ChainCatcher news, according to official Starknet information, the total number of active Cairo developers on GitHub reached a new high since January 2023 in September 2024.

Starknet ecosystem smart contract wallet Braavos stated on social media that to receive the Starknet airdrop, users must upgrade their accounts to Cairo2.It is reported that this upgrade includes features such as using STRK to pay gas fees.

ChainCatcher news, Starknet has released a new version Cairo v2.5.0, which only involves changes to the high-level compiler (from Cairo to Sierra), and can be deployed immediately on the Starknet testnet and mainnet.It is reported that this version also introduces various features of Sierra, eliminates many limitations present in match expressions, introduces a more user-friendly loop syntax, adds the concept of pub, and more.

ChainCatcher news, OKX Ventures announced an investment in Kakarot. It is reported that Kakarot is a 2.5 class ZkEVM written in the Turing-complete programming language Cairo, currently launching its first test network, which will operate as L2 on Ethereum or L3 on StarkNet. After this initial phase, Kakarot plans to become a 1 class ZkEVM, enabling any L1 node to generate Stark Proofs. Additionally, Kakarot is currently exploring other ZKPs, account abstraction, and scaling solutions to promote the growth and resilience of the Web3 space.Dora, the founder of OKX Ventures, stated, "Kakarot is built on Starknet, using an innovative language development form, addressing the issue of Starknet's incompatibility with EVM, allowing the Ethereum ecosystem to thrive on Starknet."

ChainCatcher message, Starknet stated on social media that Cairo V2.3.0 has transitioned from a candidate release to a formal release. The new version includes performance improvements, bug fixes, and a new inline macro to help manage component dependencies.Previously, Starknet announced that its programming language Cairo V2.3.0 version introduced components.

ChainCatcher news, StarkWare today released the roadmap for the programming language Cairo. The V2 version of Cairo is set to be released, and the team expects to launch the new contract syntax alongside Starknet alpha v0.12.0.StarkWare stated that Cairo is now stable and rich enough to support complex applications and to port existing Cairo 0 logic. In addition, Starknet's backward compatibility guarantee ensures that even if there are significant changes to the language, users will have sufficient time (at least six months) to complete the development or review and deployment of contracts.

ChainCatcher news, the Ethereum Layer 2 network Starknet announced that the mainnet is now running on version v0.11.2, with the main update being the activation of its programming language Cairo 1. Users can now deploy Cairo 1 contracts on the mainnet. (Source link)

ChainCatcher message, the documentation of The Cairo Programming Language Book created by the Cairo language community and contributors has been released, explaining concepts of Cairo, common programming concepts, Cairo's ownership system, Cairo function testing, and more. (source link)

ChainCatcher news, the Ethereum Layer2 scaling solution Starknet has launched the Starknet Alpha v0.11.0 version on the testnet. This version update includes support for developers to deploy Cairo 1.0 contracts, replacement of class system calls, and a 5x reduction in computation costs. (Source link)

ChainCatcher news, the one-stop Web3.0 security development environment and developer platform Hamster has announced comprehensive integration and compatibility with the Layer2 network StarkNet. So far, Hamster has successfully integrated multiple contract templates based on the Cairo language and has opened a one-stop node deployment RPC service for the StarkNet network. Meanwhile, the Hamster team is actively developing development solutions for ZK Rollup, modularizing and tooling the ZK Solution to help developers get started and onboard quickly. As a one-stop developer platform infrastructure, Hamster's comprehensive integration and compatibility with the StarkNet network will significantly lower the barriers for developers to enter StarkNet network development, contributing to ecological prosperity.

ChainCatcher news, the StarkRocks team from the StarkNet ecosystem NFT project will rewrite the StarkRock contract in Cairo 1.0, taking a snapshot of Rock holders' wallets and airdropping new Rock NFTs to those wallets.It is reported that StarkWare has released the first public version of Cairo 1.0, and the NFT contracts on the StarkNet mainnet need to be rewritten in Cairo 1.0 after the state reset. Users do not need to take any action; after the state reset, old NFTs will become invalid and cannot be sold, purchased, or transferred. (source link)

ChainCatcher news, StarkWare announced the open sourcing of its programming language Cairo 1.0, as the first step in open sourcing the StarkNet stack. StarkNet does not yet support Cairo 1.0, which will be supported in the first quarter of next year. The first version of the Cairo 1.0 compiler is planned to be released in early next year, focusing on supporting all existing features of StarkNet in Cairo 1.0, and is also expanding the capabilities of the Cairo 1.0 compiler.

ChainCatcher news, zero-knowledge proof technology development company StarkWare announced on Twitter that it has completed the ZK-EVM using the STARK proof system programming language Cairo, and will invite Ethereum co-founder Vitalik Buterin, ZK-STARK co-inventor Eli Ben-Sasson, and StarkWare member Shahar Papini to a Twitter Space tomorrow. It is reported that Cairo is a Turing-complete zero-knowledge proof system language and is still in the early stages of development. (source link)

ChainCatcher news, StarkWare President Eli Ben-Sasson revealed that their L2 scaling solutions StarkEx and StarkNet are approaching two significant milestones: first, the release of the upgraded native smart contract language for StarkNet, Cairo 1.0, which has now been completed and is expected to launch by the end of 2022; afterward, the team will also restart StarkNet on the Ethereum mainnet, named "Regensis," aimed at improving network DoS attack protection and reducing gas fees.In addition, Eli Ben-Sasson stated that the originally scheduled native token issuance plan for September has been postponed because they want to improve their work on Solidity contracts, so the StarkWare native token will go live within October. However, Eli Ben-Sasson pointed out that they will not provide free tokens to users in the initial phase, and all tokens will be locked immediately after the release.Eli Ben-Sasson also revealed that StarkWare will soon announce the establishment of a foundation responsible for token allocation and distribution.

Chain Catcher news, Ethereum client Nethermind has announced that the next significant milestone of the Warp project has been achieved, successfully translating and compiling Uniswap V3 into Uniswap V3 Warped (UniStark). A hardhat plugin is currently being completed, allowing all Solidity hardhat tests to run on the translated Cairo. This means that Warp has converted and deployed every Solidity file in the Uniswap V3 repository with minimal changes to the source code.It is reported that on June 21 of this year, the Ethereum client Nethermind launched the translator Warp 2.0. Warp 2.0 supports converting Solidity contracts to Cairo for deployment on StarkNet. (Source link)

According to Chain Catcher news, StarkNet announced plans for a mainnet reset after the launch of the programming language Cairo 1.0 to ensure a smooth migration for users. Additionally, during the transition period, developers will need to port their code to Cairo 1.0, and regular users will need to upgrade their accounts and update their wallets. The team expects Cairo 1.0 to be released by the end of 2022. (Source link)
