Key Takeaways
- After Sept 1, 2025, Omni, SLP, Algorand, Kusama, and EOS will no longer support USDT redemptions or transfers.
- Use Tether’s platform or supported exchanges to move your USDT to active blockchains like Ethereum or Tron.
- Holding funds on low-usage blockchains can result in frozen or unsupported assets in the future.
- Developers and users must adapt quickly to infrastructure changes to avoid disruption or losses.
Tether has announced a major structural shift effective September 1, 2025: it will stop supporting USDT, including minting, redemptions, and transfers, on five legacy blockchains: Omni, Bitcoin Cash SLP, Algorand, Kusama, and EOS. Any USDT left on these networks after the deadline will be frozen indefinitely, so this is a true “use-it-or-lose-it” scenario.
This means users holding USDT on these blockchains must act now to avoid losing access to their funds.
Why the Sudden Shift? Tether Explains
Tether reviewed on-chain data and found that USDT volume on these blockchains has plummeted. For example:
1. Sharp Decline in Usage
- Omni has dwindled from billions issued to just $83 million USDT in circulation .
- Bitcoin Cash SLP remains under $1 million USDT.
- Kusama hosts about $240,000; EOS just $4.2 million; Algorand holds ~ $842,000 USDT.

2. Shift to High-Activity Networks
Tether CEO Paolo Ardoino says the move helps reallocate resources to networks with better scalability, developer engagement, and community adoption, such as Ethereum, Tron, Solana, and emerging Layer-2s like Lightning Network.
3. Phased Strategy in Motion
The withdrawal didn’t happen overnight, Tether started halting new mints of USDT on Omni, SLP, Kusama back in 2023, and on EOS and Algorand in mid‑2024. Now they’re completing the phase-out by freezing remaining tokens.
What Happens on September 1, 2025?
After this date:
- No new USDT will be minted or redeemed on the five affected chains.
- Remaining tokens will be frozen and unusable for transfers.
- Exchanges and wallets may stop supporting these USDT versions, making them invisible to users.
What Should You Do If You Hold USDT on These Blockchains?
Step 1: Check Where Your USDT Is Stored
Use blockchain explorers like:
- OmniExplorer (for Omni)
- AlgoExplorer (for Algorand)
- Kusama/Subscan, EOSX, or SLP Explorer to view balances
If your USDT is on one of the five listed blockchains, proceed to the next steps.
Step 2: Migrate or Redeem Your USDT
Two main options for your include:
- Redeem your USDT via Tether’s platform into fiat currency or request reissuance on another chain.
- Use a trusted exchange or bridge to swap USDT from the deprecated chain to a supported chain like Ethereum or Tron.
However, please note that not all wallets and exchanges may offer this service. Choose platforms with active USDT migration tools.
Step 3: Transfer to a Supported Blockchain
Move your USDT to:
- Ethereum (ERC-20)
- Tron (TRC-20)
- Solana
- Polygon
- Other layer-2 or DeFi-focused networks
This ensures your tokens remain usable and supported in the future.
Why This Matters for Crypto Users and Developers
This move highlights a key lesson: blockchains without sustained adoption and usage may be deprecated. Developers, investors, and holders must:
- Stay informed about protocol support updates.
- Avoid relying on legacy chains with low liquidity.
- Focus on interoperable, developer-active, high-volume platforms.
Other Crypto Platforms That Phased Out Token or Chain Support
Tether isn’t alone in phasing out support for underperforming chains. Here are examples of other crypto platforms phased out tokens or chain support in the past:
- Circle ended USDC support on Tron in early 2025, citing compliance and usage concerns.
- Binance and other exchanges regularly delist tokens or disable trading on low-volume chains to manage risk.
- Ethereum Classic lost backing from major DApps due to security issues, causing significant ecosystem migration.
These examples highlight a consistent pattern: platforms scale back infrastructure on inactive or risky chains to prioritize efficiency, security, and community engagement.
Conclusion
Tether’s upcoming freeze of USDT on Omni, SLP, Algorand, Kusama, and EOS marks the final stage in a phased withdrawal that began two years ago. With minimal USDT remaining on these networks and a strategic pivot towards high-performance, active blockchains, Tether is optimizing for scalability and engagement.
If you hold USDT on any of these chains, redeem or migrate before September 1, 2025, to avoid your funds being locked forever.
Staying alert to these infrastructure shifts is essential: as blockchain ecosystems evolve, only those with strong usage, liquidity, and developer activity will continue to support major assets like USDT.
FAQs
After September 1, 2025, any USDT left in those chains (Omni, SLP, Algorand, Kusama, EOS) will be permanently frozen and unusable.
No, once tokens are frozen at the protocol level, no wallet or transfer service (even decentralized ones) can move or redeem them.
Unlikely. Tether has clearly stated this move aligns with its strategy and usage data. They remain open to supporting new chains, but revival of these deprecated chains is unexpected.
Prior to the deadline, you can redeem via Tether directly for fiat or new issuance. Use a trusted exchange or bridge to swap into ETH, TRON, Solana, or other supported chains. After the cutoff, these options will be unavailable.
