MetaLeX Launches cyberSign, DocuSign Alternative on Ethereum

For years, crypto promised that “smart contracts” would replace traditional legal agreements. Code would automate everything. Paperwork would disappear.

Instead of eliminating legal documents, cyberSign keeps agreements in familiar PDF form while moving the proof of signing onto public blockchain infrastructure. cyberSign allows users to sign agreements using Ethereum or Base for proof anchoring and IPFS for storage.

Wallet signatures replace email-based signing flows. MetaLeX argues that this structure can be more durable than traditional e-sign platforms because verification does not rely on a company’s private servers.

What is cyberSign?

cyberSign is a wallet-native agreement signing tool built by MetaLeX. At first glance, it resembles a Web3 version of DocuSign.

But the core idea is different. Traditional e-sign services store documents, logs and audit trails inside proprietary systems. cyberSign instead anchors the signing proof on Ethereum or Base. The document itself can be stored on IPFS, while the blockchain records the cryptographic evidence that the parties signed.

MetaLeX describes its broader mission as building infrastructure where law and blockchain systems work together rather than compete. cyberSign reflects that thinking. It does not try to convert contracts into autonomous code. It focuses on improving how agreements are recorded and verified.

How cyberSign works

A user uploads a PDF agreement. Instead of collecting signatures through email invitations, each party connects their Ethereum wallet and signs directly.

The wallet signature generates cryptographic proof. That proof is anchored onchain. The agreement file can be stored via IPFS.

This structure changes the trust model. Verification does not depend on a single vendor’s internal database. Anyone can independently confirm that a signature occurred at a specific time and corresponds to a specific wallet address.

cyberSign is not trying to enforce the legal terms automatically. Courts and legal systems still handle enforcement. The blockchain functions as an evidence layer.

Why onchain proof matters

Many legal disputes are not about what was written. They are about what was signed, when it was signed, and whether the record can be trusted. Traditional e-signature providers maintain audit logs on private infrastructure. That works, but it creates long-term dependency on the platform.

If a company changes providers, loses account access, or needs independent verification years later, it must rely on that vendor’s systems. Onchain proof introduces durability.

The signature evidence remains publicly verifiable regardless of platform changes. Even if MetaLeX ceased operating, the blockchain record would still exist.

cyberSign also attempts to reduce friction in repetitive legal workflows. Most agreements are built from templates. The same structure is reused with different names, dates or values.

Manual editing introduces errors and version confusion. cyberSign allows users to assign defined roles such as Purchaser or Seller. It also supports structured parameters that can plug into templates without rewriting entire documents.

Instead of editing PDFs repeatedly, users can reuse agreement frameworks with updated variables. Over time, this can simplify operations for startups, DAOs, venture deals and recurring commercial arrangements.

Users can password-protect their PDFs before upload. Standard PDF encryption can provide strong document-level security. The file stored on IPFS remains encrypted unless the password is shared.

cyberSign also allows signing based solely on Ethereum addresses. Optional name fields can be skipped, enabling pseudonymous participation when appropriate.

cyberSign within the cyberRaise stack

cyberSign is part of MetaLeX’s effort to modularize tools originally developed for cyberRaise, its digital securities fundraising platform. cyberRaise aims to streamline venture fundraising by integrating legal agreements, structured deal terms and blockchain-based settlement logic.

By releasing cyberSign separately, MetaLeX is making one piece of that infrastructure accessible to a broader audience. This reflects a wider trend in Web3. Tools initially built for tokenized finance are being repurposed as general digital infrastructure.

cyberSign suggests that public blockchain infrastructure can serve as a durable, neutral proof system for agreements. It does not promise automatic enforcement or radical transformation. Instead, it improves a specific layer of the process.
