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 a 9 days unbonding period to withdraw the staked MATIC assets. Users can transfer and trade rMATIC assets at any time to liberate liquidity and hedge price risks.
2) There is no need to learn the complicated PoS consensus (based on Tendermint) mechanism or staking reward calculation rules. With the rMATIC App, users only need to follow a few steps to deposit MATIC into the rMATIC contract, which will automatically select the best validator for delegation by the profit maximization strategy.
Please follow this guide to stake MATIC: https://docs.stafi.io/rtoken-app/rmatic-solution/staker-guide
Date: Around 9 days
Commission: 0.2% unstake fee(based on the amount of unstaked rMATIC)
Please note that the redemption process may be delayed due to the abnormal condition of the target chain (like upgrading) or the downtime of RPC service, or server exception, etc.
You can swap rMATIC tokens into ERC-20 format at 1:1 ratio through the swapping function in rAsset. Please refer to this guide to swap native rMATIC into ERC20 format: https://docs.stafi.io/rtoken-app/rasset/swap-guide
The rMATIC exchange rate Ci grows with the increase in staking income. It is determined by the total number of MATIC locked in the staking contract Qstk, the total number of redeemed MATIC Qred, the number of staking rewards Qrew, the number of slashes Qslh, the commission rate Rcom, the total number of rMATIC issued M, and the total number of burnt rMATIC N. The calculation formula is as follows:
1) When the rMATIC product is launched, rBridge will support rMATIC two-way cross-chain bridge function from StaFi chain to Ethereum at the same time, so that users can have access to DeFi applications on Ethereum by using rBridge product.
3) StaFi will not only support the circulation of rMATIC in the Ethereum ecosystem but also empower rMATIC’s engagement in the DeFi protocol of Polygon through cross-chain bridge services.
Stake MATIC: N * (StaFi chain Gas Fee + Ethereum Gas Fee), and the payment is made by FIS, StaFi mainnet token.In most cases, N is set to 2.
Unbond MATIC: 0.2% redemption fee(based on the amount of unbonded rMATIC 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 9 days to get the redeemed MATIC tokens, which will be automatically sent to the users’ designated account after the lock-up period.
