Is liquidity locked on Doppler launches?

Short answer: on Robinhood Chain, yes, and permanently, for almost every Doppler launch. The launch liquidity sits in Uniswap V4 positions owned by Doppler's pool initializer contract, and on the launches we checked there is no code path left that can take it out. Not the creator, not the launchpad, not Doppler. What Doppler does not lock is everything around the pool: a creator's vested allocation once it vests, tokens bought from the pool, fee income, and any liquidity someone adds later.

How a Doppler launch works on Robinhood Chain

Doppler is launch infrastructure rather than a single launchpad. Every launch, whichever front end it comes from (Bankr is one), goes through one contract, the Airlock (0xeb7C…0862), which is given four modules: a token factory, a governance factory, a pool initializer and a liquidity migrator. In one transaction the Airlock deploys the token, hands the tokens for sale to the initializer, which builds the pool, and registers the migrator for later.

• Token. Each token is a minimal clone of DopplerERC20V1 (0x3Be8…C599 or 0xeDf3…50f8), deployed by a DopplerERC20V1Factory (0x1b37…b69a or 0xf154…2cE5). The token has no mint function, so supply is fixed at launch.
• Pool. The DopplerHookInitializer (0x4e34…a544) creates a Uniswap V4 pool on the chain's PoolManager (0x8366…0951) with itself as the hook, and spreads the sale supply across a set of curve positions. Swaps can also call a "Doppler hook" plugin; on the launches we sampled that was a RehypeDopplerHookInitializer (0x6f02…0F77, 0x9982…FdBB or 0xe2AE…78b6), which handles fees, buybacks and fee reinvestment.
• Migrator. On the launches we sampled, the NoOpMigrator (0xba2F…5A0e).

So when someone asks whether "Doppler liquidity" is locked on Robinhood Chain, they are almost always asking about the DopplerHookInitializer.

The hook, and why beforeRemoveLiquidity isn't the lock

People who read a Doppler pool on an explorer often look for a beforeRemoveLiquidity hook that reverts for outsiders. There isn't one. In Uniswap V4 a hook's permissions are encoded in the last bits of its address, and the DopplerHookInitializer's address (ending a544) switches on beforeInitialize, afterAddLiquidity, afterRemoveLiquidity, afterSwap and afterSwapReturnDelta. beforeRemoveLiquidity is off, which matches the getHookPermissions() function in the source.

The lock comes from ownership instead. Uniswap V4 files every position under the address that created it, and only that address can shrink it. The initializer mints the launch positions itself, so it is the only account that can ever remove them, and its source has exactly one function that does: exitLiquidity. That function:

• can only be called by the Airlock, and only as part of Airlock.migrate();
• requires the launch's status to be Initialized.

When a launch is created with fee beneficiaries, the initializer stores its status as Locked instead and emits a Lock event. Nothing in the contract moves a launch from Locked back to Initialized. The one other exit, graduate(), needs a Doppler hook with the graduation flag; the Rehype hooks we checked are enabled with the initialization and swap flags only (value 3), and every launch in our sample has its timelock set to 0x…dEaD or the zero address, so no account can attach a different hook. Even a graduation would set Graduated, which exitLiquidity also refuses.

The Rehype hook adds a second layer. It reinvests part of the swap fees as a full-range position held by the hook contract. In the verified source of the Rehype deployments on Robinhood Chain, the hook's own code only ever adds to that position, so this liquidity only grows.

What happens at "migration"

On Base, Doppler launches are often described as moving liquidity to a new pool when the curve completes. On Robinhood Chain that step essentially does not happen:

• Every launch in our sample was registered with the NoOpMigrator, whose migrate() always reverts with CannotMigrate(). A call to Airlock.migrate() for such a token reverts as a whole, so the pool is never emptied.
• Across the Airlock's entire history on Robinhood Chain there is exactly one Migrate event, for a token named "Pump Test 1" launched through the Lockable V3 initializer.

That single case shows why the migrator matters. It used the UniswapV2MigratorSplit (0xB050…a333), whose source sends 95% of the new Uniswap V2 LP tokens to the launch's timelock address and only 5% to the UniswapV2Locker (0x63f6…42a5), with a minimum lock of 365 days. If a future launch is set up with that migrator, the lock picture is very different, so check which migrator a token uses rather than assuming.

The Lockable V3 launches follow the same pattern as the hook launches: in a sample of 80, 78 were Locked with the NoOpMigrator, and 2 were Initialized with the V2 split migrator.

What Doppler does not lock

• Vested creator allocations, once they vest. DopplerERC20V1 has vesting built in. Reserved tokens are held by the token contract and released to each beneficiary on a schedule with a cliff and a duration. The contract allows up to 80% of supply to be reserved, and a schedule with a duration of zero vests instantly. In our sample, 283 of 400 launches reserved nothing, 113 reserved 15%, and 4 reserved 1% to 2%, some of it vesting instantly.
• Tokens bought from the pool. A dev buy or any later purchase is an ordinary balance.
• Fee income. Trading fees paid out to beneficiaries and integrators arrive liquid.
• Liquidity added later. The hook does not restrict adding liquidity, so anyone can add a position to a Doppler pool, and that position belongs to whoever added it and can be withdrawn at any time.

