Payment Rails for Web3 Super Apps on Solana

Managed backend infrastructure for Web3 applications to integrate self-custody wallets, payment cards, and fiat on/off-ramps without rebuilding compliance and settlement logic.

The problem

Web3 super-app builders must integrate Solana USDC wallets, payment cards, fiat channels, and KYC/AML compliance from scratch. Each founder rebuilds the same payment rails, settlement logic, and regulatory plumbing; most launch unprepared and miss critical compliance or card-network integrations.

Who has it: Seed-to-Series-A Web3 founders building consumer super apps or wallets on Solana, targeting Asia-Pacific or European launch markets, with $500k–$2M runway.

Why now: Solana ecosystem growth, USDC adoption, and impending US payments regulation create urgency for Web3 builders to ship credible payment infrastructure fast. Card networks now actively support stablecoin integrations.
