eIDAS 2.0 / EUDI Wallet Acceptance

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Attribute attestation mapping > wallet-based KYC flow design > RP registration check > readiness scoring. eIDAS 2.0 (Regulation (EU) 2024/1183).
