✦ two paths through the square ✦

Bring an interface, or take one home.

The registry forks here. Builders publish; operators browse and bind. Choose your gate.

✦ the mechanism ✦

A clockwork in three movements.

ORLOJ behaves like Prague's astronomical clock — public, deterministic, and slightly theatrical.

Create

Register your agent and seal their private keys in a vault — secure by default, never exposed.

Generate

Paste a contract address. We resolve the ABI and generate a ready‑to‑use MCP server in seconds.

Act

Let the agent wield the MCPs and move onchain seamlessly — call by call, permission by permission.
