 ### Backends
 
-There are multiple **blockchain backends** available. A backend is automatically initialized when its top-level package `backend/<name>` is imported.
-- **Ethereum.** The Ethereum backend is available at [perun-eth-backend](https://github.com/perun-network/perun-eth-backend/).
-- **Polkadot.** The Polkadot backend is available at [perun-polkadot-backend](https://github.com/perun-network/perun-polkadot-backend).
-- **Cosmos.** The Cosmos backend is available at [perun-cosmwasm-backend](https://github.com/hyperledger-labs/perun-cosmwasm-backend).
-- **Cardano.** The Cardano backend is available at [perun-cardano-backend](https://github.com/perun-network/perun-cardano-backend).
-- **NERVOS.** The NERVOS backend is available at [perun-ckb-backend](https://github.com/perun-network/perun-ckb-backend).

-- **Stellar.** The Stellar backend is available at [perun-stellar-backend](https://github.com/perun-network/perun-stellar-backend).
-- **Fabric.** The Hyperledger Fabric backend is available at [perun-fabric](https://github.com/perun-network/perun-fabric).
-- **SimBackend.** The SimBackend represents an ideal blockchain backend (`backend/sim`) implementation that can be used for testing.

+- ✅ **Supported** – stable and available.  
+- 🚧 **In development** – actively worked on, not fully stable.  
+- 🟡 **Single-chain** – supports only local (non-cross-chain) payment/state channels.  
+- 🧪 **Testing only** – simulation backend, no real blockchain. 
 
 **Logging and networking** capabilities can also be injected by the user.
 A default [logrus](https://github.com/sirupsen/logrus) implementation of the `log.Logger` interface can be set using `log/logrus.Set`.
