Stablecoin issuer Tether says it is expanding its partnership with Opera, creator of a self-custodial wallet built on Celo.
According to a blog post, Opera’s MiniPay wallet will now support USD₮ and XAUt0 (Tether Gold).
Tether states that the MiniPay wallet has become one of the world’s largest self-custodial stablecoin with over 12.6 million activated wallets, 350 million transactions, and 3.64 million estimated on-chain users on Celo.
In Q4 2025, MiniPay reportedly saw 50% growth in on-chain users, thus highlighting USD₮ adoption across Africa, Latin America, and Southeast Asia.
As of December, 2025, MiniPay is said to have 7 million phone-verified USD₮ wallets.
Paolo Ardoino, CEO of Tether, says by working with Opera/Minipay, they are supporting financial inclusion.
“Millions of users are now holding, sending, and saving in digital dollars seamlessly, often for the first time. MiniPay brings stable, on-chain money to the people who need it most,” said Jørgen Arnesen, EVP Mobile at Opera.
