| # Monthly Update: Parity Smart Contracts | ||
|
|
||
| ## What is this? | ||
| Hey there reader 👋! | ||
|
|
||
| This is meant to be a high-level overview of the changes that have taken place as part of | ||
| Parity's Web Assembly (Wasm) smart contract efforts. These efforts include the [`ink!`](https://github.com/paritytech/ink) | ||
| programming language, the [`pallet-contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts) execution environment, the [`cargo-contract`](https://github.com/paritytech/cargo-contract) | ||
| development tool, and the [Canvas parachain](https://github.com/paritytech/cumulus/tree/master/polkadot-parachains/canvas-kusama). For anything UI related go check out the | ||
| [`contracts-ui` repository](https://github.com/paritytech/contracts-ui). | ||
|
|
||
| If these updates are too high-level for you you can always check out the release notes for | ||
| the various projects: | ||
| - [`ink!`](https://github.com/paritytech/ink/blob/master/RELEASES.md) | ||
| - [`pallet-contracts`](https://github.com/paritytech/substrate/blob/master/frame/contracts/CHANGELOG.md) | ||
| - [`cargo-contract`](https://github.com/paritytech/cargo-contract/blob/master/CHANGELOG.md) | ||
|
|
||
| If you're new here and aren't sure where to get started with ink! check out our | ||
| [guided tutorial for beginners](https://docs.substrate.io/tutorials/v3/ink-workshop/pt1/). | ||
|
|
||
| This was inspired by the [Polkadot Staking Progress Report](https://gist.github.com/kianenigma/aa835946455b9a3f167821b9d05ba376) ❤️. | ||

||
| ## April 2022 | ||
|
|
||
| ### Releases 🆕 | ||
|
|
||
| For ink! we released [v3.0.1](https://github.com/paritytech/ink/releases/tag/v3.0.1) with | ||
| minor bugfixes. Besides that we made a number of improvements to our examples ‒ mostly to | ||
| our [upgradeable contracts examples](https://github.com/paritytech/ink/tree/master/examples/upgradeable-contracts). | ||
|
|
||
| For [`cargo-contract`](https://github.com/paritytech/cargo-contract) we released | ||
| [v1.1.1](https://github.com/paritytech/cargo-contract/releases/tag/v1.1.1) and | ||
| [v1.2.0](https://github.com/paritytech/cargo-contract/releases/tag/v1.2.0) | ||
| with bug fixes, a new sub-command `decode`, and improved support for the `call` and | ||
| `instantiate` sub-commands. | ||
|
|
||
| For tutorials, development and testing we recommend using our | ||
| [`substrate-contracts-node`](https://github.com/paritytech/substrate-contracts-node). | ||
| We issued the release [v0.13.0](https://github.com/paritytech/substrate-contracts-node/releases/tag/v0.13.0), | ||
| which is in sync with a recent Substrate `master` (see the release notes for the specific commit hash). | ||
| Pre-built binaries for the release are available for Linux and Mac. | ||
|
|
||
| ### Community Badges 🙌 | ||
|
|
||
| We've added two versions of a community badge. | ||
|
|
||
| If you have a public repository with an ink! contract it would be awesome | ||
| if you could add one of those! | ||

| ### Team Retreat in Athens 🇬🇷 | ||
|
|
||
| We ‒ the developers working on ink!, Substrate's [`pallet-contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts), | ||
| and the [Contracts UI](https://github.com/paritytech/contracts-ui) ‒ | ||
| went on a team retreat in April. We discussed our roadmap for the rest | ||
| of this year, as well as some technical designs of how we want to implement | ||
| e.g. XCM in ink!. We're normally working across different time zones, with | ||
| some of us embracing the digital nomad lifestyle. Hence it was very | ||
| productive to gather together for a week. | ||
|
|
||
| We also did a little hackathon to do some dog-fooding: we've built a | ||
| Dapp that makes use of all components by the above teams. We plan | ||
| to open source it soon, stay tuned for that 😎. | ||
|
|
||
| There's a lot on the horizon and we're enthusiastic about the rest of this year! | ||
|

| ### Spanish Twitter Space 🐦 | ||
|
|
||
| [Hernando](https://github.com/hcastano) was a guest at the spanish Polkadot | ||
| Twitter Space. The space has been recorded: | ||

