Rain Disrupts Payments Game: Solana, Tron, and Stellar Join Stablecoin Card Network

Another day, another crypto payment play—but this one might actually stick. Rain just plugged Solana, Tron, and Stellar into its global stablecoin card system, letting users spend digital dollars without begging banks for permission.

Speed demons unite: Solana’s 2,000 TPS meets Visa rails

Tron’s USDT dominance gets a real-world checkout lane, while Stellar’s cross-border chops could finally shine. Because nothing says ’financial revolution’ like buying coffee with blockchain—unless you count the 3% card fees as tribute to the old system.

Traditional finance won’t notice... until they’re onboarding clients via a Lightning node.

TLDR

• Rain Adds Solana, Tron & Stellar to Power Global Stablecoin Cards.
• Stablecoin Spending Goes Global as Rain Expands Multi-Chain Access.
• Rain Boosts Real-World Payments with Solana, Tron, Stellar Support.
• Neobanks and Wallets Can Now Issue Visa Cards on 6 Blockchains via Rain.
• Rain’s Card Network Now Covers Remittances, Microtransactions & Emerging Markets.

Rain has expanded its stablecoin card network by adding support for Solana, Tron, and stellar blockchains. This strategic move enhances Rain’s multi-chain capabilities and accelerates global access to stablecoin-linked card programs. The integration comes amid increasing demand for real-world stablecoin utility through card-based payments.

Solana Integration Enhances Speed and Programmable Payments

Rain has enabled solana integration to support developers building fast and scalable payment solutions. Solana’s high-throughput performance allows Rain’s partners to issue branded Visa cards directly connected to users’ wallets. Consequently, transactions on Solana remain quick and low-cost, suitable for daily purchases and microtransactions.

Rain now supports @Solana, @TronDAO, and @StellarOrg — enabling partners to launch stablecoin-powered card programs across multiple chains. @kastcard (Solana) and @OfframpXYZ (Tron) are already live.

Neobank KAST is launching stablecoin-powered cards using Rain’s API and Solana’s infrastructure. The cards allow real-time spending of stablecoins while maintaining direct wallet control. This supports seamless consumer and B2B payments across multiple regions.

Rain’s Solana support aligns with growing demand for blockchain-powered financial services that combine speed, transparency, and low fees. It simplifies how fintechs and developers deploy programmable card payments using stablecoins. The integration helps address challenges in traditional payment systems by offering near-instant transactions and lower costs.

Tron Integration Targets Stablecoin Spending in Emerging Markets

Rain has also integrated TRON to enable card programs in stablecoin-dominant markets such as Latin America. Tron processes large volumes of stablecoins daily, making it suitable for on-chain to off-chain payment conversions. With Rain’s support, Tron-based projects can now issue Visa cards that operate across global payment networks.

Fintech firm Offramp is using Tron integration to deliver card solutions to underserved regions. Offramp’s users can spend USDT and other stablecoins at over 150 million Visa-accepting merchants. This allows for improved access to stable assets and reduces dependency on volatile local currencies.

Rain’s tron support further strengthens its offering in markets that rely heavily on digital dollar use. It also reinforces its role in expanding financial inclusion through blockchain-powered services. Developers can tap Rain’s infrastructure to quickly roll out compliant, dollar-based payment tools with a global reach.

Stellar Integration Supports Remittance and Cross-Border Payments

Stellar integration positions Rain to capture new demand in the global remittance and cross-border payment sectors. Stellar’s low-cost and remittance-focused design makes it ideal for sending and receiving funds across borders. Rain enables platforms to issue branded cards backed by Stellar wallets and stablecoin reserves.

This integration helps extend stablecoin usability into sectors where traditional cross-border transfers are slow and expensive. Users can now access funds directly via card without needing bank accounts or intermediaries. It improves speed and efficiency while reducing friction in international money movement.

Rain unlocks another blockchain with strong real-world utility for everyday financial needs. It allows wallet providers to support users in regions where remittances drive local economies. Developers can rely on Rain’s API to bridge Stellar payments with mainstream merchant access.

Rain Expands Multi-Chain Card Infrastructure After Series A Round

Rain supports Arbitrum, Optimism, Polygon, Solana, Tron, and Stellar, enabling card issuance across six major blockchain ecosystems. In March, the company raised $24.5 million in a Series A round to fuel expansion. These funds support global scaling, partner onboarding, and infrastructure development.

Rain remains the only Visa Principal Member offering direct multi-chain card issuance with support for custodial and non-custodial wallets. It continues to attract partners building neobanks, fintechs, and digital wallets needing compliant global payment solutions. Rain’s infrastructure simplifies how developers bring stablecoin payments to the real world.
