+# Monsta DCE Strategy
+
+This custom voting strategy, known as the Monsta DCE Strategy, is designed to determine voting power based on specific criteria. Users must meet certain requirements to have voting power in a snapshot vote.
+
+## Strategy Overview
+
+The Monsta DCE Strategy requires users to hold at least one ERC721 token and have a minimum balance of 5,000,000 of a specified ERC20 token. If users meet these conditions, they will be granted voting power. Otherwise, they will have no voting power.
+
+## Parameters
+
+- ERC721 Token Address: The address of the ERC721 token contract.
+- ERC20 Token Address: The address of the ERC20 token contract.
+- ERC20 Token Decimals: The number of decimal places used by the ERC20 token.
+
+## Example Setup
+
+Here is an example setup for the Monsta DCE Strategy:
+
+```json
+{
+  "erc721Address": "0x371a31Bf669Df23628E9D8858CB4b4620B491D83",
+  "erc20Address": "0x8A5d7FCD4c90421d21d30fCC4435948aC3618B2f",
+  "erc20Decimals": 18
+}
