Guide on bringing your assets, i.e. ETH, USDC, USDT, from Ethereum, BSC, Polygon or Avalanche to Emerald ParaTime using the Wormhole token bridge.
Emerald is an Oasis ParaTime providing an Ethereum-compatible blockchain for the Oasis Network. If you want to use any dApp for DEX, NFT and similar built on Emerald, you will have to transfer your assets into the Emerald ParaTime.
To transfer your ROSE tokens into Emerald, follow How to Transfer ROSE into Emerald ParaTime.
To transfer (i.e. bridge and wrap) your ETH and ERC20 tokens, follow this guide. It will show you how to use Wormhole Bridge to seamlessly transfer your tokens from Ethereum, Solana, Avalanche, BSC, Terra or Polygon to the Oasis Network.
Using Wormhole Bridge
Open Wormhole Bridge and Connect your Account
First, get your assets ready in your MetaMask to be transferred over to Oasis. Then navigate to the Wormhole Bridge’s website and click on Transfer Tokens to open the Wormhole Bridge Transfer application.
Step 1 (Source) is to point Source to the network from where you want to transfer your tokens to Ethereum and set the Target to Oasis. Then click Connect to connect your wallet with the Wormhole Bridge.
Transfer Assets to Oasis
Now you can select an asset from all available assets in your wallet, e.g. ETH, to be transferred to Oasis.
Select the asset to be transferred
Make sure, that you always have enough ETH (or other assets) for paying gas fees, not only to transfer (i.e. bridge) the assets to Oasis, but also to redeem any assets back to Ethereum.
Choose the Amount of tokens you want to transfer and click Next. If your MetaMask wallet is switched to some other network, the Wormhole bridge will ask you to switch to the correct network (e.g. Ethereum Mainnet).
You will then proceed to Step 2 (Target). Your MetaMask wallet will show up again and ask you to switch to the Emerald Mainnet network because that is where your ETH will be wrapped to wETH.
The recipient address defaults to the source address on the Ethereum network. You can transfer your ETH into a different destination Ethereum account, by switching the currently opened account in MetaMask. The Wormhole Bridge web app will automatically switch the recipient address accordingly.
Next, confirm the recipient address and the amount of WETH tokens to be transferred (i.e. bridged) and click Next.
Confirm your recipient address
Step 3 (Send tokens) is to transfer the tokens to the Wormhole Bridge. MetaMask will ask you to switch back to the Ethereum Mainnet so you will be able to confirm your transaction and commence the transfer. Click Transfer.
If you chose to transfer your ETH into a different destination Ethereum account, you will need to switch the currently opened account in MetaMask back to the same account as used in Step 1.
Send tokens to Wormhole
Confirm the Transfer of ETH from Ethereum to wETH on Oasis Emerald by clicking Confirm.
Confirm the transfer ETH->WETH
If you use a Ledger hardware wallet backed Ethereum account, you will need to enable “Blind signing” or “Contract data” in the Ethereum Ledger app’s settings to be able to sign the transaction.
You will have to wait for the confirmations on Ethereum before redeeming your new wETH tokens in Oasis Emerald.
Wait for Ethereum confirmations
Now you are ready to redeem your tokens on the Oasis Emerald. Confirm the wallet approval in your MetaMask.
Confirm Redeeming your wETH
Congratulations! You just bridged your first ETH (your chosen asset) to wETH on Oasis Emerald.
ETH to wETH bridging completed
We suggest that you add the new contract address for wETH (your newly wrapped asset) immediately after the transaction is confirmed, so you will see them available in your wallet.
Using Wrapped Assets on Oasis
Now you can start using that wrapped assets across new Oasis dApps like the first DEX build on Emerald — YuzuSwap, where you can swap, provide liquidity and farm YUZU rewards.
Make sure that your MetaMask is connected to the Emerald Mainnet network. You can find network parameters here.
