How to Transfer ROSE into Emerald ParaTime
Transferring ROSE from Oasis Consensus to Emerald ParaTime using Oasis Wallet Browser Extension.

About

Emerald is an EVM-compatible blockchain running inside the Oasis ParaTime. Because the balance of your ROSE wallet is stored on the consensus layer - outside of ParaTime's reach - there is a special mechanism for Emerald to access your tokens. Namely, the Deposit action will create the allowance policy for the provided ParaTime to access the specific amount of your ROSE and to be used by the provided Ethereum-compatible wallet. The Withdrawal action in contrast transfers ROSE back from the ParaTime to your wallet on the consensus layer and removes the allowance.
Currently, only the Oasis Wallet Browser Extension supports a graphical user interface to perform deposit and withdrawal actions.

Managing your Emerald account with Oasis Wallet Browser Extension

Firstly, install the Oasis Wallet Browser extension, restore your existing or create a new Oasis wallet as described in the Oasis Wallet Browser Extension chapter.

Once done, you will see your balance on the Oasis consensus layer. Next, we will import your Ethereum wallet to be used in Emerald.

Importing Ethereum wallet account

In the top-right corner, click your account icon to open the Account management menu.
Account Management - Importing Accounts
Click "Import" and select "Ethereum-compatible Private Key" to import your existing Ethereum Account address.
We assume that you already have your Ethereum keypair. If you don’t have one yet, please go and create one. Store your Private Key, because you will need it in the Oasis Wallet Browser Extension.
Importing Ethereum-compatible Account with Private Key
Fill in the "Account name" that will appear later in the Account Management screen.

Next, paste your hex-encoded Ethereum private key.
You will need to import the private key and not the mnemonics. You can derive a private key from the mnemonics with BIP39->BIP44 converter. For example by using the Ian Cole's tool offline.
Entering Ethereum address Private Key (BIP44)
Your newly imported Ethereum account will appear under the "Ethereum-compatible Account" section in the Account Management screen. Check that the Ethereum address shown at the bottom matches the address that was shown to you when you generated the Ethereum key.
In older versions of the Oasis Wallet Browser Extension there was also a bech32-encoded version of the Ethereum address shown in the Ethereum-compatible wallet. This address is only used internally for setting the allowance policy on the Oasis network. If you encounter this, you should immediately update your Wallet Extension! The bech32-encoded address of the Ethereum-compatible account must never be used for transferring ROSE to. The signature schemes are incompatible (ECDSA versus ed25519) and those tokens would not be accessible anymore!

Depositing ROSE To Emerald ParaTime

Now, you can transfer your ROSE to Emerald ParaTime. Navigate to the "ParaTimes" tab. Notice two ParaTimes: Emerald and Cipher with the corresponding ParaTime IDs. Under Emerald click on the "To ParaTime" button.
ParaTimes - Transfer ROSE To Emerald
Fill in the the "Amount" of ROSE that you want to transfer to Emerald ParaTime and your Ethereum-compatible address in the "To" field you imported/created before. Then, click "Next", review and confirm the transaction.
Sending ROSE to Emerald
At the time of writing, depositing and withdrawing ROSE to and from ParaTimes works for Oasis wallets imported from the private key or the mnemonic only. Support for the Ledger hardware wallet is not implemented yet.

Verifying ROSE balance on Emerald ParaTime

If everything went well, your entered amount of ROSE was sent to the Ethereum-compatible address in Emerald. Let's verify that your ROSE safely arrived on your Emerald Ethereum wallet.

Wallet Browser Extension

You can check the balance in the Oasis Wallet extension by opening the "Account Management" tab and selecting your Ethereum-compatible account which you used to send ROSE to. Then click on the back arrow and navigate to the "ParaTimes" tab. Under Emerald you will notice the available amount of your ROSE.

Metamask

You can verify your balance in Metamask (or a built-in wallet in the Brave browser). First, install the extension in your favorite browser and add the Emerald Network (refer to the Web3 gateway parameters here for either Emerald Mainnet or Testnet). Then, import your Ethereum keypair and your balance should immediately be visible.
Brave wallet network configuration requires you to enter Chain's currency decimals for ROSE: 18)

Withdrawing ROSE from Emerald ParaTime

You can withdraw your ROSE from Emerald back to your Oasis wallet by first selecting your Ethereum-compatible account in the Account Management screen. Next, switch to ParaTimes tab and click on the "To Consensus" button near the Emerald entry. Fill in the "Amount" and your bech32-encoded Oasis wallet address and confirm the withdrawal. In a few moments you will have your ROSE accessible on the consensus layer.
If you want to transfer ROSE to an exchange and you currently have them deposited on Emerald ParaTime, we strongly recommend that you withdraw ROSE to your Oasis wallet first and then perform a regular token transfer to your Oasis address on the exchange! The ParaTime's withdrawal action is a special transaction (consensus.Withdraw compared to staking.Transfer) and some exchanges may not recognize this transaction as valid transaction for funding your account on the exchange.

Verifying Emerald ParaTime deposits and withdrawals

To verify and validate your transactions (deposits, withdrawals) on Emerald you can use our official Oasis Scan block explorer. Enter your oasis1 address and press Search. Then navigate to Transactions section and press "ParaTime" button next to Consensus. You will be able to see all transactions made from Ethereum compatible address (0x) you used in Emerald to your Consensus (oasis1) address where you sent your ROSE to.

Furthermore, you can click on Tx Hash of any transaction you see on the list. You will find your from Ethereum-compatible address, your to destination Consensus address, and amount of ROSE transferred.

Be aware that the Oasis Scan Blockchain Explorer is built for Consensus layer. If you want to explore Emerald ParaTime (0x addresses, Token Transfers, Contract Calls, etc.), you have to use Emerald Blockchain Explorer.
