1.2.1

Released on May 13th, 2026

• fixes for Wallet SDK type inference

a typing issue around optional extend options and SDK initialization was fixed to improve TypeScript inference and reduce false-positive type errors in consumer projects.

• improved compatibility with unknown Canton versions

when a newer/unknown Canton version is detected, the SDK stack now warns and falls back to a compatible client version instead of failing immediately, making forward-compatibility smoother while still surfacing the warning.

• hardened unauthenticated connection error handling

minor exception handling edge cases in unauthenticated connection detection were fixed to avoid misleading failures.
