Final Call for EOS USDT: What Vaulta Users Need to Know

EOS USDT Support Is Ending — Here’s What You Must Do Before September 1, 2025

On July 11, 2024, Tether announced it would sunset USDT and EUR₮ support on several blockchains—including Omni, Kusama, SLP, Algorand, and EOS, which now operates as the Vaulta Blockchain. More than a year later, the final deadline is approaching.

If you still hold USDT (tethertether) on-chain, action is required before September 1, 2025. After this date, balances will be frozen and permanently unrecoverable.

This guide explains what’s happening, what it means for Vaulta users, and what actions you can take.

⚠ TL;DR: Action Steps

• Deadline: September 1, 2025 — All EOS USDT (Vaulta) will be frozen by Tether.

• Recommended action: Move your EOS USDT to Bitfinex (official, custodial path).

• Alternative now: Swap to A or USN on-chain via DefiBox (note: these are not stablecoin replacements)

Alternatives coming soon: 1DEX Recycle Program (1:1 swap to exSat USDT). Future bridge functionality will allow exSat USDT to move back into Vaulta Native.

Understanding EOS USDT Today

Tether’s announcement refers to “EOS” as the network it is winding down support for. That network now operates as the Vaulta Blockchain following its rebrand and strategic repositioning.

If you hold “EOS USDT” on-chain, it’s registered under the tethertether contract on Vaulta. If your USDT is held on a centralized exchange such as Bitfinex, KuCoin, or Binance, the tokens are custodial and not tied to the on-chain contract—so no action is required. Tether’s shutdown applies only to on-chain EOS USDT holders.

EOS USDT currently accounts for approximately $4 million in total circulation that is not held by Bitfinex or Tether. While the disruption is limited, the shift presents a real opportunity: Vaulta users can now access more liquid, exchange-compatible stablecoins through migration to exSat USDT.

What You Can Do Now

Option A: Move USDT (EOS) to Bitfinex

Bitfinex is the only centralized exchange confirmed to support EOS USDT deposits through the deadline.

• Once deposited, your USDT becomes a custodial balance.

• You can then withdraw it to any blockchain that supports USDT. To deposit into exSat Bank, choose any supported chain — including Ethereum (ERC-20), Tron, BNB Smart Chain, Solana, or Arbitrum. exSat Bank will automatically convert your deposit into exSat USDT (ERC-20). This ERC-20 version will be eligible for bridging into Vaulta Native once the bridge goes live in September.

• Bitfinex is the official redemption path endorsed by Tether.

Important: Users in certain jurisdictions may not be eligible to use Bitfinex. Please refer to Bitfinex's Terms of Service for a full list of prohibited countries.

Option B: Swap On-Chain Using DefiBox

DefiBox currently supports EOS USDT swaps to:

• A (Vaulta's native token)

• USN (a third-party collateral-backed stablecoin)

Note: These swaps will move you out of EOS USDT entirely. While they don't convert into a supported stablecoin like exSat USDT, they do remove exposure to frozen assets. Use only if you are moving out of USDT entirely.

If you prefer to wait for a non-custodial swap, see the upcoming 1DEX Recycle Program below.

Coming Soon: 1DEX Recycle Program

A 1:1 EOS USDT to exSat USDT swap via a simple UI on 1DEX.

• No Bitfinex account required

• Ideal for users with Vaulta Wallets

• Launch expected mid-August 2025

Recommended Stablecoin Moving Forward: exSat USDT

With the native USDT stablecoin support ending on September 1, the recommended stablecoin replacement for Vaulta is exSat USDT, which is a wrapped version of USDT on Ethereum. exSat USDT is already the main stablecoin trading pair in 1DEX. Users can currently stake exSat USDT into exSat Bank for a promotional 20% APR until September 25. No lockup period — unstake your tokens anytime!

For more information on the security of exSat USDT and instructions on how to deposit USDT into exSat Bank from any CEX or on-chain wallet, please visit the exSat Bank FAQ page.

The exSat Bank and Bridge will soon add frontend support for bridging exSat USDT (ERC-20) into Vaulta Native. This uses a new bidirectional bridge that allows wrapped stablecoins like USDT to move freely into the Vaulta ecosystem.

• Allows users who convert to exSat USDT to re-enter the Vaulta ecosystem natively.

• First-party UI expected in early September.

• No action required until after conversion is complete.

This migration unlocks greater accessibility and eliminates the limitations EOS USDT had in the past.

Additional Stablecoin Access: USD1

Vaulta and World Liberty Financial have announced a strategic partnership to advance Web3 Banking. A key focus of this collaboration is the integration of USD1, a next-generation, institutionally adopted stablecoin.

• USD1 currently has a market cap of $2.16B and ranks #43 on CoinMarketCap

• Gaining traction in real-world payments and compliant DeFi

• Will offer seamless access from within the Vaulta ecosystem

Together, Vaulta and WLFI are bridging traditional finance and Web3. USD1 is a key part of that future.

Final Checklist

• Withdraw EOS USDT to Bitfinex before Sept 1, 2025 (official and safest path)

• If not using Bitfinex, monitor 1DEX Recycle Program launch for on-chain 1:1 swap to exSat USDT (expected mid-August)

• Consider swapping EOS USDT to A or USN via DefiBox if exiting USDT entirely

• Once converted to exSat USDT, optionally stake in exSat Bank to earn 20% APR until Sept 25 (no lockup)

• After September: use exSat Bridge to bring exSat USDT into Vaulta Native for use in DeFi apps
