No. rToken app does not support Ledger. Please remember not to connect APP using Ledger, otherwise your assets will be lost.
1) There will be no need to wait for 7 days to unbond the staked BNB assets. Users can transfer, mortgage, and trade rBNB assets at any time to liberate liquidity and hedge price risks.
2) There is no need to learn the complicated Binance Chain’s Tendermint BFT consensus mechanism or staking reward calculation rules if you want to maximize staking rewards. With the rBNB product, users only need to follow a few steps to deposit BNB into the rBNB contract, which will automatically select the best validator for delegation by the profit maximization strategy.
Please follow this guide to stake BNB: https://docs.stafi.io/rtoken-app/rbnb-solution/staker-guide
The unbonding period of rBNB App is 14 days, though that of BNB staking on BSC is 7 days.
This is because the staking module of BNB staking on BC only supports to unbond once every 7 days. Therefore, if more than one user unbond through StaFi rBNB App, StaFi rBNB contract has to collect all the redemption asks in the first 7 days, then unbond from the BC chain in the next 7 days.
BEP20 Contract Address: 0xf027e525d491ef6ffcc478555fbb3cfabb3406a6
You can swap rBNB tokens into BEP20 format at 1:1 ratio through the swapping function in rAsset. Please refer to this guide to swap native rBNB into BEP20 format: https://docs.stafi.io/rtoken-app/rasset/swap-guide
The rBNB exchange rate Ci grows with the increase in staking income. It is determined by the total number of BNB locked in the staking contract Qstk, the total number of redeemed BNB Qred, the number of staking rewards Qrew, the number of slashes Qslh, the commission rate Rcom, the total number of rBNB issued M, and the total number of burnt rBNB N. The calculation formula is as follows:
1) When the rBNB App is launched, rBridge will at the same time support rBNB two-way cross-chain bridge function from StaFi chain to BSC, so that users can have access to DeFi applications on BSC by using rBridge product.
2) In the near future, StaFi will list rBNB tokens on DEXes such as Pancake, and launch liquidity mining incentive campaigns to ensure the liquidity of the pairs.
Stake BNB: N * (StaFi chain Gas Fee + Binance Gas Fee), and the payment is made by FIS, StaFi mainnet token.In most cases, N is set to 2.
Unbond BNB: 0.2% redemption fee(based on the amount of unbonded rBNB and 10% Staking Reward Commission(based on the total staking rewards generated).
After the user completes the "Redeem" operation, s/he has to wait for around 14 days to get the redeemed BNB tokens, which will be automatically sent to the users’ designated account after the lock-up period.
