Launch fixed-supply tokens straight into permanently locked Uniswap V3 USDT0 pools on Stable mainnet — through a single launchpad-factory transaction.
Overview
Stego is an instant launchpad on the Stable blockchain — the USDT-native EVM chain (chainId 988). Every launch deploys a fresh immutable token and seeds 100% of its supply as a single-sided position in a new Uniswap V3 token/USDT0 pool. One transaction — the token is tradeable the moment it confirms.
Liquidity is locked forever from the first block (the position is owned by the factory and there is no withdrawal path), and a 1% swap fee on every trade is claimable as 85% creator / 15% platform.
How it works
Launching is a single transaction to the launchpad factory:
- 1You call
factory.launch(name, symbol, metadataURI, feeRecipient, initialBuy, minOut, deadline). - 2The factory deploys an immutable token (fixed 1B supply, 18 decimals — no owner, no tax, no mint).
- 3It creates & initializes a fresh Uniswap V3 token/USDT0 1% pool at the opening market cap (~$4,210).
- 4It seeds 100% of the supply as a single-sided V3 position owned by the factory — locked forever.
- 5Optionally it performs an immediate first buy for you.
After the transaction confirms, the token is live and listed. No migration step, no admin signature, no second transaction to “enable trading”.
Launch
Every token launches with a fixed 1,000,000,000 (1B) supply at 18 decimals. The token contract is immutable: no owner, no mint, no transfer tax, no pause, no blacklist. Metadata (name, symbol, offchain URI) is set once at construction and can never change.
The entire supply goes into the V3 pool as the launch position — there is no team allocation and no pre-mine. You can optionally add an initialBuy (in USDT0) to be the first buyer.
Liquidity
The launch position is minted directly on the Uniswap V3 pool and owned by the factory contract itself. The factory exposes no function to remove, withdraw, decrease or transfer that position — so the liquidity is permanently locked from the first block.
There is no LP NFT to burn or move, no migration path, and no admin key that can touch it. Verify it on-chain: the position owner is the factory and collectonly ever sends fees to the creator & platform wallets.
Graduation
Graduation is an informational milestone, not a migration. The factory marks a token graduated once the pool accumulates $20,000 of USDT0 (the gradTargetPair). Because liquidity is already locked and tradeable from launch, graduation changes nothing about the pool — it just flips a flag and emits an event.
Fees
A 1% fee applies on every swap through the pool — this is the Uniswap V3 pool fee tier (1%), not a token-level tax. Normal wallet-to-wallet transfers are completely free; the token has no transfer hook.
The collected swap fees are split when claimed:
- 185% → creator fee wallet (set at launch)
- 215% → platform fee wallet (fixed)
Fees accrue to the locked position and are claimable by anyone via claimFees(token) — funds always go to the two fixed recipients (the creator fee wallet and the platform wallet). The creator fee wallet can be changed later by its current holder via setFeeRecipient.
Network
Stego runs on Stable mainnet (chainId 988). USDT0 is both the native gas token (18 decimals as gas) and an ERC-20 (6 decimals). You only need USDT0 to transact — there is no separate gas asset.

Risk
User-created tokens are highly volatile. Most lose value and many go to zero. Always DYOR — do your own research — and never trade what you cannot afford to lose.
