Tether Ends Support for USDT on Five Blockchains: What Users Need to Know

Tether Winds Down Legacy Chain Support

Tether, the issuer behind the world’s largest stablecoin USDT, has announced it will officially discontinue support on five blockchains by September 1, 2025. This marks a significant operational shift as the company looks to optimize resources and double down on more active, scalable networks.

The decision follows a broader industry trend of consolidating stablecoin issuance around high-volume, developer-rich chains.

Which Blockchains Are Affected?

The five networks losing USDT support are:

• Omni Layer
• Bitcoin Cash SLP (Simple Ledger Protocol)
• Kusama
• EOS
• Algorand

Tether referred to these as “legacy” blockchains where USDT circulation has significantly dropped in recent years. Minting had already been paused on these chains in previous phases—this announcement finalizes the transition.

Freeze Date and Timeline

• September 1, 2025: All redemptions, transfers, and minting of USDT will cease. Remaining tokens will be frozen indefinitely.
• Prior Steps:
• Minting was halted on Omni, SLP, and Kusama in August 2023.
• Minting was halted on EOS and Algorand in June 2024.
  This new update completes the full discontinuation process.

Why Is Tether Making This Move?

Tether cited three key reasons for the decision:

1. Declining Usage

USDT volumes have drastically dropped on these chains, with minimal user or developer activity to justify continued support.

2. Strategic Optimization

The team plans to reallocate resources to faster, more scalable chains with robust DeFi ecosystems—such as Ethereum, Tron, Solana, and Lightning Network.

3. Future-Focused Roadmap

With Layer 2s gaining traction and DeFi-native chains driving utility, Tether aims to enhance interoperability while reducing overhead on underutilized networks.

What Users Need to Do

If you’re holding USDT on any of the affected chains, Tether strongly advises action before September 1:

✔ Redeem via Tether

Use Tether’s platform to redeem tokens or request a re-issuance on another chain.

✔ Use Exchanges or Bridges

If you’re not a Tether customer, migrate tokens through centralized exchanges or blockchain bridges that support chain-swapping.

✔ Check Supported Chains

USDT will remain active on over a dozen other chains—visit Tether.io to view the current list.

Failing to act before the freeze will leave your USDT locked and unusable.

Industry Context

This isn’t the first time Tether has trimmed support. Previous cuts included networks with low liquidity or poor developer momentum. The company continues to invest in newer blockchain integrations and aims to future-proof USDT’s role in decentralized finance.

Did You Know?

Did you know? The Omni Layer—now being retired—was the original home of USDT when it launched in 2014. The move away from Omni closes a historic chapter in stablecoin history.
