablecoin.
Building the Financial Layer Alongside the Trade Routes
The EU’s corridor strategy covers more than roads, ports and railways, with its Africa-Europe Investment Package also including digital infrastructure, regional economic integration and regulatory harmonization to support trade across multiple countries.
To make this work, the financial system also has to support the movement of goods. A shipment travelling from Douala to Kampala can pass through several jurisdictions before reaching its buyer, with payments moving between businesses that use different currencies and banking systems.
A functioning payment layer would require liquidity providers for local currency pairs, regulated on and off ramps, banks or payment institutions able to receive and settle funds, and compliance systems that work across jurisdictions.
Stablecoins could be used as a common settlement asset across these transactions as they reduce the number of currency conversions involved and allow payments to move through digital networks without relying entirely on banking relationships. Greater use of these corridors could therefore create additional demand for cross-border stablecoin payments.
