The system is built on peer-to-peer Holepunch protocols, eliminating the need for centralised services and third-party dependencies.

The software is distributed under the open Apache 2.0 license, ensuring users the freedom to use, modify, and distribute the code for both commercial and non-commercial purposes. 

“For a long time, the mining industry was limited to closed systems and proprietary tools. MiningOS changes this […]. No black boxes. No lock-ins. No limitations,” noted the issuer of USDT.

Tether first announced plans to create open-source software for bitcoin mining in June 2023, emphasising the importance of allowing new participants to “enter the game and compete” without reliance on costly third-party vendors.

Tether and Opera

The issuer of USDT and browser developer Opera have partnered to enhance financial accessibility in emerging markets. As part of the collaboration, Tether has integrated its stablecoin and tokenised gold XAUT into the MiniPay self-custodial wallet ecosystem. 

The initiative aims to provide users in regions with unstable national currencies (Africa, Latin America, and Southeast Asia) with easy access to dollar-denominated digital assets for daily transactions, transfers, and savings.

“Tether’s mission has always been to provide a simple and reliable means of preserving value for those who need it most,” commented Ardoino.

MiniPay operates in 60 countries and has 12.6 million active wallets. In the fourth quarter, the service’s user base grew by 50%, primarily in emerging markets. 

At the end of 2025, Tether’s net profit amounted to $10 billion.
