E-signature software features The signing workflow,
with proof built in
Upload, place fields, collect signatures, track every step. Then LedgerSign anchors the finished document on the Hedera public blockchain, so you can still prove what was signed years from now.
Blockchain Verification
Every signed document is hashed with SHA-256 and anchored on Hedera, a public blockchain. The result is permanent, immutable proof of exactly what was agreed.
- SHA-256 fingerprint of the final signed document
- Timestamped record on the Hedera Consensus Service
- Instant, independent verification for third parties
- Certificate of Completion bundled with every document

Tamper-Proof Documents
Change a single byte after signing and the fingerprints no longer match. Nobody has to hunt for alterations; they announce themselves.
- Hash-based integrity checks
- Any modification is instantly evident
- Original fingerprint preserved on-chain forever
- Court-ready evidence of integrity
