According to official sources, Swell L2, a re-collateralization agreement, announced on October 29 that it will migrate to the Optimism Superchain as an Optimistic Rollup based on the OP Stack. After this migration, Swell L2 will provide re-collateralization income and security support to the Superchain through its unique re-collateralization proof mechanism.

To meet the requirements of the Superchain, Swell L2 will make adjustments to its design, including using ETH as the gas token for rollup and donating some of the sorter revenue to the Optimism Collective. Swell L2 had already reached a total locked position (TVL) of $1 billion during its pre-release phase.
