# Sigillum - **Website:** - **Primary alias:** `sigillums.com` ## Description Sigillum is a proof and record-integrity platform operated by Hygenox Markets Limited. It helps organisations establish what a record was, when it was sealed, and who sealed it, creating a tamper-evident, append-only chain anchored to three independent public rails. Documents remain in the customer’s systems: Sigillum records a one-way fingerprint rather than the file itself, and users can verify proofs independently. Each seal includes the claimed event time and an independently verifiable recording time; optional eIDAS-qualified timestamps are available. The platform serves legal, insurance, audit, energy, enterprise and financial-services, and AI-accountability use cases. Organisations can attest contracts, claims, audit evidence, sustainability records, decisions, model events, and regulatory submissions. Sigillum also provides tools to verify proofs, a browser-based file fingerprinting experience, an API for integrating event seals, and consultations and evidence walkthroughs. Its aim is to give parties a shared, verifiable record for disputes and regulatory scrutiny, while making clear that a seal proves a record’s integrity and timing—not the truth of its contents or any legal outcome. ## Industries - 🖥 Computers Electronics and Technology - 🖥 Blockchain and Cryptocurrency _(under Computers Electronics and Technology)_ - 🖥 Computer Security _(under Computers Electronics and Technology)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/id2bwDZONU/w/512/h/512/theme/light/logo.png?c=1bxid64Mup7aczewSAYMX&t=1792038986465) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Amazon | #2e6b4f | accent | | Nile Blue | #1a2f4f | dark | | Merino | #f8f4ed | light | ## Fonts - Bookman Old Style — asset _(custom)_ - Geist Variable — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
