Each data command (track, portfolio, alert, etc.) works in two modes:
- With arguments: Records the input with a timestamp into its dedicated log file
- Without arguments: Displays the 20 most recent entries from that category
Data Storage
All data is stored locally in plain-text log files:
- Location:
~/.local/share/crypto-defi/
- Format: Each entry is saved as
YYYY-MM-DD HH:MM|<value> in per-category .log files
- History: All operations are additionally logged to
history.log with timestamps
- Stats: The
stats command aggregates entry counts and disk usage across all categories
- No cloud sync — everything stays on your machine, no API keys needed
Requirements
- Bash 4.0+ (uses
set -euo pipefail)
- Standard Unix utilities:
date, wc, du, head, tail, grep, basename, cat
- No external dependencies, no API keys, no network access required
- Works on Linux and macOS
When to Use
- DeFi position tracking — Record yield farming positions, staking entries, and liquidity pool allocations with timestamps for historical review
- Portfolio management — Log portfolio snapshots, token balances, and allocation changes to maintain a running record of your holdings
- Whale activity monitoring — Use
whale-watch to record large transaction observations and spot market-moving activity patterns
- Gas fee tracking — Log gas fee observations over time to identify optimal transaction windows and track network congestion trends
- Multi-protocol comparison — Use
compare and analyze to record side-by-side protocol evaluations and store your analysis notes
