TSP
A TSP is a technical service provider a PSP can outsource digital euro work to. The PSP keeps full regulatory responsibility.
Definition
TSP
Also written as: technical service provider
A TSP is how a PSP that does not want to build a digital euro stack from scratch gets one anyway.
What it is
PSPs may outsource digital euro development and operations to third-party providers. The provider doing that work is a technical service provider.
This is not an exotic arrangement. It is the same shape as the outsourcing that already exists throughout European payments — core banking, card processing, PSD2 interfaces. The digital euro does not introduce a new legal concept here; it inherits an established one.
The line that does not move
The PSP retains regulatory responsibility. You can outsource the build, the run, the on-call rotation and the release process. You cannot outsource being the regulated entity.
That single sentence should govern how a PSP evaluates a TSP. The questions that matter are not just "can they build it?" but "can I supervise, audit and evidence what they built, to my regulator, when asked?"
Why the TSP model exists at all
Look at the shape of the obligation. Credit institutions will be obliged to offer basic digital euro services on request once the digital euro launches, and those basic services are free for individuals.
That combination — mandatory to offer, no revenue from the basic service — is unusual. It means every credit institution in the euro area needs an integration, including institutions with no appetite to run a payments engineering team. For a small or mid-size bank, a compliance obligation that generates no fee income is precisely the kind of thing you buy rather than build.
Build vs buy is a real decision
It is not automatic that buying wins. We walk through the trade-off in Build vs buy: the digital euro integration decision for small PSPs.

Alias
An alias is a pseudonymous identifier — such as a phone number — standing in for a digital euro account, so you can be paid without revealing your DEAN.
