Support for Omni, Bitcoin Cash SLP, Kusama, EOS, and Algorand will be suspended on September 1, 2025
July 11, 2025 – Tether, the largest company in the digital asset ecosystem, today announced an update on its plans to halt USD redemption and freeze the remaining tokens on five legacy blockchains. A blockchain that was actively developed to achieve high output.
Tether’s decision follows a comprehensive review of blockchain usage data, market demand, and feedback from community stakeholders and infrastructure partners. These networks played a fundamental role in the early growth of tethers, but the amount of US dollars circulating them has declined significantly over the past two years.
“As the digital asset ecosystem evolves, Tether is committed to adapting in line with it.” Tether CEO Paolo Aldoino said. “With these legacy chains’ sunset support, we can focus on platforms that increase scalability, developer activity and community engagement.
This decision reflects the strategic pivot of tethers to expand support for layer 2 networks (such as lightning networks) and other emerging blockchains that improve interoperability, speed, and ecosystem growth. By reallocating resources from underutilized blockchains, Tether is doubling with platforms that are suited to the global user base.
Customers who own Omni, Kusama, SLP, EOS and Algorand USD must either reimburse their holdings as soon as possible or, if necessary, request the issuance of USD on a supported blockchain in accordance with our terms of service. Non-Customer Holders may attempt to migrate USD Holdings to a blockchain supported through available service providers in accordance with the terms of these providers.
Tether continues to explore collaboration and integration with the innovative blockchain ecosystem, expanding the accessibility and utility of USD. This includes expanding support for scalable layer 2 networks and defi-native chains, where user activity and developer engagement are robust.
