Tether to Phase Out USDT Support on Five Blockchains by September 2025

Tether, the issuer of the world’s largest stablecoin USDT, announced plans to discontinue support for five underused blockchains: Omni Layer, Bitcoin Cash’s Simple Ledger Protocol (SLP), Kusama, EOS, and Algorand. Starting September 1, 2025, all token minting and redemptions on these networks will cease, and remaining tokens will be frozen on the same day.

The affected networks represent only a small fraction of USDT’s total circulating supply, which currently stands at approximately $156 billion. According to Tether, USDT usage on these blockchains has declined significantly over the past two years. The decision aims to streamline operations and concentrate resources on ecosystems showing higher scalability, developer activity, and user engagement.

Tether CEO Paolo Ardoino emphasized the company’s renewed focus on emerging Layer 2 solutions like the Lightning Network and other high-performance blockchains offering faster settlement and better development tools. These efforts are expected to drive the next phase of stablecoin adoption and enhance network efficiency.

Users holding USDT on the impacted chains are urged to redeem or migrate their holdings promptly. Token migrations can be done through supported blockchain bridges or exchanges that offer conversion to actively supported platforms.

Currently, over 95% of USDT is issued on Ethereum and Tron, which dominate the stablecoin’s market presence. Solana is the only other network holding more than 1% of the total supply, according to data from RWA.xyz.

This strategic move reflects Tether’s evolving priorities, reinforcing its commitment to supporting networks that align with broader market trends and long-term utility. As competition among stablecoin issuers intensifies, Tether’s pivot underscores the importance of optimizing for performance, adoption, and future growth.
