## What it does

PumpClaw connects agents to a token factory on the Base blockchain. It deploys ERC-20 contracts alongside Uniswap V4 pools. Generating the token requires zero ETH upfront, and the pool liquidity remains permanently locked in the smart contract.

Trading pairs use native ETH to avoid wrapping overhead into WETH. Default settings apply a 1 billion token supply and an initial 2 ETH FDV, though both figures accept custom numbers. Trading carries a 1% swap fee, where 80% routes directly to the creator wallet while 20% remains with the protocol.

Signing transactions on Base requires passing your wallet credentials through the `BASE_PRIVATE_KEY` environment variable.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `BASE_PRIVATE_KEY`, `BASE_RPC_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

## When to use it
- deploy ERC-20 tokens on Base without creation ETH costs
- set up Uniswap V4 liquidity pools with native ETH
- collect 80% of swap fees into an agent wallet
- monitor pending trading fees and claim them

## Example prompts
- Deploy a token named ClawToken with symbol CLAW and 2 ETH FDV on Base
- Check pending creator fees for token address 0x3A9c65f4510de85F1843145d637ae895a2Fe04BE
