Shopify and Stripe now accept USDC at checkout, but stablecoin payments expose sensitive data: amounts, wallets, merchant relationships, and repeat purchase patterns. Fairblock addresses this gap by providing a modular encryption SDK that preserves payment privacy without requiring new wallets, bridges, or payment networks.
Stablecoin payments are entering mainstream commerce through Shopify Payments and Stripe, yet lack a critical layer: payment privacy. On public blockchains, amounts, counterparties, timing, merchant relationships, and purchasing patterns become visible, creating risk for both consumers and merchants. Fairblock proposes a unified encryption SDK that integrates into the existing stablecoin payment stack. A single integration brings privacy across multiple chains including Stellar, Solana, Arbitrum, and Base without requiring customers to bridge funds, install new wallets, or accept network lock-in. This becomes especially important as AI agents increasingly execute autonomous payments, where leaked transaction data reveals strategy and vendor relationships.
