What Is gUSDT? Trading Memecoins in USDT on Stable Mainnet
By Elena Vasquez, DeFi Protocol Analyst ·
What Is gUSDT?
gUSDT is the USD-pegged gas token used to pay fees and settle trades on Stable Mainnet (chainId 988), Tether's USDT-native Layer 1. First introduced as gUSDT (Stable's USD-pegged gas token, renamed USDT0 under Stable v1.2.0), it lets every transaction and memecoin trade settle in a dollar-denominated unit instead of a volatile gas coin. StablePump, a fair-launch bonding-curve memecoin launchpad on Stable Mainnet (chainId 988), prices every token curve in gUSDT and graduates tokens to an on-chain AMM at 20,000 gUSDT.
Because gUSDT tracks the US dollar one-to-one, the price you see on a StablePump chart reflects real demand for the token itself — not the swings of an underlying gas currency. That single design choice is what makes a "stable" memecoin launchpad different from Solana or Ethereum launchpads, where fees and quotes ride on SOL or ETH.
gUSDT vs USDT: How They Relate
gUSDT is the on-chain gas form of Tether's USDT on Stable Mainnet, pegged 1:1 to the US dollar and used to pay network fees natively. On most blockchains USDT is a regular token that sits on top of a separate gas coin; on Stable, the USD-pegged unit is the gas, so you never need a second asset just to transact. One gUSDT is designed to always be worth one US dollar, the same peg USDT maintains across every chain.
According to Tether's 2025 announcement of Stable, the chain was purpose-built to make USDT-denominated value the native medium of the network rather than a bolt-on stablecoin. This is the structural reason StablePump can quote a token's entire life — launch, bonding curve, and graduation — in dollars.
gUSDT vs a Volatile Gas Token: Why It Matters in 2026
Pricing a memecoin in gUSDT removes the "double bet" that traders take on chains with volatile gas tokens. On Solana or Ethereum, a token's quoted price moves with both its own demand and the price of SOL or ETH; on Stable Mainnet, the gUSDT peg holds the denominator steady so only token demand moves the number.
| Factor | gUSDT (Stable Mainnet) | Volatile gas token (SOL / ETH) |
|---|---|---|
| Price stability of the unit | Pegged 1:1 to USD | Fluctuates with the market |
| Fee predictability | Fees quoted in dollars | Fee value swings with gas price |
| Market-cap clarity | Reads directly in USD | Must convert from SOL/ETH |
| Trader exposure | Token demand only | Token demand + gas-coin price |
| Used on StablePump | Yes — curves priced in gUSDT | No |
Bottom line: If you want a memecoin's chart to reflect the coin and nothing else, a USD-pegged unit like gUSDT is clearer; if you specifically want exposure to SOL or ETH alongside the trade, a volatile gas token still suits you.
Why StablePump Prices Bonding Curves in gUSDT
StablePump prices every bonding curve in gUSDT so that a token's market cap, its 20,000 gUSDT graduation target, and its fees are all measured in the same stable dollar unit. Each StablePump token launches with a fixed supply of 1,000,000,000 tokens on a curve where the earliest buyers pay the lowest gUSDT price and the price climbs deterministically as supply is bought.
This matters for fees, too. StablePump's 1.25% trading fee — split as 0.95% to the protocol and 0.30% to the coin's creator — and its flat graduation toll of roughly 2 gUSDT are both denominated in gUSDT. A creator therefore earns their 0.30% share in a stable dollar unit rather than a coin whose value could drop before they cash out.
According to Dune Analytics dashboards tracking pump.fun (2025), fewer than 2% of tokens launched on a bonding curve ever reach graduation, which means the vast majority of trading activity happens while a token is still on the curve — exactly the phase StablePump denominates in gUSDT.
How to Get gUSDT for Trading and Launching
You get gUSDT by adding Stable Mainnet to your wallet and funding it with USDT-denominated gas, either by bridging USDT to Stable or acquiring it on the network directly. You need gUSDT for two things on StablePump: the small network fee to launch or trade, and your first buy from the bonding curve.
- Add Stable Mainnet — Configure your wallet for chainId 988 using Stable's public RPC.
- Fund with gUSDT — Bridge or acquire USDT-denominated gas so you can cover fees and your first curve buy.
- Open StablePump — Connect the funded wallet to launch a coin or buy an existing one, all priced in gUSDT.
You can confirm any token, balance, or transaction on the Stable block explorer at stablescan.xyz.
What Pricing in a Stable Unit Means for Memecoin Traders
Pricing in gUSDT means a StablePump memecoin's numbers speak in dollars, which changes how traders read a chart and plan an exit. A token quoted at 0.0004 gUSDT is quoted at 0.0004 US dollars — no mental conversion from SOL or ETH, and no risk that a 20% "gain" is really the gas coin moving underneath the trade. For a fixed supply of 1,000,000,000 tokens, market cap reads directly: multiply the gUSDT price by the supply and you have the dollar valuation.
This clarity compounds at the two moments that matter most on a launchpad: the entry, where you see the exact dollar cost of your first curve buy, and graduation, where the 20,000 gUSDT threshold is a plain $20,000-denominated target rather than a moving number tied to a volatile asset. For traders comparing many launches quickly, a stable denominator removes a whole layer of noise.
gUSDT Is Being Renamed USDT0 (Stable v1.2.0)
Under Stable v1.2.0, the gas unit formerly labeled gUSDT is renamed USDT0. The peg, the 1:1 USD value, and the role as native gas are unchanged — only the ticker is updated. If you see USDT0 in a wallet or on stablescan.xyz, it is the same asset that older guides and StablePump curves refer to as gUSDT. Amounts such as the 20,000-unit graduation target are identical whether written as 20,000 gUSDT or 20,000 USDT0.
Frequently Asked Questions
- What is gUSDT?
- gUSDT is the USD-pegged native gas token of Stable Mainnet (chainId 988), Tether's USDT-native Layer 1. It settles fees and trades in a dollar-denominated unit, so on StablePump every memecoin bonding curve is priced in gUSDT and graduates to an AMM at 20,000 gUSDT. It is being renamed USDT0 under Stable v1.2.0.
- Is gUSDT the same as USDT?
- gUSDT is the on-chain gas form of Tether's USDT on Stable Mainnet, pegged 1:1 to the US dollar. Functionally it holds the same dollar value as USDT, but it doubles as the network's native gas token, so you pay fees in it directly instead of needing a separate volatile gas coin.
- Why do StablePump tokens trade in gUSDT?
- StablePump prices tokens in gUSDT so a memecoin's market cap, fees, and 20,000 gUSDT graduation target are all measured in a stable dollar unit. This keeps the chart reflecting token demand rather than swings in an underlying gas coin, and it pays creators their 0.30% trade-fee share in dollars.
- How do I get gUSDT on Stable Mainnet?
- Add Stable Mainnet (chainId 988) to your wallet, then fund it with USDT-denominated gas by bridging USDT to Stable or acquiring it on the network. You need gUSDT for the network fee plus your first bonding-curve buy on StablePump. Verify balances on stablescan.xyz.
- Are StablePump fees paid in gUSDT?
- Yes. StablePump's 1.25% trading fee (0.95% to the protocol, 0.30% to the coin's creator) and its flat graduation toll of roughly 2 gUSDT are both denominated in gUSDT. Under Stable v1.2.0 these same amounts are expressed in USDT0, the renamed gas unit.
