VAULT3

Secure file sharing DApp that leverages Cardano wallets and tokens for content access control, serving creators and projects with encryption.

Overview

VAULT3 is a service on Cardano that lets creators and projects restrict access to files, forms, and online experiences based on what a visitor holds in their Cardano wallet1. A creator uploads content, sets the conditions for who can see it (specific tokens, NFTs, stake pool delegation, or a list of approved wallets), and shares a single link. Anyone who clicks the link connects a wallet, the wallet is checked against the rules, and the content opens for visitors who qualify.

VAULT3 is aimed at creators, NFT projects, DApp teams (apps that run on a blockchain), and communities that want to reward token holders without building their own access infrastructure. The platform ships as a hosted web app, a public data interface for other tools, and an open-source JavaScript code library so that projects can embed VAULT3 gates directly inside their own websites.

Key Features

  • Wallet-based access conditions. Gates can require specific tokens, NFT collections, stake pool delegation (showing support for a particular Cardano validator), or membership in an approved wallet list, combined through the web app's condition builder1.
  • Open-source JavaScript library. The library was produced under Cardano Catalyst Fund 11 and released under the Apache License, covering wallet connection, content unlock, and customisable visual components developers can brand for their own site2.
  • No-code token-gated forms. A forms builder collects data from token holders and stake delegators, including shipping addresses for physical product fulfilment, without writing any code1.
  • Hosted dashboard and data interface. A creator dashboard at app.vault3.io handles day-to-day management of gates, while a public data interface at api.vault3.io lets external tools query and read gate information.
  • Partner integrations across Cardano tooling. The landing page lists NMKR, Maestro, and Entropi Labs as ecosystem partners, placing VAULT3 alongside tools used by NFT marketplaces and minting platforms1.

What to Expect

Using VAULT3 follows a three-step flow: create, share, access. Creators upload content or build a form through the hosted dashboard, set access conditions and branding, then connect a wallet to publish the gate1. The resulting link can be posted on social media, embedded in a website, or attached to an NFT so that the asset itself becomes the key. Visitors who click the link connect a Cardano wallet and sign a read-only proof of what they hold, so the connection cannot move any of their assets. When a wallet does not qualify, the page shows the exact access requirements rather than a generic error, helping visitors understand which token or stake delegation would let them in.

VAULT3 is operated by parent entity GranADA Pool, a Cardano stake pool operator that lists VAULT3 among its product portfolio with a live status3. The team funded multiple deliverables through Project Catalyst, including the foundational data-gating service under Fund 104 and the open-source JavaScript library under Fund 11, completed in December 20242. Builders evaluating VAULT3 should note the trade-offs. The hosted surface reduces integration effort, while the library path preserves brand control at the cost of implementation work. A public GitHub repository for the library is not linked from vault3.io, so technical adopters should contact the team through Discord or Telegram to request repository access. No project-issued token is in circulation.
