+# Contract
+
+This document outlines the "soft contract" expected by the `CODEOWNERS` and maintainers
+of the `x/nft` module to follow and uphold. The agreed-upon members are expected
+to abide by the following:
+
+- Review and provide feedback on PRs that primarily impact or modify the `x/nft`
+module within 30 days.
+- Review and provide feedback on issues related to the `x/nft` module within 30
+days.
+- Maintain compatibility with the APIs, design philosophy, architecture and the
+broader set of tools (e.g. simulation) within the SDK.
+
+If the broader set of `CODEOWNERS` and maintainers of the SDK deem that the stated
+contract has been breached by a containing member of the `x/nft` module, that
+member may be removed with or without warning from the `CODEOWNERS`. If the entire
+set of owners and maintainers are deemed to break the contract, the `x/nft` module
+maybe removed with or without warning from the SDK.
