Uniswap v3 changed what "LP tokens" are — your liquidity is an NFT, not an ERC-20 balance. That changes how locking works. Here's the v3-specific flow on Base, and the honest trade-offs to weigh before you choose v3 over a v2-style pool.
Can you lock a Uniswap v3 position on Base?
Yes — Team Finance supports locking Uniswap v3 LP positions on Base, including the NFT that represents your concentrated-liquidity position. The lock works on the same principle as a classic liquidity lock: the position NFT is held in an audited, non-custodial vault contract until a preset unlock date, and the lock is publicly verifiable on BaseScan. (Uniswap v4 positions are a different story — Team Finance does not currently support v4 locks on Base, and we'd rather say so here than have you discover it mid-launch. Details in the pillar guide.)
How is locking v3 liquidity different from locking v2 LP tokens?
The difference is that Uniswap v3 represents your liquidity as a unique NFT position with a price range, while v2-style pools give you fungible ERC-20 LP tokens. Three practical consequences for locking on Base:
You lock a position, not a balance. A v2 lock takes a quantity of LP tokens; a v3 lock takes the specific NFT (identified by its token ID) that holds your liquidity. Split your liquidity across several positions and each needs its own lock.
Your price range keeps working while locked. A locked v3 position still earns trading fees inside its range. Locking removes your ability to withdraw the liquidity — it doesn't freeze the position's economics.
Range choice matters more. A full-range v3 position behaves like v2 and is the simplest thing to lock for launch credibility. A narrow range is capital-efficient but can end up entirely out of range — the pool still exists, but the optics of "locked liquidity that's out of range" are worth thinking about before you set it.
How do you lock a Uniswap v3 position on Base with Team Finance?
You lock a v3 position on Base by depositing the position NFT into a Team Finance lock — one approval, one transaction. The flow:
- Create your v3 position on Uniswap on Base. Choose the pair, fee tier, and range; for launch locks, full range is the conservative default. Note the position's token ID.
- Open Team Finance and select Base. Go to team.finance, choose Lockups, and pick Base as the blockchain.
- Choose the liquidity-lock flow and connect your wallet. MetaMask and Coinbase Wallet are supported.
- Select your v3 position. Team Finance detects Uniswap v3 positions in the connected wallet so you can pick the right NFT and confirm its pair and range details.
- Set the unlock date. Same rule as any lock: pick a date you'll stand behind publicly. Extensions are possible later; early withdrawal is not.
- Pay the fee and execute. Approve the position NFT, pay the flat fee, and confirm. The lock is live and on-chain immediately.
- Publish the proof. Link the lock transaction and your Team Finance lock page wherever your community looks first — then show them how to verify it on BaseScan.
How much does it cost to lock a v3 position on Base?
Locking a Uniswap v3 position on Base costs the same flat $150 as any Team Finance liquidity lock, paid in ETH. No percentage of your liquidity, no recurring charges — the fee schedule is public in the Team Finance pricing table. Base gas adds well under a cent per transaction (as of August 2026).
Should you launch on v3 or a v2-style pool if you plan to lock?
If your only goal is a clean, legible lock for launch credibility, a v2-style pool is simpler; if you want capital-efficient liquidity and fee earnings, a locked full-range v3 position gives you both. The decision rule we'd offer: teams doing a straightforward token launch usually want v2 simplicity — one fungible LP balance, one lock, easy for anyone to read on BaseScan. Teams that understand concentrated liquidity and want their locked capital working harder choose v3 full-range. What you shouldn't do is lock a narrow-range v3 position and call it your trust signal — sophisticated buyers will check the range.
FAQ
Does a locked v3 position still earn fees? Yes. A locked v3 position keeps earning trading fees while in range; the lock only prevents withdrawing the liquidity before the unlock date.
Can I change the price range of a locked position? No. Changing range on Uniswap v3 means withdrawing and re-minting the position, which a lock by design prevents. Set the range before you lock.
Can I lock multiple v3 positions? Yes — each position NFT is locked individually, and each lock appears separately in your dashboard and on-chain.
What about Uniswap v4 on Base? Team Finance does not currently support Uniswap v4 position locks on Base. If lockable liquidity is a launch requirement, use a v3 or v2-style pool today.
