Korea is building onchain, and they’re choosing Optimism. @GIWA_by_Upbit, built by Korea’s largest exchange, has 100M testnet transactions and counting. @toss__official, Korea’s super app used by 30M+, is exploring a won-backed stablecoin. DB Securities, a securities and underwriting firm, is tokenizing smart-farming and livestock assets as RWAs. KB Securities, one of Korea's leading securities firms, signed an MOU to bring tokenized funds to Korean institutional investors. Exchange. Super app. Securities Firms. All on one stack.
