Add Liquidity to a Unichain Pool

Put money into a Uniswap market that already trades on Unichain, on v2, v3 or v4. Own the position and your deposit lands inside it instead of spawning a duplicate. 0.002 ETH.

How to Add Liquidity on Unichain

Point at the market

A token address returns the Uniswap markets carrying it here, sorted by version and tier. A pool address arrives there directly. Holdings in your wallet are listed alongside.

Deposit into yours, or open one

Choosing a position of your own leaves its boundaries as they stand and puts the money inside. Choosing only the market creates something new, which is what a changed view of the range calls for.

Name one figure

Give it either token. The counterpart follows from the live price and, on a concentrated position, from how far that price has run toward either boundary.

Sign the allowance without paying for it

Permit turns an allowance into a free signature, and Permit2 handles much of what permit does not. Paid approvals are reserved for tokens offering neither.

Read the rehearsal, then commit

Your deposit is run against live Unichain state before the wallet opens, so the figures displayed are the figures that move.

Frequently Asked Questions

Supply a token or pool address, select the market, and select your position inside it where one exists. Enter a single amount, let the market work out its partner, sign the allowance if the token permits, and confirm. All three live Uniswap versions are handled.

v4 almost certainly, and Unichain is unusual in how decisively that is true. It holds roughly two and a half times the liquidity that v3 does on this chain, while v2 has become an empty room: a rounding error in total value and, on a recent day, no trading at all. On older chains the versions coexist and the choice is genuinely open. Here the chain launched after v4 existed and the liquidity went straight to it, so a guide written about v2 pairs is describing something that barely operates on Unichain.

Yes, and this is where tooling elsewhere falls short. Rival services issue another position NFT with every deposit, so returning to the same market repeatedly leaves you holding several where one was intended, each with fees to gather and gas to close. Sending the money into the position itself avoids all of that.

Four fee tiers on v3: 0.01%, 0.05%, 0.30% and 1.00%, carrying tick spacings of 1, 10, 60 and 200. That is the same arrangement as Ethereum and most other chains, and each tier is a distinct liquidity pool with its own depth. On v4 the concept works differently, with each pool carrying whatever fee it was opened with rather than picking from a list, which is another reason the version matters more here than the tier does.

No. The boundaries live in the position and there is no way to hand it replacements, so a deposit reinforces the range you already selected. Wanting a different one means a separate position in the same market, which this will create for you.

For a concentrated position it turns on where the price sits between your boundaries: fairly even in the middle, leaning increasingly into one asset as it nears an edge, and that asset by itself once beyond. A v2 pair simply takes the ratio its reserves hold. The partner figure is quoted live rather than assumed.

No. Liquidity is written at the boundaries you chose and the recorded price is untouched by it. What a deposit changes is how far the next trade can push that price, which works in your favour rather than against it.

0.002 ETH plus gas. The only other tool with a Unichain page charges 0.015 ETH for the same deposit, and its guidance is written entirely around Uniswap v2, the version holding almost nothing on this chain. Going through Uniswap's own interface costs gas alone.

At any time and in any amount, unless it was locked or burned deliberately. Remove liquidity covers a small trim through to a complete exit and pays out earned fees at the same time.

The First Chain Where v4 Simply Won

Unichain arrived after Uniswap v4 did, and the effect on where liquidity sits is unlike any older network. v4 currently holds around two and a half times the value that v3 does here, and v2 has become a curiosity: a few tens of thousands of dollars in total, with no trading across a recent day. On Ethereum or Arbitrum the three versions genuinely coexist and picking between them is a real decision. On Unichain the decision has largely been made already.

That matters practically because most published guidance about providing liquidity is written for v2, where you hold fungible LP tokens covering the whole price curve. The only competing tool with a Unichain page has done exactly this: every question it answers is framed around v2 pairs and pool creation. Someone following it here is being taught the mechanics of the version with the least activity on the chain.

A v4 position is concentrated liquidity in an NFT covering a price range you choose, sitting under its own manager contract, with a fee set per pool rather than drawn from a fixed list of fee tiers. It is closer to v3 than to v2, and the practical consequence for a liquidity provider is that the thing you own is a specific position rather than a share of the whole liquidity pool, earning trading fees only from swaps that cross your range. Which is precisely why being able to deposit back into that position, instead of minting another one next to it, is worth having.

Four Tiers on v3, and No Tiers at All on v4

Uniswap v3 on Unichain enables four fee tiers and no others: 0.01%, 0.05%, 0.30% and 1.00%, with tick spacings of 1, 10, 60 and 200 attached to them. The same pair of tokens can therefore exist as four separate markets, each holding different liquidity at a different price, which is why a token address can return several results that look identical.

v4 abandoned the fixed list. A v4 pool carries whatever fee its creator set when opening it, so there is no tier to select and no correct answer to look up, only whatever the pool in front of you already uses. Given how much of Unichain's liquidity sits in v4, that is the more common situation here than the tier question is. The tool reads the arrangement off the market rather than asking you to know it in advance, which removes the guesswork from a decision that has different shapes on different versions.
