marcello pushed a commit to branch master
in repository libeufin.
commit 13bfc9f8d8eca261e515b4004ab6f24a8b50be1e
Author: Marcello Stanisci <address@hidden>
AuthorDate: Wed Apr 29 20:39:14 2020 +0200
Abstracting on "bank account".
Tend to use the triple <iban, bic, holder name>,
instead of the mnemonic label given to bank accounts.
