SignHive gives your team a modern signing workflow on top of a tamper-evident evidence kernel — so every signed document holds up when it matters. Upload a PDF, place signature fields, and send for legally binding e-signature in minutes.
Every signature is written into a hash-linked audit chain, the final PDF is assembled and sealed server-side, and documents are anchored to the Bitcoin blockchain via OpenTimestamps for independent verification. ESIGN, UETA, eIDAS, GDPR and CCPA compliant, with a HIPAA BAA available on Enterprise.
Self-sign unlimited documents free with no account. Free plans include 3 signature sends per month; paid plans from $12/month add unlimited sends, templates, bulk sending, team seats, API access, and white-label branding.
