A Guide for DEX Newbies by #中心化与去中心化交易所

Step 1: Secure Infrastructure (Must Do!)

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

2. Gas Reserve: 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 unused authorizations

- Always refuse unlimited authorizations

Step 2: Avoiding Pitfalls in Practice

Pangolin Scam: Use [Token Sniffer] to check the contract: Is there liquidity locked/abandoned rights/blacklist features?

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

Frontend Interface Hijacking: Bookmark the DEX official website and disable random wallet signature domains

Gas War Loss: For non-urgent transactions, use [Flashbots RPC] to avoid frontrunning, set a Gas cap

Step 3: Efficient Trading Techniques

1. Slippage Control:

- Split large transactions into multiple smaller ones

- Use 1inch's model to aggregate the optimal path

2. Cost Optimization:

- Operate on L2

- Choose low-fee time periods

3. Monitoring Tools:

- [DeBank] to track asset gains and losses

- [Arkham] to track whale movements

The Symbiotic Future of CEX and DEX

Irreplaceable Value of CEX: Fiat channels, compliant derivatives, large liquidity;

The Innovative Significance of DEX: Censorship-resistant finance, passive LP income, contract composability;

CEX is becoming more like DEX, and 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 the private key, just like respecting fire."
