Describe your feature request

Summary

Requesting addition of the Blocks (B) SIP-010 fungible token to Ledger's
Stacks token support, following the framework merged in #12168 and
LedgerHQ/crypto-icons#70.

This issue is to request the token be added to the crypto-assets-service
backend (CAL). I'm prepared to open a companion icon PR to
LedgerHQ/crypto-icons once the backend entry exists, since the verification
script there checks IDs against the service.

cc @emmanuelm41 @lawRathod @gre-ledger @semeano — apologies for the direct
ping; the public-facing token submission form covers EVM chains only and
Ledger Support directed me to GitHub for SIP-10 requests.

Proposed Ledger ID

About the Token

Blocks is a community memecoin and digital collectible on Stacks. The metadata explicitly discloses memecoin status with no utility or promised returns, in line with similar already-listed tokens (WELSH, MEGA, ROO, NOT, SKULL).

Asset Files

I have a 144×144 PNG icon prepared per the crypto-icons repo guidelines
(opaque background, ~15KB) ready to submit via PR once this entry is added.

Happy to provide additional info — volume figures, holder count, etc. — on request.
