* Test defining an RPC API * Add wrapper clients for the RPC API * Implement most Ethereum RPCs Does not include RPCs that require the bridge contract. * Implement a few of the Substrate RPCs Still missing proper error handling, as well as decoding responses from the Substrate node. * Make error handling more ergonomic * Implement Substrate RPCs that use `state_call` * Implement rest of Substrate RPCs * Implement `eth_call` RPC This can be used to implement higher level requests like fetching Substrate headers from an Ethereum node. * Build some of the higher level Ethereum RPCs Uses the new Ethereum RPC interface to do so * Build some of the higher level Substrate RPCs * Remove old Ethereum RPC methods * Remove old Substrate RPC methods * Add some documentation to Substrate RPCs * Fix typo in enum construction * Revert commits `0f0435d` to `ca75502` This range of commits was mainly trying to integrate the new RPC interface into the existing codebase, however this turned out to be a little out of scope for the current PR. Instead this work will be incorporated into a PR which aims to close #72. * Add documentation to RPCs * Rename functions in RPC API to conform to snake_case * Check that header contains a number and hash * Put doc comments on trait instead of impl methods * Remove expect() calls * Replace runtime API enums with consts * Accept Bytes when submitting extrinsic Let's us avoid using a runtime specific Extrinsic. * Add strictly typed arguments to RPC API Missing two methods right now, which require a `serde::Deserialize` implemenation before they can be changed. * Add `chain_getBlock` Substrate RPC * Use typed arguments for `eth_estimateGas` and `eth_call` * Silence dead code warnings * Add check for logs bloom * Remove unused variables * Add documentation to RPC error enums
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.
