Scammers stole approximately $2 million in ETH through a fake bridge that simulated being the mainnet of the blockchain network GIWA, deceiving decentralized exchange DYORSWAP, which initially mistook the fraudulent infrastructure for the project’s actual launch.
According to a reconstruction published by DYORSWAP, the fraudulent bridge received around 767.65 ETH from 1,335 different addresses, of which the attackers drained 766.25 ETH before the fraud was detected.

GIWA, the L2 network on Ethereum developed by Dunamu, operator of South Korean exchange Upbit, clarified that its mainnet had not been launched and warned that the connection data circulating online was fake.
“We do not have our mainnet operational at this time,” the project wrote in an official statement. Dunamu had deployed the GIWA Sepolia testnet in September 2025 using Optimism‘s OP Stack, and in April signed an agreement alongside Hana Financial and POSCO International to test a cross-border remittance system based on GIWA Chain with real commercial transactions.
DYORSWAP indicated that its contracts were not compromised, that it continues tracking the bridge deployer and the recipient addresses of the funds, and that it has already used its own capital to compensate affected users with more than 200 ETH.
