# The DAO Pool
The API3 DAO has a single staking pool called the DAO pool. Staking API3 tokens in the pool will grant representation and staking rewards, but at the same time, the staked tokens will be used as collateral to pay out coverage service claims as needed. To do this, the pool focuses on three token utilities and implements a coverage service which by design balances rewards and risks through responsible governance.
API3 is the native token of the API3 project. The API3 ecosystem is a single token environment. Check out the Medium post API3 Tokenomics Update (opens new window) for an in-depth overview on API3 tokenomics.
# Unstaked Tokens
Unstaked tokens are simply owned by an entity and do not generate revenue or have voting rights. They are subject to market value and inflation.
# Staked Tokens
Staked API3 tokens are used as collateral for the on-chain coverage service that will provide quantifiable and trustless security guarantees to dAPI users. These mechanics will remove the need for a central authority at the ecosystem level.
Staking simply means you are placing API3 tokens into the DAO pool. When staking tokens to the DAO pool you gain access to weekly staking rewards but also share in the risk of the coverage service. You are also granted voting rights on active DAO proposals and inflationary rewards.
To stake your tokens see StakingTokens. You can stake as many times as you’d like. Your percentage of all the tokens in the DAO pool are directly related to your percentage of the rewards and the risks. If you stake 10% of the pool you earn 10% of rewards and will pay 10% of coverage service claims.
# Token Utilities
Decentralized governance requires well-balanced incentive mechanisms that accurately model both positive and negative outcomes. In other words, the governing entities should be rewarded for good results and penalized for bad ones. The API3 token is designed to facilitate this through three main utilities:
Main utilities of the API3 token.
Note that it is critical for these three utilities to coincide. All governing entities must receive staking rewards for them to govern in a way that maximizes revenue. All governing entities must have their funds used as collateral for them to govern in a way that minimizes security risks. "Security" refers to a "guarantee or reliability of dAPI service"
Reference section 5.4 "API3 Tokenomics" of the API3 whitepaper.
The staking utility incentivizes participation in the DAO and alignment of incentives. By staking your API3 tokens into the DAO pool, you receive governance voting rights and take part in providing API3 users with quantifiable security in the form of the coverage service. The DAO pool also grants you inflationary rewards and exposes you to the risk of coverage service claims.
Staked tokens in the DAO pool grant governance voting rights, inflationary rewards and are used to fund the coverage service which exposes staked tokens to the risks of coverage service claims.
- Generate shares (tokens) in the DAO through revenue sharing from the coverage service fees.
- Generates inflationary rewards by decreasing the circulating supply of API3 tokens through revenue burn from the coverage service fees.
- Improved token inflation protection compared to unstaked tokens.
- Voting privileges on DAO proposals.
- Staked tokens in the DAO pool are used to cover potential financial losses from dAPI malfunctions that the dAPI consumer might incur.
To stake your tokens use the Dashboard. You can stake as many times as you’d like. Your percentage of all the tokens in the DAO pool are directly related to your percentage of the rewards and the risks. If you stake 10% of the pool you earn 10% of rewards and will pay 10% of coverage service claims.
The collateral utility has the participants share the DAO's operational risk and incentivizes them to minimize it.
If staking tokens only yielded rewards, the sole governance incentive would be to maximize the revenue. This would be done by increasing the number of dAPI users aggressively, and the amount that is secured by the dAPIs with it. Doing so puts excessive pressure on a dAPI which is more likely to malfunction due to an attack. Therefore, this is not a sustainable governance strategy for decentralized data feeds.
Exposing the governing parties to the risk would align their incentives with that of the DAO. The governing parties need to be penalized when a dAPI malfunction occurs using an onchain coverage service that provides dAPI users with quantifiable and trustless security guarantees. The Coverage Service uses staked tokens of the DAO pool as collateral, which means that when a dAPI malfunction is confirmed through the dispute resolution protocol, user damages will be covered from the pool's staked tokens.
Reference section 5.4.2 "Collateral" of the API3 whitepaper.
The governance utility gives the participants the ability to enact and manage staking and collateral.
