Assina Stack provides an electronic signature platform focused on signing and collecting signatures through WhatsApp. The service allows users to upload PDFs and send signing links to recipients, who confirm their identity and sign without leaving the page. Each signature includes an audit trail, cryptographic seal, and independent third-party timestamps aligned with Brazilian regulations such as Lei 14.063/2020 and MP 2.200-2/2001. Additional features include identity verification with one-time codes and selfie proof of life, an automatic client registry, and a dashboard for tracking document status. The platform also delivers sealed copies of completed documents back to the sender via WhatsApp.
