🌱 SPROUT.farm Whitepaper

Grow your farm. Earn while you sleep.

SPROUT.farm is an idle NFT farming game built on Solana. Players connect a Phantom wallet, collect plants across four rarities of collectible art, place them in garden beds, and watch them generate $SPROUT — the game's token — 24 hours a day, even while offline.

The rarer and more leveled a plant is, the more it produces. Plants can be leveled up, watered for temporary production boosts, fused together for a chance at even rarer plants, traded on an in-game marketplace, and sold or bought through a rotating shop. This document describes every system in the game as it exists today, plus the token and roadmap plans for when SPROUT.farm moves from Devnet to Mainnet.

🚀 2. Getting Started

1. Connect your Phantom Wallet — one click, no sign-up, no email.
2. Receive 4 free Starter Sprouts — automatically placed in Bed 1 of Garden 1. They produce a small, steady amount of $SPROUT and can never be sold or leveled, but can be removed to your inventory if you want the bed space.
3. Open your first Loot Box or buy directly from the Shop to get real, levelable plants.
4. Place plants in beds to start production, water them daily, and use Auto-Organize to always keep your strongest plants in your best slots.

🏡 3. Gardens & Beds

Every player's farm is made of up to 4 Gardens, each with the exact same layout:

Auto-Organize

One click sorts every real (non-starter) plant you own — across inventory and all unlocked gardens — by production rate, descending, and fills every available slot starting with Garden 1, then overflowing into Garden 2, 3 and 4 in order. Starter Sprouts only occupy slots left over once every real plant has a home. Anything that doesn't fit stays safely in your inventory.

🌿 4. Plants & Rarities

There are 45 unique collectible plants (40 general + 5 Garden Plants exclusives) plus the free Starter Sprout, spread across 6 purchasable rarities:

Dandelion

Sunflower

Orchid

Golden Cactus

Eden Tree

Cosmic Flower ✨

Cosmic plants cannot be sold or bought directly — they only come from a Founder Box or from fusing two Legendary plants (see Fusion). Free Starter Sprouts have a tiny fixed rate, can't level, and can't be sold or listed.

⬆️ 5. Leveling System

Every levelable plant can be leveled from 1 to 20 by spending $SPROUT.

• +1% production per level — flat and simple.
• A level-20 plant produces exactly +20% more than the same plant at level 1. No hidden multipliers.

Plants earn XP passively at their production rate (1 $SPROUT/s of rate ≈ 1 XP/s). The total XP required to reach level 20 is tuned per rarity so that, under normal play, it takes about:

Players can also instantly skip to the next level by paying $SPROUT — priced at 5× the XP still needed for that level.

💧 6. Watering

Watering cans are a consumable item. Using one on a plant grants a rolling 24-hour production bonus — but the size of that bonus is not fixed. It equals your current watering streak, in percent.

• The streak advances once per day, the first time you water at least one plant that day.
• Missing more than 48 hours between waterings resets the streak to zero.
• The same streak percentage also increases your Loot Box drop-rate bonus (see Loot Boxes), shifting some odds away from Common toward Rare/Epic/Legendary.

Watering Can Packs (Shop → Boosters)

XP Boosters (Shop → Boosters)

A separate consumable that multiplies all XP gain by 1.5× while active:

🧬 7. Fusion

Fusing two plants of the same rarity consumes both and produces one plant of the next rarity up. Every fusion also costs $SEED:

Fusing two Legendary plants is the only way to obtain a Cosmic plant outside of a Founder Box, at a 50% success chance. The $SEED fee is charged whether the Legendary → Cosmic roll succeeds or not.

🌱 8. $SEED Token

$SEED is a second, exclusively in-game currency — separate from $SPROUT. It exists for one purpose: buying plants on the Marketplace and in the Garden Plants store.

Once converted, $SEED cannot be withdrawn, sold, or turned back into $SPROUT — spend it deliberately.

📦 9. Loot Boxes

🎁 Free Starter Box

🎁 Starter Bundle

🌾 Seed Box

👑 Founder Box

Free Starter Box — Free, 1× per wallet

A welcome gift for every new player — same odds as the Seed Box below, at no cost. Claimable from the connect screen, a first-login welcome modal, or anytime from the Popular/Loot Boxes shop tabs until claimed.

