Three levels of legal assurance, one platform

Choose the signature level that matches your risk profile. Every level produces a court-ready evidence package with tamper-proof cryptographic sealing.

SES

Simple Electronic Signature

Click-to-sign or draw. Optional SMS OTP verification for stronger identity assurance. Ideal for internal approvals, NDAs, and routine contracts.

  • Draw or type signature
  • Optional SMS OTP verification
  • PAdES-sealed evidence package
  • Legally valid across all EU states
AES

Advanced Electronic Signature

Uniquely linked to the signatory with identity verification. For regulated industries, high-value contracts, and cross-border agreements requiring elevated assurance.

  • Identity verification (IDV)
  • Tamper-detection sealing
  • Qualified timestamping (RFC 3161)
  • Article 26 eIDAS compliant
Highest Legal Weight QES

Qualified Electronic Signature

Equivalent to a handwritten signature under EU law. Uses a qualified certificate from an EU Trust Service Provider. Required for real estate, public procurement, and regulated filings.

  • Qualified certificate (QTSP-issued)
  • Equivalent to handwritten (Art. 25.2)
  • Cross-border EU recognition
  • Long-term validation (PAdES B-LTA)

Built for European regulation, not retrofitted

Every architectural decision — from data residency to key custody — was made with eIDAS, GDPR, and EU court admissibility as first-class requirements.

eIDAS 2.0 Regulation

Full support for SES, AES, and QES as defined by EU Regulation 910/2014 and the revised eIDAS 2.0 framework. Qualified signatures carry the same legal weight as handwritten under Article 25(2) across all 27 member states.

EU-Only Data Residency

All data — documents, signatures, audit logs, PII — stays exclusively in EU data centres (Amsterdam, AMS3). Every sub-processor (infrastructure, email delivery, SMS) operates under EU DPAs with confirmed EU data residency. The application hard-fails on startup if any non-EU region is configured.

GDPR by Design

Documented lawful basis register (Art. 6), full Records of Processing Activities, automated retention enforcement with nightly purge workers, and a deferred-erasure pipeline for Art. 17 right-to-erasure requests — with audit-logged rationale for every decision.

Court-Ready Evidence Packages

Every signed document ships as a complete evidence bundle: PAdES B-LTA sealed PDF, hash-chained audit trail (JSON), certificate chain, and RFC 3161 timestamp receipts. Open it in Adobe Reader — it validates. Present it in a French or Dutch court — it holds.

Tamper-Proof Audit Chain

Append-only hash-chained audit logs with INSERT-only database enforcement. Every event is cryptographically linked to its predecessor. UPDATE and DELETE operations are blocked at the database level — not just the application layer.

Long-Term Validation

PAdES B-LTA signatures remain verifiable for decades — even after the original signing certificate expires. Qualified timestamps from accredited EU TSAs anchor every signature to an irrefutable point in time. Default retention: 10 years, configurable per template.

Everything you need to send, sign, and seal

A complete signing platform with a web interface for humans and a REST API for machines. Built for teams that need both speed and legal weight.

Send in a Few Clicks

Upload a DOCX template, define signing fields, add recipients with ordering — and send. Signers receive a secure link via email, verify via SMS OTP, and sign from any device.

Full REST API

Programmatic envelope creation, status polling, and evidence retrieval. Scoped API keys per admin with rate limiting. Send contracts from your CRM, ERP, or any backend system.

AI Agent & OpenClaw Ready

Agentic API endpoints designed for LLM tool-use. Let your AI agents send contracts, check signing status, and retrieve evidence packages autonomously — with full audit logging.

Multi-Signer Workflows

Define strict signing order per envelope. Recipient 2 cannot sign before Recipient 1 completes. The institutional seal is applied only after all parties have signed and verified.

DOCX Template Engine

Upload Word templates with {{variable}} fields. The platform parses, validates, and renders them into PDF via a sandboxed LibreOffice worker — with no macro execution, no network access.

Enterprise-Grade Security

TLS 1.3 only. Magic-link + TOTP MFA for admins. Hashed API keys. Sandboxed document processing. AES-256 storage encryption. Rate limiting on every endpoint. Zero-trust architecture.

Transparent pricing, no per-signature fees

Every plan includes full EU compliance, evidence packages, and API access. No hidden costs. No surprises on your invoice.
