Tether to Cease Support for Five ‘Legacy’ Blockchains

From September 1, Tether will halt the redemption of USDT on five networks—Algorand, Bitcoin Cash SLP, EOS, Kusama, and Omni Layer—and will freeze the remaining tokens.

“Ending support for these legacy blockchains allows us to focus on platforms that offer greater scalability, developer activity, and community engagement—all key components for driving the next wave of stablecoin adoption,” stated Tether CEO Paolo Ardoino.

According to the statement, the decision was based on an analysis of protocol usage data, market demand, and feedback from infrastructure partners.

“While these networks played a foundational role in Tether’s early growth, the volume of USDT circulating on them has significantly decreased over the past two years,” the firm noted.

In August 2023, Tether ceased issuing the stablecoin in the Kusama, Bitcoin Cash, and Omni ecosystems. In June 2024, the company stopped the issuance of USDT on EOS and Algorand. Users still had the option to redeem or exchange the coins.

According to Tether’s data, about 82.9 million USDT remain in circulation on Omni, with the issuer having authorized approximately 888 million tokens. In Kusama’s so-called canary network from the Polkadot system, the corresponding figures are 239,993 and ~3.5 million USDT.

On Algorand, all 841,596 authorized tokens have entered circulation, while on Bitcoin Cash, only 986,524 coins remain from nearly 6 million theoretically available.

On EOS, the potential issuance was 82.25 million, with ~4.2 million USDT in market circulation.

Tron and Ethereum dominate, with 80.67 billion and 74.3 billion tokens issued, respectively.

Tether confirmed its commitment to expanding support for second-layer networks, including Bitcoin-based protocols like the Lightning Network, and “other new blockchains providing enhanced compatibility, speed, and ecosystem growth.”

Back in November 2024, the USDT issuer abandoned further support for the euro-pegged stablecoin EURT due to low demand and tightening regulations in the EU.
