+# Skale-proxy
+
+skale-proxy is a public service that provides proxied and load-balanced JSON-RPC endpoints for SKL chains.
+
+It is based on Nginx reverse proxy that receives SKALE chain names and IP addresses of SKL nodes from SKALE manager. 
+
+# Endpoints
+
+For SKALE mainnet the endpoints that proxy provides are in the form of 
+
+http://proxy.skale.network/mainnet/CHAIN_NAME
+
+or
+
+https://proxy.skale.network/mainnet/CHAIN_NAME
+
+For SKL testnet the endpoints that proxy provides are in the form of 
+
+http://proxy.skale.network/testnet/CHAIN_NAME
