+# EVM Contract Helpers
+
+This pallet extends pallet-evm contracts with several new functions.
+
+## Overview
+
+Evm contract helpers pallet provides ability to
+
+- Tracking and getting of user, which deployed contract
+- Sponsoring EVM contract calls (Make transaction calls to be free for users, instead making them being paid from contract address)
+- Allowlist access mode
+
+As most of those functions are intented to be consumed by ethereum users, only API provided by this pallet is [ContractHelpers magic contract](./src/stubs/ContractHelpers.sol)
