Curve DAO Token (CRV)

Curve DAO Token is based on the ERC-20 token standard as defined at EIP-20.

Contract Source & Deployment

The Curve DAO Token contract is deployed to the Ethereum mainnet at: 0xD533a949740bb3306d119CC777fa900bA034cd52.

Source code is available on Github.

For a broader understanding of the use case of the CRV token, check out Understanding CRV.

Tokenomics¶

The total supply of 3.03 billion is distributed as follows:

62% to community liquidity providers
30% to shareholders (team and investors) with a vesting period of 2-4 years
5% to the community reserve
3% to employees with a 2-year vesting period

The initial supply of approximately 1.3 billion (~43%) is distributed as follows:

5% to pre-CRV liquidity providers with a 1-year vesting
30% to shareholders (team and investors) with a vesting period of 2-4 years
3% to employees with a 2-year vesting period
5% to the community reserve

CRV Emissions¶

Mining parameters are used to determine token emissions, which are based on epochs (one year). With each passing epoch, the rate will be reduced, consequently decreasing the overall CRV emissions.

The rate can be adjusted by invoking the update_mining_parameters() function. Although this function is accessible to anyone, attempts to call it will be reverted if a year has not elapsed since the last update. When successfully executed, the mining_epoch increments by 1, and the start_epoch_time updates to the timestamp of the function call. Furthermore, the update_mining_parameters() function will automatically trigger if someone attempts to mint CRV before a scheduled rate reduction.

The future rate is calculated as follows:

\[\text{rate}_\text{future} = \text{rate}_\text{current} * \frac{10^{18}}{2^{\frac{1}{4}} * 10^{18}}\]

with \(\text{rate}_\text{current}\) fetched from CRV.rate().

Yearly Inflation Reduction

Effectively, each rate reduction decreases CRV inflation by approximately 15.9%.

`mining_epoch`¶

CRV.mining_epoch() -> int128: view

Getter for the current mining epoch. The mining epoch is incremented by 1 every time update_mining_parameters() is successfully called. At deployment, mining_epoch was set to -1.

Returns: mining epoch (int128).

`start_epoch_time`¶

`rate`¶

CRV.rate() -> uint256: view

Getter for the current inflation rate of the CRV token emission. The rate is denominated in emissions per second and has a base of 1e18.

To calculate the CRV emission per day:

\[\text{daily_emission} = \text{rate} * 86400\]

\[\text{weekly_emission} = \text{rate} * 86400 * 7\]

\[\text{yearly_emission} = \text{rate} * 86400 * 365\]

Returns: current inflation rate (uint256).

Source code

rate: public(uint256)

Example

>>> CRV.rate()
5181574864521283150

Calculating Daily Emissions

\(\text{daily_emission} = \frac{5181574864521283150}{10^{18}} * 86400 = 447688.07\)

`update_mining_parameters`¶

update_mining_parameters()

Function to update the mining parameters for the token. By updating, the newly decreased inflation rate is applied. This function is callable by anyone. However, the call will revert if block.timestamp is less than or equal to start_epoch_time + RATE_REDUCTION_TIME, indicating that one year has not yet passed and therefore the rate cannot be updated yet.

Contract Info Methods¶

`avaliable_supply`¶

CRV.avaliably_supply() -> uint256

Getter for the current number of CRV tokens - claimed of unclaimed - in existence.

Returns: currently existing tokens (uint256).

Source code

@internal
@view
def _available_supply() -> uint256:
    return self.start_epoch_supply + (block.timestamp - self.start_epoch_time) * self.rate

@external
@view
def available_supply() -> uint256:
    """
    @notice Current number of tokens in existence (claimed or unclaimed)
    """
    return self._available_supply()

Example

>>> CRV.avaliable_supply()
1953676805157446496269106603

`totalSupply`¶

CRV.totalSupply() -> uint256

Getter for the total number of tokens in existence.

Returns: total supply (uint256).

Source code

@external
@view
def totalSupply() -> uint256:
    """
    @notice Total number of tokens in existence.
    """
    return self.total_supply

Example

>>> CRV.totalSupply()
1950555367872773429287303134

`decimals`¶

CRV.decimals() -> uint256: view

Getter of the decimals of the token.

Returns: decimals (uint256).

Source code

decimals: public(uint256)

@external
def __init__(_name: String[64], _symbol: String[32], _decimals: uint256):
    """
    @notice Contract constructor
    @param _name Token full name
    @param _symbol Token symbol
    @param _decimals Number of decimals for token
    """
    ...

    self.decimals = _decimals

    ...

Example

>>> CRV.decimals()
18

`balanceOf`¶

CRV.balanceOf(arg0: address) -> address: view

Getter for the crv token balance of a specific address.

Returns: balance (uint256).

Input	Type	Description
`arg0`	`address`	wallet to check CRV balance for

Source code

balanceOf: public(HashMap[address, uint256])

Example

>>> CRV.balanceOf('0xd061D61a4d941c39E5453435B6345Dc261C2fcE0')
2187980063734121847368

Although set_minter is technically an admin-guarded function, there is no actual way to change the minter address because the code checks if the current minter is set to ZERO_ADDRESS, which was only true when the contract was initially deployed. ↩
