Deploy LP Mining Referral Tokens

In response to recent user inquiries about how to create a token with an LP pool that rewards users who are referred to add to the pool, CPBox has analyzed the contract code in the repository to help users understand the entire pool and contract content, while enabling them to deploy similar tokens to meet their specific needs.

  1. First, this is an ERC20 Token that supports basic token transfers and balance queries. We need to set the token's name, symbol, and decimal parameters during deployment.
  2. Transaction fee mechanism
    1. Buy tax rate and sell tax rate, each not exceeding 25% of the total
      1. Buy/Sell Tax: Each purchase will deduct the corresponding proportion of tokens and send them to the contract address. When the trigger threshold is reached, it will automatically sell and send to your marketing wallet address.
      2. Burn Tax: Each purchase will deduct the corresponding proportion of tokens and send them to the black hole address to achieve burning.
      3. Liquidity Tax: Each purchase will deduct the corresponding proportion of tokens and send them to the contract address. When the trigger threshold is reached, it will automatically add liquidity to make the pool thicker. The LP obtained from adding to the pool defaults to the marketing wallet.
  3. Supports whitelist mechanism, whitelist addresses can be exempted from fees
  4. Liquidity Mining
    1. Mining Supply Ratio: The proportion of tokens produced by mining out of the total token supply. For example, if the total token supply is 100,000,000 and mining produces 50,000,000, then this ratio should be 50%. When creating the contract, 50,000,000 tokens will directly enter the mining contract, and no one can withdraw them.
    2. Daily Mining Rewards: Fixed daily output of tokens, just enter the amount directly.
  5. Invitation Reward Mechanism
    1. Supports multi-level invitation reward system, can set different reward ratios for different levels:
      • Invitation Levels: How many sub-levels can there be, currently up to 16 levels can be set
      • First level amount, second level amount, third level amount, remaining level amount, the sum of all should be 100%

This is a quite complete token contract, especially suitable for:

  • Liquidity mining projects
  • Projects with invitation reward mechanisms
  • Projects requiring complex fee structures
  • Projects requiring airdrop functionality

The contract design is quite flexible, administrators can adjust the token's economic model through various parameters, including rates, reward mechanisms, etc. It also includes necessary security mechanisms to prevent abuse. We can use the contract provided by CPBox and directly import it into remix for deployment:

Liquidity Mining Code

Here I provide a set of parameters and explain how to modify them to suit your own parameters:

  • First stringParams parameter: ["CPBoxTestToken", "CPBLP"]
  • Second addressParams parameter:

["0x1234567890123456789012345678901234567890","0x0987654321098765432109876543210987654321","0x1111111111111111111111111111111111111111","0x2222222222222222222222222222222222222222"]

  • Third numberParams parameter: ["18","1000000000000000000","200","100","50","200","100","50","30","100000000000000000","100000000000000000","100000000000000000","10","50","30","10","2","10","3","1000000000000000"]
  • Fourth boolParams parameter: [true,true,true,true,true,true]
