Sign contracts.
Legally.
In minutes.
Qualified electronic signatures via Smart-ID and Mobile-ID. Upload a PDF, add signers, get a sealed ASiC-E container — the legal equivalent of a handwritten signature across the EU.

STEP 1 / 4
How it works
Upload the agreement
Drop in a PDF. We compute its SHA-256 hash — what your signers sign is exactly what you sent.
SHA-256 9F2A…C41BAdd signers, set the order
Name, national ID code, country. Signers get an email link — no app to install, no account to create.
Everyone signs with Smart-ID
Each signer confirms a code in their Smart-ID or Mobile-ID app. You receive a sealed .asice container.

The signature, the official time-stamp, and the validity proof are gathered and sealed the instant you confirm on your phone. No queue, no waiting on someone else's servers.
No black box
Most e-signing platforms bolt on decades-old server machinery to do the actual sealing. We wrote our own engine — small enough to run right next to your document, wherever that is.
Opens in official tools
The sealed file is a standard European container, not a proprietary format. It opens and verifies in the same DigiDoc software Baltic governments use.
Checked against the standard
Every version of the engine is tested byte-for-byte against the official validation software, and every sealed file embeds its qualified timestamp and validity proofs — so anyone can re-verify it independently, long after signing.
We built the engine ourselves
When you confirm a signature, a lot happens in one second: your document gets a digital fingerprint, your identity certificate is checked, an official clock stamps the exact time, and everything is sealed into one tamper-proof file. That machinery is ours, built from the ground up — fast, portable, and never a black box.
UNDER THE HOOD: ASiC-E · XAdES-LT · QUALIFIED TIMESTAMPS · OCSP VALIDITY PROOFS · ML-DSA (PQC)Integrate once. When EUDI Wallets arrive across the EU, our signing switchboard offers them automatically and falls back to Smart-ID or Mobile-ID — your flow doesn't change a line. See the roadmap
The EU wants the post-quantum transition underway by end of 2026. Our engine treats signature algorithms as switchable parts, and already signs with the NIST quantum-resistant standard in demo — when qualified post-quantum certificates arrive, your integration doesn't change a line. See the roadmap
Built for regulated business
Qualified Electronic Signatures carry the same legal weight as handwritten ones — across the entire EU.
