What new developer‑facing capabilities has Pi Network added?

Pi Network now offers (1) local device‑side storage for whitelisted apps, (2) a Staking Data API that provides app‑specific staking information, and (3) native file/video sharing via `Pi.shareFile`. A consolidated developer documentation site also bundles registration, SDK, payments, sandbox, and launch guides in one place (Pi Network, 2026).

How does the Local Storage capability help Pi app developers?

The Local Storage feature lets apps store preferences, session state, and lightweight data directly on the user’s device, reducing reliance on external databases and speeding up app performance (Pi Network, 2026).

What can developers do with the Staking Data API?

The Staking Data API exposes app‑specific effective staking metrics, enabling developers to build loyalty programs, enforce access rules, and create engagement logic based on a user’s staking level (Pi Network, 2026).

How does `Pi.shareFile` improve user experience in Pi apps?

`Pi.shareFile` allows native sharing of files and videos—including receipts, media, and dispute evidence—directly from the app to other users or external platforms, simplifying content exchange (Pi Network, 2026).

Pi Network’s New Developer Capabilities: What Developers Can Actually Build With Them

Three new capabilities that matter to developers

Pi Network has added three developer-facing capabilities to its platform: local storage for an initial set of whitelisted apps, an API for accessing app-specific staking data, and native file and video sharing through Pi.shareFile. At the same time, Pi has released a consolidated developer documentation site intended to bring registration, SDK references, authentication, payments, sandbox development, and launch guidance into one place. (Pi Network)

These changes are more useful when looked at from an application architecture perspective rather than simply as a list of new features.

A developer building a Pi App now has more options for deciding where application state lives, how an app can use ecosystem-level signals, and how users can move content out of the app. The documentation changes are equally important because they affect how quickly a developer can go from an idea to a working integration.

Capability	What it provides	Where it can help
Local storage	Device-side storage for supported apps	Preferences, session state, lightweight local data
Staking Data API	App-specific effective staking information	Loyalty, access rules, app-specific engagement logic
`Pi.shareFile`	Native file and video sharing	Receipts, media, marketplace disputes, content sharing
New developer docs	Centralized technical documentation	Registration, SDK integration, sandbox, payments, launch

The important detail is that these capabilities are not all-purpose replacements for a backend. Each one solves a specific part of the application experience.

Local storage: useful for state that does not belong on your server

One of the most practical additions is local storage support inside Pi Browser.

The basic idea is simple: an eligible Pi App can keep certain information directly on the Pioneer’s device instead of sending that information to its own backend.

That makes sense for data such as:

UI preferences
temporary session state
locally relevant settings
lightweight app state
information that does not need server-side persistence

For developers, the appeal is not only performance. It can also reduce the amount of infrastructure needed for information that does not need to leave the device.

Pi says the data is managed by Pi Browser and remains on the Pioneer’s device rather than being uploaded to Pi servers. The capability is also intended to provide a more consistent storage experience across iOS and Android. (Pi Network)

That changes the architecture of a small app in an interesting way.

Instead of treating every piece of state like this:

User
  |
  v
Pi App
  |
  v
Backend
  |
  v
Database

some application state can now remain closer to the user:

User
  |
  v
Pi App
  |
  +----> Local device storage
  |
  +----> Backend
           |
           v
        Database

The distinction is important.

Local storage is not a replacement for your database

A developer should not move important business data into local storage simply because it is now available.

If the application needs information to:

survive device changes
synchronize across multiple devices
support multiple users
be processed by a backend
remain available after local data is cleared
participate in server-side business logic

then that information still belongs in an appropriate backend system.

Pi explicitly notes that the current local storage implementation uses a limited shared pool for whitelisted apps and that stale data may be removed when storage becomes full. It is therefore not intended to be guaranteed permanent storage. (Pi Network)

This is probably the most important limitation developers should understand before using it.

Device-bound state changes how developers should think about user data

The new model also introduces a distinction between account identity and device-local state.

Pi notes that locally stored information is associated with a particular account and device and does not automatically follow the user when they move to another device. (Pi Network)

That means a developer should ask a very practical question for every piece of data:

Does this information belong to the user, or does it belong to this particular device?

A theme preference may belong to the device.

An order history does not.

A temporary onboarding state might belong locally.

A purchased item should almost certainly be represented in server-side application data.

That distinction can prevent a surprisingly large number of synchronization problems later.

A better use case: reducing unnecessary backend work

Consider a marketplace application.

There may be hundreds of small pieces of state that do not need to be stored permanently:

whether the user has dismissed a banner
the last selected category
preferred layout
temporary filter settings
an incomplete local form
UI preferences

Sending every one of these values to a backend creates unnecessary requests and database writes.

Local storage gives developers another option.

