Easier than you thought, but u wudnt blv it!
Just follow these steps:
Go to https://bridge.arbitrum.io/ on a desktop browser
Connect your browser wallet (Metamask, Rabby, etc) and select Arbitrum One as the network
Click on token selection drop-down, paste the following Arbitrum token contract and click Add. The $ABI token will show up:
Read, understand & check ✅ the disclaimers, and click Continue once ready.
Approve the transaction pop-up and your funds will be on their way!
Once they are bridged over, you will need to come back to this website and Claim your tokens. You can also click on the drop-down next to your wallet and select Transactions to see the current status.
Note: When claiming tokens on the Mainnet side, you will need to sign another transaction and pay ETH Mainnet gas fees which can vary a lot based on network load at the time.
If you wish to bridge from ETH Mainnet over to Arbitrum, the flow is exactly the same, just in reverse. If you run into trouble at any point, feel free to hit up one of the mods or team members in our Discord, and they will be happy to help you out!
Happy Bridging!
