Introduction

Overview

VAULT3 is a token-gating service on Cardano that lets creators and projects restrict access to files, forms, and experiences based on what a visitor holds in their wallet1. A creator uploads content, defines access conditions against native tokens, NFTs, stake delegation, or whitelists, and shares a single link. The service targets creators, NFT projects, DApp teams, and communities that want to reward token holders without building gating infrastructure from scratch. The platform ships as a hosted web app, a public GraphQL API, and an open-source JavaScript SDK for embedding gates directly inside third-party sites.

Key Features
  • Wallet-based access conditions. Gates can require specific fungible tokens, NFT policy IDs, stake pool delegation, or membership in a whitelist, combined through the web app's condition builder1.
  • Open-source JavaScript SDK. The SDK was produced under Catalyst Fund 11 and released under Apache License, covering wallet connection, content unlock, and brandable UI components2.
  • No-code token-gated forms. A forms builder collects data from token holders and delegators, including shipping addresses for physical product fulfillment, without writing code1.
  • GraphQL API and managed app. A GraphQL endpoint at api.vault3.io lets external tools query gates programmatically, while app.vault3.io provides the hosted creator dashboard for managing spaces.
  • Partner integrations. The landing page lists NMKR, JPG Store, Maestro, and Entropi Labs as ecosystem partners, positioning VAULT3 alongside tooling 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 at app.vault3.io, customize 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 token metadata so that the asset itself becomes the key. Visitors who click the link connect a Cardano wallet, sign a read-only ownership proof, and see content unlock when conditions are met. When a wallet does not qualify, the page shows the specific access requirements rather than a generic error, helping visitors understand which token or stake delegation would grant them access.

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