Enter your token parameters
Total supply, circulating supply at TGE, target launch price, paired asset (USDC, ETH, SOL, BNB). The calculator derives initial market cap and FDV automatically.
Pick your DEX and liquidity strategy
Choose Uniswap V2, Uniswap V3, PancakeSwap, Raydium or Curve. Pick a liquidity allocation: Conservative (10% of mcap), Balanced (5%), Aggressive (2%) or custom dollar amount.
Review depth and price impact
The tool shows required paired asset deposit, price impact at trade sizes from 0.1 to 2.5 percent of supply, sandwich attack vulnerability tier and a fit verdict on your fee tier choice.
Pool depth decides the first 72 hours.
Five things this calculator surfaces that founder Twitter threads about TGE rarely cover.
Required paired liquidity
For a target launch price and circulating supply at TGE, the calculator works backwards: how much USDC or ETH do you actually need to deposit to support your intended initial market cap? This is the number most founders underestimate by a factor of 2 to 5. Tighter answer here means fewer last-minute scrambles for paired capital.
Price impact at real trade sizes
Not "1% slippage" in the abstract. The actual percentage move when somebody buys 0.5 percent of circulating supply. Or 1 percent. Or 2.5 percent. This is the math MEV bots run before they decide to sandwich your pool. If a 1% buy moves price 9.2%, you are getting sandwiched.
Sandwich attack vulnerability
Three-tier verdict based on pool depth: High under 250k pool value, Medium 250k to 750k, Low above 750k. Below 500k total pool value, expect bot dominance of the first hour. Above 1M, sandwiches stop being economically viable for most attackers.
Fee tier fit (V3)
For Uniswap V3 and PancakeSwap V3, the calculator scores your fee tier choice against expected volatility. The 1.00% tier is correct for almost every new token launch. The 0.30% tier is for established tokens. The 0.05% tier is for stablecoin pairs. Wrong tier = bad LP economics or thin orderbook.
LP lock economics
How much you should lock and for how long. The protocol-owned LP at TGE is rug-pull-mitigation collateral, not yield-bearing capital. 12 months minimum lock on Team Finance, Unicrypt or equivalent. 24 months for long-term alignment signal. Below 12 months gets called out on Crypto Twitter as a red flag.
Cross-DEX comparison
Same math, different DEXs, different numbers. Switch between Uniswap V2, V3, PancakeSwap, Raydium and Curve to see how the same liquidity allocation plays out. Solana DEXs (Raydium) have different MEV dynamics than Ethereum L1, but the constant product math is identical.
Common questions about DEX launch liquidity
Patterns from TG3 client onboarding calls and crypto founder DMs.
How much liquidity do I need at TGE?
500k USD minimum paired liquidity is the credible floor for any serious launch in 2026. The math: thin liquidity gets sniped by MEV bots in the first three blocks and creates 40 to 80 percent immediate price collapses. A common benchmark is 5 to 15 percent of initial circulating market cap, with 10 percent being the median for DeFi launches. Below 500k total pool value, you should expect bot dominance of the first hour.
Should I use Uniswap V3 or V2 for my launch?
V3 (concentrated liquidity) gives more capital efficiency but requires active management to keep the range relevant as price moves. V2 (constant product) is simpler, more forgiving and how most TGE launches still happen. Use V3 if you have a market making partner or plan to actively manage the position. Use V2 if you are setting and forgetting. The math in this calculator is constant product (V2-style) and applies to V3 as the "infinite range" baseline.
What fee tier should I pick on Uniswap V3?
For most new token launches the 1 percent tier is correct. Volatile tokens need wider fees to compensate LPs for impermanent loss. The 0.30 percent tier is for established tokens with steadier price action. The 0.05 percent tier is for stablecoin pairs and rarely makes sense for a new token launch. Avoid the 0.01 percent tier entirely for launches.
What does sandwich attack vulnerability mean here?
A sandwich attack is when an MEV bot sees your buy order in the mempool, places a buy ahead of you, lets your trade execute at a worse price, then sells immediately after. Thin pools make these attacks profitable. The calculator shows a vulnerability tier based on pool depth: High under 250k pool value, Medium 250k to 750k, Low above 750k. Higher pool depth equals less profitable for attackers equals safer for your real users.
How long should I lock LP tokens?
12 months minimum is the market expectation. 24 months signals long-term alignment. Below 12 months gets called out publicly as rug-pull risk. Tools: Team Finance and Unicrypt are the most common LP lock services. The LP lock is independent of the team vesting schedule and applies to whoever owns the LP tokens, typically the protocol treasury. Check the Token Pre-Launch Checklist for the broader pre-TGE readiness checks.
What happens if my pool depth is too low?
Three things in roughly this order: MEV sandwich bots dominate the first hour and extract value from organic buyers. Price discovers an artificial floor below your intended launch price as bots harvest. Real holders see 20 to 60 percent immediate drawdown and complain on Crypto Twitter, which dampens momentum. The fix is mechanical: more paired liquidity at TGE. Most launches that succeed went deeper than they thought they needed to.
Does this calculator work for Solana DEXs?
Yes. Raydium V4 is supported. The math is the same constant product formula as Uniswap V2. The differences are minor (transaction costs, MEV environment, mempool visibility), not in the pool depth or price impact calculations themselves. Solana MEV is real but operates differently than Ethereum, so a "Low risk" verdict on a Solana pool is even safer than the same verdict on Ethereum.
What is impermanent loss and is it shown here?
Impermanent loss is the value drift between holding LP tokens versus just holding the underlying assets, caused by price changes between the two assets in the pool. For protocol-owned liquidity at TGE you usually do not optimize for IL since the LP is there to bootstrap markets, not to earn yield. The calculator does not surface IL as a primary metric because it is not the right input for launch liquidity decisions. Use the Tokenomics Designer for vesting + sell pressure modeling, which is the related but separate concern.
Liquidity is the most underweighted lever in a token launch
Most token launch post-mortems blame marketing, timing or product. The real cause is almost always upstream of all three: pool depth at TGE was too thin, MEV bots harvested the first hour, organic buyers got sandwiched into 30 to 60 percent drawdowns, and the chart never recovered narrative momentum.
The math is mechanical and the math is knowable. There is no debate about how a constant product pool prices a swap. There is only the question of whether the founders did the math before they shipped, or after.
Why thin liquidity is so easy to get wrong
Founder logic at TGE looks like this: we have 8 million USDC in the treasury, we want to deploy 500k to LP. That feels like a lot of money. But against a 50 million dollar target FDV with 14 percent circulating, the pool is supporting a 7 million dollar initial market cap on 500k of paired liquidity. That ratio is 14 to 1 mcap to pool. MEV bots eat 14:1 ratios for breakfast.
The fix is not philosophical. It is to run this calculator before you commit to deposit amounts, look at the price impact table, and ask whether your real users will get sandwiched on routine 0.5 to 1 percent trades. If yes, you need more paired capital or a lower circulating supply at TGE.
Liquidity decides the first 72 hours
Three things in the first 72 hours: MEV bots probe your pool depth in the first three blocks; organic discovery accelerates between hours 6 and 24; the chart pattern stabilizes around hour 48 to 72. If MEV harvests the first three blocks, organic discovery in hours 6-24 happens against a depressed chart and dampens momentum. By hour 72 the narrative is set.
Launches that compounded did the unglamorous private work of going deeper than they initially planned. 500k where they thought 250k was fine. 1M where they thought 500k was strong. Above 1M paired liquidity, sandwich attacks stop being economically viable for most attackers, and real buyers get real fills at real prices.
