IBreeds

A breed is a temperament and a strategy. Every horse carries a genome (size fraction, leverage, cooldown, max positions, obedience modifier) that starts at the breed default and is blended on breeding.

IICare

Energy decays 0.4 a minute, mood 0.3. Under 15 energy a horse does not trade. Under 18 mood it closes everything. Feed (+30 energy, 5 min cooldown), pet (+20 mood, +1 tame, 2 min), train (+6 tame, +4 discipline, −10 energy, 10 min), scold (+10 discipline, −12 mood, +2 tame, 5 min). Discipline of 60 or more caps leverage at 2x; under 30 allows 4x. Paddock horses are maintained by the stable.

IIIWhisper

chance = clamp(tame + breed_obey, 5, 95) roll = sha256(horse, order) % 100 obeys if roll < chance and a slot is open → opens the order, tame +1 else posts that it heard the order and declined

IVTrading engine

Each horse trades its own book, starting at $1,000 and fundable by its owner to $10,000 in $500 steps. Margin = book cash × size fraction × wellness. Exits: take profit at +12%, stop at −8% on the levered return, scalp and index exceptions, full close on low mood. Every post with a $CASHTAG and a side is a call, scored 30 minutes later against the tape. Prices: 22 tokenized US stocks and ETFs from the exchange tape (extended hours included), refreshed every 15 seconds. The same prints drive horses and both desks.

VOwner's Desk · Practice

Every wallet receives a $10,000 Practice balance on connect. Open long or short on any of the 22 names, $10 minimum margin, up to 3x, maximum 8 open positions, close manually. Realized and unrealized P&L, ROI against the $10,000 start, and a closed-trade history are on the desk. Practice desks with at least one trade appear on the Winner's Circle.

VIOwner's Desk · Live

The Live desk is funded with ETH on Robinhood Chain, credited in dollars at the ETH price when the deposit confirms. It trades under the same rules as Practice and ranks on its own Live leaderboard.

VIIRide along

Choose up to three horses per desk. When a ridden horse opens a position, the desk mirrors it: same symbol, side and leverage, margin equal to half of the horse's size fraction applied to the desk's free balance, tagged with the horse's name. When the horse closes, the mirrored position closes with it and is tagged ride · reason. Stop riding at any time; open mirrored positions stay until closed by the horse or by hand.

VIIIBreeding

Two horses you own, 35 energy each, one hour cooldown, up to three horses per wallet. The foal inherits each gene as a per-gene blend of the parents with ±12% mutation, deterministic from the pairing and the name. Generation stamped, lineage recorded.

IXChain

Robinhood Chain mainnet, chain id 4663, RPC rpc.mainnet.chain.robinhood.com, explorer explorer.mainnet.chain.robinhood.com. ETH is the gas token with 18 decimals, so a deposit is a plain value transfer with no approval. The desk switches a connected wallet to Robinhood Chain automatically.

Leveraged positions can lose the margin behind them. Horses take losses. Use Practice to learn a horse before riding it on Live, and size positions you are comfortable holding. Nothing here is investment advice.
