2 years ago Not sure what this is about. Here is the info in the contract:
// About swap fees on joins and exits:
// Any join or exit that is not perfectly balanced (e.g. all single token joins or exits) is mathematically
// equivalent to a perfectly balanced join or exit followed by a series of swaps. Since these swaps would charge
// swap fees, it follows that (some) joins and exits should as well.
// On these operations, we split the token amounts in 'taxable' and 'non-taxable' portions, where the 'taxable' part
// is the one to which swap fees are applied.
// Invariant is used to collect protocol swap fees by comparing its value between two times.
// So we can round always to the same direction. It is also used to initiate the BPT amount
// and, because there is a minimum BPT, we round down the invariant.
function _calculateInvariant(uint256[] memory normalizedWeights, uint256[] memory balances)
internal
pure
returns (uint256 invariant)
{
/**********************************************************************************************
// invariant _____ //
// wi = weight index i | | wi //
// bi = balance index i | | bi ^ = i //
// i = invariant //
**********************************************************************************************/
invariant = FixedPoint.ONE;
for (uint256 i = 0; i < normalizedWeights.length; i++) {
invariant = invariant.mulDown(balances[i].powDown(normalizedWeights[i]));
}
_require(invariant > 0, Errors.ZERO_INVARIANT);
}
I was able to create an LBP on Rinkeby using 10 DAI as project token and 0 WETH for funding token.
However when I try to fund and initiliaze the LBP via admin panel I am receiving Zero Variant error message
