Indie Chains is a platform that enables approved builders to trade useful mentions, reviews, and resource placements through context-first collaboration requests. It starts with the user's domain, where they create an account after their site is found. The platform allows users to suggest mentions, reviews, directories, or resource pages where another builder actually fits, and request collaborations from approved sites with context first. Every submitted site is checked before it can participate in the request network, and the network is built for useful placements, not bulk swaps or generic lists.
