ISlpManager Interface

The ISlpManager interface defines the functions available in the SlpManager contract, which manages the Staked Liquidity Provider (SLP) token system for the Satoshi Perps protocol.

​
Liquidity Management

function addLiquidity(
    address _token,
    uint256 _amount,
    uint256 _minSlp,
    uint256 _minToken
) external returns (uint256);
Adds liquidity to the protocol and mints SLP tokens. 
function removeLiquidity(
    address _tokenOut,
    uint256 _slpAmount,
    uint256 _minOut,
    address _receiver
) external returns (uint256);
Burns SLP tokens and returns the underlying assets.

​
AUM and Price Calculation

function getAum(bool _maximise) external view returns (uint256);
Calculates the total Assets Under Management (AUM) of the protocol. 
function getAumInToken(bool _maximise) external view returns (uint256);
Calculates the AUM in terms of the pool token. 
function getSlpPrice(bool _maximise) external view returns (uint256);
Calculates the price of SLP tokens based on the AUM and total supply.

​
Fee and AUM Management

function setCooldownDuration(uint256 _cooldownDuration) external;
Sets the cooldown duration for SLP token redemptions. 
function setAumAdjustment(uint256 _aumAddition, uint256 _aumDeduction) external;
Sets adjustments to the AUM calculation for accurate pricing.

​
State Access

function cooldownDuration() external view returns (uint256);
Returns the cooldown duration for SLP token redemptions. 
function aumAddition() external view returns (uint256);
Returns the amount added to the AUM calculation. 
function aumDeduction() external view returns (uint256);
Returns the amount deducted from the AUM calculation. 
function slp() external view returns (address);
Returns the address of the SLP token. 
function vault() external view returns (address);
Returns the address of the Vault contract.

​
Usage Notes

  • The SlpManager acts as the minting and burning authority for SLP tokens.
  • Liquidity providers receive SLP tokens representing their share of the pool.
  • SLP tokens accrue value as the protocol earns fees.
  • Withdrawals are subject to a cooldown period to prevent flash loan attacks.
  • The AUM calculation determines the value backing SLP tokens, including assets in the Vault and any adjustments.

​
Security Considerations

  • The cooldown period protects the protocol from potential flash loan exploits.
  • AUM adjustments should be used carefully as they directly affect the price of SLP tokens.
  • Minimum output values protect users from slippage during liquidity operations.
