Solana's developers forked the widely used token liquidity hub Serum, after being compromised by a hack on the bankruptcy exchange FTX on Nov. 11 that led to a series of unauthorized transactions.
According to pseudonymous developer Mango Max on Twitter, a "verified build of the same version has been made and deployed" on Nov 12. Additionaly, the upgrade authority and fee revenues "have been changed and are now managed by a multi-sig controlled by a team of trusted developers." Serum (SRM) and megaserum (MSRM) tokens, as well as fee discounts were not changed and were working as before.
