# Instant Launch (/docs/liquidity/liquidity-launchpad/concepts/instant-launch)

Learn how Instant Launch creates a Uniswap v4 pool with the entire token supply as a single-sided position.

## How It Works
[InstantLaunchStrategy](https://github.com/Uniswap/liquidity-launcher/blob/main/src/strategies/InstantLaunchStrategy.sol) is called via `LiquidityLauncher.distributeToken()` like other strategies. In a single transaction, it:

1. pulls the full token supply from [Liquidity Launcher](https://github.com/Uniswap/liquidity-launcher/blob/main/src/LiquidityLauncher.sol) into the strategy
2. initializes a hookless Uniswap v4 pool pairing native ETH with the token, using the strategy's fixed parameters
3. mints a single position holding the entire token supply as a single-sided position
4. if a [BeneficiaryVault](https://github.com/Uniswap/liquidity-launcher/blob/main/src/periphery/BeneficiaryVault.sol) address was provided during the deployment of that Instant Launch strategy contract, it registers the fee beneficiary provided via the `InstantLaunchConfig` struct inside the `configData`.
5. transfers the position to the [FeeSplitter](https://github.com/Uniswap/liquidity-launcher/blob/main/src/periphery/FeeSplitter.sol), which holds it permanently and allows only to collect fees or to increase the position's size.

The pool allows the token to be traded instantly after the launch.

## Fixed Token and Launch Parameters
The strategy calls `token.totalSupply()` and `token.decimals()` to verify they match the required launch parameters, before proceeding to create a pool. All pool parameters are fixed during the strategy's deployment to ensure every launch from a specific deployment of Instant Launch shares these parameters.

| Parameter      | Value                               |
| -------------- | ----------------------------------- |
| Total supply   | 1,000,000,000 (18 decimals)         |
| Pool           | native ETH / token, no hook         |
| LP fee         | 0.25% (`2500`)                      |
| Tick spacing   | 25                                  |
| Position range | `MIN_LAUNCH_TICK` to `initialTick`  |
| `initialTick`  | fixed at deployment of the strategy |

## LP Fees
LP fees accrue to the launch position, which the `FeeSplitter` owns and cannot transfer out. Collection is permissionless, and collected amounts are split by immutable shares set at deployment, with separate basis points for the native and the token side.

* **[UERC20BeneficiaryVault](https://github.com/Uniswap/liquidity-launcher/blob/main/src/periphery/UERC20BeneficiaryVault.sol)** holds the creator's share. It mints a transferable ERC-721 at registration; only its holder can claim. Registration does not have to happen at launch: a claim on an unregistered position registers it, provided the caller matches the token's graffiti.
* **[CompoundingClaimRecipient](https://github.com/Uniswap/liquidity-launcher/blob/main/src/periphery/CompoundingClaimRecipient.sol)** allows any caller to compound collected swap fees back into the locked position, via a contract implementing [IClaimExecutor](https://github.com/Uniswap/liquidity-launcher/blob/main/src/interfaces/IClaimExecutor.sol). See [Collect and Compound Fees](/docs/liquidity/liquidity-launchpad/guides/collect-and-compound-fees).
* **[BuybackAndBurnClaimRecipient](https://github.com/Uniswap/liquidity-launcher/blob/main/src/periphery/BuybackAndBurnClaimRecipient.sol)** accumulates the fee share routed to it and releases it to any caller who burns a fixed amount of the token. See [Buyback and Burn](/docs/liquidity/liquidity-launchpad/guides/buyback-and-burn).

## Compared to CCA
|                   | Instant Launch            | CCA                                      |
| ----------------- | ------------------------- | ---------------------------------------- |
| Price             | fixed at deployment       | discovered by the auction                |
| Capital to launch | token only                | the currency raised by the auction       |
| Supply            | all of it, into the pool  | split between auction and LP             |
| Positions         | exactly one, single-sided | weighted plan plus a full-range fallback |
