Optimism ecosystem DEX Velodrome will merge with Base ecosystem DEX Aerodrome and upgrade to Aero on October 21. According to Foresight News, the initial launch chains will be OP Mainnet and Ink, which will continue VELO issuance and voting before launch, while other chains will gradually stop token issuance and cross-chain support.

Networks that have already closed or will close Gauges include Celo, Fraxtal, Soneium, Unichain, Superseed, Metal, Mode, Swell, and Lisk. According to Foresight News, Celo, Fraxtal, Soneium, and Unichain still plan to keep trading and liquidity provision functions after Aero launches, but they will no longer support Gauges, voting, or token issuance.

The official notice said xVELO on all chains must be bridged back to OP Mainnet by October 15. Lisk assets must be withdrawn by October 31, after which they cannot be recovered. Staked LP positions should be unstaked after Gauges are disabled, except on OP Mainnet and Ink. Superseed, Metal, and Mode are no longer actively maintained, and Swell has been taken offline.
