Information only — no U.S. participation today. Register a non-binding indication for the pipeline (for non-U.S. capital or a post-sanctions world).

Not legal, tax, or investment advice — and not authorization for any transaction. U.S. sanctions (the Cuban Assets Control Regulations, 31 CFR Part 515) heavily restrict — and in most cases prohibit — dealings between U.S. persons and Cuba, including any form of investment or equity in a Cuban business. The rules are complex, fact-specific, and change; nothing on this site is a determination that any transaction is lawful. Structure anything Cuba-facing only with qualified OFAC sanctions counsel, and screen every party (names, entities, wallets) with QvaPay Sentinel.
