Function: _create(TokenType tokenType, uint256 depositAmount, uint256 minAmount, address onBehalfOf)

This function is used to create bond or leverage tokens by depositing reserve tokens. It is internal and is called by the create function. The function calculates the amount of new tokens to create based on the current pool state and oracle price.

Inputs

• tokenType

  • Control: From the create function.

  • Constraints: Bond or leverage token.

  • Impact: Type of token to create.

• depositAmount

  • Control: From the create function.

  • Constraints: None.

  • Impact: The amount of reserve tokens to deposit.

• minAmount

  • Control: From the create function.

  • Constraints: None.

  • Impact: The minimum amount of output tokens to receive.

• onBehalfOf

  • Control: From the create function.

  • Constraints: None.

  • Impact: Address to receive the new tokens.

Branches and code coverage

Intended branches

• Invoke the simulateCreate function.

  Test coverage

• Check the return value of the simulateCreate function to check if the amount is higher than the minimum amount.

  Test coverage

• Mint new tokens.

  Test coverage

• Transfer reserve tokens to the contract from the caller.

  Test coverage

Negative behavior

• Revert if the amount is lower than the minimum amount.

  Negative test

• Revert if the amount is zero.
