+## Set Network Chain Context {#set-chain-context}
+
+To change the chain context of a network, use
+`network set-chain-context <name> <chain-context>`.
+
+:::caution
+
+Chain contexts represent a root of trust in the network, so before changing them
+for production networks make sure you have verified them against a trusted
+source like the official Oasis documentation.
