Where studios get stuck.
LIFF SDK is LINE-specific. Login, share, and pay flows do not transfer from Telegram or Meta. KYC and age rating differ per country. DOSI economy integration is a separate engineering track entirely.
How Hangar handles it.
Hangar exposes LINE LIFF login, LINE Pay, and the JP/TW-specific KYC and age-rating packaging as a single adapter step. DOSI integration is a Hangar module rather than a custom build.
Common questions about LINE.
What is the difference between LINE MINI App and DOSI?
LINE MINI App is the general LINE-app embedded WebView program, used for utility apps, commerce, and games. DOSI is LINE NEXT's blockchain-anchored MiniApp game initiative, with chain payments, NFT economies, and a curated launch slate. A studio can ship to one or both.
How long does LINE review take?
Typical LINE MINI App review takes 1 to 2 weeks for first submission. DOSI program onboarding adds BD review time on top. Hangar packages the review submission per platform to avoid round-trips.
Do I need a Japanese entity to ship on LINE?
Not always for MINI App, but a JP entity simplifies LINE Pay payouts and tax. DOSI partners typically work through LINE NEXT BD which handles the JP-side payment relationship for non-JP studios.
