So that I can have an onchain representation of my Stamps and score and qualify for onchain programs

Acceptance Criteria

GIVEN a user with a passport
WHEN they build up a score over 20 and would like to push onchain to multiple networks
THEN they can do so with less effort by selecting multiple chains during the mint onchain process
