🎉 We are so happy to announce the release of ink! v5! 🎉
A big theme of this release is the
@Polkadot
treasury-funded security review of ink! by
@OpenZeppelin
. It resulted in recommendations that we've now implemented. Plus a large number of other cool things!
More below! 🧵👇
🦑 ink! contracts can now be deployed on

Congratulations to the entire
@Aleph__Zero
team and anyone else who contributed!
We are very much looking forward to the potential that is unleashed today!
We've released ink! 4.0 & made some *ink!redible* updates and changes🦑
Be sure to read all about the big themes from this release and tell us which change you're most excited about:

Hey everyone! If you haven’t seen so already, OpenZeppelin (OZ), a leader in the smart contract security auditing space, just dropped their security assessment report for their recent work on ink! 📝
In case you don’t want to read the whole report, here’s a tl;dr 🧵
OpenZeppelin was asked to conduct a security review of

by the
@Polkadot
treasury. ink! is a Rust domain-specific language for writing smart contracts for Polkadot parachains.

🛠️ We just published cargo-contract v3.0!
cargo-contract is our command-line tool to build, deploy & interact with ink! smart contracts. Since ink! is just
#Rust
, our tool is mostly a wrapper around cargo, ensuring that contracts are build with the best combination of flags.
We wish you all happy holidays! We're excited for the new year and have great things planned ‒ starting with our next major release ink! 4.0 early next year.
Hello, Twitter! To start off this account we have something to celebrate right away: The ink! repository has reached 1k stars on GitHub! To celebrate this we've published an article explaining what ink! is: .
