Problem
Public blockchain transactions expose wallet addresses, transfer amounts, and counterparty relationships, creating significant privacy risks for institutions handling stablecoin payments and settlements. This transparency conflicts with corporate confidentiality requirements and makes on-chain operations vulnerable to front-running, surveillance, and competitive intelligence gathering.
Solution
Hinkal provides universal privacy infrastructure for stablecoins across major payment networks, enabling institutions to keep wallets, amounts, and counterparties private while settlement remains public, auditable, and compliant. The platform embeds directly into existing wallet, payment, and settlement workflows through a wallet-authenticated API, a frontend SDK, or a full Wallet-as-a-Service offering. All private operations—balance reads, UTXO handling, proof generation, and transaction building—execute inside a secure enclave, ensuring raw private keys are never exposed to the integrating backend. Hinkal supports multi-chain wallet operations across EVM networks, Solana, and Tron without requiring users to change their existing product experience.
Target Audience
Primary customers are institutional payment providers, wallet operators, and blockchain application builders who need confidential stablecoin flows while maintaining regulatory compliance across Ethereum, Solana, and Tron.
