MoneyGram has become a validator on Solana SOL$92.12-2.9%, joining an institutional payments cohort that includes Mastercard, Western Union, and Worldpay on the Solana Developer Platform, according to reporting by The Block on June 22, 2026.
The move makes Solana the third public blockchain on which the Dallas-based remittance company operates as an official validator. MoneyGram previously ran validators on Tempo and the Cardano privacy sidechain Midnight Network, signaling a consistent strategy of using validator participation as a mechanism for deeper infrastructure integration rather than passive observation.
What the Validator Role Involves
Validators on Solana process transaction blocks, vote on the canonical chain, and earn SOL staking rewards in proportion to their uptime and stake weight. CEO and chairman Anthony Soohoo told The Block that the validator role enables MoneyGram to "stake SOL, process transaction blocks, and contribute to the security and performance" of the network.
MoneyGram serves more than 60 million customers globally, per The Block. The company's existing payments infrastructure, spanning money transfer corridors, cash access points, and compliance frameworks built across decades of cross-border operations, gives it operational context that most validator entrants lack.
The Solana Developer Platform
The Solana Developer Platform (SDP) is an API-powered institutional toolkit launched by the Solana Foundation that aggregates protocol infrastructure so enterprises can build financial products without standing up blockchain nodes from scratch. Its three core modules cover issuance (tokenized deposits, GENIUS-compliant stablecoins, real-world assets), payments (fiat and stablecoin on/off-ramp and on-chain flows), and trading (atomic swaps and on-chain FX, launching later in 2026).
Membership gives MoneyGram access to those development tools alongside the platform's 20-plus infrastructure partners spanning node providers, custodial wallets, compliance vendors, and on/off-ramp services. Early enterprise users of the SDP include Mastercard, which is using the platform for stablecoin settlement; Worldpay for merchant payments; and Western Union for cross-border payment flows.
The addition of MoneyGram is notable because the company's core business, retail remittance to unbanked and underbanked populations across more than 200 countries, maps directly onto the stablecoin cross-border payment use case the SDP is designed to enable. Solana Compass reported earlier this week that Toss Bank signed an MOU with the Solana Foundation for a stablecoin cross-border remittance proof of concept, illustrating how the same payment corridor problem is being approached from multiple angles simultaneously on Solana.
MoneyGram's Blockchain Strategy: Stellar, Solana, and Beyond
MoneyGram's blockchain strategy has evolved significantly since 2021, when it integrated with Stellar to enable digital asset withdrawals. Earlier in June 2026, the company launched MGUSD, a US dollar stablecoin running natively on Stellar, targeting its existing customer network. The Solana validator step runs in parallel, adding network-level participation on a second major chain rather than replacing one platform with another.
For Solana, the validator addition carries both symbolic and practical weight. Institutional validators bring capital, compliance expertise, and reputational gravity to the validator set. The growing concentration of payments-native companies in both the validator set and the Developer Platform reinforces Solana's positioning as the preferred settlement layer for fintech infrastructure, a case Mastercard's stablecoin settlement integration helped establish when the SDP launched in March 2026.
