A Guide for DEX Beginners from #中心化与去中心化交易所

Step 1: Security Infrastructure (Must Do!)

1. Isolated Wallet: Create a dedicated DEX trading wallet (do not mix with main assets), recommended MetaMask

2. Gas Reserves: Reserve Gas fees on the target network before cross-chain (e.g., ETH for Arbitrum, SOL for Solana)

3. Authorization Management:

- Use [Revoke.cash] to regularly clean up idle authorizations

- Always refuse unlimited authorizations

Step 2: Practical Anti-Scam Measures

Pi Xiu Ponzi Scheme: Use [Token Sniffer] to check the contract: is there a locked pool/abandonment/blacklist function?

Fake Token Phishing: Only trade tokens listed on CoinGecko, paste contract address and [compare with the official website]

Front-End Interface Hijacking: Bookmark the DEX official website, disable random domain signatures for wallet transactions

Gas War Losses: Use [Flashbots RPC] to avoid frontrunning for non-urgent transactions, set a Gas limit

Step 3: Efficient Trading Techniques

1. Slippage Control:

- Split large transactions into multiple smaller ones

- Use 1inch to aggregate the optimal path

2. Cost Optimization:

- Operate on L2

- Choose low fee time periods

3. Monitoring Tools:

- Use [DeBank] to track asset gains and losses

- Use [Arkham] to track whale movements

The Symbiotic Future of CEX and DEX

The irreplaceable value of CEX: fiat gateways, compliant derivatives, large liquidity;

The innovative significance of DEX: censorship-resistant finance, passive LP earnings, contract composability;

CEX is becoming more like DEX, DEX is becoming more like CEX, hybrid exchanges will be the next generation of infrastructure.

“Start with CEX, explore with DEX, safeguard with hardware wallets.

— Always respect private keys, just as you respect fire.”
