Decentralized Identity Infrastructure for Flow

Open source decentralized identity, NFT and wallet solutions for developers and businesses.

About Flow

Flow is a fast, decentralized, and developer-friendly blockchain, designed as the foundation for a new generation of games, apps, and the digital assets that power them. It is based on a unique, multi-role architecture, and designed to scale without sharding.

Holistic Open Source Tools

Flow and walt.id collaborated on building an open source NFT infrastructure layer for the Flow ecosystem. As a result, developers now have “on-chain identity” tools that enable various capabilities for Non-Fungible Tokens (NFTs) and Soulbound Tokens (SBTs) which makes the NFT ecosystem on Flow more accessible to build advanced use cases. At their core, these open source tools enable four capabilities:

  • Manage NFTs (in an app/wallet)

  • Verify NFTs (ownership, metadata)

  • Unlock NFTs for web2 apps


These capabilities can be used to build a great variety of use cases ranging from collectibles, memberships or public profiles to utility, access management and beyond.
