Sui is now operating as settlement infrastructure for African payments company Daya, enabling supported stablecoin transfers without requiring customers to maintain SUI for blockchain transaction fees. The integration is already live in Nigeria across Daya Business, Daya Pro and Daya APIs, extending the network into cross-border payments, liquidity management and treasury rebalancing rather than positioning it primarily as a venue for speculative trading.
According to Daya’s official announcement, the company added Sui as one of the blockchain rails used to settle stablecoin transfers. Businesses can move supported stablecoins such as USDC without first acquiring or holding the network’s native token solely to pay gas. Daya says network fees on these Sui transfers are zero, although its own customer fees remain unchanged.
Sui Removes the Second-Token Requirement
The operational benefit centers on treasury management. On many blockchain networks, a business moving dollar-denominated stablecoins must also maintain a balance of the network’s native token to cover transaction fees. Daya’s Sui integration removes that second-token requirement from supported payment flows, reducing one additional asset and balance that corporate treasury teams would otherwise need to acquire, monitor and replenish.
Sui’s own announcement says the rail supports Daya’s payments, remittance, liquidity and developer-facing products. Daya Business provides payment and treasury services, Daya Pro serves liquidity and foreign-exchange workflows, while Daya APIs expose the infrastructure to fintechs and other platforms. Sui therefore sits below several customer-facing products as settlement infrastructure rather than functioning as a standalone payment application.
The integration should also not be interpreted as Daya moving all of its payments onto Sui. Daya explicitly says it settles across several networks and continues to determine how each payment is routed while sourcing the required liquidity itself. Sui becomes another available execution rail inside Daya’s broader payment stack, with the company retaining control over which network handles an individual transaction.
Nigeria Becomes the First Live Market
Nigeria is the first confirmed market where the Sui integration is operational. Sui Foundation says Daya plans to extend the model into South Africa, Ghana and Kenya as additional local-currency rails become available. Those markets remain part of the expansion roadmap rather than confirmed live deployments, making Nigeria the current reference point for assessing real usage of the integration.
The launch also provides a more precise way to interpret “gasless payments.” Removing blockchain gas can simplify the user experience and eliminate native-token management, but foreign exchange, liquidity, conversion, payout and Daya service costs remain separate economic components. The integration reduces one source of payment friction rather than demonstrating that cross-border settlement itself has become cost-free.
The next meaningful evidence will come from production activity rather than infrastructure availability alone. Stablecoin settlement volumes, treasury rebalancing activity and the activation of local-currency routes in South Africa, Ghana and Kenya will show whether Sui develops into a material rail for Daya’s African payment flows. For now, the confirmed development is narrower but operational: businesses using supported Daya products in Nigeria can settle eligible stablecoin transfers through Sui without separately managing SUI for network fees.
