Unichain ERC-20

Create a Liquidity Pool on Unichain

Unichain is Uniswap's own network, so there is no exchange to choose here, only a version. Deploy a v4, v3 or v2 pool for your ERC-20 in one signed transaction, funded on both sides at a starting price you set, with your own opening trade included. 0.002 ETH.

Unichain

Create a liquidity pool

Deposit initial liquidity and open trading for your token on Unichain.

Exchange

Only one exchange on this chain has the liquidity and routing to matter, so the pool goes here.

Pool version

A simple constant-product pool. One price curve, no range to manage, and the LP position is a plain token you can burn.

Simplest and cheapest to create. Your liquidity covers every price, so the pool never goes idle. This is what most token launches use, and the only version that supports tax tokens.

Initial liquidity

Pick your token and what to pair it with, then deposit both sides. The ratio sets the opening price.

Your token

Paste a contract address or pick one of your tokens.

Unichain native coin

Opening priceEnter both amounts

Burn LP tokens Free

The LP tokens go to the dead address. The liquidity can never be pulled. v2 fees compound into the pool itself, so nothing is claimable either way. This cannot be undone.

First buy Free

Buy your own token inside the pool creation transaction, so it executes before anyone else can trade.

How to Create a Liquidity Pool on Unichain

Point your wallet at Unichain

Gas is paid in ETH and the chain has no token of its own, so all you need is ETH held on Unichain itself. Any wallet that can add a network will do.

Pick the version, not the exchange

Every pool here is a Uniswap pool. v4 takes the large majority of new pools and is far cheaper to open, v3 gives you a fee tier and a range and still carries more of the trading, and v2 is available though almost nobody uses it on this chain.

Supply the token and its counterpart

Enter your ERC-20 address or choose one you minted here, then set ETH or USDC against it. The two quantities you commit are what the market opens at, calculated for you as you type.

Choose an opening trade and the fate of the position

A portion of ETH can be spent buying your token as part of the launch. The position itself can stay in your hands, be destroyed, or on v4 be locked away while its earnings still reach you.

Review the rehearsal and confirm

Before anything is signed the transaction is run against current chain state and the result laid out, failures included. Confirming once does all of it.

Frequently Asked Questions

Use a connected wallet holding ETH on Unichain, choose a Uniswap version, give the tool your ERC-20 token address, set ETH or USDC as the other half of the token pair, and enter both amounts. The ratio of tokens you commit fixes the starting price. Confirm the transaction once and pool creation, adding the initial liquidity, your opening purchase and the LP decision all happen together.

In practice, Uniswap. Unichain was built by Uniswap Labs, so unlike every other network there is no established third-party decentralized exchange to weigh up, and the routing, the interface and the liquidity are all one ecosystem. That makes this the one chain where the decision collapses from which exchange down to which version, which is a simpler question with a clearer answer.

An L2 built by the team behind Uniswap, running on the OP Stack and settling to Ethereum mainnet, with no token of its own and gas paid in ETH. It is a DeFi chain in the literal sense: powered by Uniswap rather than merely hosting it. The honest case for launching a pool here is not that it is busy, because it is not, and it sees a small fraction of the new pools that Base does. The case is that it is the chain where Uniswap's newest machinery is first-class rather than an afterthought, which shows up on-chain in what people actually deploy.

v4 for most launches, with one caveat worth knowing. v2 is the easy exclusion: no new v2 pairs were created here in a recent week and v2 did none of the chain's trading volume, so its million-pair counter is an artefact of one automated run rather than a sign of life. Between v3 and v4, v4 costs roughly a thirtieth of the gas to open, because a pool is a storage entry in a shared contract rather than a freshly deployed one, and it is the only version where a permanently locked position still pays out its fees. The caveat is that v3 still carries more trading volume on this chain than v4 does, so if being routed to by existing flow matters more to you than creation cost, v3 remains defensible.

