Solana Foundation Launches Enterprise Developer Platform as Worldpay and Western Union Sign On

The Solana Foundation launched the Solana Developer Platform (SDP) on March 24, bringing together infrastructure from more than 20 providers (node operators, custodians, compliance tools, and payment ramps) into a single API interface designed for banks and payments companies. Worldpay and Western Union are among the first enterprises deploying it, targeting merchant settlement and cross-border payment infrastructure respectively.

The platform addresses a friction that has kept legacy financial institutions at arm's length from blockchain infrastructure: integrating custody, compliance, on-ramps, and node access separately before any product can go live. SDP packages those components into a unified developer interface, allowing enterprise teams to build on Solana without blockchain-native engineering depth.

What Worldpay and Western Union Are Building

Worldpay is deploying SDP to give merchants access to onchain settlement and tokenized assets, using the platform's payments module to route settlement flows directly on Solana. The company described the capability as offering "merchants seamless access to onchain settlement and tokenized assets."

Western Union is using SDP's payments and issuance modules to build what the company calls an "API-driven, on-chain layer that can orchestrate fiat and stablecoin flows end-to-end." Malcolm Clarke of Western Union framed the move as additive rather than disruptive: the platform "expands its network's capabilities rather than replacing them." Western Union's core business is moving money across borders, and SDP provides a stablecoin layer to do that on Solana infrastructure.

Mastercard, which launched always-on stablecoin settlement across eight blockchains including Solana earlier this year, is also an early SDP user. Raj Dhamodharan, the company's Executive VP of Blockchain and Digital Assets, said Mastercard is "helping enable direct stablecoin settlement for customers on select blockchain networks, beginning with Solana." His broader framing: "The next phase of digital asset innovation will be defined by practical use cases that integrate seamlessly with existing financial systems."

SDP Modules and Infrastructure Partners

SDP is structured around three modules. Two are live at launch: an issuance module for tokenized deposits, GENIUS Act-compliant stablecoins, and real-world assets; and a payments module for fiat and stablecoin flow orchestration covering on-ramps, off-ramps, and onchain B2B, B2C, and P2P transactions. A third module for atomic swaps, vaults, and onchain foreign exchange is scheduled for later in 2026.

The 20+ infrastructure partners integrated at launch span four categories: node infrastructure (Alchemy, Helius, QuickNode, Triton), wallets and custody (Anchorage Digital, BitGo, Coinbase, Crossmint, Dfns, Dynamic, Fireblocks, Paxos, Privy, Turnkey), compliance (Chainalysis, Elliptic, Range, TRM), and payment ramps (Bridge, BVNK, Lightspark, Modern Treasury, MoonPay). Both live modules launched in sandbox on Solana's devnet; full production rollout is scheduled throughout 2026.

Stablecoin Adoption Context and Solana's RWA Market Share

The SDP launch arrives as stablecoin adoption on Solana accelerates across institutional use cases. When Circle minted $500 million in USDC on Solana in June, Solana's share of global USDC supply hit 10.3%, its highest recorded level, while Ethereum's share contracted in the same week. Visa and Mastercard were identified in that coverage as structural institutional demand drivers.

Solana's share of the real-world asset tokenization market currently sits at roughly 6.3% against a global market of approximately $328 billion, per RWA.xyz data, compared with Ethereum's share above 50%. The SDP is a deliberate infrastructure bet on closing that gap through ease of enterprise integration.

Catherine Gu of the Solana Foundation said the early interest from Worldpay, Western Union, and Mastercard "signals strong demand." What distinguishes their participation from prior institutional announcements is specificity: three companies with distinct, large-scale payments operations are deploying SDP for different operational functions (merchant settlement, cross-border remittances, and card network stablecoin settlement) rather than running separate proofs of concept.

The trading module, scheduled for later this year, will extend the platform's live capabilities to atomic swaps, vaults, and onchain FX.
