The stablecoin public chain sector has been getting interesting lately. There is a project that offers zero-fee USDT transfers, which is indeed convenient for small transactions and cross-border remittances—don't underestimate those small fees; they add up to costs over time.

Its architectural design is worth noting: built on a Bitcoin sidechain, native BTC can be directly integrated into DeFi for profit without wrapping or custodianship. From a security perspective, this approach is very clean. The native tokens have two uses: one is for ecosystem governance voting rights, and the other is staking mining to earn dual rewards. Early participants have indeed profited.

What’s even more interesting is the ecosystem's completeness. On-chain USDT liquidity continues to grow, and off-chain, digital banking services and Visa physical card support are integrated. This allows users to perform DeFi operations on-chain and seamlessly switch to traditional payment scenarios, greatly reducing friction. For ordinary users, this is a concrete realization of "compliant crypto finance"—no longer just theoretical, but truly usable.
