Stablecoin issuer Tether has invested in Utexo, a startup building infrastructure that enables native USDT settlement directly on the Bitcoin network, signaling a strategic push to expand the world’s largest stablecoin onto Bitcoin’s base layer. 

The investment was part of a $7.5 million seed funding round co-led by Tether, alongside investors including Big Brain Holdings, Portal Ventures, and several venture capital firms focused on digital assets. 

Bringing Stablecoin Payments Back to Bitcoin

Utexo is developing technology designed to allow USDT transactions to settle natively on Bitcoin, including through the Lightning Network, which enables faster and cheaper transactions compared with Bitcoin’s base layer. 

The system combines several technologies—including Bitcoin, Lightning, and the RGB protocol—to create a payment stack that allows stablecoin transactions to be processed instantly with predictable fees. 

Through a single API integration, payment companies and wallets could route USDT transactions across Bitcoin infrastructure without changing their existing custody or compliance systems. 

The goal is to make stablecoin transfers on Bitcoin practical for real-world financial applications.

Fixed Fees and Faster Settlement

According to Utexo, the platform is designed to solve several challenges that have historically limited stablecoin usage on Bitcoin, including unpredictable transaction fees and slow settlement speeds.

The infrastructure promises:

  • Fixed and predictable transaction costs

  • Atomic settlement, meaning transactions complete fully or not at all

  • Settlement speeds under one second via Lightning infrastructure

  • Private execution, with encrypted transaction data written to the blockchain 

Fees for transactions are expected to be paid directly in USDT, creating a stable fee model independent of Bitcoin’s block-space demand. 

Strengthening Bitcoin as a Global Settlement Layer

The investment reflects Tether’s broader strategy to strengthen Bitcoin’s role in global financial infrastructure.

While USDT currently operates on multiple blockchains, including Ethereum, Tron, and Solana, bringing stablecoin settlement back to Bitcoin could combine Bitcoin’s security with dollar-denominated liquidity. 

With USDT already the largest stablecoin in the crypto market, even partial migration of payment volume onto Bitcoin could significantly expand the network’s role in global digital payments.
