But currently, it returns the deltaB from the C.BEAN_ETH_WELL pool.

/**
* @notice Returns the total Delta B across all whitelisted minting liquidity Wells.
*/
function totalDeltaB() external view returns (int256 deltaB) {
// @audit wrong token here. should be wseth, check whether it was submitted before.
deltaB = LibWellMinting.check(C.BEAN_ETH_WELL);
}

Impact

function totalDeltaB() external view returns (int256 deltaB) {
- deltaB = LibWellMinting.check(C.BEAN_ETH_WELL);
+ address[] memory tokens = LibWhitelistedTokens.getWhitelistedWellLpTokens();
+ for (uint256 i = 0; i < tokens.length; i++) {
+ deltaB = deltaB.add(LibWellMinting.check(tokens[i]));
