Olas

This bounty is recommended for hackers with at least 2 years of Python experience who want to build an autonomous agent.

Creating an agent from scratch can take time, but you don't have to start from zero thanks to the composability of the Olas Stack. Valory has prepared a template agent that does basic transfers on Celo using an LLM mech tool to create the transaction. You can easily take this agent and customize it how you want.

Get started:

• How to extend the Celo transfer agent
  • Video
  • Guide
• Inspiration:
  • An agent that pays invoices monthly
  • A prepares a payment plan and executes it
