MBURN Features:
- On Launch
- Buy tax:
- 4% Burn (tokens instantly deleted from existence+supply)
- 2% Marketing
- 1% Buyback & Burn
- Sell tax:
- 4% Burn (tokens instantly deleted from existence+supply)
- 2% Marketing
- 1% Buyback & Burn
- 180 Second Sell Delay Timer (wallets cannot sell for 180 seconds after making any transaction). Anti-whale & bot-flip function.
- 15%/25% max Buy/Sell tax restriction in functions
- Can renounce individual functions if needed in future: Delay Timer, Fee Functions, Max Update Functions, Market Maker Pair Changes, Wallet Changes, and Exclude Include Functions
