Liquidity Pools
How can I deposit my LP tokens?
You can stake your LP tokens under the "Pools" page. Check out our guide here.
When adding liquidity, must I provide liquidity for all tokens in a given pool? e.g. Can I simply provide DAI to the 3FER pool consisting of USDC-USDT-DAI?
No, you don’t need to provide all 3 tokens to the 3FER pool. You can provide one of the tokens that composes the pool and still get LP tokens as proof of participation in the liquidity pool.
When you remove liquidity from the 3FER pool, you are still able to choose the output token of your choice - DAI, USDC, USDT, or all 3 tokens.
Why am I not getting the total amount of $FER rewards from my staked LP token?
It is part of the mechanism that only 60% of the $FER rewards will be sent to your wallet immediately. The remaining 40% will be converted into $xFER and locked in our 30-day vault. You may choose to upgrade your vault to a longer locking duration with a higher APR. You can also withdraw $xFER once their respective locking periods have ended.
What happens if I don’t click “Harvest” for my $FER rewards?
The $FER reward will stay on the protocol instead of your wallet. You can choose to harvest anytime you want.
However, each time you harvest, only 60% of the $FER rewards will be sent to your wallet immediately. The remaining 40% of the $FER rewards will be automatically converted into $xFER and locked for 30 days in our vault. You can choose to upgrade your vault settings to a longer locking duration with a higher APR to boost your rewards. Once the locking period ends, you will be able to convert $xFER back to $FER or further lock in our vaults.
What will happen if I swap between USDC and USDT?
The swapping will be done via auto-routing from the available pools to provide the best price for you.
What is the distribution of $FER emissions between the 2FER, 3FER, and LCRO-CRO pool?
You can check the $FER rewards per day for each pool here: https://ferroprotocol.com/#/pools
Why are we launching a new pool with USDC/USDT when these are already included in the existing 3FER pool?
As a stableswap AMM, we perform deep and thorough due diligence on all the underlying stablecoins before introducing them into the liquidity pools, and we evaluate the basket of stablecoins in the 3FER pool from time to time to ensure that it provides a balance between security and usability.
Consisted of the leading stablecoins on Cronos, 2FER pool will give users enhanced stability and better rates by minimizing the imbalance between the liquidity.
Vaults
Are my $xFER tokens locked into a separate vault every time I harvest $FER from my staked LP tokens?
Yes. Different harvests will lead to $xFER being locked up in separate vaults with separate locking period end times. They are done in batches.
If I upgrade my $xFER vault setting to a longer period, will the new locking period begin from the day of change, or will the locking period passed be deducted from the new locking period?
The new locking period will begin from the day of change.
For example: If you have $xFER initially locked in the 1-month vault and 10 days later you wish to upgrade the vault to 1 year, you will be able to withdraw your $xFER 365 days from now instead of 355 days.
Direct Harvest
Where can I find this direct harvest feature?
Direct harvest is a feature that allows users to harvest their $FER rewards and lock their $FER rewards directly to our $xFER vault with ease, instead of taking the additional steps to stake their $FER for $xFER and lock into a vault. This applies to those who have staked their LP tokens in Pool for $FER rewards, as well as those who have locked $xFER into vaults for extra $FER rewards.
If you have $FER rewards from staked LP in Pools
Go to “Pools” > “Stake Liquidity” > “Pending Rewards”
It is only available if you are a liquidity provider of the pool and have staked your LP token for additional rewards
When you click “Harvest”, you will be prompted to select Harvest Options - whether to harvest straight to your wallet, or stake into a $xFER vault of your choice.
Please note that direct harvest is only applicable to 60% of $FER. The remaining 40% will be converted to $xFER and locked into 1-month vault directly
If you have $FER rewards from locked $xFER in Vaults
Go to “Stake” > “Vaults” > “Pending Rewards” It is only available if you have locked your $xFER into a vault for additional rewards
When you click “Harvest”, you will be prompted to select Harvest Options - whether to harvest straight to your wallet, or stake into a $xFER vault of your choice.
Please note that the harvest option is applicable to 100% of $FER rewards harvested from Vaults. This means that
By choosing harvest straight to your wallet, 100% of the $FER rewards will be credited to your wallet
By choosing direct harvest to a vault, 100% of the $FER rewards will be converted into $xFER and locked into the vault of your choice
There will NOT be a 60%/40% split of which 40% is automatically locked into the 1-month vault
For the $FER rewards generated from staked LP in a Pool, will I be able to direct harvest only the 60% of $FER to go straight into vault instead of my wallet, or will I be able to adjust the locking period of the 40% in one go as well?
Direct harvest is only applicable to the 60% of $FER. You can choose to harvest the 60% of $FER straight to your wallet, or directly to a $xFER vault of your choice. The remaining 40% of the $FER rewards will still be converted into $xFER at the prevailing exchange rate and locked into the 1-month vault without having the option to adjust the locking period.
Under the “Rewards” page, if I want to “Harvest All” $FER rewards generated from multiple pools that I’ve participated in, do I get to select the harvest options separately for the individual pools?
No. Under the “Rewards” page, if you select “Harvest All”, you will only be prompted to select Harvest Options once and the option you have selected will be applied to the $FER rewards to be harvested from all the pools you’ve participated in.
Example: I have participated in both 2FER and 3FER pool with 100 $FER to be harvested from each pool.
