오르빗 브릿지 취약점 공격에 대한 위믹스팀의 대응 위믹스 오피셜 사이트 본문 : https://www.wemix.com/ko/communication/foundation%E2%80%99s-measures-on-orbit-bridge-exploit-7c62e981f84c 안녕하세요, 위믹스 팀입니다. 오늘 오지스의 오르빗 브릿지가 취약점 공격에 노출되어 이더리움 네트워크에 보관중인 이더리움 네이티브 자산의 상당부분이 탈취되었음이 밝혀졌습니다. 오르빗 브릿지를 이용중인 위믹스3.0과 관련해 팀은 정확한 피해 규모의 파악 및 대응 방안을 모색 중입니다. 1. WEMIX는 안전합니다. • 우선 위믹스3.0과 클레이튼간의 WEMIX ↔️ oWEMIX 컨트랙트는 큰 문제가 발생하지 않았습니다. 이에 따라, 현재 일시적으로 중단된 오르빗 브릿지가 재개되면 oWEMIX는 문제없이 WEMIX로 전환 가능합니다. • 이후에는 WEMIX의 생태계에서 큰 몫을 담당하는 Klaytn 생태계에서 도미넌스 토큰을 한번 더 변경하여 네이티브 형태로 WEMIX를 보유할 수 있도록 지원할 계획입니다. 2. WEMIX$도 안전합니다. • USDC를 준비금으로 하는 WEMIX$의 경우 브릿지가 제대로 동작하지 않을 경우 준비금의 안정성에 대한 문제가 제기됩니다. 지난 브릿지 관련 사고에서의 대응처럼 WEMIX$는 준비금의 안정성 여부를 떠나 위믹스팀이 100% 지급을 담보하며, 탄력적으로 준비금별 담보비중의 리밸런싱을 통해 대응하고 있고 그 결과 WEMIX$는 안정적으로 운용되고 있습니다. • 안전한 USDC 준비금을 위해, 발행사인 Circle의 크로스체인 메시징 프로토콜 CCTP 도입을 통해 Non-Custodial Bridging을 도입하여 이러한 브릿지들의 사고 발생 가능성에 생태계가 노출되는 것을 최소화할 계획입니다. • 현재 위믹스3.0과 이더리움간 USDC 브릿지가 존재하지 않아 외부가격 참조(oracle)에 교란이 발생하는 것을 WEMIX의 교차 가격참조로 방지하고, 생태계의 확장과 긴축에 파이프라인이 존재하지 않는 문제를 일부 해소하기 위해, 일시적으로 WCD를 준비금으로 하는 DIOS-III와 MLP-III가 제공될 예정입니다. 이에 대해서는 향후 별도의 공지를 통해 안내하도록 하겠습니다. 3. 안전한 우나 브릿지의 도입을 앞당기려 합니다. • 지난 2023년 9월 위믹스 팀이 제안한 우나기(unagi) 이니셔티브는 모든 자산은 랩토큰이 아닌 네이티브 토큰의 형태로 보관되는 것이 가장 안전하다는 기치 아래 크로스체인 메시징 방식의 비수탁 옴니체인 브릿지인 우나 브릿지의 개발을 발표하였습니다. • 이를 위해 Chainlink의 CCIP를 필두로 CP Labs의 Web2X, 그리고 Wemade의 PPP가 결합된 unagi(x)를 개발하여 2월 출시를 목표로 하고 있었으나, 이에 대한 출시에 박차를 가해 1월 중으로 선보이고 앞으로는 위믹스 생태계에 브릿지 관련 사고와 우려를 원천 차단하고자 합니다. • 또한, 우나 브릿지와 함께 WEMIX가 위믹스3.0 체인 이외에서도 네이티브 토큰 형태로 안전하게 보관되는 우나 스테이션(una station)이 제공됩니다. WEMIX는 위믹스3.0의 성장의 가치를 담는 가장 중요한 자산입니다. 자산에 대한 안정성이 담보되어야 에코시스템과 이코노미의 성장이 가능하다는 점을 최우선의 과제로 위믹스를 외부의 상황에 영향받지 않는 거대 생태계로 키워나가도록 하겠습니다. 감사합니다.

Foundation’s Measures on Orbit Bridge Exploit Official WEMIX site announcement : https://www.wemix.com/communication/foundation%E2%80%99s-measures-on-orbit-bridge-exploit-7c62e981f84c WEMIX Foundation has discovered that a significant portion of the assets held by Orbit Bridge on Ethereum has been exploited. The WEMIX team is actively investigating the extent of the exploit and diligently working towards a solution. 1. WEMIX remains secure. • The Orbit Bridge that connects WEMIX3.0 and Klaytn, facilitating the bridging of WEMIX and oWEMIX, remains unaffected. Consequently, once the bridge is operational again, oWEMIX can be successfully bridged to WEMIX. • We plan to further modify the dominance token within the Klaytn ecosystem, which plays a significant role in the WEMIX ecosystem, to enable the community to retain WEMIX in its native form. 2. WEMIX$ is also secure. • WEMIX$ relies on USDC as its reserve, and as a result, concerns about the stability of the reserves may arise if the bridge does not function properly. Similar to our response to incidents related to the bridge in the past, WEMIX$ guarantees 100% redeemability regardless of the stability of the reserves. Measures including rebalancing of the collateral ratios within the reserve have been taken, and as a result, WEMIX$ is currently operating within normal parameters and with stability. • To secure the USDC reserve, we are committed to implementing a non-custodial bridge using the CCTP(Cross-Chain Transfer Protocol) developed by Circle, the issuer of USDC. This proactive measure aims to prevent bridge exploits and minimize the vulnerability of the WEMIX ecosystem to similar incidents in the future. • Given the absence of an operational bridge between WEMIX3.0 and Ethereum supporting USDC, and to address the issue of an absent pipeline for the ecosystem’s expansion and contraction, we are temporarily incorporating WCD as a new reserve for WEMIX$ through the facilitation of DIOS-III and MLP-III. Further details regarding this will be provided in a subsequent announcement. 3. Accelerating the una bridge launch • In September of 2023, the WEMIX Foundation introduced the unagi initiative to emphasize the importance of securely retaining assets within its native chain. As part of this initiative, a non-custodial bridge utilizing cross-chain messaging protocols was proposed. • The unagi(x), featuring Chainlink’s CCIP, Web2X by CP Labs, and PPP by Wemade, has been in development with the initial launch set for February 2024. However, we are dedicated to expediting the launch of una bridge by mid-January in order to proactively address and prevent concerns related to bridges. • Also, along with una bridge, we will be releasing una station that helps users to natively retain WEMIX on other chains. WEMIX stands as the cornerstone asset, embodying the growth value of WEMIX3.0. The foremost priority is to ensure stable growth of both the ecosystem and the economy, with the overarching goal of safeguarding the stability of assets as we chart the path forward. The WEMIX team is committed to forging WEMIX into an expansive mega-ecosystem resilient to external factors. Thank you The WEMIX team