The only way to gain representation in the DAO is to stake API3 tokens in the pool. Staked tokens give their holders the right to take part in the governance of the API3 ecosystem through the DAO. To vote token holders must stake their API3 tokens in the pool, which also gives them access to weekly staking rewards but also share in the risk of the coverage service.
All governing parties will be exposed to all risks and rewards of API3, and will govern to optimize them. Inflationary rewards and the staked tokens being used as collateral will create a positive feedback loop in terms of governance quality. Initial token holders will have to stake and expose themselves to risk if they do not want to lose value to inflation. If they misgovern and lose collateral through coverage service claims, these tokens will get returned to the open market, from where they will be acquired by new governing parties. In contrast, if initial token holders govern well and cause token scarcity in the market, the representation distribution will be protected. In other words, governance tokens being used as collateral results in a robust Darwinian structure that improves itself and is able to recover from failures.
In general the industry standard for API provider subscription fees are commonly paid monthly or annually, as this scheme suits both API providers and their clients. API3 follows the same scheme for dAPIs.
# dAPI monetization
To gain access to a dAPI, a dApp will pay a recurring subscription fee, which may be fixed or customized for the dApp based on a specific use case. These prices will be determined by the respective team, and will include a premium if the dApp wants to receive the Coverage Service. The payment can be made in any cryptocurrency, which will be received by the DAO in API3 tokens through a liquidity pool-based decentralized exchange.
# API provider compensation
API providers will be compensated periodically at fixed rates, which will fit their existing pricing models. This will be done using stable coins wherever possible, some API providers categorically reject handling cryptocurrency as payment. In such cases, the DAO will provide a grant that will be paid out in return of the proof that the API provider is compensated in fiat by the grantee.
API3 aims to set up, maintain, and monetize dAPIs at scale. Its success in doing so can be estimated by its total revenue, as this will increase with the number of dAPIs and the amount of funds secured by them. API3 generates revenue through subscription fees and coverage service fees. The fees can be made in any cryptocurrency, which will be received by the DAO in API3 tokens through a liquidity pool-based decentralized exchange. To align the governance incentives with API3’s success, combined with the inflationary rewards, the net revenue to the DAO will result in burning of API3 tokens. This mechanic will produce positive staking incentives using inflationary rewards and claim risks rather than revenue sharing.
Fees from revenue are burned. Inflationary rewards are distributed by the DAO. Coverage service claims are paid to dAPI covered entities from the pool of staked tokens.
# Earning Rewards
Earning rewards is simple: everyone who owns shares of the DAO pool (everyone who has staked API3 tokens into the DAO pool contract) will earn rewards as they are added to the DAO pool. When you schedule tokens to be unstaked, you stop earning rewards for those tokens.
Remember that when you stake, you receive non-transferable pool shares equal to the current total number of issued shares divided by the total number of tokens staked. Since the reward adds additional tokens to the pool, the "price" for one share will not always be one token.
# Inflationary Rewards
In essence, inflationary rewards force token holders to stake and preserve the value of their tokens. However, staking is risky due to the funds being used as collateral for the Coverage Service, and forces the staker to participate in governance to ensure that the risk is minimized. As a combination of the two, an inflationary governance token used as collateral forces all token holders to participate in governance, which is ideal because it maximizes the decentralization of governance. Inflationary rewards are paid weekly by an implicit and automatic process through an on-chain contract. Furthermore, inflationary rewards are vested for a year, which results in governing parties sharing the project’s long term interests.
# Reward Calculation And Distribution
The staking reward will float to have the total staked amount reach equilibrium at the target. In other words, the staking reward will increase while the staked amount is below the target, and vice versa. It will not have a pre-determined schedule.
Reward amount is represented as APR (annual percentage rate). You can derive APY (annual percentage yield) using an online calculator (opens new window). There is a governable "APR update step", which is the step size each week the APR will be updated with. Also there are governable minimum and maximum APR values, but these (especially maximum APR) are there as safety measures and should not affect rewards in day-to-day operation. In general, governing the stake target will be the primary tool for regulating rewards.
