Singular cross-chain mortgage NFT function is officially launched. This feature has been implemented to support cross-chain lending of Ethereum ecosystem NFT assets in Layer2. According to test data, this feature can save you a lot of gas, up to more than 90%.
This guide will walk you through how to use this feature more easily and quickly.(This article uses “The Weirdo Ghost Gang” as an example for guidance)
Open Singular, confirm that the network environment in the upper right corner is set to Ethereum, and click on “The Weirdo Ghost Gang” in the NFT list.
Click the copy “Less gas fee? Try to borrow your NFTs on Layer 2! > > >” below the borrow button in the upper right corner to enter the NFT cross-chain page
Your The Weirdo Ghost Gang NFT will be displayed on the left side of the page. It is recommended to choose batch NFTs or click’all ‘to select all NFTs for better gas cost savings!
After selecting the NFT, click on the switch at the bottom right, authorize the NFT for cross-chain transfer. MetaMask will prompt a pop-up; click “Confirm.” After authorization, click the “Transfer” button. MetaMask will again show a pop-up; click “Confirm” to initiate the cross-chain transfer to Arbitrum.
The cross-chain process generally takes about ten minutes. You can click on the LayerZerosan pop-up to check the cross-chain status on LayerZero while waiting.
When the page displays a success pop-up or when the LayerZerosan status shows ‘Delivered,’ your NFT has successfully crossed over to Arbitrum.
Click on ‘Switch Layer 2 to borrow’ in the pop-up or directly click on the upper right corner to switch to the Arbitrum network. After confirming the network switch in MetaMask, you can navigate to the Arbitrum page for The Weirdo Ghost Gang. Click on the ‘borrow’ button in the upper right corner to enter the collateralization process. Complete the borrowing process.
Under Arbitrum network, enter dashboard-borrows and click’Rapayment ‘in the loan list to complete the repayment process. After successful repayment, the pop-up window will prompt’transfer NFT to layer1'. You can choose to click’ok ‘to enter the cross-chain page and cross the NFT back to Layer1. If you still want to continue mortgaging the NFT in Layer2, you can choose’Later’ or close the pop-up.
Make sure to enter the Little Ghost page under Arbitrum network, click’Transfer your NFTs’ under the Borrow button, and enter the cross-chain page.
Here, you can choose to cross-chain the NFT that has already been repaid back to Ethereum, or click the switch button between networks to cross more Layer1 NFTs. The steps for crossing back are the same as above, and you need to authorize to initiate the transfer. After waiting, you can click the button’Switch Layer1 to check your NFT ‘to switch to view your NFT.
[Common Error Reminder]
1、The total cost(gas*gas fee+value) of executing this transaction exceeds the balance of the account.
It means your account balance is insufficient to cover the gas and fees required for the cross-chain process. Please check and replenish the balance in your Layer1 and Layer2 network wallets.
