The Shiden Network (SDN) is a utility token that serves several purposes within the Shiden ecosystem. Its primary functions include:

• Staking for Consensus: SDN tokens are used for staking to ensure the network's consensus mechanism.
• Rewards for Validators and Nominators: SDN tokens are distributed as rewards to validators and nominators for their participation in the network.
• Commission Payment: SDN tokens are used to pay commissions within the network.
• dApps Rewards System: SDN tokens are used to incentivize the development and use of decentralized applications (dApps) on the network. Token holders can stake their SDN tokens to support their preferred dApps, earning rewards in the process. This system encourages the creation of high-quality dApps and fosters a thriving ecosystem.

These functions enable the Shiden Network to operate efficiently and promote the growth of its decentralized application layer on the Kusama Network.

To store Shiden Network (SDN) tokens, you have several options:

1. Hardware Wallets: Ledger and Trezor are highly recommended for their security. You can connect your Ledger device to Ledger Live and find Shiden EVM (SDN) in the app to manage your tokens.

2. Software Wallets: Klever offers a secure crypto wallet with various payment methods to buy SDN tokens. This wallet provides a user-friendly interface to manage your SDN holdings.

3. Metamask: You can also use Metamask, but transferring SDN tokens between Substrate and Metamask requires converting addresses manually. There is a proposal to create a web interface to simplify this process.

4. Exchange Wallets: After purchasing SDN on an exchange, you can store it in the exchange's wallet. However, it is recommended to transfer your tokens to a hardware or software wallet for added security.

Remember to always prioritize the security of your tokens by choosing a reputable wallet and following best practices for storing cryptocurrencies.
