Invoance provides technical verification and proof infrastructure for digital records. Invoance does not issue legal, financial, or regulatory advice.

Records anchored through Invoance are cryptographically signed and tamper-evident by design. Invoance does not verify the accuracy, legality, or authenticity of document contents, only that a record existed in a specific form at a specific time. Verification links are publicly resolvable and do not require authentication. Invoance does not act as a custodian of funds, a legal authority, or a regulated financial entity. Use of Invoance does not constitute legal compliance. Consult qualified counsel for your specific obligations.
