Factory
The Factory is used to deploy any PrincipalToken and Curve pools permissionlessly.
Factory.sol code can be found on GitHub.
Methods
deployPT
Deploys the PrincipalToken contract implementation.
See also PrincipalToken.
_ibt
address
duration
uint256
The duration of the pt
pt
address
deployCurvePool
Deploy a curve pool for the specific _pt
instance with the specified curvePoolParams
_ibt
address
curvePoolParams
The parameters of the curve pool to be deployed
curvePoolAddr
address
The address of the curve pool that was deployed
CurvePoolParams
The curve pool parameters as defined in the curve pool documentation is a struct that hold the curve pool parameters.
A
uint256
Amplification Parameter [4,000 to 4,000,000,000] Larger values of A make the curve better resemble a straight line in the center (when pool is near balance). Highly volatile assets should use a lower value, while assets that are closer together may be best with a higher value.
gamma
uint256
The gamma parameter can further adjust the shape of the curve. Default values recommend .000145 for volatile assets and .0001 for less volatile assets.
mid_fee
uint256
[.005% to 1%] Percentage. Fee when the pool is maximally balanced. This is the minimum fee. The fee is calculated as mid_fee * f + out_fee * (10^18 - f)
out_fee
uint256
[Mid Fee to 1%] Fee when the pool is imbalanced. Must be larger than the Mid Fee and represents the maximum fee.
allowed_extra_profit
uint256
[0 to .01] As the pool takes profit, the allowed extra profit parameter allows for greater values. Recommended 0.000002 for volatile assets and 0.00000001 for less volatile assets.
fee_gamma
uint256
[0 to 1] Adjusts how fast the fee increases from Mid Fee to Out Fee. Lower values cause fees to increase faster with imbalance. Recommended value of .0023 for volatile assets and .005 for less volatile assets.
adjustment_step
uint256
[0 to 1] As the pool rebalances, it will must do so in units larger than the adjustment step size. Volatile assets are suggested to use larger values (0.000146), while less volatile assets do not move as frequently and may use smaller step sizes (default 0.0000055)
admin_fee
uint256
ma_half_time
uint256
[0 to 604,800] In seconds -- the price oracle uses an exponential moving average to dampen the effect of changes. This parameter adjusts the half life used.
initial_price
uint256
The price of coin0 with respect to coin1. This price set the initial liquidity concentration
deployAll
Deploy a Principal Token, a curve pool and a LP Vault associated with the PT and the deployed curve pool in a single transaction.
_ibt
address
_duration
uint256
curvePoolParams

pt
address
curvePoolAddr
address
The address of the curve pool that was deployed
lpv
address
The address of the LP Vault that was deployed
