How PLUMBERS works

Overview

A DeFi system centred on liquidity providers

PLUMBERS joins four related parts in one public Ethereum interface. The PLUMBERS token has a fixed supply. Its main market is the PLUMBERS/WETH Uniswap V2 pair. Holders of that pair's LP token can stake it in MasterPlumber for a finite stream of PLUMBERS rewards. The Farm Factory lets anyone create a separate fixed-supply token, TOKEN/WETH pair, and LP farm with creator-selected terms.

The website reads contracts, balances, reserves, schedules, and Factory records from Ethereum through several public RPC endpoints. A wallet is needed only when a user chooses to submit a transaction. Browsing farms, charts, terms, addresses, and documentation does not require a connected wallet.

Core PLUMBERS

Fixed supply, one market, one farm

The PLUMBERS supply is fixed at one trillion tokens. Half was assigned to the historical airdrop and half to the farm inventory. There is no later mint that can expand the supply. The core farming job accepts only PLUMBERS/WETH Uniswap V2 LP tokens.

Rewards are scheduled by Ethereum block. The opening bonus and normal schedule are fixed in the deployed contracts. When nobody is staked, rewards scheduled for that interval are not carried forward. This keeps the total inventory and timing bounded instead of extending the programme whenever participation is low.

Participant workflow

From token to LP position

1. 01

   Hold PLUMBERS and ETH

   Eligible wallets can claim from the published airdrop. Other users can swap through the PLUMBERS/WETH market.

2. 02

   Add liquidity

   Pair PLUMBERS with ETH through Uniswap V2. The interface calculates the matching side from current reserves.

3. 03

   Receive LP tokens

   The pair mints UNI-V2 LP tokens that represent the wallet's proportional share of both pool assets and accrued pool fees.

4. 04

   Stake LP tokens

   Deposit those LP tokens into MasterPlumber to participate in the fixed PLUMBERS reward schedule.

5. 05

   Harvest, compound, or exit

   Harvest sends rewards to the wallet. Compound pairs selected rewards with fresh ETH and stakes the new LP. Users can unstake and remove their ordinary liquidity.

Liquidity strategy

Why wider LP participation helps

A token market works better when it has useful depth and more than one active liquidity provider. Adding paired assets increases the pool's reserves. Larger reserves generally mean an ordinary trade changes the pool ratio less than the same trade would in a thinner pool. Every LP token holder also owns a proportional claim on the pool, including the trading fees retained in its reserves.

Staking LP tokens is a separate action. It does not add assets to the Uniswap pair, because the liquidity was already supplied when the LP token was minted. Staking places that existing LP position inside the reward contract. As more independent LP holders stake, a larger portion of the pool's ownership participates in the same finite emissions and monitors the same market.

More stake also means the fixed reward flow is divided across more LP tokens. The displayed reward rate can fall as total stake rises. That is not a defect in the accounting. It is the direct result of sharing a bounded reward stream among a broader base of participating liquidity. Reward rates are estimates, not promised returns.

Permissionless creation

What the Farm Factory creates

The PLUMBERS Farm Factory lets a creator make a complete token and LP farming setup in one Ethereum transaction. Each successful creation produces four public results:

• A token with exactly one trillion units, minted once.
• The canonical TOKEN/WETH Uniswap V2 pair for that token.
• An isolated LP farm funded with its complete reward inventory.
• A permanent Factory record containing the creator, contracts, allocations, schedule, and routing amounts.

The creator decides how the one-trillion supply is split between opening liquidity, the farm inventory, and the creator wallet. The interface keeps those values balanced to exactly one trillion. The creator also selects the start delay, duration, creator reward share, and optional metadata or image link.

Initial liquidity is optional. When a creator opens with liquidity, the genesis LP tokens are minted directly to the zero address and cannot be withdrawn. When a creator opens without liquidity, they must receive some token supply, and the first later LP provider chooses the opening ratio and owns the LP tokens they receive.

Factory connection

How Factory activity connects back to PLUMBERS/WETH

The Factory has a configurable creation fee for future farms. At ordinary whole-wei values, 90% of that fee is wrapped as WETH and sent to the PLUMBERS/WETH pair, while 10% goes to the fixed team recipient. This fee is separate from any ETH a creator chooses to use for their child token's opening liquidity.

Swaps made through the official Farm Factory interface use Factory swap functions with a 1% interface fee. That fee is routed as WETH to the PLUMBERS/WETH pair. The normal 0.30% Uniswap V2 pool fee also applies to the child pair. A direct trade through Uniswap does not use the Factory interface function and therefore does not pay the separate Factory fee.

Routed WETH is sent to the pair and its reserves are updated. The Factory does not mint a new LP position for itself, and the routed WETH is not held in a team wallet. Existing PLUMBERS/WETH LP tokens continue to represent proportional shares of the pool reserves.

Verification, estimates, and risk

The interfaces expose contract addresses, wallet addresses, pair addresses, allocation terms, and block schedules so users can compare what the page displays with Ethereum. Farm Factory records are read directly from the Factory contract, while prices and LP values are derived from current pair reserves and public market data.

• Token and ETH prices can move quickly, especially in shallow pools.
• Liquidity providers can experience impermanent loss as the pool ratio changes.
• APY, APR, USD value, and time displays are estimates based on changing inputs.
• Ethereum transactions require gas and cannot be reversed after confirmation.
• Public RPC and chart services can be delayed or unavailable without changing the underlying contracts.
• Testing reduces known implementation errors but is not a promise that every contract or market outcome is risk-free.

Verify the URL, network, contract address, transaction value, and wallet prompt before signing. PLUMBERS does not guarantee profit, liquidity, price stability, or a particular reward rate.

Every child farm page also shows its token, TOKEN/WETH pair, farm, creator, and fixed recipient addresses with copy buttons and explorer links. Use the live directory to open a child farm.
