South Korean crypto exchange Upbit has issued an announcement warning users about recent scams impersonating the GIWA chain, an Ethereum Layer 2 network being developed by its parent company, Dunamu. Upbit stated that the GIWA chain is currently in its testnet phase, with development and preparations underway for its official mainnet launch. Any information circulating in the market regarding the GIWA chain's mainnet launch, digital asset issuance, and investment opportunities is false. Upbit urged users to verify information through official GIWA channels to avoid losses due to fraud.
