(UPbit Terms of Use Article 17, Paragraph 8) ### ※ Additional Digital Asset \~\~API3 (API3)\~\~ > API3 is a project that builds decentralized APIs (Application Programming Interfaces) for Web 3.0. Decentralized applications (dApps) should be able to access Web APIs that provide services interacting with the real world. However, most APIs are not compatible with dApps via on-chain integration. While existing third-party mediator interface solutions are centralized, insecure, and costly, API3 aims to replace them through a decentralized platform. API3 seeks to advance the concept of APIs so that the strict decentralization requirements of Web 3.0 can be met without third-party intermediaries. > Website : [API3 Official Website](https://api3.org/) > X (formerly Twitter) : [API3 Official X](https://x.com/Api3DAO) > Whitepaper : [API3 Official Whitepaper](https://drive.google.com/file/d/1b8QsGPCJJC1pQOcg83-knD1IAOIgCtZZ/view) ✽ If this digital asset does not appear on PC, please refresh (F5) and check again. ✽ If the digital asset does not appear in the Upbit App, please click on More > Display Settings > Retrieve Coin Info Again and check.

Investment Risk Notice

• Investment in digital assets is exposed to drastic price fluctuations due to speculative demand and changes in domestic and international regulatory environments. Responsibility for investment decisions lies with the investor, and any potential losses are also borne solely by the investor. Please carefully refer to the project website and official documents to fully understand the characteristics of digital assets, and trade prudently.

• Due to the characteristics of digital asset trading, price differences between domestic and international exchanges may persist. Be sure to check price gaps between global exchanges before investing in digital assets.

• Upbit takes various measures, such as setting a minimum order amount, to ensure a stable trading environment. However, depending on the overheated market conditions, some users may see order stabilization messages. This is an unavoidable measure to process earlier orders and maintain stable service, so please take note.

※ Virtual assets are high-risk products and may cause partial or total loss of investment funds.
