Crypto deserves a purpose-built agent. One that speaks Ethereum natively. One that treats security as a structural property, not an afterthought. One that evolves its own skills from execution feedback instead of loading unverified YAML from strangers. Ottie is that agent(https://github.com/jiayaoqijia/ottie): a single Go binary with 22 blockchain-native skills, multi-agent swarms, and 13 messaging channels compiled into one deployment artifact.
