Step 1 - Make sure your MetaMask wallet is setup on ETH Mainnet
Step 2 - Connect to Omnibridge and then connect the wallet you are willing to interact with
Step 3 - Select the token you are willing to send from ETH to xDai blockchain (UNCX or UNCL) and pick your amount.
Step 4 - Unlock & Transfer on xDai
After unlocking, 'Transfer' and then 'Continue' (12 block confirmations after signing the transaction)
Unlock & Transfer functions interact with the Ethereum blockchain. ️Expect gas fees. It is recommended to unlock more than what you plan to send, allowing you to avoid the unlock fee next time you use the bridge.
Funds are sent by default to the same address on a different blockchain. See 'Advanced' if you are willing to redirect the funds to a specific recipient address.
Step 5 - Open your wallet on xDai Network 🎉 and enjoy low fees transactions!
As it will require a transaction interacting with the ETH blockchain, gas fees will apply.
Bridging from xDai
If you are willing to bridge the other way around, the steps are the same but starting from xDai to ETH.
Properly configure xDai network on your Metamask (ideally with the same 0x wallet address)
Get at least 0.01 xDai to pay for the fee (check how to in here)
Connect your Metamask to xDai network instead of ETH network
Once the requirements are met, you can follow the same steps (1-5) as above, with ETH and xDai switched in your mind.
