Set-up wallet for xDai

Setting up wallet for xDai (mandatory for those who want to bridge from Binance Smart chain to Polygon)
For a quick method, visit Chainlist to quickly add to MetaMask. You may still need to add Blockscout (xDai)
1) Open Metamask, and select "Custom RPC" from the Network Dropdown.
2) In the "Custom RPC" Settings, add in the xDai network details and click Save:
Note: Chain ID 0x64 is the hexadecimal equivalent of 100, which is the xDai chain ID. MetaMask recently updated the ChainID to be a required field. When you update, you may need to reenter the Chain ID: 100, and it will be converted to a hexadecimal: 0x64.
If you are having issues, try entering 100 for Chain ID and resaving the configuration.
If you'd prefer not to make these changes, Nifty Wallet provides a built-in xDai RPC.
Once you add the xDai network, you will need xDai to pay for transactions. See Getting xDai for more information.