||
| The network connection of the organizer had a bad day, hence it's two | ||
| recordings. | ||
|
|
||
| ### StackExchange Public Beta | ||
|
|
||
| The [Substrate & Polkadot StackExchange](https://substrate.stackexchange.com/) site | ||
| has graduated from its private beta ‒ the site is now in public beta! | ||
|
|
||
| This means that the site is now indexed by search engines and can be | ||
| browser without any user account. | ||
|
|
||
| If you have any questions regarding ink! or smart contracts on Substrate this is | ||
| the place to be. | ||
|
|
||
| ### Canvas Update | ||
|
|
||
| You may know that we were working on a common good smart contracts parachain | ||
| named Canvas. We've decided to put this project on hold. This gives us more | ||
| room to make ink! and the [`pallet-contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts) | ||
| as competitive as possible, as well as help parachain teams include those. | ||
| This is not to say that we'll never get back to Canvas, but as of right now | ||
| we're no longer working on this project. | ||
|
|
||
| ## March 2022 | ||
|
|
||
| ### StackExchange Beta | ||
|
|
||
| We are participating in the Beta of [the Substrate StackExchange](https://substrate.stackexchange.com/) site! | ||
|
|
||
| If this StackExchange site gains traction it will be made available to the general public. | ||
| To reach this goal it's important to have the community engage there though. | ||
|
|
||
| Head over to [substrate.stackexchange.com](https://substrate.stackexchange.com/) | ||
| to ask us any questions (there is an `ink` tag)! | ||
|
|
||
| ### ink! 3.0 🦑 | ||
| The star of the show this month is the release of ink! 3.0: | ||
|
|
||
| - You can find the release notes [here](https://github.com/paritytech/ink/releases/tag/v3.0.0). | ||
| - We've also published a blog post with some more context:<br> | ||
| [ink! 3.0: Parity’s Rust-Based Language for WASM Smart Contracts Gets a Major Update](https://www.parity.io/blog/ink-3-0-paritys-rust-based-language-gets-a-major-update). | ||
|
|
||
| The team has been working on this release for a while. If you're a developer you're | ||
| probably aware of this thanks to the long list of release candidates (`v3.0.0-rcX`) we've | ||
| pushed out in preparation for the stable 3.0 release. | ||
|
|
||
| The main idea behind ink! 3.0 is that it's just Rust. The syntax is pretty much | ||
| identical, and all the tooling you know and love, such as `rust-analyzer` and Clippy, | ||
| just works. | ||
|
|
||
| Some other included changes worth highlighting: | ||
| - Reduced contract sizes for better performance in a parachain context. | ||
| - Support for cross-contract calls, making it easier to write complex applications. | ||
| - Trait support, allowing for a more Rusty development experience. | ||
|
|
||
| ### cargo-contract 1.0 | ||
| Alongside the release of ink! 3.0 we're also releasing [`cargo-contract`](https://github.com/paritytech/cargo-contract) in | ||
| its first stable version 1.0. | ||
| `cargo-contract` is a handy developer tool for building, testing, and deploying ink! | ||
| contracts. | ||
|
|
||
| Some notable updates in this release include: | ||
| - Support for uploading and calling contracts on a chain with `pallet-contracts`. | ||
| - Linting rules for ink! contracts, giving developers warnings about common errors. | ||
|
|
||
| ### Delegate Call | ||
| Another update worth pointing out is the addition of `delegate_call`. What this allows is | ||
| a way for contracts to forward a call they received to another contract. | ||
|
|
||
| One use case for this is implementing a [Proxy Upgrade Pattern](https://docs.openzeppelin.com/upgrades-plugins/1.x/proxies) for smart contracts. | ||
|
|
||
| ``` | ||
| User ---- tx ---> Proxy ----------> Implementation_v0 | ||
| | | ||
| ------------> Implementation_v1 | ||
| | | ||
| ------------> Implementation_v2 | ||
| ``` | ||
|
|
||
| This required some work in both `pallet-contracts` and ink!. Shoutout to the team over | ||
| at [Supercolony](https://supercolony.net/) for driving the development here! | ||
|
|
||
| We now have two example contracts for writing upgradeable contracts in ink!. | ||
| [See here](https://github.com/paritytech/ink/tree/master/examples/upgradeable-contracts) | ||
| for a deeper explanation. | ||
|
|
||
| ### Workshop & Talk at EthDenver | ||
|
|
||
| [Hernando](https://github.com/hcastano) and [Achim](https://github.com/achimcc) went to EthDenver to | ||
| give a workshop and talk regarding ink! on the Substrate stage! | ||
|
|
||
| The recording is available [here](https://www.youtube.com/watch?t=7122&v=NrG3co6UWEg). | ||
| The monthly update has been moved to [https://ink.substrate.io/monthly-update](https://ink.substrate.io/monthly-update)! |
