African payments infrastructure company Daya has integrated Sui as a settlement rail for stablecoin transfers, allowing businesses to move supported digital dollars without holding SUI to cover blockchain gas fees. The integration is already live in Nigeria across Daya Business, Daya Pro and Daya APIs, extending Sui into cross-border payments, liquidity management and treasury rebalancing for Daya customers.
According to the official Sui announcement, the deployment is intended to remove the operational requirement to maintain a separate native-token balance solely for network fees. Businesses can send stablecoins through the Sui rail without acquiring or managing SUI as a second treasury asset, while Daya continues handling payment routing and liquidity behind the service.
Sui Becomes Another Settlement Rail Inside Daya
Daya’s own documentation describes the integration as infrastructure underneath its existing products rather than a replacement for its broader payment stack. The company still chooses how each transaction is routed and sources the required liquidity, with Sui operating alongside other supported blockchain networks. Which settlement rail handles an individual payment remains a routing decision made by Daya rather than by the end user.
The company specifically highlights USDC as an example of the user experience, saying businesses can send it without first buying or holding a network token. Daya describes supported stablecoin transfers on Sui as carrying no network fee. That zero-gas experience applies to the blockchain transaction cost, however, and does not mean Daya itself has eliminated its commercial fees. The company explicitly states that its existing customer fees remain unchanged.
Sui Foundation says the integration also supports treasury rebalancing and cross-border payments, potentially reducing one operational burden for businesses managing stablecoin balances across networks. The practical benefit is simplified fee management rather than evidence that overall cross-border payment costs have fallen to zero, since foreign exchange, liquidity, payout and service charges remain separate from blockchain gas.
Nigeria Launch Sets Up Wider African Expansion
Nigeria is the first active market for the integration, where Sui says Daya holds the relevant licenses. The companies plan to extend the model into South Africa, Ghana and Kenya as Daya activates additional local-currency rails. Those three markets remain planned expansions rather than locations where the Sui settlement integration is already confirmed live.
The deployment spans Daya’s three principal infrastructure products. Daya Business covers global payments, USD access, treasury controls and reconciliation; Daya Pro serves liquidity and foreign-exchange workflows; and Daya APIs expose the infrastructure to fintechs, platforms and enterprise developers. Sui therefore operates below several customer-facing services as settlement infrastructure rather than as a standalone consumer payment product.
The next measurable milestone will be expansion beyond Nigeria and evidence of actual settlement activity through the new rail. Transaction volume, stablecoin flows and activation of local-currency routes in South Africa, Ghana and Kenya will provide clearer evidence of adoption than the integration announcement alone. For now, the confirmed development is narrower but operational: Daya has made Sui a live settlement option that removes the need for its users to maintain SUI solely to pay stablecoin transfer fees.
