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.
rBridge 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.
