Firstly, to begin using a hardware wallet directly with Sovryn, you will need… a hardware wallet! You should ensure that any hardware you acquire is genuine and has not been tampered with. It is recommended to only purchase from verified sellers and to follow the manufacturer’s guides explicitly, especially when configuring security such as keeping your seed phrase offline and in a safe place. Both official sites can be found below:
If you find you are having issues connecting to your Trezor, they recommend installing the Trezor Bridge. It is best practice to keep the firmware up-to-date, use Trezor's guide here. While interacting with your Trezor on Sovryn (and RSK in general) works, being able to send/check balances and other functions are supported via 3rd party wallets. The outline below is for My Ether Wallet.
At this point a Trezor popup or window will open, asking to “Export Ethereum public key” to MEW. Click the “Allow once for this session” button (you can choose the “Don't ask me again” checkbox if you desire), then click the green “Export” button.
Important to note here, while it is asking to export the Ethereum public key, in the near steps below it will ask you again to export the RSK public key.
Enter your pin and confirm, enter optional passphrase, press the green “Enter” button.
The Trezor page will close and you will be back at MEW's “Network and Address” selection screen. This is IMPORTANT.
Click the Network (ETH - myetherwallet.com) bar near top.
Scroll down to find RSK and click “public”.
Network bar at top should read something like “Network (RSK - public)”
Now click the Address bar to see the avalible addresses. This is also IMPORTANT.
To the right of the “HD Derivation Path” is a dropdown, click and find “RSK Mainnet” in the list.
Trezor will popup again, asking to “Export RSK public key” to MEW. Allow and Export just like first time.
Now you should see your avalible RSK addresses with any RBTC balance on them. Most cases it's the top address, so click it, the text will turn from gray to dark blue.
Check the “To Access my Wallet, I accept Terms” checkbox, allowing you to then click the now green “Access My Wallet” button.
Once connected, you'll need to add a custom token to see/send the SOV in your wallet.
On the right hand side of the page you will find “Tokens” with a list of some common RSK tokens. Click “+ Custom Tokens”
You will be presented with a “Add Custom Tokens” popup/modal.
Click the now green “Save” button. You will now see the SOV tokens appear in the “Tokens” list on same page.
Under “Dashboard” on the left hand side of the page you will find “Send” that will allow you send your SOV's to another address. Just choose “SOV” from the “Type” dropdown, it is pre-populated with RBTC.
