Sign Documents

The Sign Documents plugin lets you sign important company documents in a way that is cryptographically verifiable on-chain. The signature is anchored to your entity's wallet, so anyone can prove that the document was signed by an authorised signer of your company — without trusting any centralised service.

Use it to sign:

• Operating agreements and amendments
• Member-consent resolutions and votes
• Contracts and NDAs that need a tamper-proof signature trail
• Internal sign-offs that should be auditable later

Steps

1. Open the plugin. From the DashPanel, select your entity, click Plugins in the left menu, then Add to open the Sign Documents plugin.
2. Upload the document. Drag in the file (PDF, DOCX, MD) or paste a link to a document stored on your favourite document host.
3. Review the hash. OtoCo computes a cryptographic hash of the document and shows it on screen. The hash uniquely identifies the file — any change to the content produces a different hash.
4. Sign. Click Sign, then approve the signing transaction in your connected wallet. OtoCo records the hash, your address, and the timestamp on-chain.
5. Share the proof. Send the document together with the OtoCo signing receipt to your counterparty. Anyone can re-hash the file and check the on-chain record to verify the signature.

Cost

The Sign Documents plugin is free to install. You only pay gas for the on-chain signature transaction.

Where signatures live

All signatures created with this plugin are listed on your entity's Files & Templates tab so you can revisit them later. They are also visible to Genco, the OtoCo AI assistant, which can answer questions like "what did I sign last month?".
