Few assets have shaped the <a href="/ja/price" target="_blank" class="blog_inner_link">crypto market</a> as profoundly as <a href="/ja/price/tether-usdt" target="_blank" class="blog_inner_link">Tether</a> (USDT). Googling “what is Tether?” yields millions of hits because this single stablecoin provides the dollar liquidity that fuels spot trading, derivatives, DeFi, and even on-chain payments. Yet misconceptions remain about how USDT works, what backs it, and why every serious trader—from arbitrage bots on Gate.io to NFT minters on Ethereum—relies on the Tether token ecosystem every day.
##1. From Realcoin to USDT: A Short Origin Story of Tether
Tether Limited launched the prototype “Realcoin” in late 2014, re-branding to Tether months later. The premise was simple but game-changing: mint blockchain tokens pegged 1:1 to USD and redeemable for cash via the issuer. In 2015 Bitfinex integrated USDT deposits, providing traders with instant, blockchain-based dollars—no wire transfers, no weekend delays. Within three years daily USDT volume eclipsed Bitcoin’s, making Tether stablecoin the de-facto settlement rail for crypto.
##2. How Does Tether Maintain Its Peg?
- Reserve Assets – Tether Holdings holds short-term U.S. Treasuries, reverse-repos, cash, and precious-metal tokens. As of Q1 2025, 85 % of reserves are Treasury bills with average maturity < 90 days, audited by BDO Italia.  
- Creation & Redemption – Authorized customers wire USD to Tether, receive freshly minted USDT; reversed for redemptions. This arbitrage loop keeps secondary-market price near $1 because opportunities to buy cheap USDT and redeem for $1 remove downward pressure.  
- Attestation Reports – Monthly PDFs detail asset allocation and excess equity (currently $6 b), addressing the constant “is Tether fully backed?” question.
##3. Multi-Chain Expansion: More Than ERC-20
Originally an Omni-layer token on <a href="/ja/price/bitcoin-btc" target="_blank" class="blog_inner_link">Bitcoin</a>, <a href="/ja/price/tether-usdt" target="_blank" class="blog_inner_link">Tether crypto</a> now exists on 14 networks:

| Chain  | Ticker  | Typical fee  |
| ------------ | ------------ | ------------ |
| <a href="/ja/price/ethereum-eth" target="_blank" class="blog_inner_link">Ethereum</a>  |  USDT-ERC20 | $2–$8 (gas)  |
|  <a href="/ja/price/tron-trx" target="_blank" class="blog_inner_link">Tron</a> | USDT-TRC20  |  <$0.20 |
| <a href="/ja/price/solana-sol" target="_blank" class="blog_inner_link">Solana</a>  | USDT-SOL | <$0.005  |
|  Arbitrum One |  USDT-ARB | <$0.05  |
|  GateChain |  USDT-GT |  Near-zero |

On Gate.io you can choose whichever network suits your withdrawal speed-vs-fee trade-off, making Tether token transfers flexible for both retail and institutional users.

##4. Core Utilities of the Tether Ecosystem
- Liquidity Layer – Over 70 % of spot pairs on Gate.io use USDT as the quote asset, enabling quick rotation between altcoins without touching fiat rails.  
- DeFi Collateral – Lending protocols like <a href="/ja/price/aave-aave" target="_blank" class="blog_inner_link">Aave</a>, JustLend, and <a href="/ja/price/gmx-gmx" target="_blank" class="blog_inner_link">GMX</a> accept USDT for borrowing or margin, letting farmers leverage stable yields.  
- Cross-Border Settlement – Latin-American freelancers and Asian suppliers invoice in Tether coin to dodge FX volatility and banking frictions.  
- On-Chain Payroll – Companies such as Bitwage pay contractors in USDT, delivering same-day “dollars” globally.

##5. Tether Products Beyond USDT
1. XAUT (<a href="/ja/price/tether-gold-xaut" target="_blank" class="blog_inner_link">Tether Gold</a>) – Each token equals one troy ounce of vaulted gold; trades on Gate.io as <a href="/ja/trade/XAUT_USDT?ch=ann7368" target="_blank" class="blog_inner_link">XAUT/USDT</a>.  
2. MXNT – Mexican-peso stablecoin, growing in LATAM remittance corridors.  
3. EURT & CNHT – Euro and offshore-yuan variants for FX traders seeking stablecoin pairs.

These expansions diversify revenue via issuance fees and reinforce Tether’s brand as the stablecoin powerhouse.

##6. Risk Landscape: What Could De-Peg USDT?
- Reserve Opacity – Although audits improved, skeptics fear off-balance-sheet exposure; sudden Treasury illiquidity could stress redemptions.  
- Regulatory Crackdown – A U.S. stablecoin bill mandating 100 % cash reserves might force restructuring, though Tether claims compliance readiness.  
- Banking Connectivity – Loss of correspondent banks could slow fiat inflows/outflows, widening USDT/USD spreads.

Traders mitigate these risks by monitoring Tether’s real-time transparency portal and holding alternative stables like USDC or Gate.io’s native GateUSD for diversification.

##7. How Gate.io Users Can Leverage Tether
1. Spot & Futures Base Asset – Trade thousands of pairs (e.g., <a href="/ja/trade/SOL_USDT?ch=ann7368" target="_blank" class="blog_inner_link">SOL/USDT</a>, <a href="/ja/trade/BTC_USDT?ch=ann7368" target="_blank" class="blog_inner_link">BTC/USDT</a> PERP) with deep liquidity.  
2. Gate Earn USDT Vault – Park idle USDT to earn 4–8 % APY from margin funding pools.  
3. Launchpad Participation – Most new token sales on Gate Startup require USDT sub_script_ions; holding stables avoids slippage.  
4. Low-Fee Transfers – Use TRC-20 or GateChain routes to move Tether cryptocurrency between exchanges for arbitrage.

*Tip: During network congestion, Gate.io automatically displays median confirmation times so you can pick the fastest USDT chain.

##Conclusion
As the first and largest stablecoin, Tether remains the heartbeat of crypto liquidity. Understanding what is Tether, how its reserves function, and where USDT circulates equips traders to navigate markets confidently—especially on high-volume venues like Gate.io. Whether you’re hedging, farming, or simply parking sidelined capital, the power of the Tether token ecosystem makes USDT an indispensable tool in every crypto portfolio.
