DyorSwap: The previously identified "GIWA mainnet" was actually a fake chain set up by scammers, and affected users will be compensated through treasury funds
Odaily report: DyorSwap has officially announced that the so-called "GIWA mainnet" previously identified by the team was actually a fake chain set up by scammers.

The team also identified several suspicious messages and individuals in the related community who may be connected to this incident. The announcement stated that significant losses have already been caused through this fraudulent cross-chain bridge.DyorSwap stated that it is immediately taking three measures: first, contacting a professional security team to conduct further on-chain tracing and investigate the addresses, transactions, and fund flows involved; second, preserving all relevant evidence, including chat records, RPC information, cross-chain bridge addresses, and on-chain transactions; third, preparing to use treasury funds to compensate affected users, with eligibility criteria, loss verification procedures, compensation scope, and a detailed plan to be announced after the investigation and verification process is completed.DyorSwap emphasized that until further notice, users should not use any unofficial GIWA mainnet RPCs, cross-chain bridges, or contracts, and should not send funds to any related addresses. The official team deeply apologizes to every user affected by this incident and stated that further updates will be released as soon as possible.
Ethereum Layer 2 infrastructure Optimism partners with Dunamu, Toss, and DB Securities to expand into the Korean market
Ethereum Layer 2 infrastructure Optimism has officially announced a tripartite strategic collaboration, joining forces with Upbit operator Dunamu, fintech platform Toss, and DB Securities to comprehensively expand into the Korean market. On the cooperation front with Dunamu, both parties will upgrade the GIWA public chain based on the OP Stack and promote its global development.

This will facilitate the phased on-chain commercialization of local physical assets, with the entire cooperation framework tailored to align with Korea's financial regulatory framework.
DYORSWAP Responds to Fake GIWA Incident: Approximately 766 ETH Transferred Out, Over 200 ETH Already Compensated
DYORSWAP has released an "Official Statement Regarding the Fake GIWA Mainnet 9134 Incident," stating that the incident was not a DYOR contract vulnerability, but rather was caused by a fraudulent network impersonating GIWA Chain 9134. This network had a bridge and batcher similar to OP Stack, deployed on September 27, 2026, at 02:10:59 (UTC+8). Approximately 8.5 hours before deployment, the address received about 0.045 ETH from a ChangeHero-related address. Data shows that a total of 1,335 addresses bridged approximately 767.65 ETH to it, of which about 766.25 ETH was ultimately transferred out from the cross-chain bridge.DYORSWAP stated that it has already used its own funds to compensate affected users with over 200 ETH. Additionally, the team is still tracking the cross-chain bridge deployer, the source of funds, early test wallets, and the subsequent flow of the transferred funds.