Less than almost anywhere, and this is measurable rather than a claim. Unichain has no chain-wide public queue of pending transactions, so the classic attack of spotting a pool creation before it lands has no entry point. Sampling a minute of activity, 487 transactions were mined and exactly one of them was visible in advance through a provider's own pending feed, which is under a quarter of one percent. What remains is reaction rather than interception: the chain publishes preconfirmations every fifth of a second, and something watching those can act in a later one. An opening trade carried inside the creation transaction is ahead of even that, because it settles before there is anything to react to.

A liquidity pool is a pair of balances held by smart contracts, and a price is implied by the ratio between them rather than by any order book. Every swap shifts the ratio, which is what moves the price. Deposit into a v2 pool and you receive LP tokens, a fungible claim on your share of everything inside; v3 and v4 issue a position NFT instead. Either way the claim is what entitles you to a cut of the fees, and what you do with it afterwards is the decision holders pay most attention to.

They are unrelated activities that get bundled together because both are described as earning yield. Staking commits a single asset to help secure a network or a protocol and pays a return for doing so, with your position denominated in that one asset throughout. Providing liquidity commits two assets to a trading pool, earns a share of swap fees, and continuously rebalances between the two as the price moves, so you end up with a different mix than you deposited. Creating a pool for a token you just launched is the second thing, not the first. Note also that Unichain has no token of its own to stake.

The income is the swap fee, divided between liquidity providers according to each one's share of the pool, and as the only provider at launch that is all of it. Set against that is the rebalancing: an automated market maker sells whatever is climbing, so a token that appreciates leaves you holding less of it and more ETH than you deposited, which is worth less than simply having held both. Fees have to out-earn that gap for the position to be ahead. On a pool with genuine trading they often do; on a quiet one they will not.

You set it implicitly, by choosing what to deposit. Two million tokens against 4 ETH opens the market at 0.000002 ETH per token, and multiplying that by your total supply gives the valuation you are implying, which is usually the number worth sanity-checking. To hit a specific price, divide the ETH amount by the token amount and adjust until it matches. The figure updates live in the form so you are not doing this blind.

The 0.002 ETH service fee is essentially the whole cost of creating a pool here. Uniswap takes nothing for opening one, and gas on Unichain is a fraction of a cent, particularly on v4 where no new contract is deployed. What you add as initial liquidity is not spent; it becomes the pool and stays your claim unless you deliberately give that up. Compare that with Ethereum mainnet, where gas alone can exceed the service fee several times over.

On v3 the chain carries the usual four, 0.01%, 0.05%, 0.3% and 1%, and anything newly launched belongs in the upper two, since a thin and volatile pair should pay its liquidity providers properly. The lower pair exists for stablecoins and assets that track each other. v4 imposes no fixed list at all, so the options presented here are our shortlist rather than a rule of the protocol.

Yes, and it is part of the same confirmation rather than something you chase afterwards. Nominate an amount of ETH and it is spent on your token within the launch transaction, which means the purchase is already settled by the moment a finished pool becomes visible to anything watching. The tokens go to the wallet that signed, and this works when ETH is the counterpart asset.

That is up to you and the three options are meaningfully different. Retaining it keeps your ability to withdraw, which anyone reading the chain can see and will factor in. Destroying it makes the liquidity permanent, at the cost on a v3 or v4 position of also forfeiting every fee it would have earned, since a single NFT carries both. The exception is a v4 lock, where a forwarding contract deployed for your pool holds the position beyond anyone's reach while the fees continue arriving in your wallet.

It is live and visible as soon as the transaction lands, tradable with no listing process and nobody to ask. Uniswap's own interface routes to it immediately, and trackers such as DexScreener begin charting once a trade exists, which an opening purchase provides straight away. From there you can manage liquidity like any other position, deepening or drawing it down at will.

Three things, in order of how often they are got wrong. The starting price, because a pool opened far from what the token is worth is an arbitrage that somebody else collects within minutes. The depth of the ETH side, because that decides how much volatility an ordinary trade produces on the chart. And what happens to the position, because burning and locking cannot be reversed and are the one decision here you make exactly once.

Native USDC issued by Circle, at 0x078D...7AD6, which is the address Circle itself publishes for this chain. That is worth stating because several other networks carry both a native and an older bridged version of the same ticker, and a pool built on the wrong one sits away from the routing. Unichain has no bridged USDC.e to confuse it with, so this is one of the few chains where the question has a single answer. Supply is modest, in the low tens of millions, which is another reminder to size a pool for the pond it is in.

