Wu said that Tether announced an update to its plan to terminate support for five legacy blockchains (Omni, Bitcoin Cash SLP, Kusama, EOS, Algorand). Although the issuance and redemption of USDT on the above networks will cease starting September 1, 2025, Tether has decided not to freeze the smart contracts on these networks in response to community feedback. Users can still transfer old chain USDT between wallets, but official support will no longer be provided.
