+FrostFS contract is a contract deployed in FrostFS mainchain.
+
+FrostFS contract is an entry point to FrostFS users. This contract stores all FrostFS
+related GAS, registers new Inner Ring candidates and produces notifications
+to control the sidechain.
+
+While mainchain committee controls the list of Alphabet nodes in native
+RoleManagement contract, FrostFS can't change more than 1\3 keys at a time.
+FrostFS contract contains the actual list of Alphabet nodes in the sidechain.
+
+Network configuration is also stored in FrostFS contract. All changes in
+configuration are mirrored in the sidechain with notifications.
+
+# Contract notifications

+GAS to the FrostFS contract address. The same amount of FROSTFS token will be
