Stablecoins go mainstream with LINE NEXT: Unifi builds cross-chain deposits on Rhino.fi

Unifi, the stablecoin wallet from LINE NEXT, is bringing digital dollars to a genuinely mainstream audience, and it is building its cross-chain deposits on Rhino.fi.

LINE NEXT is the Web3 venture of LY Corporation (LINE Yahoo) focused on building the global Web3 ecosystem. Unifi, its stablecoin wallet, launched globally in 2026 and is accessible via the Unifi website and LINE App with no separate app installation required. Users can hold USDT, earn interest in a few taps. This is stablecoins reaching people who have never touched crypto before.

In Asia, the USDT people already hold sits overwhelmingly on Tron, alongside other chains. Asking a mainstream user to bridge and route it themselves is exactly where a first deposit stalls and a new user is lost.

Rhino.fi is built for that moment. Not just the mechanics of moving money between chains, but the outcome the product needs: a balance that is live and usable the instant it lands. Unifi integrated Rhino.fi to power its first cross-chain deposit feature, giving users deposit addresses that turns USDT from any chain into a usable Unifi balance in ~20 seconds.

How it works

Each Unifi user is issued one Smart Deposit Address across EVM chains, with dedicated support for Tron and beyond.  Rhino.fi detects the inbound deposit, runs KYT screening, and uses its own cross-chain liquidity system to settle the funds onto Kaia, the network Unifi is built on, where they land as a usable Unifi balance in ~20 seconds, with no bridging, wrapping or manual steps for the user. The entire flow sits behind Unifi's interface, so the complexity stays invisible to the person using the service.

Three reasons Unifi built on Rhino.fi

One address across EVM chains, with dedicated support for Tron and beyond.  A Unifi user gets addresses that accept USDT from wherever they already hold it. In Asia that means Tron above all, plus the other major chains and CEXs, with no bridging or routing for the user to think about.

Balances that arrive ready to use. A deposit lands as a usable Unifi balance in under 20 seconds, ready to earn interest, spend or send. The user funds once and is immediately active.

An enterprise partner to operate and scale with. Unifi did not just need a bridge, it needed infrastructure it could run a consumer product on. Rhino.fi handles routing, liquidity and KYT screening on every deposit, settles Tron deposits in under 20 seconds on enterprise-grade infrastructure, and works alongside the Unifi team on the operational layer consumer apps require: reliability and uptime guarantees, refund handling, bespoke fee configuration and more. As Unifi scales, the model scales with it.

Unifi is one of the clearest signs yet of where stablecoins are heading: out of crypto-native service and into the everyday platforms people already use. When that happens, the deposit becomes the front door to the entire experience. Powering it for a wallet bringing stablecoins to mainstream users is exactly where Rhino.fi operates best.

"Most stablecoin products today are still built for people who already understand crypto. Unifi is attempting something far harder and more valuable: putting stablecoins in front of LINE NEXT's mainstream audience, where the deposit has to feel invisible or the user is gone. Bringing USDT in from Tron in seconds is the start, but what made Rhino the right foundation was our ability to operate reliably at consumer scale, alongside the team on operational overhead like refunds and bespoke and sponsored fees. This is what powering mainstream stablecoin adoption actually looks like."
