Single-Sided Liquidity

Single-sided liquidity is the practice of providing only one token to a trading pool instead of the usual pair. In token launches, the most common form places the new token in a concentrated price range set above the current price, so that buyers supply the other side of the pool as they trade. Instead of pairing a new token with capital such as ETH or USDC, the creator deposits only the token itself.

This works because concentrated liquidity AMMs in the style of Uniswap v3 let providers choose exactly where their liquidity sits. A position placed entirely above the market price consists only of the token being sold. As buyers push the price up through that range, the pool sells tokens and accumulates the quote asset, so the position behaves like a standing sell order that converts supply into two-sided liquidity as demand arrives.

This mechanic powers pump-style token launches. A launchpad can deposit the token supply single-sided, meaning a live market exists from the first block without the creator fronting any capital, and price discovery starts at the bottom of the range. A launchpad built on this pattern commonly pairs it with a liquidity lock, holding the resulting position for years so the creator cannot withdraw it.

Single-sided seeding lowers the barrier to launching, which cuts both ways: it enables fair launches with no privileged insiders, but it also makes low-effort tokens cheap to spin up. The quote-asset side of the pool only exists after real buying, so early liquidity is thin and prices are volatile, and none of this says anything about whether the token itself has value.
