DEX sniper bot: how to get first-block fills

#python #trading #crypto

I've been working on multi-chain dex trading bot (8 chains) for a while and wanted to share what I learned.

The problem

Trade on 8 blockchain networks from one bot. Supports Ethereum (Uniswap), Solana (Jupiter), BSC (PancakeSwap), Polygon (QuickSwap), Arbitrum (SushiSwap), Optimism (Velodrome), Avalanche (TraderJoe), and Cronos (VVS).

What I built

Here are the main features I ended up shipping:

8 blockchain networks
8 DEX integrations
Token sniping and trading
Gas optimization
Multi-wallet support
Web dashboard

Code sample

# Basic structure
class Bot:
    def __init__(self, config):
        self.config = config

    def run(self):
        while True:
            self.scan()
            self.execute()
