# How to Record DeFi and DEX Trades in a Journal

Decentralized exchange (DEX) and DeFi trades have costs and mechanics that centralized exchange journals are not built for. Here is how to adapt your journaling for on-chain trading.

## Unique Costs in DeFi Trading

**Gas fees:** Every transaction on Ethereum (and L2s) costs gas. A $50 gas fee on a $500 trade is 10% cost before any spread. Log gas costs separately.

**Slippage:** DEX trades are executed against liquidity pools, not order books. Large trades relative to pool depth cause slippage. Log expected vs actual execution price.

**MEV / Sandwich attacks:** Your swap can be front-run by MEV bots that insert transactions before and after yours to extract value. This appears as worse-than-expected execution. Log execution quality.

**Price impact:** On low-liquidity pools, a $5,000 swap might move price 2–3%. Log your price impact for every trade.

## What to Record for DEX Trades

```
Chain: Ethereum / Arbitrum / Base / Solana / etc.
Protocol: Uniswap / Curve / GMX / Jupiter / etc.
Pair: ETH/USDC / etc.
Direction: Buy token / Sell token
Entry price (expected): [price]
Execution price (actual): [price]
Slippage: [% difference]
Gas fee (USD equivalent): [amount]
Price impact: [%]
Total cost (gas + slippage): [amount]
Net entry price (after costs): [price]
Exit price: [price]
Net P&L (after all costs): [amount]
```

## Handling LP (Liquidity Provider) Positions

LP positions are different from directional trades. Track:
- Date entered LP
- Assets deposited and amounts
- Price range (for concentrated liquidity)
- Fees earned per day/week
- Impermanent loss vs fee income
- Net return when position closed

These are not standard journal trades — use notes or a separate spreadsheet alongside your journal.

## Summary

DeFi trading has hidden costs that can easily exceed 5–10% of a trade's value on smaller positions. Recording gas, slippage, and price impact gives you a true picture of your DeFi performance — including whether the strategy is actually profitable after all on-chain costs.
