Over the months StaFi team has been working tirelessly towards the development of rBridge, A cross-chain bridge on Ethereum, rBridge will act as a channel linking StaFi mainnet assets and Ethereum chains. Users can exchange FIS for ERC 20 FIS at a 1:1 rate by using rBridge. Thereafter, they will be able to access transactions, lending and other applications of the DeFi world of Ethereum.

Again, rBridge will help with the cross-chain inter-operation between assets on the StaFi mainnet and other ecosystems, including Ethereum, Polkadot, and Cosmos. 

StaFi team hereby announces to the communities and public
that rBridge Beta is officially launched.

Here is a guide on how to use/navigate through the rBridge. (https://docs.stafi.io/rproduct/rbridge/guide-on-mainnet)

 CONFIRM WHETHER THE $FIS HAS ARRIVED
 

 (1) Download metamask plugin wallet: https://metamask.io/ if you don't have one.
Import your Ethereum account. This wallet supports import by private key or JS file.

Note: The Ethereum account you import must be the one you use for swap, or the balance will be 0 when you add a token.

 (4) Confirm whether the balance of FIS is consistent with what you entered during swap operation. If so, that means you have successfully swapped.

If the FIS balance is 0, check the Ethereum address of this metamask wallet is the same as what you entered when you swapped. If not, please re-enter the Ethereum address.

In less than 1 minute, the user will receive FIS tokens in ERC 20.

It should be noted that rBridge makes it really convenient for users so that they do not need to pay the commission by their ETH wallet while connecting to the StaFi wallet. We will pay on behalf of them, so they only need to pay FIS by the current FIS/ETH exchange rate.

To encourage everyone to use rBridge products, we will not charge any service fees at the beginning.
