The Problem

Building an agent that trades crypto is a nightmare

Wallet key management. Transaction signing. RPC failures. Nonce tracking. Every agent builder hits the same wall — you spend 80% of your time on infra and 20% on strategy.

OpenFinance abstracts all of it. Your agent sends HTTP requests. We handle the rest.
