EUDI & Business Wallet Developer Debug Tools

iGrant.io provides tools to support developers working with EU Digital Identity (EUDI) Wallets and the European Business Wallet, enabling debugging and testing of interactions between issuers, holders, and verifiers. These tools simplify decoding and validating critical components such as QR codes, JWTs, mdoc CBOR, JSON schemas, and X.509 certificates. They are designed to enhance development efficiency and help ensure compliance with the latest eIDAS 2.0 standards.
