Guild Wars 2

I have a guildie that purchased a new account primarily for buying, selling, trading and storage. Now that they have a sizable amount of gold on the account they can’t trade it or deposit it to the guild vault to complete a trade for a legendary precursor from me. How do we work around this issue?

Level up a character from that account.

A third account is essentially a third player, in the eyes of ANet.

Find a trusted middleman for the trade, or one of you has to go first. There really isn’t another option.
