Just follow the preceding link. Looking for developer documentation? Then you are at the right place.This is an effort to provide a collection of tools, utilities and libraries for interacting with the Polkadot network from JavaScript. All code is made available on GitHub with a permissive Apache-2.0 license.While there is a slant towards developer tools, providing libraries to allow others to build tools on top of, a collection of applications are made available that allows for interaction with the network from a pure user perspective. The documentation contained here has a focus on the developer libraries.If you are a end-user looking to interact with the network, you can interact with Polkadot/Substrate (latest, project hosted) or IPFS (stable, weekly releases).Help us help othersIf you spot gaps in the information provided, or are uncertain about any specific area, please do log an issue or if you are that way inclined, make a pull-request. We really want to have good documentation in these areas and allow people to be productive right from the start.ContributingThis is a community effort to trial tooling while the network is being developed. Contributions are welcome. Feel free to use the tools and libraries, log issues as you find them or create pull requests for your bug-bears or features.As a new collection of projects, we take quality seriously - library code should be comprehensively unit tested and interfaces should have full type definitions.Edit this pageNextOverviewHelp us help othersContributing

Connecting to Polkadot gives you the ability to interoperate with a wide variety of blockchains in the Polkadot network.Economic & transactional scalabilityPolkadot provides unprecedented economic scalability by enabling a common set of validators to secure multiple blockchains. Polkadot provides transactional scalability by spreading transactions across multiple parallel blockchains.Easy blockchain innovationCreate a custom blockchain in minutes using the Substrate↗ framework. Connect your chain to Polkadot and get interoperability and security from day one. This ease of development helps Polkadot’s network grow.High energy efficiencyPolkadot consumes a small fraction of the energy used by conventional blockchains thanks to its next-generation nominated proof-of-stake (NPoS) model. Using the equivalent of ~6.6 US households worth of energy per year, Polkadot has the lowest carbon footprint↗ among proof-of-stake protocols analyzed in recent research↗.Security for everyonePolkadot's novel data availability and validity scheme allows chains to interact with each other in a meaningful way. Chains remain independent in their governance, but united in their security.User-driven governancePolkadot has a sophisticated governance system where all stakeholders have a voice. Network upgrades are coordinated on-chain and enacted autonomously and without forking the network, ensuring that Polkadot’s development remains future-proof and community-driven.Learn more about Polkadot’s technologyDiscover PolkadotPowering the Polkadot networkThe DOT token serves three distinct purposes: governance over the network, staking and bonding.GovernancePolkadot token holders have complete control over the protocol. All privileges, which on other platforms are exclusive to miners will be given to the Relay Chain participants (DOT holders), including managing exceptional events such as protocol upgrades and fixes.StakingToken holders keep the network secure and collect rewards by staking DOT. Polkadot’s advanced staking system is designed for maximum decentralization and fair representation, rewarding good actors and punishing bad actors to ensure network security.BondingNew parachains are added by bonding tokens. Outdated or non-useful parachains are removed by removing bonded tokens. This is a form of proof of stake.Learn more about DOT and stakingDiscover DOTLearn stakingAn open-source protocol built for everyonePolkadot is an open-source project founded by the Web3 Foundation↗.Web3 Foundation has commissioned five teams and over 100 developers to build Polkadot, including:ChainSafeParity TechnologiesPolkadot JSSoramitsuFounded by some of the blockchain industry’s foremost buildersLearn moreFrom the blogDevelopersThe Polkadot Alpha Program: A New Era of Collaborative BuildingThe Polkadot Alpha Program is a new initiative the helps lower entry barriers for teams eager to build in the ecosystem.

Polkadot blockchain in a granular way. Below
we describe the different components of Polkadot-JS. For more information about Polkadot-JS you can
consult the official documentation.Polkadot-JS UIFor Developers and Power Users OnlyPlease note that this wallet UI is oriented toward developers and power users. Explore Polkadot with
a secure and user-friendly wallets listed on the
Polkadot website. If you need help using the
Polkadot-JS UI you can contact the
Polkadot Support Team.The Polkadot-JS UI is an application that loads in your browser. There is a standard DNS
hosted version, which always has the latest features, and an
IPFS version that is less frequently updated but is more decentralized.
This is also often referred to as Polkadot-JS Apps, UI or the Apps UI. In the Wiki pages we will
always refer to Polkadot-JS UI.Polkadot-JS Apps has many capabilities that go beyond basic wallet functions such as account
creation and sending or receiving transactions. See the dedicated section
for more information about the UI.Polkadot-JS UI Desktop AppThe Polkadot-JS UI also exists as a
desktop application for Windows, Mac and Linux.
