Two tools on one plan: quantum-safe e-signatures and NDA-gated data rooms, with a full record of who saw what, every signature and every page-view anchored on-chain.
Nexus puts e-signatures and secure data rooms on one plan. Sign contracts that are legally binding under ESIGN and eIDAS, share documents in NDA-gated view-only rooms with a full audit trail, and prove all of it on the KXCO Armature ledger. Verify seals and Identity credentials are included. It runs on NIST's post-quantum standard, so what you sign today still holds up decades from now.
Anyone can verify a signature or record without a KXCO account. The proof sits on Armature L1.
The firm loads a data room and shares one link.
Each investor accepts the NDA before any document loads, then views the files.
The firm sees who opened what, page by page.
Terms are signed with signatures that stay valid for the life of the deal.
Every step is independently verifiable later, by anyone, with no KXCO account.
Most teams sign in one product and share documents in another. The e-signature vendor holds the signature, a separate data room holds the files, and neither can prove much about the other. When you need to show a contract was signed by the right person and never altered, you are trusting whichever vendor happened to record it, and hoping they are still around when the proof is needed.
The cryptography under all of it is the cryptography quantum computers are expected to break. A signature that is valid today can be forged retroactively once that capability arrives, and adversaries are archiving signed documents now to do exactly that.
Nexus puts signing and data rooms on one trust model. Every signature and every document view is sealed with post-quantum cryptography and anchored on a public ledger, so anyone can check it directly, with no vendor in the middle.
From an institution's root key to every credential, signature and audit entry it produces, verifiable without a network call or vendor dependency.
The same trust model, applied to sharing. Every room is view-only, gated by an NDA, and logged page by page on the ledger.
Two modules on one plan, with proof and identity built in. Use one, or use them together.
Nexus serves anyone who needs signing and document sharing that hold up to scrutiny, today and after the cryptographic deadlines.
Start with a pilot. Open one data room, or run one signing workflow, and see it hold up before rolling it out across the institution.
