What is a liquidity locker?
A liquidity locker is a smart contract that takes custody of a DEX pool's liquidity — the LP tokens of a Uniswap V2-style pair, or the position NFT of a Uniswap V3/V4 pool — and refuses to release it until a publicly visible unlock date. The pool keeps trading normally; what changes is that nobody, including the project team, can withdraw the pooled assets while the lock is active. That single property is what protects traders from the most common exit scam: pulling the pool's liquidity (a rug pull).
Titan Locker's implementation is immutable and non-custodial: each lock lives in its own dedicated contract with no admin keys, no upgrade path, and no early-withdrawal function. The unlock date can be extended, never shortened. Every lock gets a public certificate page that reads the amount, owner, and unlock time live from the chain — proof anyone can check without trusting this site.
LP tokens vs. position NFTs
What you actually lock depends on the pool generation. Uniswap V2-style pools give liquidity providers fungible ERC-20 LP tokens — locking liquidity means locking those tokens. Uniswap V3 and V4 represent each position as an NFT instead; locking liquidity means locking that position NFT. Titan Locker handles both: LP tokens are locked by amount like any ERC-20, and V3/V4 position NFTs are held by the lock contract until the unlock date.
| Pool type | What you lock | Where supported |
|---|---|---|
| Uniswap V2-style pair | ERC-20 LP tokens (any amount) | Robinhood Chain & Stable Chain |
| Uniswap V3 pool | The position NFT | Robinhood Chain & Stable Chain |
| Uniswap V4 pool | The position NFT | Robinhood Chain |
Lock Uniswap V4 positions
Uniswap V4 positions can be locked on Robinhood Chain — the position NFT is held by the lock contract exactly like a V3 position, with the same fee-collection and extend-only rules. V4 locking is still rare among lockers, so if your project launched on a V4 pool, check the certificate covers the actual position you advertise. Stable Chain has no Uniswap V4 deployment, so V4 locking does not exist there.
Collect trading fees while locked
A locked V3/V4 position keeps earning its share of the pool's trading fees. The lock owner can collect accrued fees at any time — collecting moves only the earned fees to the owner's wallet and cannot touch the locked principal. This means locking liquidity doesn't mean giving up the revenue the position generates.
Fees and supported chains
| Chain | Chain ID | Flat fee | Or in-kind | Position support |
|---|---|---|---|---|
| Robinhood Chain | 4663 | 0.025 ETH | 3% of locked amount | Uniswap V3 + V4 |
| Stable Chain | 988 | 50 USDT0 | 3% of locked amount | Uniswap V3 |
The audited V2.1 manager contract is deployed at the identical address on both chains. The contract itself is the source of truth for the live fee — the create flow reads it on-chain before you sign.
How to verify a liquidity lock
Paste the token, LP pair, or owner address into the lock checker — it searches every lock across both chains and links each result's certificate. The certificate shows the locked amount, owner, unlock date, and the lock's own contract address, all read live from the chain, so you can independently confirm every number on the block explorer.
A lock is not a safety guarantee
Locked liquidity removes one specific risk: the pool being drained before the unlock date. It does not vet the token contract (minting, blacklists, taxes), how much of the total liquidity is locked, or what else the team holds. Treat a lock as one necessary signal, not a complete safety verdict.
Frequently asked questions
What is a liquidity locker?
A liquidity locker is a smart contract that holds a DEX pool's liquidity — LP tokens or an LP position NFT — until a publicly visible unlock date. While the lock is active, nobody, including the project team, can withdraw the pooled funds, so traders can verify the liquidity can't be pulled in a rug pull. Trading in the pool continues normally the whole time.
What is the difference between an LP locker and a liquidity locker?
They are the same thing. "LP locker" emphasizes the asset being locked — LP (liquidity provider) tokens for Uniswap V2-style pools, or the position NFT for Uniswap V3/V4 — while "liquidity locker" emphasizes the outcome. Titan Locker locks both forms.
Can locked liquidity be unlocked early?
No. Titan Locker has no early-unlock, admin, or override path — the contract only releases the position to the lock owner after the unlock time passes. The unlock date can be extended to a later date, but never shortened.
What happens when a liquidity lock expires?
Nothing moves automatically. After the unlock date passes, the lock owner can withdraw the LP tokens or position NFT; until they do, the assets simply stay in the lock contract. The lock's public certificate always shows whether the position has actually been withdrawn.
Can I still earn trading fees while my liquidity is locked?
Yes, for Uniswap V3 and V4 position locks: the position keeps earning trading fees inside the pool, and the lock owner can collect those fees at any time without touching the locked position itself. The principal stays locked; only earned fees move.
Is locking liquidity the same as burning LP?
No. Burning LP tokens is irreversible — the liquidity is inaccessible forever. Locking is time-bound: the team recovers the liquidity after the unlock date. Locks signal commitment while preserving the ability to migrate liquidity later; burns are permanent by design.
Does locked liquidity mean a token is safe?
No. A liquidity lock removes one specific risk — the team pulling pool liquidity before the unlock date. It says nothing about the token contract itself (minting, blacklists, trading taxes), the share of liquidity actually locked, or the team's other holdings. Always check the lock's size and duration and the token contract before trading.
Which chains does Titan Locker support for liquidity locking?
Robinhood Chain (chain ID 4663) — Uniswap V2-style LP tokens plus Uniswap V3 and V4 positions — and Stable Chain (chain ID 988) — LP tokens plus Uniswap V3 positions (Stable Chain has no V4 deployment). The same ContractWolf-audited V2.1 contract is deployed at the identical address on both chains.
