Configuration

Overview

Memez.gg is highly configurable to facilitate third party integrations and revenue sharing.

Integrators can configure the following parameters:

• Fees

• Migrator

• Public Key

During creation, the deployer can choose which configuration the pool will adhere to. E.g., user A could opt for the Memez configuration, while user B opts for Blast.fun configuration.

Integrators need to request our team to add their configuration.

Fees

Memez.fun has 3 fees:

public enum Fee has copy, drop, store {
    Value(u64, Distributor),
    Percentage(BPS, Distributor),
}

public struct FeePayload has copy, drop, store {
    value: u64,
    percentages: vector<u64>,
    recipients: vector<address>,
}

public struct Allocation<phantom T> has store {
    balance: Balance<T>,
    vesting_periods: vector<u64>,
    distributor: Distributor,
}

public struct MemezFees has copy, drop, store {
    creation: FeePayload,
    meme_swap: FeePayload,
    quote_swap: FeePayload,
    migration: FeePayload,
    allocation: FeePayload,
    vesting_periods: vector<u64>,
    dynamic_stake_holders: u64,
}

• Creation: Sui amount charged to create a meme coin + pool.

• MemeSwap: % charged on every sell or buy in meme coin.

• QuoteSwap: % charged on every sell or buy in quote coin.

• Migration: Meme coin % to be used for DEX liquidity after migration.

• Allocation: Meme coin % allocated for the stake holders.

• Vesting Period: The duration of the linear vesting for the allocation.

• Dynamic Stake Holders: The number of stake holders the pool requires during creation.

The integrator can decide the total amount of each fee and the number of recipients per fee. It is possible to charge no fees at all and different percentages and recipients per fee. The swap and migration fee include the deployer as one of the recipients if chosen by the integrator.

For example an integrator can decide to have:

• Creation Fee of 2 Sui:

  • 20% to X

  • 60% to Y

  • 20% to Z

• No Swap fee

• 10 % Migration quote fee

  • 50% to A

  • 50% to B

• 5% Meme coin allocation to stake holders

Pump Configuration

At pool creation the sender configures the values below.

public struct PumpConfig has copy, drop, store {
    burn_tax: u64,
    virtual_liquidity: u64,
    target_quote_liquidity: u64,
    liquidity_provision: BPS,
    quote_type: TypeName,
}

• Burn Tax: The burner tax explained above

• Virtual Liquidity: The floor price of the Meme coin as determined by a virtual Sui amount

• Target Sui Liquidity: The amount of Sui the pool must collect to migrate. It can be seen as a target price.

• Liquidity Provision: Percentage of Meme coin to be used to seed the liquidity pool during migration.

• Quote Type: The type of the quote Coin<Quote>.

Burn Tax

The Auction and Pump strategies have a burn tax built-in. This is a dynamic tax that increases linearly as the amount of Sui in the pool increases. It can range from 0 to 30%. This tax is only applied when one sells Meme coins for Sui. The coins are actually burnt (not sent to 0x0) as Memez uses the IPX Coin Standard for all meme coins. This is to prevent king of the hill griefing tactics. As the tax is quite high when it is close to bonding.

public struct MemezBurner has copy, drop, store {
    fee: BPS,
    target_liquidity: u64,
}

• Fee: A percentage in bps to determine how much amount to burn.

• Target Liquidity: The liquidity required t migrate the pool.

Example

Burner tar Tax Formula

progress = current_liquidity / target_liquidity

tax = burner_tax * progress Example

Let's assume we have a pool using the Pump strategy with a Sui Target Amount of 1_000 Sui and a Burner tax of 20% of 2_000 basis points.

t0: The pool has 0 Sui - burn tax would be 0%

Math:

progress = 0 / 1_000 ⇒ 0

20% * 0 / 1000 ⇒ 0%

t1: The pool has 800 Sui - burn tax would be 16%

Math:

progress = 800 / 1_000 ⇒ 80%

20% * 80% ⇒ 16%
