Bulls On Elysium is an onchain herd economy on Elysium mainnet. It starts with 2,222 Genesis tokens: 1,111 Bulls and 1,111 Cows, pixel art stored fully onchain, and turns them into living assets: they earn, breed, merge, get forged and race.

Every system feeds the same token, $HAY, and every system also burns something. Bulls create value by being held and used, and the herd gets rarer the more people play.
Everything in these docs is the planned design. Numbers may be tuned before each system launches, and every change is announced on X. Nothing here is financial advice.
The herd is split exactly in half: 1,111 Bulls and 1,111 Cows. They share the same 146 traits and the same rarity, so neither side is rarer than the other.
Every trait appears exactly as many times on Cows as on Bulls, and both genders get the same number of each rarity:
| Rarity | Bulls | Cows |
|---|---|---|
| 1/1 Legend | 6 | 6 |
| Legendary | 11 | 11 |
| Epic | 44 | 44 |
| Rare | 110 | 110 |
| Uncommon | 277 | 277 |
| Common | 663 | 663 |
Twelve hand-built 1/1s: six gods (Zeus, Apollo, Ares, Hades, Poseidon, The Elysian King) and six goddesses (Hera, Athena, Aphrodite, Artemis, Demeter, The Elysian Queen).
Breeding and the Merge both need one Bull and one Cow. Holding a pair unlocks the whole economy.
The whole project runs on one loop. Each step makes the next one stronger.
| Generation | How it's made | Supply |
|---|---|---|
| Gen 0 ยท Genesis | The paid mint | 2,222 (only shrinks) |
| Gen 1+ ยท Calves | Breeding two bulls | Up to 4,444, ever |
Genesis bulls are the only ones that can be minted, and they keep perks no calf has: higher breed limit, Genesis airdrop and a stronger vote.
$HAY is the herd's token on Elysium. Bulls produce it; every other system consumes it.
| Earn $HAY | Spend $HAY |
|---|---|
| Grazing (daily) | Breeding a calf |
| Stampede prizes | Merging two bulls |
| Genesis airdrop | Reforging a trait |
| Season rewards | Crafting Relics, Stampede entries |
Full tokenomics are coming soon.
$HAY is a utility token for the herd economy, not an investment. It has no promised monetary value.
Every bull in your wallet grazes $HAY every day. Nothing is staked or locked: your bull never leaves your wallet, and you claim whenever you like.
| Bull | $HAY / day | Ascended |
|---|
Rarity comes from a bull's traits: rare traits are drawn in dark ink, and the more dark slots a bull has, the rarer it ranks.
Calves graze at a reduced rate while they grow, then switch to the full rate for their rarity once adult. See Calves & Growth.
An adult Bull and an adult Cow you own can breed a Calf: a brand new NFT that inherits traits from both parents. Unlike the Merge, both parents stay with you.
| Breed # | Cost per breed |
|---|---|
| 1st | 400 $HAY |
| 2nd | 600 $HAY |
| 3rd | 900 $HAY |
Only 4,444 calves can ever exist. When the cap is reached, breeding closes for good.
A calf grows up while it stays in your wallet. Growth unlocks its utility step by step.
| Stage | Held for | Grazing | Unlocks |
|---|---|---|---|
| ๐ผ Calf | 0 days | 25% of its rate | Grazing, Stampede (junior) |
| ๐ฎ Yearling | 14 days | 60% of its rate | The Forge |
| ๐ Adult | 30 days | Full rate | Breeding, the Merge, full Stampede |
The Merge burns a Bull and a Cow and gives you one stronger one that keeps the rarest trait from every slot. You choose whether it comes out as a Bull or a Cow. It's the fastest way to a rare token, and it permanently shrinks the supply.
Background: Merged Black), so merged NFTs are easy to tell apart on secondary markets.Try it with real bulls in the Merge simulator.
The Forge is the herd's workshop. Spend $HAY and Scrap to change a single trait or craft Relics that boost everything else.
Scrap is the Forge's material. You get it from merges (2 per merge) and from every Stampede race you finish (1 per race). Scrap is an onchain item you can trade.
Reforging re-rolls one trait slot on a bull you own. Use it to chase a dark trait in the one slot holding your bull back from Ascension.
