Tether halts USDT freeze on legacy chains, adopts ‘unsupported’ status

Tether will no longer freeze USDT on Omni, BCH SLP, Kusama, EOS, Algorand, and other legacy chains. The assets, however, become “unsupported,” entering a financial limbo without official issuance or redemptions.

On August 29, USDT issuer Tether announced a significant revision to its transition plan for legacy blockchains. Originally, the company had planned to freeze USDT tokens and halt redemptions on networks including Omni Layer, Bitcoin Cash SLP, Kusama, EOS, and Algorand starting September 1, 2025.

Following extensive feedback from user communities, Tether opted to abandon the freeze while still discontinuing official issuance and redemption. This leaves tokens on these networks in an “unsupported” state, where transfers between wallets remain possible but the assets no longer carry the same backing or operational support as USDT on active chains.

A strategic pivot, not a retreat

Tether’s decision to walk back the freeze suggests that pushback from developers and users on networks like EOS and Algorand presented a reputational risk that outweighed the technical simplicity of a clean break.

The revised approach, which Tether states “aligns with its broader strategy,” is a pragmatic compromise. It allows the firm to shed the operational burden of supporting low-traffic chains while avoiding the public relations nightmare of effectively destroying user assets.

However, while the issuer pares down its support on one front, it is aggressively expanding on another. Just one day prior to this announcement, Tether revealed plans to launch a native USDT on Bitcoin via the RGB protocol.

The move can be seen as Tether’s strategic bet on Bitcoin’s foundational security. Unlike wrapped assets on bridges, which introduce counterparty risk, RGB leverages Bitcoin’s own scripting and client-side validation to make USDT an intrinsic part of the Bitcoin ecosystem.

Tether already distributes the stablecoin across Ethereum and Tron, each with over $80 billion in circulation, and on smaller platforms like Solana, Avalanche, Celo, and Cosmos.
