Connect & Mint
Connect your TON wallet and spend GEMSTON to mint your first Stoncat. Each one starts as a unique Paper-rarity cat with basic purrks (traits).

Discover Stoncat
The evolving NFT identity powered by GEMSTON on the TON blockchain. Mint your Stoncat, feed it GEMSTON to roll Purrks, then Dress up to change its look.
How it works
Paper
2
Feed GEMSTON
Spend GEMSTON to roll one Purrk into inventory. Higher amounts improve rare-tier odds and can widen which slots appear. Equip new looks in Dress up.
3
Dress up & Rank up
As you spend more GEMSTON, stage rises and unlocks rarer Purrks. Equip what you roll to climb rarity ranks — inventory alone doesn’t change the look.
Genesis
11 Unique Purrks
Every Stoncat is built from 11 visual layers. Six are always present, five are accessories you can roll and equip. Each purrk has Standard, Premium, Elite, and Mythic tiers.
Rarity & Stages
Rarity
Rarity is calculated from the purrks you currently wear — not random luck. Roll rarer Purrks, then equip them in Dress up to climb the ranks.

FAQ
GEMSTON is a token on the TON blockchain. It powers the Stoncat ecosystem — you spend it to mint Stoncats and roll Purrks. You can buy GEMSTON on STON.fi.
Each feed rolls exactly one purrk into that Stoncat’s inventory. The look does not change until you equip it in Dress up. The amount of GEMSTON you spend determines which slots can appear and the odds of rolling rare tiers. Your cumulative spending determines your evolution stage, which unlocks higher-quality purrk values — see how rarity & stage work.
Yes. Every Stoncat is minted as a real TEP-62 NFT on the TON blockchain. You own it in your wallet, can view it on Tonviewer or GetGems, and it updates visually when you save a new look in Dress up (off-chain metadata).
The website always shows the latest image. Wallets, blockchain explorers (like Tonviewer), and marketplaces cache NFT metadata, so it can take several hours for them to catch up after you save a new look. On GetGems you can try forcing a refresh with the Update metadata control — that often helps, but it can still take a little time.
Yes — rarity follows what you wear. If you equip a lower-tier purrk than before, your rarity score can drop. Rolls themselves don’t change rarity until you equip. With tier-weighted odds, the pool trends toward better options as you spend and stage up. More detail in how rarity & stage work and the full purrks catalog.