The main advantage of using it is that by default it stores encrypted accounts on the filesystem
instead of browser's local storage. Local storage is susceptible to attacks using XSS (Cross-Site
Scripting). There's no such risk when with files stored on disk.The desktop app uses the Electron framework. It provides the same
features as web app, the only difference being different account storage.Ledger not supportedThe desktop application does not support Ledger accounts. If you need a cold storage solution you
can try Parity Signer (aka Polkadot Vault).Polkadot-JS ExtensionThe Polkadot-JS browser extension is not a wallet per se
but an account management tool. It allows you to create accounts and also import accounts from
Ledger devices or Parity Signer, allowing the signing of
extrinsics using these accounts. It also allows you export
existing accounts and restore accounts (given you have the required information to restore them).The extension is a robust key storage tool, i.e. even if you clear the cache of your browser your
accounts will be retained. The extension will recognize any websites that have been flagged for
malicious activity. For additional security, the extension will always ask if you want a specific
website to access the account information on it.The extension does not let users interact directly with on-chain functions as one would find on a
wallet app like Metamask, i.e. it does not allow you to transact or do anything else other than
adding and managing accounts. However, it provides a simple interface for interacting with
extension-compliant dApps such as the Polkadot-JS UI
and the Polkadot Staking Dashboard. Check
wallets and extensions page for wallets that are capable of
transacting on-chain directly.Metadata UpdatesThe browser extension is a tool that interacts with the Polkadot network, but it is disconnected
from it when it is not in use. It is important you
always check for metadata updates
before using the extension or other account management tools such as Parity Signer (aka Polkadot
Vault).Polkadot-JS Phishing ListThe Polkadot-JS phishing list website is a community-driven
curation of malicious actors and operators. The Polkadot-JS extension uses this list to warn a user
about suspicious URLs and addresses that are part of the list, and automatically blocks the account
address.Polkadot-JS APIThe Polkadot-JS API is a JavaScript API allowing for
programs to interface with the functionalities of
Polkadot.While interacting with the underlying
@polkadot/api, most interfaces are generated
automatically when connecting to an available node. This is quite a departure from many other API
designs where the interfaces are commonly static.When the API connects to a node, it initially retrieves the
metadata which is used to "decorate" the API based on
its contents. The metadata provides data in the form of api.
fits into one of the following categories:consts - runtime constants (these are not functions so the values are returned directly as they
are defined by the endpoint)query - chain state valuestx - all extrinsicsThe metadata also provides information on
events, which can be queried using the
api.query.system.events() interface.None of the information contained within the api.{consts, query, tx}.
are hard-coded in the API. These values are defined by the decoration applied from the initial
metadata response and are therefore completely dynamic. This suggests that when you connect to
different parachains, the metadata and API decoration will change and provide varying interfaces
based on the chain.A developer can use Polkadot-JS Apps to test code's functionality. Interacting with the Polkadot-JS
comes down to either querying on-chain data or
issuing an extrinsic.Querying On-chain DataTo populate the Apps UI, the web app queries the Polkadot-JS API. The API then queries a
Polkadot node and uses JavaScript to return
information that the UI will display on the screen. You can choose which node to connect to by
changing it in the upper-left-hand corner of the screen.Let's see how we can query on-chain data with Polkadot-JS UI on the Polkadot network with an
example. To find out the current value for existential deposit, navigate to Developer > Chain
state > Constants and query the balances pallet for existential deposit as shown in the snapshot
below. You need to click on the plus button to execute the query. The value displayed is in
plancksIssuing ExtrinsicsExtrinsics are pieces of information that come from outside the chain and are included in a block.
Extrinsics can be one of three types: inherents, signed, and unsigned transactions.Most extrinsics displayed on Polkadot-JS Apps are signed transactions. Inherits are non-signed and
non-gossiped pieces of information included in blocks by the block author, such as timestamps, which
are “true” because a sufficient number of validators have agreed about validity.Unsigned transactions are information that does not require a signature but will require some sort
of spam prevention, whereas signed transactions are issued by the originator account of a
transaction which contains a signature of that account, which will be subject to a fee to include it
on the chain.Edit this pageLast updated on Jan 4, 2024 by FilippoPreviousPolkadot-JSNextPolkadot-JS UIPolkadot-JS UIPolkadot-JS UI Desktop AppPolkadot-JS ExtensionPolkadot-JS Phishing ListPolkadot-JS APIQuerying On-chain DataIssuing Extrinsics© 2024 Web3 FoundationLegal DisclosuresDisclaimerPrivacy

A Portal into the Polkadot and Substrate networks. Provides a view and interaction layer from a browser.
