Polygon Labs will no longer accept contributions to its Edge framework (also known as Supernets), instead focusing on the expansion of Chain Development Kit (CDK).

Edge, which was initially developed as an open-source tool under the Apache License 2.0, facilitated the creation of custom Ethereum-compatible blockchain networks. However, the team’s development priorities have shifted in the last year, according to a statement.

Instead of continuing with Edge, the firm’s toolkit designed for the development of various Layer 2 ZK-Rollups — Layer 2 networks designed using zero-knowledge proofs — will now be the focus. Chains deployed with the CDK are expected to be interoperable across a large network.

Polygon CDK over Edge Several projects, including Immutable, OKX, and others Astar, Canto, Palm Network, Aavegotchi, IDEX, Nubank, and Manta Network have expressed interest in or plans to use the Polygon CDK for Layer 2 network development.

“Polygon CDK-deployed chains will be interoperable within the CDK ecosystem’s broader web of ZK-powered L2s, creating a single unified pool of liquidity.” “These are features that Edge does not natively support and will necessitate migration with significant modifications,” Polygon Labs said in a statement shared with The Block.

The project currently employs two primary scaling methods: a Polygon PoS sidechain and a zkEVM zero-knowledge rollup network.

The 2.0 upgrade, an ecosystem comprised of multiple chains enhanced with zero-knowledge capabilities, is a major development focus for Polygon Labs. This CDK-powered ecosystem, set to launch in 2024, aims to integrate Layer 2 chains based on ZK rollups and facilitate cross-chain communication.
