SEPA Instant Credit Transfer allows instant sepa transfers, and soon all transactions will be required to be ict if possible. Banks have APIs you can integrate with, which e.g. KDE's money app used to support in the past. The actual underlying transaction system is extremely well designed and reliable, it's just missing the nice APIs that other payment systems have.
