Synthetix announced that its perpetual contract market on Arbitrarum has entered a closed only mode, and users are unable to open new positions or increase existing positions. This move is part of Synthetix's strategic adjustment aimed at integrating operations and focusing on Coinbase's Base network. With the gradual discontinuation of USDx on Arbitrarum, Synthetix Treasury has started repurchasing USDx from the market and providing stability and liquidity support. Synthetix has requested liquidity providers on the Arbitrarum platform to migrate to Base and will provide additional incentives at Base to facilitate the migration. The existing positions can still be closed or reduced during the retirement period of Arbitrarum. In addition, Synthetix also plans to integrate ecological projects such as Kwenta and TLX into a unified native trading platform.
