# ❓ FAQs

> In case you couldn't find the answers to your questions elsewhere... 🙈

#### Risks

<Accordion title="What are the risks of staking with Spirals?">
  Staking with Spirals means that you can always redeem the staked asset. Let's
  break down what that means for token supported today.

  ### Celo

  When you stake Celo with Spirals, that is staked on validators that power Celo's
  L1 consensus mechanism. Since L1 staking guarantees that staked Celo can be
  withdrawn\*, Spirals is also able to make this claim. Today, we do this through
  an audited liquid staking protocol called
  [Staked Celo](https://docs.stcelo.xyz/).

  *\*One small caveat here is*
  [*slashing penalties*](https://docs.celo.org/protocol/pos/penalties)*. This is
  why Staked Celo has a strict criteria for validator selection & rotation to
  minimize the probability of slashing.*

  ### cUSD

  When you stake cUSD with Spirals, our vaults deposit cUSD as collateral into a
  decentralized lending protocol called [Moola Market](https://moola.market/)
  (fork of Aave V2). Moola Market tracks a health factor for each depositor that
  measures the value of their collateral against the value of their debt. If the
  ratio falls below 1 (loan becomes under collateralized), then a liquidation
  event is triggered.

  This stability mechanism ensures that Moola's lending pools are
  over-collateralized so that there should always be enough liquidity to allow our
  vaults to withdraw cUSD on behalf of a Spirals staker. On top of that, Spirals
  does not take out any loans on Moola Market so our underlying cUSD collateral is
  safe and will never be liquidated.

<Accordion title="Have the Spirals smart contracts been audited?">
  Yes! We completed our first audit with [Verilog
  Solutions](https://www.verilog.solutions/audits/spirals/) on September 12th, 2022.

#### Impact

<Accordion title="How is impact calculated?">
  Today, the impact of a Spirals user can be understood as "the amount of positive
  climate work I've helped bring to life." Although not every project in the
  portfolio focuses on sequestering carbon, we use tCO2 (tons of carbon) as a base
  unit to understand our physical climate impact and an estimated cost of \$15/ton
  for nature-based carbon removal.

  For example, let's say we have a user who is staking $10,000 across all green
    token vaults (5% avg APY) and leaves it staked for a year. Then this user is
    contributing $500 to climate projects, which equates to 33.33 tCO2 of physical
  climate impact.

  Conversion to other units like number of miles walked instead of driven was
  calculated using numbers used by an open-sourced carbon footprint calculator
  published by Berkley researchers:

  [https://coolclimate.berkeley.edu/calculator](https://coolclimate.berkeley.edu/calculator)
</Accordion>

<Accordion title="Is impact double-counted?">
  No, because users of Spirals do not get to claim the carbon offset associated
  with their yield contributions. This is instead understood to be the amount of
  positive climate work they've helped bring to life, but is not contributing to
  their individual carbon neutrality.
</Accordion>

#### Governance

<Accordion title="How are projects selected?">
  An independent council of climate experts review each climate impact project to
  ensure we are listing high quality projects. This process will be eventually
  completely open-sourced with an opportunity for SPRL token holders to become
  engaged as well.

  Learn more about how that works today
  [here](https://docs.spirals.so/climate-impact/project-review-process).
</Accordion>

<Accordion title="Is Spirals a DAO?">
  Eventually we will be, yes! Our approach to building Spirals is best summarized
  by ***progressive decentralization***.

  For now we are mostly making decisions as a core team to learn quickly and
  understand how things can be systematized. Our intention is to gradually
  transition the decision-making process to on-chain governance coordinated by the
  \$SPRL token. More on that soon!
</Accordion>

#### Supported Platforms

<Accordion title="What chains are supported today?">
  Today we support Celo. Soon we will support Ethereum and Polygon as well.
</Accordion>

<Accordion title="What wallets are supported today?">
  Today we support Metamask, Coinbase Wallet and most other wallets through
  WalletConnect (Valora, Rainbow Wallet, etc.).

  We also support Gnosis Safes for multisig staking!

#### Fees

<Accordion title="What are the fees for staking?">
  As a quick refresher, there are 3 types of projects on Spirals:

  * **Collection** - climate impact projects funded through forward contracts,
    part of the default Spirals Collection

  * **Impact** - climate impact projects, either `verified` or `pending review`
    by climate council

  * **Ecosystem** - projects that strengthen the ReFi ecosystem

  The fees for staking depends on the type of project you are supporting. If a fee
  applies, it is taken from the staking yield you earn through the protocol, which
  means that you will still be able to withdraw 100% of your principal deposit.

  * **Collection -** no fees

  * **Impact** - 2% for verified projects, 5% for unverified projects

  * **Ecosystem** - flat 5% fee
</Accordion>

<Accordion title="What are the fees for getting listed as a project?">
  As a project, there are **no fees** for listing your project and setting up a
  project page 🙂
