Digital pets that live on the chain — true NFTs you own, name, feed, train, battle and trade. Adopt an egg for 1 NADO; a future block hash nobody can predict decides which of 100 animals hatches — dogs, cats, turtles, fish, bugs, octopuses, monkeys… 70 common, 25 rare and 5 legendary (Dragon, Phoenix, Kraken, Unicorn, Star Whale), with 10 stats locked at hatch. Pets eat real NADO to stay alive — stop feeding and they die (a full belly lasts 30 days). Train them (rarer = easier), then challenge other pets to turn-based duels for stakes where every stat fights — the winner takes the pot and claims the losing pet, though the loser has a small 10% chance to die; both fighters are exhausted for 6 hours after. Sell and buy pets on the built-in marketplace. Everything — genes, species, coats, meals, training rolls, fights, sales — is decided and recorded on-chain.
Your key never touches this page — signing happens in your wallet at get.nadochain.com, then you bounce back.
A pet's gene is HASH(blockhash(b) ‖ blockhash(b+1) ‖ petId) where block b is minted after you sign — nobody (including us) can pick or predict it. The gene fixes the animal (gene % 100 picks one of the 100 species), its rarity tier, coat and all 10 base stats forever. Training and battles bind to future block hashes the same way; the contract recomputes every roll on-chain, so the result you see is the result everyone's node computes. Adoption, food and training fees are burned — paid to a dead key no wallet can ever control — so playing shrinks the supply; there is no house wallet. Ownership is a plain on-chain record: transfer it and the pet is theirs, key and kibble.
