Create a Liquidity Pool for Your Ethereum Token

Connect a wallet, paste your ERC-20 address, pick Uniswap v2, v3 or v4, and enter how much of your token and how much ETH or USDC to deposit. The ratio between the two deposits is the opening price. Review the simulation and sign once: the pool is created, funded, and optionally bought into, in that single transaction. It appears on Uniswap and the price trackers within minutes.

A liquidity pool is a smart contract holding two tokens that lets anyone swap between them without a buyer on the other side. Instead of matching orders in an order book, the pool quotes a price from the ratio of what it holds, and every trade shifts that ratio. Liquidity providers deposit both tokens into the pool and earn a share of the fee each trade pays.

Tokenry charges a flat 0.002 ETH. Uniswap charges nothing at all to open a pool, so everything else is network gas, and the version you pick matters more than anything else you decide. Creating the pool contract costs roughly 2.53 million gas on v2 and 4.69 million on v3, because both deploy a contract. v4 registers the pool inside one shared PoolManager instead, for a small fraction of either. Depositing the liquidity is on top of that, and the review shows the live estimate at the current gas price before you sign. Your deposits are not a fee: they become the liquidity and stay yours.

Uniswap publishes no minimum, so the honest answer is a mechanical one: the ETH or USDC side is what buyers spend against, and the smaller it is, the more each trade moves the price. A pool with a few hundred dollars on the quote side will swing violently on a single buy, which reads as broken to anyone looking at the chart. Deposit an amount you are willing to leave in place, because withdrawing it later moves the price and is visible on-chain.

It can be, and the mechanism is simple: every swap pays the pool's fee, and that is what liquidity providers earn, distributed proportionally to each LP's share in the pool. Note that the split changed when Uniswap governance passed UNIfication in December 2025 and switched the protocol fee on. A v2 pool's 0.3% is now 0.25% to providers and 0.05% to the protocol, and on a v3 0.3% or 1% pool the protocol takes one sixth. So 100 ETH of volume through a 0.3% pool pays providers about 0.25 ETH, not 0.3. As the pool's creator you begin as the only one to provide liquidity, so early volume accrues entirely to you.

There are three real risks worth naming. Impermanent loss, where the pool sells your token into rising demand so you end up with less of it than if you had held. Price risk on both sides, since your deposit stays exposed to the market. And contract risk, which on Uniswap is as low as it gets in DeFi given how long v2 and v3 have run, though the token you pair is entirely your own responsibility. Locking or burning the position adds a fourth consideration, because it cannot be undone.

An automated market maker always sells whichever token is rising and buys whichever is falling. If your token's price climbs after launch, the pool will have sold some of it into that climb, leaving you with more ETH and fewer tokens than if you had simply held both. That gap is impermanent loss. Trading fees offset it and on an active launch often more than cover it, but a pool is not a way to keep a position untouched.

v2 for the plainest launch: one curve covering every price, LP tokens you can burn, and the widest support from trackers and bots. v3 if you intend to manage the position, since concentrating liquidity into a range earns more per trade while the price stays inside it and nothing when it leaves. v4 for the lowest creation cost and the only permanent lock that keeps paying you fees. For a token that has never traded, v2 or a full-range v3 is the straightforward pick.

Uniswap v3 on Ethereum has four tiers, 0.01%, 0.05%, 0.3% and 1%, each with its own tick spacing. v4 works differently: the protocol lets a pool set any fee at all, so the four options offered here are Tokenry's shortlist rather than a limit Uniswap imposes. Most new token pools use 0.3%, and 1% suits a thin or volatile pair where each trade should pay providers more. The lower tiers exist for stable, heavily traded pairs. Whichever you pick is fixed once the pool exists.

A first buy is an amount of ETH swapped for your own token immediately after the pool is created, inside the same transaction. It matters because sniper bots watch mainnet for new pools and buy in the same block one appears, then sell into the people who arrive afterwards. A buy that executes before the creation transaction ends cannot be front-run. The tokens land in your wallet, and the first buy is available when pairing against ETH.

Both make the liquidity permanent, which is what buyers check first. Burning sends the LP tokens or the position NFT to the dead address: on v2 nothing is lost because fees compound into the pool itself, while on v3 the position's fees become unclaimable by anyone. Locking is a v4 option, where the position goes to a fee forwarder contract deployed for your pool from Uniswap's own liquidity launcher code. Nobody can ever withdraw the liquidity, and its trading fees still come to you.

On v2 you receive LP tokens, ERC-20 tokens that represent your share of everything in the pool, which is why burning them is the classic proof that liquidity is locked. On v3 and v4 you receive a position NFT instead, holding your range and your unclaimed fees. Either way it goes to your wallet in the creation transaction, unless you chose to burn or lock it.

Usually not. Tokens created with Tokenry include a permit function, so the approval is a free message you sign rather than a transaction you pay for. A wallet that has used Uniswap before can sign a Permit2 message for any token instead. Only tokens with neither need a plain approve transaction first, and the tool tells you which case applies before you start.

It runs your exact transaction against live mainnet state and reports the result before your wallet opens. You see how many tokens reach the pool, the opening price, the first-buy estimate and the gas. If it would revert you get the reason in plain words, such as a transfer tax larger than your slippage, a pool that already exists at a different price, or a token that blocks transfers until trading is switched on.

On v2, yes. The launcher moves tokens straight from your wallet into the pair, so the owner exclusion most tax tokens carry still applies, and if a cut is taken anyway the ETH side is scaled to match what actually arrived so your intended price holds. Uniswap v3 and v4 verify the amount they receive and reject short transfers, so a taxed token stays on v2 unless you exclude the launcher address from fees first.

The tool detects it and joins it rather than building a second one. On v2 both sides are sized to the existing ratio and the remainder is refunded to you. On v3 and v4 the pool's current price is used for your position. To open a genuinely separate market, pick a different fee tier or the other quote asset.

On decentralized exchanges, effectively yes. Uniswap has no listing process and no approval to apply for: the pool is the listing, and the token becomes tradable the moment the transaction confirms. DexScreener and similar trackers chart it once trades happen. Centralized exchange listings and CoinGecko or CoinMarketCap entries are separate applications, and a live pool with real volume is usually a prerequisite rather than a substitute.

Yes, unless you burned or locked the position. Use add liquidity to deepen the pool later, or remove liquidity to withdraw any share from 1% to 100%, which on v3 and v4 pays out the position's unclaimed trading fees at the same time.