The backend can focus on things that actually matter to the application:

Backend
- accounts
- orders
- listings
- payments
- permissions
- messages
- transactions

Local device
- preferences
- temporary state
- UI configuration
- lightweight session information

That separation can make an application simpler and cheaper to operate.

The important part is resisting the temptation to treat local storage as a general-purpose database.

Why Pi is starting with whitelisted apps

The local storage capability is currently limited to an initial set of whitelisted apps.

That may feel restrictive to developers who want immediate access, but it also makes sense for a capability that deals directly with device storage and application state.

Pi says the app-by-app rollout allows it to evaluate performance and storage behavior across different devices, storage conditions, and real usage patterns. (Pi Network)

For developers, the practical takeaway is straightforward:

Design around the capability, but do not make your entire application dependent on it unless your app has access and the behavior is appropriate for your use case.

App-specific staking data: turning ecosystem staking into application logic

The second major addition is the Staking Data API.

This is more interesting from a product design perspective than it may initially appear.

Pi's Ecosystem Directory Staking feature allows Pioneers to stake Pi toward applications. The new API allows a developer to retrieve the effective amount staked for its own app.

The effective stake is not simply the raw amount of Pi.

Pi explains that it takes into account both the amount staked and a boost associated with the duration of the stake. (Pi Network)

That gives an application an ecosystem-level signal it can potentially use in its own logic.

What "app-specific" means

The API is designed around the requesting application.

That matters because a developer should not think of this as a general endpoint for inspecting everyone's staking activity across the ecosystem.

Instead, an application can obtain the effective staking information associated with that application.

For example:

Pioneer
   |
   v
Pi App
   |
   v
Staking Data API
   |
   v
Effective stake for this app

The application can then decide how, if at all, that information should influence its product experience.

Pi currently requires apps requesting access to this API to be whitelisted. (Pi Network)

What could developers do with staking data?

The API does not automatically create a product feature.

The interesting part is what developers build around the signal.

Potential applications could include:

Community prioritization

An app could use staking participation as one input into a community-oriented experience.

Support or engagement tiers

A developer could potentially design different application experiences around levels of participation, provided the resulting rules are transparent and consistent with the platform's terms.

Loyalty mechanics

An app could use staking-related participation as one component of a broader loyalty system.

Ecosystem discovery

An application could incorporate staking information into experiences where community support is already relevant.

Reputation-style signals

Developers could explore whether staking participation is useful as one signal among several for certain application features.

The important phrase here is one signal among several.

Staking data should not automatically be treated as a universal measure of reputation, trustworthiness, quality, or user value.

A large stake does not tell a developer everything about a person.

Effective stake is more useful than a simple balance

The distinction between raw stake and effective stake is worth paying attention to.

Suppose two users stake the same amount of Pi.

Their effective stake may differ if the duration component produces different boosts.

That means an application receiving effective stake is not simply asking:

"How much Pi did this user put into the app?"

It is working with a value that incorporates both amount and staking duration.

That makes the signal more suitable for applications that care about sustained participation rather than only a one-time action.

Developers should still document exactly how they use this value.

If an application grants access, benefits, or privileges based on staking, users should be able to understand the relationship between their staking activity and the resulting application behavior.

File and video sharing: a small API with a surprisingly broad impact

The third capability is much easier to understand.

Developers can use Pi.shareFile to allow users to share files, including video, through the phone's native sharing functionality. (Pi Network)

This sounds like a relatively small SDK addition, but native sharing solves a common problem in mobile web applications.

Without a native share capability, a developer may have to build a custom workflow around:

file generation
downloads
device storage
sharing instructions
separate integrations
platform-specific behavior

A native share flow removes much of that friction.

Pi gives examples such as a marketplace where a user needs to share a receipt or images related to a disputed item. It can also be used by games and content applications where users want to share an image or video clip. (Pi Network)

There are many other practical possibilities.

Marketplace applications

A buyer could share:

product images
receipts
delivery evidence
damaged-item photographs
dispute documentation

Content applications

A creator could share:

generated images
short videos
certificates
visual content
exported designs

Games

Players could share:

screenshots
achievements
short gameplay clips
result cards

Education applications

Students could share:

certificates
completed assignments
generated documents
project media

Community applications

Users could share:

event posters
images
short videos
community content

The important design principle is that the developer does not have to recreate the phone's sharing experience from scratch.

The new documentation may be just as important as the APIs

The technical features are the visible part of this update.

The documentation change may have a larger effect on developers over time.

Pi says its developer resources were previously spread across several destinations, including SDK documentation, the Community Developer Guide, and a GitHub documentation repository. The new documentation consolidates these resources under a Pi-owned domain and organizes them around the developer journey. (Pi Network)

The new documentation is now structured around areas such as:

building your first Pi App
getting started
app registration
environments
authentication
payments
ads
native features
API references
concepts
troubleshooting and support (Pi Docs)

That structure is considerably more useful than forcing a new developer to discover individual documentation sources independently.

