SELLO — electronic signature & digital trust

Sign, seal, and verify documents with legal force — built for Moroccan law and the YORYX ecosystem.

SELLO turns any document into a legally binding, tamper-evident record. Signatures, timestamps, and organizational seals are verifiable by anyone, anywhere — with a complete audit trail behind every signature.

What SELLO gives you

Legally binding e-signatures

Electronic signatures aligned with Moroccan Law 53-05 on electronic signature and trust services, with what-you-see-is-what-you-sign integrity.

Instant verification

Anyone can verify a signed document's authenticity and integrity in seconds — no account required, no tampering possible.

Qualified timestamps

Every signature is anchored to a trusted, qualified timestamp that proves exactly when a document was signed.

Organizational seals

Seal invoices, contracts, and certificates in your organization's name, not just an individual's — ideal for companies and administrations.

Tamper-evident audit trail

Every action — open, sign, seal, verify — is recorded in an immutable trail that stands up as legal evidence.

Built into YORYX

Sign documents straight from SALDO, ORDO, and the rest of the YORYX platform through shared contracts — no copy-paste, no extra tools.

Sign with confidence

Give every contract, invoice, and certificate the legal weight it deserves.
