What are Stamps?

Passport Stamps is an aggregate, real-time verification tool that can enable users to prove their unique humanity using a variety of different verification methods, and for developers to access these humanity proofs via the Stamps API or smart contracts.

Verified Credentials do not contain any personal identifying information! They simply demonstrate, using a cryptographic signature, that the user gave access to a specific app and that some criteria were met. Learn more about how Human Passport is privacy preserving (opens in a new tab).

Use cases

Developers can integrate Passport in a variety of different programs and apps in the web3 ecosystem, as demonstrated by the following use case examples:

• Sybil resistance for faucets, bundlers and airdrops
• Gating access to content, events, polls, or communities
• Priority weighting votes
• Proving trustworthiness

Passport Stamps is a versatile and valuable tool for managing access, promoting transparency, and establishing trust within different web3 environments.

Available developer tools

Passport score and Stamp data can be retrieved in two ways:

• Stamps API v2: Retrieves the Stamp-based Unique Humanity Score and associated metadata for a specified address.
• Passport Smart Contracts: Interacts with a blockchain to retrieve Stamp-based Unique Humanity Scores associated with a specific address.

Passport's Stamps-based product can also be delivered to users in a few different ways:

• Passport App (opens in a new tab): The standard Passport app that allows users to manage their Stamps and view their Passport score.
• Passport Embed: A widget that can be embedded on a website or app to allow users to verify their identity.
• Custom Passport: A dashboard that can be customized to the unique needs of your ecosystem.

Stamps API v2

The Stamps API v2 serves as a powerful tool for developers, offering access to Passport scores and Stamps via several REST endpoints.

Passport Embed

Passport Embeds is a premium offering that lets websites integrate Human Passport's Stamps-based verification directly on their website or app, eliminating the need for users to be redirected elsewhere.

Custom Passport

Custom Passport is a premium offering that enables partners to develop a Human Passport dashboard that is customized to the unique needs of their ecosystem. This offering enables several additional features above and beyond what is offered on the standard Passport app, which can enable tailored proof of humanity solutions.

Onchain Passport

Passport's smart contracts enable you to pull score and Stamp data directly from the blockchain to enable a truly decentralized integration.