Bankr is a Doppler launchpad

Bankr's own support documentation says its launches use Doppler and deploy to Robinhood Chain by default, and the chain agrees. Bankr tokens are created by the Airlock above, with the DopplerHookInitializer and the NoOpMigrator, and their metadata names Bankr as the launch provider. One example is 0x4346…Fba3: getState returns Locked, 15% of supply is vested to the creator with a 30-day cliff over one year, and the pool's fee beneficiaries are the creator at 95% and Doppler's protocol owner at 5%, the minimum share the contract requires.

The vesting length has changed. Bankr launches from early July 2026 vest over two years; later ones vest over one year, which is what Bankr's documentation now describes, and Bankr lets a creator switch vesting off entirely. Read the token's own schedule rather than relying on the default. Our guide to vesting alongside a Bankr launch covers what that schedule leaves out.

How to check a specific Doppler token

1. Open the token on Blockscout. A Doppler token shows up as a minimal proxy of DopplerERC20V1, so read it through the proxy view, which uses the verified DopplerERC20V1 code. owner() should return the Airlock, 0xeb7C…0862.
2. Open the Airlock and read getAssetData(token). Note the poolInitializer and liquidityMigrator. The DopplerHookInitializer plus the NoOpMigrator is the combination described above.
3. Open the DopplerHookInitializer and read getState(token). A status of 2 means Locked. getBeneficiaries(token) lists who receives the pool's fees.
4. Back on the token, read vestedTotalAmount(), then vestingSchedules(0) for the cliff and duration in seconds (2,592,000 is 30 days; 31,536,000 is one year). vestingOf(address, 0) shows what a beneficiary has been allocated and released.
5. Finally, check the holder list. The token contract holding a balance of its own token is the unvested allocation. Large wallets beyond that are what holder distribution is about.

HoodLock's liquidity lock checker and token lock checker show what is locked on HoodLock for a token. A Doppler pool's launch liquidity is held by Doppler's contracts, not by HoodLock, so it won't appear there; anything a creator has locked or vested with HoodLock will.

Locking or vesting your allocation with HoodLock

If you launched through Doppler, the pool question is settled. The open questions are the balances Doppler leaves liquid, and those are what holders look at next.

• Tokens you hold now, such as a dev buy or vested tokens already released, can be locked until a date at /app/locks/tokens.
• Team or contributor tokens can be put on a schedule with a cliff at /app/vesting, each with its own beneficiary and proof page.
• Liquidity you add yourself is your own position. See the Liquidity Locker docs for which positions it accepts before relying on it for a hooked pool.

Pricing is listed on the fees page. Every lock and schedule gets a proof page that reads from the chain and opens without a wallet.

Common questions

Is liquidity locked on Doppler launches on Robinhood Chain?

For almost every launch, yes, and with no end date. Over 99% of Doppler launches on Robinhood Chain use the DopplerHookInitializer, which holds the launch liquidity as Uniswap V4 positions in its own name. Every launch we sampled was marked Locked and paired with the NoOpMigrator, so the only function that removes those positions can never run.

Does the Doppler hook use beforeRemoveLiquidity to block withdrawals?

No. The DopplerHookInitializer leaves beforeRemoveLiquidity switched off, and its address encodes that. The lock comes from ownership: Uniswap V4 keys every position to the contract that created it, so only the initializer can remove its positions, and its one removal path requires a status a locked launch never reaches.

Do Doppler launches migrate liquidity after the bonding curve?

Not on Robinhood Chain in practice. The Airlock has emitted exactly one Migrate event there, for a test token. Launches set up with the NoOpMigrator cannot migrate at all, because its migrate function always reverts, so liquidity stays in the original pool.

Are creator tokens locked on a Doppler launch?

Only if the launch reserved a vested allocation, and only until it vests. DopplerERC20V1 can vest up to 80% of supply, and a schedule may even vest instantly. Released tokens, tokens bought from the pool and fee income are ordinary balances that can be sold at any time.

Does Bankr use Doppler on Robinhood Chain?

Yes. Bankr launches on Robinhood Chain are created through Doppler's Airlock with the DopplerHookInitializer, and their metadata names Bankr as the launch provider. Recent ones vest 15% of supply to the creator over one year behind a 30-day cliff; the earliest, in July 2026, used two years.

Can I lock or vest Doppler tokens with HoodLock?

Yes. A Doppler token is a standard ERC-20 on Robinhood Chain, so tokens you hold can be locked until a date or vested to a beneficiary on HoodLock, with a public proof page for each.
