Accelerate enterprise document workflows with legally binding signatures, drag-and-drop placement, API-driven automation, and immutable blockchain audit logs.
From simple electronic signatures to PKI-based digital signing — with blockchain-anchored audit trails for tamper-proof integrity verification.
Organizations still rely on manual, fragmented signing processes — creating delays, disputes, and compliance risks.
Paper-based and email-based signing creates bottlenecks that slow down critical business processes by days or weeks. Print, sign, scan, email — a cycle repeated thousands of times across the enterprise.
Without cryptographic verification, signature authenticity can be challenged in court. Wet signatures provide no proof of intent, identity, or timestamp — creating legal exposure.
Traditional signing processes leave fragmented, easily manipulated audit logs. When regulators ask for proof, organizations scramble to reconstruct timelines from emails and filing cabinets.
Connecting signing workflows to existing ERP, HR, CRM, and government systems requires months of custom development — and constant maintenance as APIs change.
Without blockchain anchoring, signed documents can be silently modified after signing with no cryptographic proof of integrity.
Regulatory frameworks demand verifiable signing processes. Without proper identity verification and timestamping, signed documents may not hold up in court.
A complete digital signature infrastructure — from simple click-to-sign to PKI-based cryptographic signing with blockchain integrity.
Support Simple Electronic (SES), Advanced Electronic (AES), and PKI-based Digital Signatures with certificate validation and HSM integration.
Visual document preview with drag-and-drop fields — signatures, text, dates, checkboxes, and stamps — with template saving.
Programmatic signing with REST APIs — coordinate-based placement, anchor-text detection, bulk signing, and embedded links.
Sequential, parallel, and conditional approval routing with automated reminders, expiration, and real-time status tracking.
Every signing event is hashed and anchored to blockchain — creating immutable, independently verifiable audit trails.
AES-256 encryption, TLS 1.3, HSM support, RBAC, MFA, and compliance-ready architecture for regulated industries.
NEDO Sign connects to any application — receive documents via API from upstream systems, apply digital signatures, and distribute signed documents to downstream platforms.
Not just another e-signature tool — a complete enterprise signing infrastructure with blockchain integrity.
Every signing event is cryptographically hashed and anchored to blockchain — creating tamper-proof, independently verifiable audit logs.
Complete REST API coverage for every operation — document creation, signer management, field placement, signing, verification, and blockchain proof.
Visual document preview with intuitive drag-and-drop placement of signature fields, text, dates, checkboxes, and stamps.
Deploy to your own infrastructure for maximum control, use our cloud for convenience, or run hybrid — your choice.
Pre-built integrations for ERP, HR, CRM, government platforms, and banking systems — with webhook support for real-time events.
NEDO Sign is built on a modular, layered architecture designed for security, scalability, and seamless integration.
