Contracts maintain an agreement between two citizens.
A contract is an agreement between two citizens created at a Contract Board. The agreement can have any number of clauses, and specify combinations of work to be performed and compensation to be paid. It is posted by the client citizen, and can be accepted by any valid citizen asynchronously.
Examples of contract include: - Create a road between two designated points. - Loan money between two parties with a given interest rate and due date. - Build a room of given requirements at a specific location. - Custom requirements described in text, and accepted/rejected by the client upon completion.
🌱 Local AI
The descriptive prose on this wiki is written by a large language model — but it runs entirely on local, self-hosted hardware: a Gemma 4 E4B model on a single NVIDIA RTX 4070 in a home Unraid server.
Nothing you read here was generated by a commercial cloud API. The game data itself is pulled live from the Eco server; the AI only fills in flavor and gap text. Like any web server, this one keeps its own request log — including visitors' IP addresses — purely to run and improve the site; it is never sold or handed to a third party.
This wiki is one face of a larger Eco mod: Solomon, an in-world AI steward that runs the server's economy, posts help contracts, keeps a store, and answers players. The wiki reads the same live game registries and tools Solomon does — so the numbers stay true to the running world. Read more about the project →