The developer journey is becoming clearer

The current documentation essentially gives developers a path like this:

Set up accounts
      ↓
Register the app
      ↓
Choose Testnet / Mainnet environment
      ↓
Build the application
      ↓
Integrate Pi SDK
      ↓
Add authentication
      ↓
Add payments or native features
      ↓
Test in Sandbox
      ↓
Prepare for launch

That is the right mental model for a platform SDK.

Developers do not usually struggle because they cannot understand what an API endpoint does.

They struggle because they do not know:

where to begin
what needs to be registered
which environment to use
what belongs on the frontend
what belongs on the backend
how authentication should be verified
how payments should be completed
which features require Pi Browser
how to move from testing to production

The new documentation is designed to address those gaps. (Pi Network)

Authentication still belongs to the backend

One area where developers should be particularly careful is authentication.

The Pi SDK can start the authentication flow in the browser, but the backend remains responsible for verifying the user's identity.

The current SDK documentation explicitly states that developers should use the Platform API as the source of truth on the backend and verify the access token through the /me endpoint. Server-side credentials should also never be exposed in client-side code. (Pi Docs)

A safer architecture looks like this:

Pi Browser
    |
    | Pi.authenticate()
    v
Pi App
    |
    | access token
    v
Your Backend
    |
    | verify token
    v
Pi Platform API
    |
    v
Verified user

The frontend can use the returned user information for presentation, but important application decisions should not rely solely on unverified client-side data.

This becomes especially important when the application has:

payments
account-specific permissions
valuable digital assets
rewards
private data
user-specific business logic

Payments are still a backend responsibility

The same principle applies to payments.

Pi's current SDK documentation separates the client-side payment flow from server-side approval and completion. Pi.createPayment() starts the user payment experience, but the backend is responsible for server-side approval and completion. (Pi Docs)

A simplified flow looks like:

User
  |
  v
Pi.createPayment()
  |
  v
Payment created
  |
  v
Backend approval
  |
  v
User submits transaction
  |
  v
Backend completion
  |
  v
Application records the result

This distinction is important for developers coming from conventional Web2 payment integrations.

The browser initiating a payment does not mean the browser should be trusted to decide that the payment is complete.

Pi's documentation also accounts for incomplete payments, including situations where a blockchain transaction has been submitted but developer-side completion has not yet occurred. (Pi Docs)

For production applications, payment state should therefore be treated as a proper backend workflow rather than a simple frontend callback.

The Pi SDK is broader than payments

It is easy to think of the Pi SDK primarily as a way to authenticate users and accept Pi.

The current documentation shows a wider set of capabilities.

The SDK includes support for:

authentication
payments
ads
wallet-related functionality
native Pi Browser features
share functionality
feature detection

The documentation also provides a Pi.nativeFeaturesList() method that lets an application determine which native capabilities are available in the Pi Browser version being used. (Pi Docs)

That is particularly useful when building applications that need to behave differently depending on the user's environment.

Instead of assuming that every Pi Browser installation supports every capability, an app can check what is available and adapt its interface accordingly.

A practical architecture for a Pi App

With these capabilities in mind, a modern Pi App does not need to put everything into one layer.

A cleaner architecture might look like this:

                    Pi Browser
                        |
          +-------------+-------------+
          |             |             |
     Pi SDK        Local Storage   Native Share
          |                           |
          v                           v
      Authentication              Device sharing
          |
          v
      Your Backend
          |
    +-----+------+----------------+
    |            |                |
 Database    Pi Platform API   Application Logic
    |            |                |
    |       User verification     |
    |       Payments              |
    |       Staking data          |
    |                              |
    +------------------------------+

Each layer has a job.

Pi SDK

Starts user-facing Pi interactions.

Local storage

Keeps appropriate lightweight state on the device.

Native sharing

Connects application content with the device's sharing system.

Backend

Handles trusted application logic, persistence, authentication verification, payment processing, and integrations.

Pi Platform APIs

Provide the Pi-specific services required by the application.

That separation makes the application easier to reason about and reduces the temptation to put sensitive logic into the browser.

What developers should not do

New capabilities often create more possibilities, but they also create new ways to build an application incorrectly.

Do not use local storage as permanent application storage

Local data can be removed and does not automatically follow a user across devices. (Pi Network)

Do not trust client-side authentication data as your backend source of truth

Verify the access token server-side through the appropriate Platform API flow. (Pi Docs)

Do not expose your Server API Key

Pi's documentation explicitly warns against putting server-side credentials in client-side code. (Pi Docs)

Do not treat staking as a universal reputation score

Staking data is an application-specific signal. The product logic around it still needs to be designed carefully.