Usually not. Anything deployed through Tokenry supports permit, so the approval is a signature rather than a paid transaction, and Permit2 covers many other tokens if the wallet has used Uniswap before. Only a token supporting neither needs a conventional approval first, and the tool identifies that before you commit to anything.

On v2 only. Tokens travel straight from your wallet into the pair on that route, so an owner exemption written into the contract still applies, and where a cut is taken regardless the ETH side is adjusted to preserve the price you intended. The concentrated versions check that the amount received matches the amount promised and decline the deposit when they differ.

Yes, so long as the position was not made permanent. Add liquidity tops it up at the prevailing ratio, and remove liquidity returns any portion between 1% and 100% together with the fees a v3 or v4 position has accumulated.

The One Chain Where There Is No Exchange to Choose

On every other network, opening a pool starts with a decision about venue. There is a large native exchange with its own incentive scheme, there is Uniswap, and picking between them means weighing where the volume sits against where a new token can actually get traction. Unichain removes that question by construction. It was built by Uniswap Labs, so Uniswap is not one option among several, it is the house.

What remains is the version, and that is a more tractable decision with a clearer answer than the venue question ever had. Everything below is about choosing between v4, v3 and v2 rather than about which exchange deserves your liquidity. If the token does not exist yet, create an ERC-20 on Unichain first.

v2 Is Finished Here, and v4 Costs a Fraction of v3

Two facts settle the version question on this chain, and neither is the one you would guess. The first is that v2 is effectively dead here. Its factory shows over a million pairs, which sounds enormous until you look at when they appeared: the overwhelming majority came from a single automated run in late 2025, the paired contracts often do not even implement a symbol, and in a recent week not one new v2 pair was created. Uniswap v2 accounted for none of the chain's trading volume over the last month. Treat that million-pair counter as noise rather than as evidence of anything.

The second is cost. Creating a v3 pool here means deploying a contract, and a real one measured at roughly 5.2 million gas. A v4 pool is a storage entry inside a single shared contract, and a real creation measured at about 172,000. That is a thirtyfold difference on the same chain in the same week. Since gas on Unichain is negligible either way, this matters less to your wallet than it sounds, but it does tell you which version the chain is actually built around.

One thing worth not overstating, because it gets claimed a lot: v4 taking most new pools is not a Unichain quirk. Roughly seven in eight new Uniswap pools here are v4, and the figure on Base is almost exactly the same. The genuinely surprising number runs the other way. On Uniswap's own chain, v3 still does more trading volume than v4, despite v4 holding more than twice the liquidity. The newest version has the pools and the deposits; the older one still has the flow.

An Honest Word About How Busy Unichain Is

Unichain is not where the volume of new launches is. Over a recent thirty-day window it saw roughly a hundred new Uniswap pools. Base, over the same period, saw well over a hundred thousand. Optimism, itself a quiet chain by comparison with Base, saw around five times what Unichain did. Anyone telling you this is where the crowd is has not counted.

There is a sharper version of the point. When Uniswap Labs launched its own consumer token-launch product in August 2026, it built it for Robinhood Chain, and the announcement did not mention Unichain. Read that for what it is: a signal about where the launches are, from the people best placed to know.

None of which is automatically an argument against launching here. A pool on Unichain is not competing for attention with thousands of same-day pools, gas is close to free, and the Uniswap tooling is as current as it gets because the people who build Uniswap build the chain. But choose it because you want those properties, not on an expectation of passing traffic. Size the pool for a small pond, and remember that liquidity makes a token buyable rather than wanted.

After the Pool Exists

The pool routes on Uniswap the moment it confirms and appears on the usual trackers once trading starts. Gas here is cheap enough that nothing about maintaining a position is a budgeting decision, so adding liquidity as volume justifies it and removing some when it does not are both routine rather than events.

The token contract is the other half of what people check. The Unichain token manager handles minting, limits and renouncing ownership, and a renounced contract alongside liquidity that cannot be pulled is the pair of signals most buyers look for before anything else.
