# V2 Dynamic staking Guide

This guide covers the V2 **DecubateStaking** contract — a unified staking contract supporting both ERC-20 token staking and NFT staking with rate-based rewards. If you are unsure which version you have, see the Staking Version Identification Guide.

***

### Prerequisites

* Your DecubateStaking contract address.
* A block explorer for your chain (e.g., Etherscan, BscScan).
* A wallet (e.g., MetaMask) connected to the correct network.

> Use the **"Read as Proxy"** and **"Write as Proxy"** tabs on the block explorer.

### Check Claim Fee
