SmartMetal series: 2024 and the Limited Edition Azure Dragon

A series is a group of SmartMetal tokens that share one metadata folder on IPFS. The token contract, 0x4516a5D613C30A36D157d3b579813734cbb929a4, had two on 13 Oct 2026 (seriesCount() returns 2), and totalSupply() returns 6,582, the two series added together. Every token in both is non-fungible: totalSupply(id) is 1 for each id.

Series	Series id	Metadata folder (CID)	Token ids	Created on chain
2024	0x2ee2…939a	QmU8oEWK3KNrJqHGtWgpZzjcUBukmSLutFY6ZxGGkcEdLf	1 to 6566 (6,566 tokens)	22 May 2025, block 30,569,486
Veri SmartMetal Limited Edition Azure Dragon	0x2d3e…b9d6	QmSijK1oR1TAGhGeeZrrVrjEoQAyGYGB1Vph3qvSSzT3Ht	16 ids, 7777 to 88888888888 (listed below)	28 May 2026, block 46,583,469

The same table is in /facts.json under series, with the full series ids.

How a series id is made#

createSeries(cid, isFungible) sets the series id to keccak256 of the CID string, exactly as written, so anyone can compute it offline:

# keccak256("QmSijK1oR1TAGhGeeZrrVrjEoQAyGYGB1Vph3qvSSzT3Ht") = 0x2d3e0395c9e91e036ad74f6010443210c6a13260c88e93fc7c2fecc2d577b9d6
node -e 'const {keccak_256}=require("@noble/hashes/sha3.js");const {bytesToHex,utf8ToBytes}=require("@noble/hashes/utils.js");console.log("0x"+bytesToHex(keccak_256(utf8ToBytes("QmSijK1oR1TAGhGeeZrrVrjEoQAyGYGB1Vph3qvSSzT3Ht"))))'

# or, with Foundry's cast
cast keccak QmSijK1oR1TAGhGeeZrrVrjEoQAyGYGB1Vph3qvSSzT3Ht

The hash equals the seriesId topic of the series’ SeriesCreated log, and listSeries returns the same pairs of id and CID. Because the id is the hash of the CID, the same metadata folder gets the same series id on any chain, and createSeries refuses a CID that was already registered.

The 2024 series#

“2024” is the label the tokens carry: each one is named Veri SmartMetal Silver Round #<id> and its metadata has year: 2024. It is not a date. On chain, the series was created on 22 May 2025 at 15:38:39 UTC in block 30,569,486 (transaction), 53 blocks after the token contract itself, and its 6,566 tokens were minted over the following quarter of an hour:

• Ids 1 to 6566 were registered with SeriesActivation first, 100 per transaction, in 66 transactions between blocks 30,569,508 and 30,569,699.
• They were then minted to SeriesActivation (0x412E962bbAE0bB97CE98e74f3424543651a21ce3), again 100 per transaction, from block 30,569,702 (ids 1 to 100) to block 30,569,892 (ids 6501 to 6566). Each mint emitted one URI event per token, one TransferBatch and one SeriesTokensMinted.

seriesTokenCount returns 6,566 and seriesTokens lists the ids 1, 2, 3 … 6566 with no gaps. Id 6567 does not exist (exists(6567) is false).

Every 2024 token shares one image, ipfs://QmYsiGSYWx6mn3TgLZfoZVRqqNjuyvTLziWscfjme3tmAK, and the same attributes apart from its serial number: metal Silver, purity 0.999, weight 1 oz, year 2024, mint Veritaseum, serial number equal to the token id.

Veri SmartMetal Limited Edition Azure Dragon#

The second series was created on 28 May 2026 at 08:18:05 UTC in block 46,583,469 (transaction). Its 16 holders were registered three blocks later (transaction) and the 16 tokens were minted to SeriesActivation in block 46,583,475 (transaction), twelve seconds after the series was created.

The token ids are the repdigits of 7 and 8 from four to eleven digits long:

Length	Ids
4	7777, 8888
5	77777, 88888
6	777777, 888888
7	7777777, 8888888
8	77777777, 88888888
9	777777777, 888888888
10	7777777777, 8888888888
11	77777777777, 88888888888

Each token is named Veri SmartMetal Limited Edition Azure Dragon #<id>, described as “The Azure Dragon of Ancient Chinese Mythology”, with its own image (token 7777’s is ipfs://QmR2coRJYva1ACFU3gMzZRX2LaZztWTFcPrDKvG3FimH6S) and the attributes metal Silver, purity 0.999, weight 1 oz, year 2026, mint Veritaseum, serial number equal to the token id.
