About
Holosign is an online electronic signature platform designed to help individuals and businesses send and sign documents quickly and securely. The platform allows users to upload PDF documents and place signature fields, text boxes, dates, and initials using a simple drag-and-drop editor. Recipients can sign documents directly from an email link without needing to create an account or download any software. Holosign supports multi-party signing workflows, allowing users to define the order in which participants sign documents. Each completed document includes a certificate of completion with timestamps, IP addresses, and verification details. The platform also provides a tamper-proof audit trail with SHA-256 document integrity verification. By simplifying digital signing and removing unnecessary complexity, Holosign helps teams finalize agreements faster.

About
Qausal is a web-based electronic-signature platform for preparing and verifying signed PDF documents. Users can upload a PDF, invite one or more signers, assign signing roles and sequence, and track signature progress; invitees can sign without creating an account. Qausal uses ML-DSA-65, the post-quantum digital-signature algorithm standardized as FIPS 204, to create signatures intended to remain verifiable against future quantum-computing risks. Signature data, public keys, and digests are embedded in the signed PDF, and users can download a proof bundle for independent offline verification with open-source tools. Qausal also supports adding a quantum-safe attestation to documents signed through other services without altering the original document. It is intended for organizations that need durable verification of agreements and records, including legal, financial, healthcare, and government-related workflows.