Relics are single-use items crafted in the Forge. They're tradeable, so crafting them is also a way to earn.
| Relic | Effect | Recipe |
|---|---|---|
| ๐ Golden Bell | +25% grazing for 30 days | 500 $HAY + 3 Scrap |
| ๐งช Growth Tonic | Grow a calf one stage instantly | 250 $HAY + 2 Scrap |
| ๐ชถ Fertility Feather | Reset a bull's breeding cooldown | 300 $HAY + 2 Scrap |
| ๐ Lucky Horseshoe | 2ร Rare+ odds on the next reforge | 200 $HAY + 2 Scrap |
| ๐ก๏ธ Stampede Shield | Refund 50% of a lost race entry | 100 $HAY + 1 Scrap |
75% of the $HAY spent crafting relics is burned. New relics are added each season by Council vote.
The Stampede is a weekly race. Enter a bull, and the race is settled onchain from your bull's stats plus a fair random roll.
| Stat | Comes from |
|---|---|
| Power | Horns and Herd |
| Speed | Dress, Ears and Nose |
| Grit | Top, Eyes, Mouth and Marking |
Rarer traits give higher stats, but the random roll means any bull can win on its day.
The endgame. When all 8 trait slots of a bull (Top, Eyes, Mouth, Dress, Horns, Ears, Nose, Marking) are Rare or better, the bull can ascend.
Almost no bull is born ascended. Merge to stack dark traits, reforge the last stubborn slot, or breed and hope for a lucky mutation.
The Council is how holders steer the herd. Proposals cover treasury spending, new Relics, Stampede rules and season rewards.
| Bull | Votes |
|---|---|
| Calf (adult) | 1 |
| Genesis bull | 2 |
| Ascended bull | 3 |
| Legend | 5 |
A proposal passes with a majority of votes cast and a quorum of 10% of all votes.
The full $HAY tokenomics will be published closer to the $HAY launch in Phase 3. Follow @bullsonelysium so you don't miss it.
$HAY is created in one place (grazing) and consumed in many. That balance is what keeps it useful.
| Sink | Cost | Burned |
|---|---|---|
| ๐ฃ Breeding | 400โ900 $HAY | 50% |
| ๐ The Merge | 300 $HAY + a Bull & a Cow | 100% (and 1 token) |
| ๐ฒ Reforging | 150 $HAY + Scrap | 100% |
| ๐บ Relics | 100โ500 $HAY + Scrap | 75% |
| ๐ Stampede | 50 $HAY entry | 10% of the pool |
Genesis is a paid mint of 2,222 bulls on Elysium mainnet. Whitelisted wallets mint first, then the public sale opens.
| Use | Share | What it pays for |
|---|
The treasury is funded by breeding fees and Stampede cuts. The Council votes on how it's spent: liquidity, season rewards, new relics and audits.
Most collections stop at the mint. Bulls On Elysium is built to keep working after it: every bull earns, every system burns, and the herd gets rarer the more it's played.
The roadmap runs in eight phases. Each one unlocks the next, and Genesis holders get every phase first.
Live now.
The quest board opens on X. Follow, like and repost the launch post, then comment your wallet under it and paste the comment link as proof to claim a whitelist spot. Builds the first herd before mint.
2,222 Genesis bulls minted onchain. Whitelist first, then public. Reveal and rarity ranks go live, and grazing starts counting from the mint.
$HAY launches with liquidity seeded from the mint raise. The Genesis airdrop is distributed and every held bull starts claiming daily $HAY with loyalty streaks.
The audited Merge contract opens. Burn a Bull + a Cow + $HAY into 1 stronger one on a black background. Genesis supply starts shrinking and Scrap enters the game.
Breeding opens. Bull + Cow pairs breed the first calves, which grow up in their owners' wallets and join the economy. The 4,444 calf cap starts counting down.
Reforging and Relic crafting go live. Scrap from merges finally has a use, and holders can target the exact traits they need.
Weekly races begin with $HAY prize pools, junior leagues for calves and season leaderboards.
Fully dark bulls ascend into Elysian form, and the Council takes over the treasury and future seasons.
Every bull's art is a tiny SVG (about 4 KB) stored onchain. Calves, merges and reforges are drawn onchain by the same engine, so the herd exists as long as Elysium does.

Only trust contract addresses posted in these docs and on @bullsonelysium.
If someone offers you a "guaranteed" spot, early mint or free $HAY for a fee, it's a scam.
No, Genesis is a paid mint. Price: TBA. The raise launches $HAY and builds the utility.
Both need a Bull and a Cow. Breeding keeps both parents and creates a new calf. The Merge burns the pair and gives you one stronger Bull or Cow.
Calves graze less while they grow and breed fewer times, and they can't get the Genesis airdrop. Once adult, a calf with great traits can still out-graze a common Genesis bull.
Complete the four quests on the quest board and claim with your X handle and wallet.