Rewards are added as staked API3 tokens into the DAO pool each time the
mintReward function is called.
mintReward is callable by anyone, once per
"epoch" (and single epoch length is 1 week). When it is called, an amount of
API3 tokens is minted and added to the DAO pool:
rewardAmount = totalStakedTokens * APR * epochLengthInSeconds / yearInSeconds / 100
(see the smart contract source (opens new window) for more information).
In addition, each time
mintReward is called, the annual percentage (the reward
rate) is updated up or down by the APR update step size (1%), according to
whether the total number of staked tokens is above or below its target. The
initial target is 50%, so if the total number of staked tokens is less than 50%
of the total token supply when
mintReward is called, APR will be raised by 1%
for the next reward payout (and vice versa). Thus, APR will constantly be
adjusted, but it will always stay between a designated maximum and minimum.
Rewards Distribution User X stakes 600 tokens and user Y stakes 400, so there is a 60% (X) 40% (Y) split ownership in the 1000 token DAO pool. For a particular week the reward payout is 1% (10 total tokens) and the pool is now 1010 tokens. X at 60% now has 606 tokens and Y has 404. Remember that the 10 reward tokens will not vest for a period of one year.
# Reward Withdrawal
Rewards withdrawals are baked into default withdrawals, except that rewards are locked for 1 year after minting. As a staker, your pool shares will always reflect a proportional right to the pool of staked tokens, including any rewards that have been minted. When you unstake and withdraw your tokens, you will receive:
- your tokens,
- plus any share of the rewards you earned,
- minus rewards that were added to the pool within the last year, which will remain staked.
To summarize reward withdrawal: you will not be able to withdraw your rewards for a year. Since rewards get paid out every week, you can think of this as a rolling unlock (the rewards you receive this week will get unlocked 1 year later, the rewards you will receive next week will get unlocked 1 year 1 week later, etc.) This 1 year-lock is the secret sauce to good decentralized governance, it essentially aligns the incentives of the stakers/governors with the ones of the DAO/project/token for a whole year.
# Coverage Service
Please note Coverage Service products are not implemented yet.
Before they are, a proposal with a 50% quorum requirement will have to be passed for them to go active
API3 provides dAPI users with a quantifiable level of security in the form of an on-chain coverage service. Staked tokens in the DAO pool are used to cover potential financial losses from dAPI malfunctions that the dAPI consumer might incur. This accomplishes two goals.
- The coverage service acts as a well-defined and trustless safety net in case of a dAPI malfunction.
- It holds the governing parties responsible for dAPI malfunctions, and thus incentivizes them to govern towards more secure dAPIs.
API3 co-developed an on-chain coverage service with Kleros that provides quantifiable and trustless security to dAPI users. This coverage service will protect the dAPI user against damages caused by certain dAPI malfunctions up to a payout limit. Note that even if API3 did not provide this service, the dAPI user could have received on-chain coverage services using a third party solution. Such a solution would tend towards charging very high coverage service premiums, as they would not have access to the information and expertise to accurately assess dAPI risks.
The proposed coverage service is special in the way that it is collateralized by the funds staked by the governing parties of the API3 DAO into the DAO pool. Therefore, it not only provides security to the dAPI user, but also creates a very strong incentive for dAPIs to be governed in a way that dAPI security is maximized, which will further decrease coverage service costs.
# Claim Risks
The staked tokens in the pool are used as collateral for coverage service claims. Any payout results in the reduction of the total token count in the pool. The reduction is charged against each entity's percentage of tokens in the pool.
Claim Risks User X and Y both stake 500 API3 tokens, so each has 50% ownership in a 1000 token DAO pool. There is a coverage service claim payout of 3.4 tokens and the pool is now 996.6 tokens. X and Y now own 498.3 tokens each based on their 50% ownership.
To insure against potential system failures, the DAO pool can empower special
ClaimsManager contracts to withdraw staked tokens directly. Approved
ClaimsManager contracts do this by calling
payOutClaim(address recipient, uint256 amount) in the DAO pool contract, which
transfers tokens from the DAO pool to the recipient. When this occurs, the total
number of staked tokens goes down, and pool share value goes down in turn.
