1.rToken app DOES NOT support Ledger. DO NOT connect APP using Ledger, otherwise your assets will be lost.
2.DOT balance should be better more than 1 DOT to keep Polkadot account alive, otherwise you may not succeed to swap rDOT with StaFi.
rAsset App provides the cross-chain transfer function between StaFi chain and Ethereum ERC20 format for StaFi rTokens. Currently, it supports FIS, rFIS, rETH, rKSM, rDOT, and will continue to support more StaFi rTokens in the near future.
Native to ERC20
This guide mainly shows the process of “swapping native rDOT into ERC20 rDOT” and “swapping ERC20 rDOT into native rDOT”. Before using rBridge to swap rDOT between StaFi chain and Ethereum, please make sure you have Ethereum and Polkadot JS wallets first.
2.Enter the amount of rDOT and Ethereum wallet address that need to be swapped into, the amount of swapped rDOT will be automatically displayed on the second column. The amount of rDOT before and after conversion is the same. Click "Swap".

4. The “Tx Broadcasting“ page shows “Tx is broadcasting, please check your rDOT balance on your Metamask later. It may take 2-10 minutes". This process will last 2-10 minutes, please check ERC 20 rDOT balance after ending.
