Frequently Asked Questions posed by Hundred Finance users

General

Is Hundred Finance safe?

As with all cutting edge financial services, there are elements of risk to interacting with cryptocurrency and platforms such as Hundred Finance. In the case of an Ethereum-based protocol, the most pressing of these are smart contract vulnerabilities that affect the platform and the liquidation risk faced by end users. No platform should be considered 100% safe. That said, Hundred Finance has and continues to be extensively tested in order to mitigate risk and provide the UI necessary to protect user funds from undue loss. Smart contracts are reviewed thoroughly and risk assessments are conducted prior to additions to the protocols suite of services. What is more, a bug bounty program has now also been instigated to incentivize positive analysis of the protocol’s mechanics and infrastructure.

Where are my assets stored?

Assets supplied to Hundred Finance are sent to smart contracts. Only users have access to and full control over their funds. It is essential, however, that users properly secure the private keys of the wallets used to interact with the protocol. Loss of private keys equates with loss of funds as the protocol or the team behind it have no means of retrieving access.

Does Hundred Finance charge fees?

Supplying assets to Hundred Finance is free. There is, however, a small, asset-specific fee generated from interest spreads. Referred to as the Reserve Factor, these fees are used to support the ecosystem and contribute to its growth.

The reserve factor used for each asset is recorded within this document.

Where does the interest accrued by suppliers come from?

Interest paid by borrowers is distributed to all investors of the same asset on a pro rata basis.

HND Staking, Voting and APR Boosts

What is the difference between supplying a token and staking a token?

Supplying a token to Hundred Finance simply means making it available to users who will pay interest on any amount they borrow. This interest, minus the reserve factor, is distributed to all those supplying the asset proportional to their portion of the available liquidity. Staking, on the other hand, refers to depositing a qualifying hTOKEN (that are received when an asset has been supplied) in its own staking contract in order to receive HND tokens in addition to the underlying interest received from borrowers.

It is important to note that all hTOKENS act as collateral and will thus allow those who supply the underlying assets to borrow against them as long as those hTOKENS remain in their wallet. As staking entails transferring hTOKENS out of a user's wallet, stakers cease to be able to borrow against them.

Why are stablecoin APRs displayed as a range?

Hundred Finance allows users to stake their stablecoin-derived hTOKENS for HND emissions (assuming those hTOKENS are not collateralizing a borrow). These HND rewards are emitted at a default 1.0x but can be boosted up to 2.5x by staking HND. Until the hTOKENS have been staked, the protocol is unable to determine what boost an account has. For that reason, only once this has been done will the UI display the user's current APR.

Where do I go to use HND to boost my stablecoin rewards?

The staking, voting and boost UIs for each chain can be accessed from https://vote.hundred.finance.

How long can HND be staked?

HND tokens can be staked for a maximum period of 4 years. The formula for received veHND per 1 HND locked is as follows:

1 HND 4 year lock = 1 veHND

1 HND 2 year lock = 0.5 veHND

1 HND 1 year lock = 0.25 veHND

I locked my HND but my veHND balance is decreasing. What's going on?

The veHND balance, which represents the voting power, decreases over time. Once the balance has reached zero, the HND will no longer be locked and can be withdrawn.

Can I relock HND to maintain my voting power?

Claimed HND rewards can be locked to obtain additional voting power.

Do I need to stake HND to get the full APR?

In order to boost your APR on a qualifying hTOKEN, the hToken needs to be staked in the applicable staking contract using an account that has also staked HND to receive veHND. The boost received can be anything up to 2.5x depending on vote distribution across gauges and the composition of the staking contract, including factors such as total liquidity, an accounts own portion of the total liquidity and its relative veHND holdings when compared to other accounts currently staking.

How exactly is my boost calculated using my staked veHND?

The boost depends on the following parameters:

DollarProvided = $ amount of staked stable coin

TotalLiquidity = $ total amount of stable coin in the pool

VotingBalance = own amount of veHND locked

Voting Total = total amount of veHND locked

The value would be the minimum between the DollarProvided and a calculated value as per below

Min(DollarProvided, (DollarProvided * 40 / 100) + TotalLiquidty * VotingBalance /Voting Total * 60 / 100)

Is there a calculator or a guide on how much HND is needed to receive the maximum boost?

Yes, within the vote.hundred.finance UI we have built a calculator that can be used to estimate the amount of veHND to get a particular boost on any given gauge. Furthermore, the Staking UI includes at the bottom of the page a readout of a connected account's current boost on qualifying staked assets, as well as a dynamic calculation of how much additional veHND would be needed in that instance to boost the asset's APR to the maximum 2.5x. This figure appears as a popup modal when a user hovers over a current boost amount that is less than 2.5x.

What is gauge voting?

Gauge voting is used to assert your wish for where HND rewards are emitted using your veHND as voting weight. The gauges will receive a portion of HND each epoch proportional to the total amount of vote weight assigned to them.

Can I change my vote weights used in gauge voting?

Yes, but you can only change votes for each gauge once every 10 days. If you have voted already on a gauge, you will need to reset your vote and wait for the cooldown to complete.

If I can only vote once every 10 days but the epoch lasts 7, will I miss out on boosted APR during those 3 days?

Voting does not directly boost qualification, instead it determines the distribution of HND rewards. Assuming you voted for your the qualifying assets you have staked, you will always receive some form of boost even if voting for an epoch you were unable to influence heavily favored assets you do not have staked. With this in mind, votes could be picked just once and never altered, though the "gamification" of the protocol through tactical voting and the 10-day cooldown is intended an result of the veHND system.

Can I vote for more than one gauge?

Yes, but with a total vote weight distribution of no greater than 100. This is because voting power is proportionally distributed across all gauges. So, as long as the sum of the distribution does not exceed 100, the vote transaction should succeed.

When do voting epochs start and end?

Voting epochs run for precisely one week, starting and ending at midnight (0:00 UTC) every Thursday.
