How to Lock Uniswap LP Tokens on Arc

Uniswap is live on Arc from day one, which means the first serious question buyers will ask about your Uniswap-pooled token arrives on day one too: is the liquidity locked? This guide walks through locking Uniswap liquidity on Arc with Team Finance — including the part most guides skip, the difference between locking v2 LP tokens and v3 position NFTs.

Why lock Uniswap liquidity at all?

An unlocked pool can be drained by whoever holds the LP tokens — that withdrawal is what a rug pull is. Locking deposits your LP position into a time-locked contract that nobody, including you, can open before expiry, and the lock is publicly verifiable on-chain. On most chains this is best practice; on Arc it's closer to an entry requirement. The network's founding validators include BlackRock and Visa, its users skew diligence-heavy, and everything is inspectable on Arcscan — projects that can't show a lock will simply be filtered out. The general case is covered in how to lock liquidity on Arc; this guide is the Uniswap-specific walkthrough.

v2 LP tokens vs v3 position NFTs: which do you have?

Uniswap deployments come in two generations, and they represent your liquidity differently — which changes what you're locking.

v2-style pools issue fungible ERC-20 LP tokens. Add liquidity to a pair and you receive a token balance proportional to your pool share. Locking means locking that ERC-20 balance, and partial locks are simple — lock 95%, keep 5%.

v3-style pools issue a position NFT. Concentrated liquidity means your position has its own price range and fee accrual, so it's represented as a unique ERC-721. Locking means locking that specific NFT, whole — a position locks or it doesn't. If you want a partial lock in v3, mint two positions and lock one.

Check which you hold before starting: a token balance in your wallet means v2-style; a position in Uniswap's "Positions" view backed by an NFT means v3. Team Finance supports locking both on Arc.

How do you lock, step by step?

Step 1 — Create your pool and receive your position. Pair your token with USDC — on Arc it's the gas token and the natural unit of account, so token/USDC is the pair buyers expect. Add liquidity on Uniswap on Arc; you'll receive LP tokens (v2) or a position NFT (v3).

Step 2 — Open Team Finance, choose Liquidity Locks, select Arc. Connect the wallet that holds the position. The app detects your Uniswap LP tokens or position NFTs automatically.

Step 3 — Set amount and duration. For v2, choose what share to lock — 100% is the strongest signal, and anything under about 80% invites questions. For v3, select the position NFT to lock. Duration: 6–12 months is the credible floor, and serious projects lock longer. Locks can be extended later but never shortened — the contract enforces it.

Step 4 — Review the fee and confirm. Team Finance quotes a flat fee in USDC — never a percentage of your liquidity or supply — so you know the exact cost before signing. Confirmation is sub-second on Arc.

Step 5 — Publish your proof. You get a public lock page and certificate URL. Pin it in your Telegram, put it on your site, link it in your docs — and point skeptics at the on-chain record, which anyone can check via the lock verification guide or directly on Arcscan.

When should you lock?

Before you announce, not after. The gap between "pool is live" and "lock is visible" is exactly the window in which diligent buyers pass on you — and on Arc, diligence is the norm. Locking belongs on your launch checklist alongside team token vesting, sequenced before any marketing push. If you're still pre-launch, the whole path — mint, pool, lock — is rehearsable on Arc testnet today with faucet USDC.

FAQ

Can I lock Uniswap v3 positions on Arc, or only v2 LP tokens? Both. v2-style ERC-20 LP tokens lock as a token amount; v3 position NFTs lock as whole positions. Team Finance supports both on Arc.

What happens to trading fees while a v3 position is locked? The position keeps earning fees inside the pool as it normally would; what the lock prevents is withdrawing the liquidity itself before expiry.

Can I unlock early if I need the liquidity back? No. Locks can be extended, never shortened or opened early — that irreversibility is what makes the lock meaningful to buyers.

What does locking cost on Arc? A flat fee quoted in USDC upfront, plus Arc gas measured in fractions of a cent (testnet fees have averaged around $0.004). You'll know the total before you sign.

How do buyers verify my lock is real? Via your public Team Finance lock page and on-chain on Arcscan. The verification guide shows the exact steps.

Does this work before mainnet? Yes — the full flow runs on Arc testnet now (chain ID 5042002, faucet USDC from faucet.circle.com) and works identically at mainnet on September 16, 2026.
