Bitcoin has long been criticized for lacking native stablecoin support. But that narrative just changed. So how do you use USD1 on the BTC network, and could this spark a new era for Bitcoin-based DeFi? Thanks to WLFI and Nubit, USD1 is bringing real-world use cases to Bitcoin's mainnet.
What Is USD1 and Why Is It Important?
USD1 is a dollar-pegged stablecoin managed by BitGo and issued by World Liberty Financial. It's fully backed by US Treasuries and now live on the Bitcoin mainnet via the Thunderbolt Network—making it the first major stablecoin to function natively on Bitcoin.
How Does USD1 Work on the Bitcoin Thunderbolt Network?
Thunderbolt is a soft-forked Bitcoin layer that uses innovations like UTXO bundling and OP_CAT instructions. It enables smart contract functionality and asset issuance directly on Bitcoin. USD1 can be transferred with ultra-low fees and near-instant finality.
What Can You Do With USD1 Right Now?
Send and receive payments natively on Bitcoin.
Purchase nodes on Thunderbolt.
Interact with emerging Bitcoin DeFi protocols (planned).
Early adopters already report a 1.000–2.000x performance increase over legacy BTC transactions.
What's the Broader Vision for USD1?
WLFI and Nubit aim for USD1 to dominate BTC-native stablecoin usage, with projections stating that over 90% of USD1's volume will settle on Thunderbolt. The initiative ties into broader efforts to expand Bitcoin's role in decentralized finance.
Conclusion:
Using USD1 on the BTC network is no longer theoretical—it's real, live, and rapidly scaling. As stablecoins go native on Bitcoin, it could redefine the chain's utility far beyond store-of-value. This isn't just a tech upgrade—it's a use-case revolution.
