According to Foresight News, the synthetic asset protocol Synthetix will stop exchanging synthetic currencies other than sUSD on Ethereum and migrate users to the V3 system. Users holding sETH, sBTC, or other spot synthetic assets other than sUSD must exchange them before April 15. After that, any remaining non-US dollar spot synthetic currencies can only be exchanged for sUSD at Chainlink prices through the L1 redemption contract. Officials said that migrating liquidity to sUSD will help introduce sUSD liquidity and increase activity on Synthetix V3.
