Is this stuff using the BRC98/99 semantics like BTMS does, at the wallet layer? Or is this operating above that and just reserving the basket name for the application layer? |
Spell out that bare 1-sat tip moves are shared with collectables, so chain scan must not auto-file them into basket 1sat, and FT lineage must not paint as NFT. Documents old-client misfile / burn risk. Co-authored-by: Cursor <cursoragent@cursor.com>
