Why Ottie

Built for irreversible, adversarial environments

General-purpose agents assume actions are reversible and networks are reliable. None of this holds on public blockchains.

🛑

Irreversible Transactions

A bad email can be unsent. A bad transaction is permanent. Every action is treated as if real money is at stake — because it is.

🛡️

Adversarial Environment

Constrained blast radius, prompt-injection guard, and ClawWall DLP. The agent cannot access email, files, or browser — only blockchain.

🔄

Protocol Evolution

DeFi protocols change weekly. Self-evolving skills adapt to upgrades automatically, keeping the agent current without manual updates.

Features

Everything you need, nothing you don't

Single Go binary. Zero dependencies. Sub-second startup.
