How NFT Minting Works in Soltokemons

Soltokemons keeps two NFT systems side by side, and they do not overlap. Knowing which one you are dealing with avoids almost every point of confusion.

The first is the creature NFT mint. Some wild creatures spawn as a rare mintable variant. You catch them normally, and only later can you choose to mint one into a real on-chain 1/1 collectible. This is paid in SOL and needs a connected Solana wallet.

The second is the Genesis collection. These are the four mascot NFTs minted on the /mint page with the $STKM token, and they behave differently in-game: a claimed Genesis NFT can be fielded in battle. Everything below covers the creature mint first, then Genesis.

As you explore, the server rolls a small chance for a wild creature to spawn as a mintable variant. There are three tiers, in rising rarity: ◈ NFT (the common tier, around 1 in 500 wilds), 💠 Holo (the rare tier, around 1 in 1000), and the much rarer ✨ Shining (the ultra tier).

You catch a variant exactly like any other wild creature - weaken it, then use a Capture Net. There is nothing extra to do in the moment; the tier is decided when the creature spawns and travels with it when you catch it. A Shining is a tougher catch on purpose, so finding one does not guarantee keeping it.

The four Genesis mascots (the base Electric, Fire, Grass and Water creatures - Sparkmon, Pyromon, Floramon and Aquamon) never roll as ◈ NFT or 💠 Holo. Only their Shining form is mintable, which keeps the Genesis sale collection distinct from the creature mint.

This is the part players get wrong most often, so it is worth being blunt about. A caught variant is NOT an NFT. It is mintable. It lives in your collection as an ordinary caught creature that happens to carry a tier badge, and it has nothing on-chain until you decide to mint it.

In the Bag, caught variants are grouped under a Special filter so they are easy to find, each showing its tier badge (◈, 💠 or ✨). That Special group is deliberately separate from the NFT tab, which only shows creatures you have actually minted on-chain.

In short: catching a Holo gives you a Special creature that you may mint later. It does not give you an NFT. Until you run the mint, nothing exists on the Solana blockchain.

When you want to turn a caught variant into a real on-chain collectible, open it in the Bag and use Mint as NFT, which takes you through the Mint panel. The mint is live now. It costs about 0.10 SOL and requires a connected Solana wallet.

On top of the SOL fee, minting also consumes some gathered materials, so the NFT is earned by playing and not purely bought. The materials are the upgrade materials that drop from wild wins, with a tier-appropriate amount depending on the variant. The Mint panel shows what you have and what you need.

The mint is server-authoritative. The server recomputes the creature's tier from its spawn-rolled tag and assigns the provenance tier accordingly: a ◈ NFT mints at common, a 💠 Holo at rare, and a ✨ Shining at ultra (the gilded Shining art and name). The client can never claim a higher tier than the creature actually earned.

One trade-off to know: minting consumes the caught creature. It moves out of your normal collection and becomes an on-chain NFT (it then appears under the Bag's NFT tab as a minted creature). If a mint payment lands but the on-chain mint fails, the server restores the creature.

Since July 2026, every creature NFT is globally unique. For each species there are exactly three mintable slots - one ◈ Common, one 💠 Holo and one ✨ Shining - shared across ALL players. Once someone mints a pair, that exact NFT can never be minted again, by anyone. No reprints, no second editions, ever.

The game enforces this everywhere. Wild variants only spawn for pairs that are still unminted, the Bag and the Mint panel tell you whether your copy's slot is still free ('Not yet minted - be the first') or already gone ('Already minted by another trainer'), and the mint itself refuses - with a full refund - if someone beats you to the slot by seconds.

If another trainer minted your species' slot first, your caught copy keeps its badge and its special look and still fights like any creature - it just can no longer become an NFT. The scarcity is the point: whoever mints first owns that piece of the collection forever.

The Genesis collection is the separate, fixed-edition set of mascot NFTs. You mint these on the /mint page, paid with the $STKM token rather than SOL. This is the public-sale collection and the canonical Genesis edition; there are no reprints.

Genesis NFTs differ from minted variants in one important way: a claimed Genesis NFT can be fielded in battle. Fielding is opt-in, so an NFT only enters your team if you choose to add it.

A fielded Genesis NFT levels per-instance (the specific NFT carries its own level), and its on-chain ownership is re-verified at the start of each battle. That keeps fielding honest - you must still own the NFT to bring it into a fight.

No. The entire core game - exploring, catching creatures, battling trainers and bosses, and finishing the story to free Solana City - is free to play with no wallet and no crypto. Both NFT systems are strictly optional and sit on top of the game.

If you want to collect, the natural path is: play, catch a rare variant when one spawns, and mint it if and when you feel like it. The mint is there when you want it, not a gate on progress.
