Interacting with the Autobahn Network requires having the TXL in your wallet to make transactions.
To deposit and withdraw TXL between BNB Smart Chain and the Autobahn Network, a bridging solution is, or will, be provided, respectively. To bridge into and out of the Autobahn Network, users will have two options:
Native Gateway (will be released soon): Via CrossChainBridge.org, users will have the option to choose the native gateway to move TXL between BNB Smart Chain and the Autobahn Network. Due to the nature of Optimistic Rollups, this process can take up to 7 days as the Optimistic proofs need to be validated on the BNB blockchain. The native gateway is for TXL and WBNB (Wrapped BNB) bridging only. Here it should be noted that there is no native BNB on L2 but only WBNB. Wrapped BNB is an ERC20 compatible version of BNB.
Fast Bridge (will be released subsequent to bridging option 1): The CrossChainBridge.org will offer a second bridging option, the “fast” bridge. Using the fast bridge, which works with deposits into, and withdrawals from, liquidity pools provided in both networks and thus circumvents the 7-day window mentioned above (while maintaining security), users can withdraw and deposit in just 1-5 minutes, depending on blocktimes. The fast exit will be available for TXL, WBNB and any other token supported by the Autobahn Network - if sufficient liquidity is available within CrossChainBridge.org.
Developers have a third option (the only option in Canary Launch Phase 1) - the Deposit via Contract Call. For instruction see here.
