NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Westend and Rococo test networks. Polkadot, Kusama and their system chain runtimes
are located in the runtimes
repository maintained by
the Polkadot Technical Fellowship.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
Releases
[!NOTE]
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.
The Polkadot-SDK has two release channels: stable
and nightly
. Production software is advised to only use stable
.
nightly
is meant for tinkerers to try out the latest features. The detailed release process is described in
RELEASE.md.
Stable
stable
releases have a support duration of three months. In this period, the release will not have any breaking
changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week
cadence.
Nightly
nightly
releases are released every night from the master
branch, potentially with breaking changes. They have
pre-release version numbers in the format major.0.0-nightlyYYMMDD
.

Skip Feeless Payment Pallet
This pallet allows runtimes that include it to skip payment of transaction fees for
dispatchables marked by #[pallet::feeless_if]
(macro@ frame_support::pallet_prelude::feeless_if
).
Overview
It does this by wrapping an existing SignedExtension
implementation (e.g.
pallet-transaction-payment
) and checking if the dispatchable is feeless before applying the
wrapped extension. If the dispatchable is indeed feeless, the extension is skipped and a custom
event is emitted instead. Otherwise, the extension is applied as usual.
Integration
This pallet wraps an existing transaction payment pallet. This means you should both pallets
in your construct_runtime
macro and include this pallet's
SignedExtension
(SkipCheckIfFeeless
) that would accept the existing one as an argument.
