Though all the Sperax and SPA functionality lives on Arbitrum now - it might happen that some early users still have SPA on the chain Sperax started with - Ethereum.
From today's perspective, SPA held on Ethereum can be used only for transfers between on-chain accounts or for depositing SPA to CEXs supporting SPA deposits on Ethereum. SPA on Ethereum can't be used for staking, yield farming (Farms on Sperax DApp), or for voting on Snapshot.
If you still have SPA on Ethereum Mainnet, you need to bridge it from Ethereum to Arbitrum in order to unlock SPA potential in DeFi.
The Arbitrum bridge accepts a wrapped form of SPA (wSPA), so first of all you must wrap your SPA on Ethereum in order to bridge it. Don’t worry, the value of your tokens will not change.
Below you can find instructions for transferring SPA to Arbitrum. Please make sure you have some ETH in your wallet to manage gas fees when wrapping and bridging SPA. Please remember: wSPA has no other function except being an intermediary token for bridging. Please don't try to send wSPA to any CEX or sell it - the transaction may fail or you can lose your tokens. Use wSPA only to bridge it to Arbitrum and get your SPA on Arbitrum.
Additionally, if your tokens do not appear after swapping or bridging, make sure you manually add SPA token addresses to your wallet.
Step 1: SPA (Ethereum Mainnet) → wSPA (Ethereum Mainnet)
Open this link.
Connect to Ethereum mainnet using your wallet using the appropriate provider.
Import wSPA token into your wallet using this token address: 0x2a95FE4c7e64e09856989F9eA0b57B9AB5f770CB
Enter the amount of SPA you want to convert to wSPA. Note that 1 SPA = 1 wSPA.
Then click on 'Swap', provide consent and send the transaction.
You can now see the wSPA tokens in your wallet.
Step 2: wSPA (Ethereum Mainnet) → SPA (Arbitrum)
Navigate to Arbitrum Bridge. (Make sure that you are bridging from Ethereum to Arbitrum One.)
Connect your wallet using the appropriate provider.
Select wSPA token by pasting its token address: (0x2a95FE4c7e64e09856989F9eA0b57B9AB5f770CB)
Enter the amount of wSPA that you want to bridge. You will receive the same amount of SPA on Arbitrum. (Note that the website may show that you will receive wSPA, but be assured that you will receive SPA on Arbitrum. You can verify that using SPA Arbitrum's token address: 0x5575552988A3A80504bBaeB1311674fCFd40aD4B)
Click on 'Move funds to Arbitrum One' and then send the transaction to give permission to transfer the capped amount of wSPA.
Send the transaction now to bridge and wait for some time for the transcation to be completed successfully.
You can track the transaction status/history on the bridge page. In some time, you should see the SPA tokens on Arbitrum in your wallet.
