PANews reported on October 30 that according to The Block, the liquidity re-pledge protocol Swell said it will join the Optimism superchain ecosystem by launching Optimism Rollup on OP Stack. Swell had previously planned a Layer2 chain using Polygon's chain development kit. The project stated: "As part of this strategic transformation, Swell will abandon Polygon CDK, but continue to believe in the aggregate ecosystem that Polygon is building."

As part of the partnership with OP Labs, the project will enter the Layer 2 Rollup superchain ecosystem along with Coinbase's Base, Kraken's Ink, Zora, Mode, SNAXchain, etc. Layer 2 is currently under development and a test network is expected to be launched soon. Swell's OP chain will use ETH as a gas token instead of rswETH as in the previous design. The project will allocate a portion of the sequencer revenue to the Optimism Collective, consistent with the plans of all chains in the superchain ecosystem.
