Tychi: terminal wallet for humans, MCP wallet for agents — keys local, Arbitrum onchain.
Tychi — self-custody wallet built for humans and AI agents.
Humans → tyi CLI (REPL)
Talk in plain English in your terminal. Check balances, send tokens, manage wallets — no dashboard, no browser extension. Keys encrypted in ~/.tyi on your machine.
Agents → @tychilabs/tyi-mcp
Plug into OpenClaw, Claude Desktop, Cursor, or any MCP host. Fast tools for onboard, create/import/switch wallet; tyi_chat for balance, sends, and policy-gated ops. Same keystore, different interface.
How the stack splits
- Local: keys, signing, policy caps, audit log
- Hosted brain: intent parsing, LLM routing, quotes — never sees your private keys
Live now: onboard, multi-wallet, balance, sends, npm packages, public GitHub (Apache-2.0).
Next on Arbitrum: UGF gas routing today → automation, trading, lending, borrowing.

We spent the buildathon turning Tychi from an idea into something you can actually run. We shipped two packages on npm: tyi for humans (terminal REPL — ask your balance or send in plain English) and tyi-mcp for agents in Cursor, Claude, or OpenClaw. Same wallet file on your machine; keys stay in ~/.tyi, brain handles intent, signing never leaves your laptop. On the agent side we focused on speed — direct MCP tools for onboard, create/import/switch wallet instead of forcing everything through a slow chat loop. Policy caps and local signing are in and working. We open-sourced the MCP repo on GitHub (Apache-2.0), published beta builds, recorded a product demo, and tested the full flow on Arbitrum with UGF gas routing. Next up on Arbitrum: automation, trading, lending, and borrowing so agents can do more than send — they can actually compound capital. We're building in public and want real feedback on what breaks.
Bootstrapped to date. Now raising pre-seed to scale infra, Go-to-Market, Arbitrum DeFi roadmap, and agent-wallet distribution.
