The release story
Maker statements and surviving thread evidence, organized as one continuous record.
Funded versus unfunded Monero brass
Buyer supplies the XMR
Smoothie provided the coin addresses; the buyer, not the maker, supplied the 5 XMR face value.
Unfunded marking
Coins shipped empty were visibly marked “UNFUNDED” on the hologram. They received the address and private view key but no digital funding certificate.
What the certificate proved
Funded pieces received a PGP-signed digital certificate containing key-image signatures. Smoothie stressed that a view key alone cannot prove that outputs remain unspent.
Tamper evidence, not proof
The maker noted that holograms are tamper-evident rather than tamper-proof and explained that a secondary buyer still had to validate the address, key images, and chain state.
Serialization and distribution
Five-thousand maximum
The stated maximum of 5,000 already includes the 1,000 giveaway pieces; the giveaway is not an additional mintage.
Serial scheme
The published sequence runs 0–999 and then letter-number blocks such as A00–A99, B00–B99, continuing through the alphabet.
Random assignment
Smoothie said serials were randomly selected. Specific numbers were reserved for auctions rather than normal orders.
Roll splitting
Two buyers could split a roll and pay separately, but the maker asked to deal with one coordinator and ship to one address.
Archival notes
- The giveaway allocation is included in the stated 5,000 maximum.
