Fund the fee reserve
Which address to fund, and why SOL and QSELx are not interchangeable.
After you create a vault, the checklist asks you to fund the fee reserve. Open that step and copy the address it shows. Send the token the app is charging in right now.
Production fees are charged in QSELx from that reserve. SOL sitting in the same address does not satisfy a QSELx charge. If the app is in a SOL fee mode, the reverse is true: QSELx will not cover a SOL debit.
The first LinkingNFT mint is paid for by the company gas wallet, but the mint still checks that your reserve is funded, because the next login session is a paid debit. If the mint says the reserve is not funded, the reserve address does not hold enough of the fee token. The company wallet is not the address you fund.
