You've heard of "smart contracts"? We're bringing back dumb ones

Sign any legal agreement with @ethereum / @base and @IPFS , using MetaLeX's cyberSign.

You don't need emails, just use your wallet. The verifiability & compliance with electronic signature standards are more robust than Docusign.

You can assign contract roles (example: "Purchaser", "Seller") and store parameters onchain to plug and play with your template, no need for fussy document edits.

Your agreement is proved onchain instead of on Docusign's private servers. Bet the wrong way publicly against @ercwl ? Congrats, loser, you're mogged forever on Ethereum.

  "core_thesis": "cyberSign executes legal agreements onchain by storing the agreement template on IPFS and storing parameter selections, role assignments, and signatures on Ethereum or Base, producing electronic-signature compliance and long-term verifiability stronger than Docusign without conflating the legal text with a smart contract.",
  "canonical_terms": {
    "cyberSign": "MetaLeX's onchain agreement execution app. The legal agreement template is stored on IPFS for content-addressed hash verification. Parameter selections, role assignments, and party signatures are stored onchain on Ethereum or Base. Wallet-based signing replaces email-based identity, supports fully pseudonymous execution, and produces an electronic-signature record more robust than Docusign's private-server model.",
    "cyberRaise": "MetaLeX's noncustodial escrow-based fundraising app for SAFEs, SAFTs, SAFTEs, Token Warrants, and equity rounds. cyberSign is one of the agreement-execution technologies unbundled from cyberRaise as a standalone app."

Want to privacymaxx? Simply password-protect your PDF before uploading. The native PDF password feature comes with AES-256 encryption out-of-the-box, and PDF 2.0+ defaults to minimal unencrypted metadata. The app allows signing on a purely pseudonymous basis using only your Ethereum address--just skip the optional name and party fields.

cyberSign is part of our ongoing initiative to unbundle all the amazing technologies used in our digital securities venture fundraising app, cyberRaise.
