Da Nang has just opened a sandbox for a very "real" use-case: Who will need to convert USDT to VND? The problem isn't just for traders. ➢ The solution mentioned: MIMO (Dragon Lab). Key point: this is a sandbox approved by the Da Nang City People's Committee, with a clear scope and duration (not "anyone can use it everywhere"). The testing period reported in the press is: December 2025 to December 2028. ✓ MIMO operates on a Non-Custodial mechanism: simply put, the platform Vai as a technical intermediary/coordinator, while users still transact using their own wallets and bank accounts according to a predefined transaction flow. ➢ Join early: mimo.dragonlab.com.vn/download...… Sandbox is being implemented at 3 locations in Da Nang: • Software Park No. 1 (02 Quang Trung) • Software Park No. 2 (Nhu Nguyet Street) • Innovation and Startup Support Center (58 Nguyen Chi Thanh) Use flow (summarized according to the publicly available description): ☐ User eKYC → Link bank + wallet ☐ VND→ USDT: Transfer VND according to instructions → USDT to user's wallet ☐ USDT → VND: Send USDT from user's wallet → VND to user's bank account ✦ Risk note: The system has layers of control such as eKYC/AML, logging & reporting according to sandbox regulations; wallets are checked using on-chain analytics tools to reduce the risk of money laundering/fraud. Regarding exchange rates: the project describes a mechanism for referencing prices from multiple major exchanges and a "temporarily fixed" window of 15 minutes for each conversion; strong fluctuations may be temporarily suspended to protect users. Who will need it? The problem isn't just for traders: international visitors, experts/speakers at events, and even groups of students/lecturers wanting to experience fintech in a supervised environment are also mentioned as target groups. ➯ Why is this noteworthy (from a market structure perspective)? This is a test run to connect digital assets with the real economy through risk management/compliance strategies — something the Vietnamese market has long lacked. But remember: sandbox = limited scope, not a "universal standard" for the whole country. We will be monitoring further: fees, transaction limits, processing SLAs, incident playbook, and real-world user experience in the sandbox.
