The Swell Drops Polygon CDK Liquid Recovery Protocol for OP Stack

The liquid recovery protocol Swell has announced that its Layer 2 is migrating to the Optimism superchain.

Swell said it would move away from the Polygon Chain Development Kit (CDK) as part of this strategic transition.

According to the official blog post, Swell is willing to provide security features and recovery performance for Superchain, using its Proof of Restake model to improve the capital efficiency of staked assets and establish a growth support mechanism.

To comply with Superchain requirements, Swell Layer 2 will introduce modifications, such as using ETH as a token for accumulated gas and directing a portion of sequencer earnings to the Optimisme collective.

In a statement, Swell founder Daniel Dizon said:

“The Superchain is home to DeFi’s biggest success stories, with 4 of the top 5 chains using Optimism’s OP Stack. Swell is excited to partner with OP Labs and the wider Optimism Collective to build on our shared vision to scale Ethereum and make Swell L2 the home of all Superchain restoration activity.”

With the latest development, Swell will join a growing list of prominent players in the crypto industry, including major exchanges such as Coinbase, by integrating with Optimism Superchain via the OP Stack framework.

Kraken recently announced its own Layer 2 network, Ink, built on the OP Stack to be part of the Superchain. Other notable names already using the OP Stack include Uniswap, a leading decentralized exchange, and Sony, a global electronics leader.

Swell previously announced plans to use Polygon’s AltLayer-compatible CDK to build a zkEVM for its Layer 2 network. However, the decision to leverage Optimism’s OP Stack in Polygon’s CDK site. Despite this, Swell said he “continues to believe in the aggregated ecosystem that Polygon is building.”

Meanwhile, DefiLlama data shows that Swell products collectively have a total locked value of more than $1.35 billion.

Polygon Chain Development Kit (CDK)

Polygon Labs introduced the Polygon Chain Development Kit (CDK), an open source framework, in the third quarter of 2023. It was designed to enable the release of ZK Layer 2 and support the transition from EVM Layer 1 to layer 2. Polygon CDK focuses on customization and zero-knowledge (ZK) technology, and ultimately aims to streamline connections between CDK-based chains and the AggLayer.

Several popular projects, including OKX, Ronin, Immutable, Moonveil, Fox, Witness Chain, Silicon, Manta, Hypr Network, Flipkart, Libre, Arianee, Gnosis Pay, Ton Applications Chain (TAC), and WireX, have announced CDK-based chains.
