Stable is the native DEX of Stable Chain (chain id 988) — a Uniswap V2-style automated market maker. The twist: Stable Chain's gas token is a stablecoin (gUSDT), so every pool, price and position is denominated in dollars, not ETH.
Two contracts do the work: a Factory that deploys pools, and a Router that you interact with to swap and add/remove liquidity. Each pool is a Pair holding two tokens and pricing them by the constant-product formula x · y = k.
Prices are set by the ratio of reserves in a pool, not an order book. A swap moves the reserves along the x·y=k curve; larger trades relative to pool depth get more slippage. The Router computes outputs with getAmountsOut and can route through multiple pools.
The launch pool is STABLE / gUSDT (the wrapped native, WgUSDT). Because gUSDT is a dollar stablecoin, the pool quotes $STABLE directly in USD — no ETH leg, no dollar conversion needed.
Provide both sides of a pair to become a liquidity provider. You receive LP tokens — a standard, transferable ERC-20 representing your share of the pool. Redeem them any time via the Router to withdraw your share of the reserves plus accrued fees.
removeLiquidity — LP is an ERC-20, not an NFT.Every swap pays a 0.30% fee that stays in the pool, growing every LP's share — that's the yield for providing liquidity. An optional protocol fee (a slice of the 0.30%) can be switched on at the Factory; it is disclosed on-chain when active.
$STABLE is the token of the DEX — a clean, ownerless, fixed-supply ERC-20.
| Parameter | Value |
|---|---|
| Total supply | 1,000,000,000 STABLE |
| Decimals | 18 |
| Tax / mint / owner | none — immutable |
| Launch pool | STABLE / gUSDT |
| Priced in | gUSDT (USD) |
Supply is minted once at deploy. A share is seeded into the STABLE/gUSDT pool to open the market; the rest is held for liquidity, incentives and the treasury as disclosed at launch. No mint, no admin — nothing to rug.
Factory, Router and $STABLE addresses publish at launch and are verifiable on stablescan.xyz.

Is my LP an NFT? No — V2-style LP tokens are fungible ERC-20s. Transferable and composable.
Slippage? Set by pool depth and trade size, shown before you confirm. Thin pools move more.
Not investment advice. Providing liquidity carries impermanent-loss and smart-contract risk. DYOR.
