Tether expands native USDT support on Bitcoin via RGB

Tether, the issuer of the world’s largest stablecoin USDT, has expanded native support of the US dollar-pegged asset in the Bitcoin ecosystem via the RGB protocol.

In an announcement on August 28, 2025, Tether said it is looking to unlock value on Bitcoin, with plans to launch USDT on RGB coming amid notable expansion in the stablecoin market as major players take advantage of a shift in regulatory approach.

Why is USDT key to Bitcoin?

Per details on DeFiLlama, Bitcoin is the third-largest chain in terms of total value locked, behind Ethereum and Solana.

A lot of this has come amid a spike in decentralized finance activity on Bitcoin, a market analysts say could explode in coming years.

Stablecoins are at the heart of the growth, with segments such as real-world assets taking an upward trajectory.

Tether’s USDT currently accounts for over $167 billion market in the $292 billion stablecoin sector.

Earlier this month, Tether publshd its Q2, 2025 report that highlighted a $20 billion USDT increase in supply to the date. The company also became one of the largest holders of US debt with $127 billion.

Growth potential has seen Tether tap former White House Crypto Council executive director Bo Hines as its strategic advisor for digital assets and US strategy. 

Meanwhile, RGB has recently attracted notable attention as a Bitcoin ecosystem project following a successful mainnet release.

The protocol allows users to access private, scalable, and user-controlled asset issuance, with this key to the launch of native stablecoin support on Bitcoin. 

RGB therefore makes it possible for users to directly transact USDT on Bitcoin, potentially bringing the top digital asset to billions of people.

Combining Bitcoin’s security and Tether’s stability is a crucial milestone in the quest to make native stablecoin use on Bitcoin a reality, Tether noted.

Bitcoin currently trades near $113,300 as bulls attempt to rebound to its all-time high above $124k.
