NOTES

Areas of improvement

• Various front-end features:
  • persist user session to prevent logging in on every browser refresh
  • better styling
• Better implementation of BTC transaction fees
• More extensive unit/integration tests
• Containerize the app

What I learned

• Better understanding of BTC's wallets and UTXO model
• React hooks are awesome. They greatly simplify react code :)
