Binance has announced the upcoming delisting of four trading pairs: ACT/USDT, FIO/BTC, TNSR/FDUSD, and TST/FDUSD. The changes will take effect on July 4, 2025, as part of the exchange’s regular market optimization process. While the tokens themselves are not being removed from the platform, the removal of specific trading pairs may impact how users access and trade these assets—especially those relying on fiat-linked or experimental stablecoin markets.
This move reflects Binance’s ongoing efforts to streamline its offerings, focusing on high-liquidity pairs and widely adopted stablecoins. Let’s break down each delisting, explore the implications for investors and traders, and understand what this means for broader trends in AI-driven protocols and Solana-based ecosystems.
Why Binance Delists Trading Pairs
Crypto exchanges like Binance routinely review their listed trading pairs to ensure optimal performance, security, and user experience. Delisting doesn’t always signal trouble—it often indicates a shift in market demand or strategic alignment.
Common reasons for delisting include:
- Low trading volume
- Poor liquidity
- Shifts in stablecoin adoption
- End of experimental projects
In this case, Binance is not removing any underlying tokens but is instead retiring specific quote currencies (like FDUSD or BTC) from certain pairs. This helps consolidate trading activity into more efficient markets and improves price discovery across the platform.

ACT/USDT Delisting: Implications for AI and Decentralized Innovation
The delisting of the ACT/USDT pair has drawn particular attention due to its association with Act I: The AI Prophecy Project. ACT is the native token of a decentralized protocol exploring the intersection of artificial intelligence and blockchain technology.
Unlike traditional AI chatbots designed for corporate safety and compliance, Act I encourages open experimentation, memetic collaboration, and self-organizing AI collectives. It appeals to developers and futurists interested in decentralized intelligence models that evolve through community input.
While the delisting might raise concerns, it's important to note that ACT will remain tradable against other major pairs such as ACT/BTC and ACT/BNB. The removal of ACT/USDT suggests a rebalancing rather than rejection—possibly due to lower volume compared to other pairs.
Still, this shift could temporarily affect short-term traders using stablecoins for quick entries and exits. Long-term holders and participants in the AI protocol ecosystem should monitor where ACT gains traction next.
FIO/BTC Removal: Usability vs. Market Realities
The FIO Protocol aims to simplify cryptocurrency transactions by replacing complex wallet addresses with human-readable handles—similar to email addresses (e.g., user@wallet). This UX-focused innovation has potential, especially for onboarding new users.
However, despite its utility, the FIO/BTC trading pair hasn’t maintained sufficient volume on Binance. BTC-denominated pairs typically require strong, sustained trading interest to justify their place on large exchanges. With limited activity, Binance’s decision aligns with standard market hygiene practices.
FIO remains available against other quote currencies like USDT and BNB. But the BTC pair removal may reduce visibility among Bitcoin-centric traders who prefer direct BTC trades over stablecoin intermediaries.
This highlights a recurring challenge in crypto: even projects with strong technical foundations can struggle if trading liquidity doesn’t follow.
TNSR/FDUSD: Solana’s NFT Infrastructure Faces Stablecoin Shift
TNSR, the governance token for Tensor—a leading NFT marketplace on Solana—is seeing its TNSR/FDUSD pair delisted. This change reflects a broader trend: the consolidation around dominant stablecoins like USDT and USDC on Solana.
FDUSD (First Digital USD), while functional, hasn’t achieved widespread adoption in Solana’s DeFi and NFT ecosystems. Most liquidity pools, lending protocols, and trading platforms prioritize USDT and USDC due to their deeper reserves and cross-platform compatibility.
By removing TNSR/FDUSD, Binance is effectively encouraging traders to use more liquid stablecoin pairs. This supports better pricing accuracy and tighter spreads—benefiting both retail and institutional participants.
For Solana investors, this underscores the importance of stablecoin choice when building or trading within DeFi applications. Projects integrating with top-tier stablecoins are more likely to thrive in competitive environments.

TST/FDUSD: End of an Experimental Phase
The TST/FDUSD pair was part of Binance’s own experimental initiative linked to four.meme, a community-driven meme project. As an internal trial, it served as a sandbox for testing new listing mechanisms and user engagement models.
Now that the experiment has concluded, the natural next step is decommissioning the associated trading pair. This is standard practice for time-bound or proof-of-concept tokens.
Importantly, this delisting does not reflect broader issues with meme coins or community tokens—it simply marks the end of a limited-run program. Future experiments may introduce similar temporary pairs, giving users early access to emerging trends.
What Traders Should Do Before July 4
Binance has reminded users to take action before the delisting date:
- Cancel any active orders in the affected markets.
- Disable automated trading bots linked to these pairs.
- Consider switching to alternative trading pairs (e.g., trade ACT via ACT/BTC or TNSR via TNSR/USDT).
Failure to act could result in unexecuted trades or unexpected positions. However, there’s no need to panic—funds remain safe, and most tokens retain multiple trading options on Binance.

Frequently Asked Questions (FAQ)
Why is Binance delisting these trading pairs?
Binance regularly reviews its trading pairs to maintain high liquidity and user experience. These delistings are due to low trading volume and strategic alignment with more widely used stablecoins like USDT and USDC—not because of any security or project failure.
Does this mean ACT, FIO, TNSR, or TST are being removed from Binance?
No. Only the specific trading pairs (ACT/USDT, FIO/BTC, TNSR/FDUSD, TST/FDUSD) are being delisted. The tokens themselves will still be available for trading against other quote currencies like BTC, BNB, or USDT.
Will I lose my tokens if I don’t do anything?
No. Your tokens are safe in your account. However, any open orders in the affected markets will be canceled automatically before delisting. You should manually cancel them or transfer your holdings to active trading pairs.
What happens to FDUSD? Is it being phased out?
Not necessarily. While FDUSD isn’t gaining traction on Solana compared to USDT or USDC, it still operates on other chains. Binance’s move reflects market preference rather than a formal deprecation of FDUSD.
Can I still trade TNSR on Solana-based platforms?
Yes. Tensor (TNSR) remains a key player in Solana’s NFT ecosystem. You can trade TNSR on decentralized exchanges like Jupiter or Orca, as well as on other centralized exchanges that support Solana assets.
Was the four.meme project successful?
As an experimental initiative, four.meme provided insights into community-driven meme dynamics and short-term engagement models. Its conclusion with the TST/FDUSD delisting marks a natural endpoint—not a failure.
