# Bitlayer - Vault

Before getting started with the Bitlayer Vault, ensure you have the following ready:

* **Ethereum Wallet**: A Web3-compatible wallet like MetaMask is required to store funds and interact with the EigenFi dApps.
* **Gas Fees**: Your wallet must have enough ETH to cover transaction costs, including deposits, withdrawals, and smart contract interactions. Gas fees vary based on network activity, so it's best to keep some extra Native tokens available.

**Bitlayer Testnet - Faucet**
