Solana launches SDP, an API-based development platform for institutions.

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.
