Checking a voucher

A voucher says they ran the guide. Part of that can be checked by anyone, on any node. We ask vouchers to post the vouching cast with selfcast cast, so it is signed by the app key Selfcast added for them. Look the account's keys up:

run

curl -s "http://localhost:3381/v1/signersByFid?fid=FID" | jq '.signers[] | select(.source == "SIGNER_SOURCE_OFFCHAIN")'

A key added by selfcast key add is added without gas, names the account itself as the app (requestFid is the account's own FID), has a ttl of 7776000 seconds (90 days), and has six scopes: casts and their removal, reactions and their removal, follows and unfollows. The vouching cast's signer field should be that key. The test account's key:

run

curl -s "https://crackle.farcaster.xyz:3381/v1/signersByFid?fid=3356360" | jq '.signers[] | select(.source == "SIGNER_SOURCE_OFFCHAIN")'

output