This can be accessed as a hosted application via https://polkadot.js.org/apps/ or you can access the IPFS hosted version via https://polkadot.js.org/apps/ipfs (via hash) or https://dotapps.io (via ipns) to explore any of the supported Polkadot and Substrate chains.
If you run one or more IPFS node(s), pinning the UI (which only gets updated on releases) will make it faster for you and others. You can find details about that below in the IPFS chapter below.
Important If you are a chain developer and would like to add support for your chain to the UI, all the local configuration (API types, settings, logos) can be customized in the apps-config package, complete with instructions of what goes where.
Overview
The repo is split into a number of packages, each representing an application.
Development
Contributions are welcome!
To start off, this repo (along with others in the @polkadot family) uses yarn workspaces to organize the code. As such, after cloning dependencies should be installed via yarn, not via npm, the latter will result in broken dependencies.
To get started -
Clone the repo locally, via git clone https://github.com/polkadot-js/apps
Ensure that you have a recent LTS version of Node.js, for development purposes Node >= 16 is recommended.
Ensure that you have a recent version of Yarn, for development purposes Yarn >= 1.22 is required.
Install the dependencies by running yarn
Ready! Now you can launch the UI (assuming you have a local Polkadot Node running), via yarn run start
Access the UI via http://localhost:3000
Docker
You can run a docker container via -
docker run --rm -it --name polkadot-ui -e WS_URL=ws://someip:9944 -p 80:80 jacogr/polkadot-js-apps:latest
To build a docker container containing local changes -
docker build -t jacogr/polkadot-js-apps -f docker/Dockerfile .
When using these Docker commands, you can access the UI via http://localhost:80 (or just http://localhost)
IPFS
IPFS allows sharing files in a decentralized manner in a similar fashion the polkadot network exchanges blocks. IPFS works best when many nodes seed the same data. Nodes can seed specific data by pinning them.
You can pin with the following command:
curl -s https://polkadot.js.org/apps/ipfs/pin.json | jq -jr .IpfsHash | xargs -0 -I CID ipfs pin add --progress CID
Here is a script you can save as /usr/local/bin/polkadotjs-ipfs-pin.sh:
#!/usr/bin/env bash
IPFS='/usr/local/bin/ipfs'
curl -s https://polkadot.js.org/apps/ipfs/pin.json | jq -jr .IpfsHash | xargs -0 -I CID $IPFS pin add --progress CID
I suggest to run the script once. The output should be similar to (the CID/Hash will very likely be different though):
$ /usr/local/bin/polkadotjs-ipfs-pin.sh
pinned QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW recursively
Now that you know the CID (hash), you can check whether the data is already pinned or not:
$ ipfs pin ls | grep QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW
QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW recursive
Now that we know it works, we can automate that with a cron task. Run crontab -e.
If you see only comments, append the following to the file and save:
SHELL=/bin/bash
HOME=/
0 * * * * /usr/local/bin/polkadotjs-ipfs-pin.sh >/dev/null 2>&1
Now our script will run every hours at minute '0' (8:00, 9:00, etc...). To check, we can unpin temporarily:
$ ipfs pin rm QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW
unpinned QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW
Now asking for the CID confirms that is it not there.
$ ipfs pin ls QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW
Error: path 'QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW' is not pinned
Wait until the your cron task runs and try again:
$ ipfs pin ls QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW
QmNYAbzaE8kRAf68YiN3ZuUxgdwroeav3JhicsHsG5b2oW recursive
Tada! This is now automatic and you may forget it.
If you are curious and want to know how many people seed the UI on IPFS, here is the magic command (it may take a while to return the answer as ipfs will search for about 1 minute):
ipfs dht findprovs QmTejwB7mJPBHBoqubjzHSgSxfLMcjnZA3LFefqoQc87VJ | wc -l
If you are current about the content of what you just pinned, you may use the following command:
$ ipfs ls QmTejwB7mJPBHBoqubjzHSgSxfLMcjnZA3LFefqoQc87VJ

Desktop App
The main advantage of using Desktop App is that it by default stores encrypted accounts on the filesystem instead of browser's local storage.
Local storage is susceptible to attacks using XSS (Cross-Site Scripting). There's no such risk when with files stored on disk.
The desktop app uses the Electron framework. It provides the same features as web app, the only difference
being different account storage.
The accounts are stored in the following directories:
Mac: ~/Library/Application Support/polkadot-apps/polkadot-accounts
Linux: ~/.config/polkadot-apps/polkadot-accounts (or $XDG_CONFIG_HOME/polkadot-apps/polkadot-accounts if $XDG_CONFIG_HOME is defined)
Windows: %APPDATA%\polkadot-apps\polkadot-accounts
For more details on the desktop app, head over to Electron package README.