If I select “To My Wallet”, 60% of the $FER rewards from each pool will be harvested to my wallet directly, i.e. 60 $FER from 2FER to wallet and 60 $FER from 3FER to wallet.
If I select “Stake into xFER vault” and choose the 4-year vault, 60% of the $FER rewards from each pool will be harvested and locked into the 4-year vault, i.e. 60 $FER from 2FER to be converted to $xFER at prevailing exchange rate and locked into 4-year vault, and 60 $FER from 3FER to be locked into the 4 year-vault as well.
The remaining 40 $FER from each pool will be converted into $xFER and locked into the 1-month vault directly.
If you wish to select different locking option for the pools you’ve participated in, you can
Stay on “Rewards” page and click the “Harvest” button for the individual pools separately
Navigate to “Pools” > “Stake Liquidity” > “Pending Rewards”, then click “Harvest” and choose the desired Harvest Option for each of the pool
Pool Boost
I've staked xFER and multiple NFTs to obtain Boost Power. If I choose to boost 2 pools, will the Boost Power be split between the pools?
Apart from your staked xFER and NFTs, Boost Power depends on
The amount of LP you have staked in the pool and
Your share (%) of the pool
The same Boost Multipliers will be applied to both pools, but each pool may have a different Boost Power depending on your position in the pool.
Is there any expiration date for Pool Boost?
The Pool Boost will be effective on the selected pools as long as there is xFER staked in the vault. Even after the locking duration ends, the Pool Boost will remain effective until you withdraw all the xFER from the vault.
What will happen to my NFTs if I withdraw xFER from the vault and remove liquidity pool from the pool?
You may lose your NFTs if you don’t unstake them before withdrawing xFER and removing staked liquidity from the pool. However, in the event that you have not unstaked the NFT before removing liquidity, you can still add and stake liquidity back to the pool to perform NFT unstaking.
You can refer to this user guide to learn more about NFT unstaking.
Are the Boost Power and resulting APR fixed to the number I'm seeing?
Boost Power depends on
The amount of LP you have staked in the pool and
Your share (%) of the pool
It will fluctuate depending on the other participants of the pool. The Boost Power and APR displayed are only estimated for your reference. They do not represent guaranteed returns in the Boosted Pool.
What is the emission split between base rewards and Pool Boost rewards?
Base rewards accounts for 90% of the $FER emission, while Pool Boost rewards accounts for 10%.
General
What are the different approval requests that I will encounter on the protocol?
Approve Token Spend Limit
This will appear when you interact with the smart contract for the first time and you may need to approve spend limit for multiple tokens depending on the transaction
Transaction Approval
This approval is applicable to transactions such as swapping tokens, adding/removing liquidity, and depositing tokens.
How is APR calculated for Pools?
APR will depend on the price of $FER and will fluctuate according to the $FER price discovery and total TVL within the pool.
APR may significantly drop when there are more users staking their LP tokens, as the $FER rewards will be shared among more users. However, as more users come and swap using the protocol, protocol revenue will increase, part of which will be distributed to users holding LP tokens of the pool, resulting in a higher APR.
What are the differences in rewards between LP Tokens, $FER, and $xFER?
LP Tokens
Where can I get the token?
By providing liquidity to one of the liquidity pools under the “Pool” page
What rewards can I get?
You will get a cut from the swap fees of the pool in proportion to your share of the pool
Swap fee will be distributed to you in the form of LP tokens as they are auto-compounded to your LP token
As a result, the value of LP tokens you have will increase, which will change the amount of liquidity you can get back upon withdrawal
What can I do with it?
Hold the LP tokens and earn swap fee from the liquidity pool Stake your LP tokens and earn $FER based on the pool APR Remove liquidity from the liquidity pool
$FER
Where can I get the token?
Get LP tokens by providing liquidity and stake your LP tokens for $FER under the “Pools” page
Earn extra $FER by staking $FER for $xFER at the prevailing exchange rate at any time under the “Stake FER” page, then boost $FER rewards by locking your $xFER token in vaults under the “xFER Vault” page
Convert your unlocked $xFER back to $FER by unstaking $FER under the “Stake FER” page
Swap on VVS Finance or purchase on Crypto.com Exchange
What rewards can I get?
$FER itself is the main reward/incentive token in the protocol
What can I do with it?
Stake $FER for $xFER to earn extra $FER rewards based on the Staking APR. Locking your $xFER in vaults will boost your rewards based on the Vault APR.
Participate in the FER-VVS Farm on VVS Finance for additional rewards
Trade on VVS Finance or Crypto.com Exchange
$xFER
What rewards can I get?
$xFER is the yield-bearing token that gives you extra $FER rewards
By locking your $xFER into our vaults with different locking periods, you can yield more rewards with higher APRs
What can I do with it?
Hold $xFER and get extra $FER rewards
Lock $xFER into the vault of your choice and boost $FER rewards depending on the locking period and APR
Convert your unlocked $xFER back to $FER by unstaking $FER
What is the maximum supply of $FER?
$FER has a maximum supply of 5 Billion. Read more about it in our Whitepaper.
You can also track our protocol's statistics on our landing page, or track $FER on Cronoscan here.
Where can I find the Protocol Roadmap?
You can read more about our Protocol Roadmap here.
When are Governance and Voting coming?
It is part of our roadmap to establish a protocol with trustless governance but we aim to stabilize the platform before gradually passing the full governance to the community. Look out for our future announcements!
