For this SBC 2018, I'll build Facebook Messenger chatbot hot wallets.
Features for this round
1. Use chat conversation to query account data from horizon.
2. Use web view to let user sign tx directly with horizon.
3. Keep only encrypted public key with user defined password
4. Link user with Stellar public key so user can send XLM by mention @ USERNAME
5. Notify when account balance change.
