+
+## Summary
+
+Encointer is a system chain on Kusama since Jan 2022 and has been developed and maintained by the Encointer association. This RFC proposes to treat Encointer like any other system chain and include it in the fellowship repo with [this PR](https://github.com/polkadot-fellows/runtimes/pull/17)
+
+## Motivation
+
+Encointer does not seek to be in control of its runtime repository. As a decentralized system, the fellowship has a more suitable structure to maintain a system chain runtime repo than the Encointer association does.
+
+Also, Encointer aims to update its runtime in batches with other system chains in order to have consistency for interoperability across system chains. 
+
+## Stakeholders
+
+* Fellowship: streamlined reviews of system chain runtime upgrades
+* Kusama Network: all system chains in one place
+* Encointer Association: Further decentralization of the Encointer Network necessities like devops.
+* Encointer devs: May be eligible for fellowship membership because of their contributions to the encointer runtime - being a system chain. 
+
+## Explanation
+
+There are no details to elaborate on. It's just about the location of our runtime code. 
+[Our PR](https://github.com/polkadot-fellows/runtimes/pull/17) has all details.
+
+Noteworthy: All Encointer-specific pallets will still be located in encointer's repo for the time being: https://github.com/encointer/pallets 
+
+## Drawbacks
+
+Other than all other system chains, development and maintenance of the Encointer Network is mainly financed by the KSM Treasury and possibly the DOT Treasury in the future. Encointer is dedicated to maintaining its network and runtime code for as long as possible, but there is a dependency on funding which is not in the hands of the fellowship. The only risk in the context of funding, however, is that the Encointer runtime will see less frequent updates if there's less funding. 
+
+## Testing, Security, and Privacy
+
+No changes to the existing system are proposed. Only changes to how maintenance is organized
+
+## Performance, Ergonomics, and Compatibility
+
+No changes
