Use Cases

nChain Sign allows you to sign and manage documents digitally, improving the efficiency of your processes. The platform enhances security, transparency and allows independent verification of signatures by recording document trails on chain.

These benefits can be leveraged in multiple contexts with traditional document signatures but also validation gates, proof of reviews and versioning.

When high security is needed for signatures (large transactions, confidential information, etc.), nChain patented technology allowed us to develop a unique solution where users can choose to keep custody of their signing keys on separate hardware devices.

Use Case