Do not assume every feature works everywhere

Pi's native capabilities can depend on the user's Pi Browser environment. Feature detection exists for a reason. (Pi Docs)

Do not build the payment system around the frontend alone

Approval and completion belong in the backend workflow. (Pi Docs)

How the new capabilities change the types of apps developers can build

The individual features become more interesting when combined.

Consider a community marketplace.

A Pioneer signs in using Pi authentication.

The application stores temporary filters and preferences locally.

The user purchases an item using Pi.

The backend verifies and completes the payment.

The marketplace uses app-specific staking information as one input into a community participation feature.

The buyer receives a product and needs to report a problem.

They attach or share images through the native file-sharing experience.

That is no longer simply a website with a cryptocurrency payment button.

It becomes an application that uses several parts of the Pi platform together.

A useful way to evaluate each Pi capability

Before integrating a new feature, developers can ask four questions:

Question	Why it matters
Does this data need to survive?	Determines local vs server storage
Does the server need to trust it?	Determines whether backend verification is required
Is it specific to the user or device?	Helps avoid synchronization problems
Does it improve an actual workflow?	Prevents adding features just because an API exists

This sounds obvious, but it is one of the easiest ways to avoid overengineering.

A developer does not need to use every Pi capability.

The better application is usually the one that uses the smallest set of platform features necessary to create a good experience.

What this means for developers coming from Web2

Pi's current documentation deliberately lowers the amount of blockchain-specific knowledge required to build an application.

The platform is designed around familiar web development concepts while exposing Pi-specific capabilities through its SDK and APIs. Pi's developer platform describes the SDK and APIs as tools that allow developers to integrate applications with Pi without requiring specialized blockchain programming experience. (Pi Network)

For a JavaScript or full-stack developer, the workflow can therefore feel much closer to building a conventional web application than implementing a blockchain protocol from scratch.

The difference is in the integration points.

You still build:

Frontend
Backend
Database
Authentication
Business logic
APIs

But you can additionally integrate:

Pi authentication
Pi payments
Pi wallet functionality
Pi ads
Pi native features
Pi ecosystem data

That is where the platform becomes useful for application developers who are not blockchain specialists.

The new documentation also makes the first project easier to approach

The current documentation recommends starting with the first Pi App flow, followed by a working app with authentication and payments, before moving into individual platform capabilities. (Pi Docs)

The official documentation also provides a Demo App as an open-source reference implementation, giving developers something concrete to inspect rather than learning everything from isolated API references. (Pi Docs)

For someone building their first Pi App, that is a much better starting point than trying to understand the entire SDK before writing any code.

A sensible progression is:

1. Register the app
2. Run the Demo App
3. Connect the SDK
4. Implement authentication
5. Verify authentication on the backend
6. Add the feature your product actually needs
7. Test in Sandbox
8. Handle failure states
9. Test payments if required
10. Prepare the production environment

The documentation currently provides dedicated sections for registration, environments, authentication, payments, ads, native features, API references, concepts, and troubleshooting. (Pi Docs)

Where these updates are most useful

Not every application needs every new capability.

App type	Local storage	Staking API	File sharing
Marketplace	High	Potentially useful	High
Social/community app	High	Potentially useful	High
Game	High	Potentially useful	High
Content app	High	Potentially useful	High
Utility app	High	Depends on product	Medium
Payment-focused app	Medium	Depends on product	Low to medium
Simple information app	High	Usually unnecessary	Low

The most interesting applications will probably be the ones that combine these capabilities with an actual product need rather than exposing the APIs as features for their own sake.

The bigger developer story

The significance of this update is not really the number of new APIs.

It is the direction of the platform.

Pi is adding more pieces that developers normally need when turning a basic web application into a complete product:

Identity
   +
Payments
   +
Storage
   +
Ecosystem signals
   +
Native device interaction
   +
Documentation

Local storage addresses lightweight client-side state.

The Staking Data API gives applications access to an app-specific ecosystem signal.

File sharing connects Pi Apps more naturally with the device.

The documentation consolidation addresses a different problem altogether: developer friction.

Pi's own explanation is that these tools are intended to reduce practical barriers to building and maintaining applications while expanding the types of products developers can create within the ecosystem. (Pi Network)

For developers, that makes the most useful question less about which new API is interesting and more about which part of the user journey is currently difficult to build.

If it is temporary state, local storage may help.

If it is application-specific staking participation, the Staking Data API may be relevant.

If it is getting content from the app into another application, native file sharing may solve the problem.

If the problem is simply figuring out how the Pi platform fits together, the new documentation is now the place to start. (Pi Docs)
