PANews reported on March 24 that the Solana Foundation launched the Solana Developer Platform ( SDP ) for institutions, with Mastercard , Western Union , and Worldpay among the early adopters. Mastercard will leverage SDP to enable direct settlement of stablecoins on networks like Solana , expanding its stablecoin business. SDP offers three main API modules: an issuance module supporting the issuance of compliant stablecoins and deposit-type tokens; a payment module orchestrating on-chain / off-chain fund flows and B2B payments between fiat currency and stablecoins; and a transaction module supporting atomic swaps, treasuries, and foreign exchange. Western Union stated that it will use SDP to add an on-chain API layer to its existing cross-border remittance network, promoting compliant and scalable on-chain cross-border payment scenarios.
