Human-Centric Cryptocurrency Inheritance
GRIFORTIS provides cryptographically sound solutions for securing your digital legacy, combining academic rigor with practical tools that anyone can use—even with just pencil and paper.
Introducing Schiavinato Sharing
A novel secret sharing scheme designed for human execution and verification. Unlike traditional schemes, Schiavinato Sharing allows heirs to recover secrets manually without specialized software—ensuring your legacy survives technological changes.
Our Philosophy
Security Above All
Cryptographic soundness is non-negotiable. Every design decision prioritizes asset protection over convenience.
Human-First Approach
Tools must be usable by non-technical heirs. We design for manual recovery paths for true disaster resilience.
Open Source Foundation
Radical transparency. Core libraries are MIT Licensed and the Whitepaper is CC BY 4.0. Trust requires auditability.
Human Executable
Recovery is possible with pencil, paper, and arithmetic in a finite field GF(2053). No black-box software dependencies.
Open Source Resources
JavaScript / TypeScript
Production-ready NPM package for Node.js and browser environments.

Renato Schiavinato Lopez
The Architect
Renato is the creator of the Schiavinato Sharing cryptographic scheme and the founder of GRIFORTIS. With a deep focus on the intersection of cryptography and human usability, he developed this system to solve the critical "last mile" problem of cryptocurrency inheritance: ensuring access without reliance on third-party custodians or ephemeral technology.
GRIFORTIS was founded to provide a trusted, authoritative source for inheritance planning that respects the sovereignty of digital assets.
