Chaindoc is a Latvia-based agreement management platform that combines electronic signatures, identity verification (KYC), and contract payments in a single workflow. Signed documents receive a SHA-256 hash recorded on a blockchain to create a tamper-evident audit trail, and signatures are designed to be eIDAS- and ESIGN-compliant. The service holds ISO 27001 and CSA STAR certifications and targets businesses and freelancers in regulated sectors such as real estate, healthcare, insurance, and IT services.
