WLFI advisors recently revealed that the stablecoin USD1 has officially integrated with the Bitcoin Thunderbolt network launched by Nubit, becoming the only stablecoin currently active on the Bitcoin mainnet. Previously, Tether had abandoned the Omni version of USDT, and the launch of USD1 not only fills the gap but also opens up a high-speed channel for stablecoins on the BTC mainnet. This step is significant. Users can now directly transfer and receive USD1 on the Bitcoin mainnet, and even use it to pay for node service fees on the Lightning Network. The deep cooperation between WLFI and Nubit is substantially expanding Bitcoin's application capabilities in stablecoins and payment scenarios. More importantly, USD1 is expected to capture over 90% of the stablecoin circulation on the Lightning Network, forming a de facto monopoly. Don't forget, as early as April, the Bitcoin Lightning Network introduced UTXO Bundling and OP_CAT instructions through a soft fork, raising on-chain performance to 1000–2000 times that of the original chain. The combination of stablecoins and a high-performance Bitcoin network is redefining BTC's financial imagination. It's time to reassess Bitcoin's potential in the DeFi and payment markets.
