Lexato turns digital content — web pages, chats, posts, emails — into evidence with legal validity recognized by Brazilian courts.
Digital content can be altered or erased in seconds. Lexato exists so that doesn't destroy the truth: every capture is certified, recorded on a blockchain, and timestamped with an official date — creating a record courts accept as evidence.
The platform was born from the real need of lawyers, businesses, and citizens who had no fast, affordable, and legally valid way to preserve digital evidence — without relying on a notary.
Blockchains
Encryption
Minimum retention
Verifiable
Born from an observation: digital evidence had no way to survive a legal challenge. Research began in blockchain, cryptography, and Brazilian legislation.
Three blockchains, AES-256 encryption, and ISO 27037 compliance form the technical foundation. The goal: evidence that withstands any forensic examination.
The platform goes live with a desktop application, ICP-Brasil timestamp, and a self-contained PDF/A-3 forensic report — ready to file in court.
The platform becomes available to everyone. The desktop app is simple and lets anyone preserve digital evidence.
Every record is immutable and verifiable by anyone.
Open source, auditable process, traceable outcome.
Real protection: from capture to storage, no shortcuts.
Post-quantum cryptography today — preparation ahead of the threat.
Clear, straightforward interface designed for anyone to use.
No notary needed — anyone can certify from home.
Digital truth is fragile — it can be edited, erased, challenged. Lexato exists to make facts permanent.
