PANews reported on June 6 that according to official news, Synthetix announced a full return to the Ethereum mainnet and launched a perpetual contract exchange. This move is aimed at addressing the problem of Layer2 liquidity fragmentation - the current mainnet carries more than 50% of the DeFi lock-up volume, which is more suitable for institutional-level product needs. The new platform adopts an off-chain order matching + on-chain batch settlement architecture: user funds are hosted on the mainnet, transactions are processed by the off-chain engine, and finally settled on the mainnet to avoid L2 risks; the order book model improves liquidity and trading experience, taking into account performance and decentralization. In addition, the SNX pledge mechanism will be simplified, and users can earn income by staking without complicated operations; the sUSD stablecoin function will be restarted, and the issuance and destruction will be dynamically managed by the Ministry of Finance, becoming the core collateral asset of the exchange. The first phase of the incentive plan will be launched this month, opening sUSD and sUSDe pre-deposited contracts. Early participants can receive 500 invitation codes for testnet access and trading competitions, and the prize pool includes SNX and other rewards. This return will fill the gap in the mainnet high-performance perpetual contract exchange and strengthen Ethereum's position as a financial hub.
