# xDai

The **xDai sidechain** is a stable payments blockchain designed for fast and inexpensive stable transactions. **xDai** is used for transactions, payments and fees, and **STAKE** is used to support Proof-of-Stake consensus.

See the [xDai documentation](https://www.xdaichain.com/) for more details.

## Connecting via MetaMask

See [this guide](https://www.xdaichain.com/for-users/wallets/metamask/metamask-setup) from the xDai documentation to connect your [MetaMask](https://metamask.io/) extension to the xDai chain.

**Alternative RPCs:**

## xDai Faucet

For anyone interested in experimenting with xDai before bridging tokens from the Ethereum mainnet, you can use the xDai faucet to claim 0.01 xDai (\~ 1 cent) for free, which is enough to execute a few transactions on xDai. Anyone can top-up the xDai faucet balance.

## Bridging Tokens from Ethereum

To convert DAI on the Ethereum network to xDai that lives on the xDai network use the [dai-bridge](https://dai-bridge.poa.network/).

To convert ERC20 tokens on the Ethereum network to ERC20 tokens on the xDai network use the [omnibridge](https://xdai-omnibridge.web.app/).

## Other Info

Ensure that no matter what MetaMask sets your gas cost to, that you always set it to 1. xDai gas cost is always 1 Gwei, paying less than this it's unlikely your transaction will be accepted, paying more than this will waste xDai. The gas limit should typically be left as it is.

The xDai [Block Explorer](https://blockscout.com/poa/xdai), similar to Etherscan, can be used to see transactions and accounts.
