Swell shuts Swellchain; users must bridge funds by June 23

Swell is winding down Swellchain, its Optimism Superchain layer-2, and instructed users to bridge assets back to Ethereum by June 23 or face the possibility that funds will become unrecoverable. The company linked the decision to slower restaking adoption, lower Ethereum transaction fees and a strategic focus on its Faro product.

The project announced the Swellchain sunset on April 28 and set an initial withdrawal deadline of June 15. Deposits from Ethereum to Swellchain were disabled on May 5. The April update said the frontend withdrawal flow and bridge user interface would be retired after June 15, while the chain itself would continue to run until June 30. The post warned that users who missed the deadline might still recover funds only through manual contract interactions and that such recovery would require technical expertise.

On June 16 the team posted on X and updated its homepage with a June 23 deadline, stating the shutdown had begun and warning that anything left on Swellchain after that date would be unrecoverable. The project did not publicly explain why the public deadline changed from June 15 to June 23.

Users were directed to use the Superbridge to move assets back to Ethereum. The project emphasized that many on-chain holdings require additional steps before bridging: DeFi positions on protocols such as Tempest and Ambient must be unwound first, and wrapped tokens or protocol-specific claims may need separate actions.

The team published a list of assets that remained on Swellchain, including weETH, KING, wstETH, USDe, sUSDe, ENA, ezETH, rsETH, EUL, XVELO, oUSDT and USDT0, and cautioned the list was not exhaustive. It advised users to verify holdings directly on a block explorer because some portfolio trackers had stopped showing Swellchain balances.

The project noted that while contracts would continue to exist after the frontend was retired, the normal, supported recovery path would disappear and recovery would become more technical. The company attributed the shutdown to slower-than-expected restaking growth, improvements on Ethereum’s base layer that lowered fees, and the need to reallocate engineering and business development resources to Faro.

As of June 23 there was no public notice extending the withdrawal deadline or reversing the warning that funds left on Swellchain after the cutoff could become unrecoverable.
