W3i Software is a West Lafayette, Indiana blockchain infrastructure company that builds and operates compliance-grade infrastructure for regulated stablecoin issuance. It describes itself as the infrastructure layer for global stablecoin issuance, providing a full-stack system covering minting, reserve management, banking integrations, and regulatory compliance that licensed issuers run rather than build themselves. Its infrastructure powers USDM, Cardano's first fiat-backed stablecoin, issued by licensed partner Moneta Digital with daily on-chain reserve attestations and alignment to the EU's MiCA framework. In January 2026 the company announced shieldUSD, a privacy-preserving USD stablecoin for the Midnight Network, and in March 2025 Hoskinson Family Office invested $1.5 million in the company.
