SECURITY ALERT for DXSale Presale Vulnerability

We analyzed the DXSale presale smart contract and found a critical vulnerability that puts investors' funds at risk.

WHAT IS THE BUG?

Every DXSale presale has a softcap with a minimum fundraising threshold. If the softcap is not reached, investors are entitled to a full refund.

However, the presale contract contains a hidden function called forceSucceed() that allows the project team to mark the presale as "successful" regardless of how much was actually raised; completely bypassing the softcap protection.

HOW IT WORKS:
1. Presale runs below softcap
2. Team calls forceSucceed() via a raw transaction (selector: 0x422099b2)
3. Presale is marked as succeeded
4. All refunds are permanently blocked
5. Team finalizes and withdraws the collected funds
6. Investors receive fewer tokens than expected at a recalculated rate

WHY INVESTORS CAN'T SEE IT
DXSale presale contracts are NOT verified on BscScan. Investors cannot read the source code or know that forceSucceed() exists.
The team however can execute it in under 30 seconds through MetaMask using a simple raw transaction.

REAL CASE STUDY
Contract: 0x53279574B490b8A5edcAA1693F6A7Fe44ADB7b1F (BSC) (nothing against the team of this project i only use them as example)
Softcap: 2 BNB and Hardcap: 4 BNB
Raised: 2.07 BNB
Status: Concluded normally

This presale ended legitimately but the vulnerability was present and investors had no way to know the risk they were taking.

HOW TO PROTECT YOURSELF
Only invest in presales with verified contracts on BscScan
Before contributing, check that the contract has no admin override functions
Avoid presales where the source code is hidden
Ask the team to verify the contract before investing

THE FIX
DXSale should either remove forceSucceed() entirely or add a mandatory check:

require(totalRaised >= softcap, "Softcap not reached");

Presale success should be determined automatically by on-chain data only but never by a team-controlled function.

This finding was identified through smart contract bytecode analysis as part of a responsible disclosure audit. No funds were exploited. Our goal is to educate investors and push platforms to build safer tools.

Pump.fun Migration Sniper Bot

The Pump.fun Migration Sniper Bot is an automated trading bot designed to detect and buy tokens at the exact moment they migrate from Pump.fun to PumpSwap, leveraging the speed of the Solana network and Geyser + Jito infrastructure to achieve ultra-fast transaction execution.

The bot is built for advanced traders and DeFi operators who want to automate migration sniping strategies, with a fully customizable configuration system and an integrated backtesting engine to optimize performance.

How It Works
The bot monitors the Solana blockchain in real time using Geyser gRPC, detecting Pump.fun token migrations to PumpSwap as soon as they occur.

When a migration is detected, the bot:
1 - Analyzes the token’s liquidity parameters.
2 - Checks filters such as blacklist and liquidity thresholds.
3 - Immediately submits a buy transaction.
4 - Uses Priority Fees and Jito Tips to maximize transaction inclusion speed.
5 - Automatically manages the position using take profits, stop loss, and trailing stop strategies.

The bot includes a fully customizable configuration system.

Network Connection:
•RPC Endpoint
Custom RPC endpoint used to interact with the Solana network.
•Geyser gRPC URL
Geyser endpoint used to receive real-time blockchain events.
•Geyser Token
Authentication token required to access the Geyser stream.

Buy Parameters:
•Buy Amount (SOL)
Amount of SOL used for each purchase.
•Slippage
Maximum allowed slippage during the swap execution.
•Priority Fee (micro-lamports)
Additional fee used to increase transaction priority on the Solana network.
•Jito Tip (SOL)
Tip sent to Jito validators to further improve block inclusion speed.

Position Management:
The bot integrates an advanced exit strategy system:
•3 Take Profit Levels
•Take Profit 1
•Take Profit 2
•Take Profit 3
•Stop Loss
Automatic protection to limit downside risk.
•Trailing Stop
A dynamic stop that follows price increases to maximize profits during pumps.

Risk Management:
•Max Concurrent Snipes
Maximum number of tokens that can be sniped simultaneously.
•Min Liquidity
Minimum liquidity required to trigger a buy.
•Max Liquidity
Maximum liquidity threshold to filter out overly large projects.
•Blacklist
Ability to exclude specific wallets, developers, or suspicious tokens.

Backtesting System:
The bot includes an integrated backtesting engine that allows users to test strategies on historical migration data.

Strategies can be simulated using a customizable dataset of migrated tokens, ranging from:
•10 tokens
•up to 1000 migrated tokens

This allows users to:
•Evaluate strategy performance
•Optimize take profit and stop loss parameters
•Identify the most profitable configuration before deploying live

Objective:
The goal of this bot is to provide a professional framework for Pump.fun migration sniping, combining:
•ultra-fast execution
•advanced risk management
•strategy optimization through backtesting