Seed Box — 0.05 SOL

One random plant, any rarity except Cosmic:

Founder Box — 1.5 SOL (1× per wallet, limited to 500 total)

• 1× guaranteed Cosmic plant
• 3× guaranteed Legendary plants
• 48 Watering Cans
• 7 days of XP Boost
• +1 bed instantly unlocked in your farm
• Exclusive Founder badge, shown permanently next to your wallet — Founders get early access to future events and perks

Starter Bundle — 1× per wallet

Priced at 4 Seed Boxes with a 10% discount (0.18 SOL). Contains:

• 4× random plants (rolled with Seed Box odds)
• 12 Watering Cans
• 24 hours of XP Boost

🛒 10. Shop

Launch Phase 1 (first 2-3 weeks): direct-buy Premium Plants and Daily Deals are restricted to Epic and Legendary only. Common, Uncommon, and Rare plants can only be obtained from the Seed Box during this window — this keeps the early economy scarcity-driven and gives the Seed Box real value before direct-buy convenience opens up. After Phase 1, all rarities become directly purchasable again (see Phase 2 below).

👑 Founders Shop

A permanent perk for Founder Box owners: every day at UTC midnight, four items rotate in at a steep discount — the Seed Box, an XP Boost, a Watering Can pack, and one featured plant. Each item can be claimed once per day per wallet. It's a standing thank-you for early supporters, on top of everything the Founder Box already grants (Cosmic + Legendary plants, watering cans, XP boost, a free bed, and the permanent Founder badge).

Garden Plants (priced in $SEED)

These 5 plants are exclusive to the Garden Plants store — they never drop from Loot Boxes, Daily Deals, Featured rotations, Founder Boxes, or Fusion.

⚖️ 11. Marketplace

Players can list any sellable plant (everything except Cosmic and free Starter Sprouts) for $SEED, at or above a rarity floor price. Buyers pay in $SEED from their in-game balance — convert $SPROUT → $SEED in the Wallet first if you need to.

Every completed sale charges the seller a 5% platform fee, paid to the game's treasury wallet.

🌾 12. Hold Bonus

The more $SPROUT a player holds (rather than spends), the higher a flat production bonus applied across their whole farm — a tiered ladder, not a smooth curve:

⚡ 13. Power & Withdrawals

Every plant has a Power stat based on rarity and level, separate from its production rate — shown on your Stats tab as a general strength/collection metric.

Power also grows +12% per plant level, same 1-to-20 range as production.

🎯 14. Quests

The Quests page is split into four tabs, each shown as a grid of square quest cards. Every quest rewards XP (fed into the Season Pass) and $SPROUT:

• Daily: 5 shown at a time, drawn from a pool of 10 (watering, opening boxes, earning $SPROUT, leveling, placing plants, visiting the market, fusing, buying). Refresh at UTC midnight.
• Weekly: 3 shown at a time, drawn from a pool of 7 tougher, higher-reward objectives (watering streaks, bigger earn targets, multiple fusions, market sales). Refresh weekly.
• Monthly: 4 shown at a time, drawn from a pool of 6 — the biggest recurring goals (50,000 $SPROUT earned, 60 waterings, 10 fusions, 10 level-ups, 10 boxes opened, 5 Marketplace sales). Refresh on the 1st of each UTC month.
• Achievements: permanent, one-time goals that don't reset — things like unlocking every Garden, reaching level 20 on a plant, owning a Cosmic plant, opening a Founder Box, or hitting Farm Pass level 10/50. Each can only be claimed once, ever.

🎟️ 15. Season Pass ("Farm Pass")

A 100-level progression track (1,000 XP per level, fed by quest completions) with both a Free and a Premium reward line — Premium unlocks for 0.5 SOL per season.

🪙 16. $SPROUT Tokenomics

Total Supply: 50,000,000 $SPROUT.

$SPROUT will launch on-chain on Solana once the game reaches critical mass. All $SPROUT earned in-game during Devnet will be convertible at launch.

🗺️ 17. Roadmap

🔒 18. Security & Fairness

• SPROUT.farm never asks for your seed phrase. Wallet connection happens directly through Phantom.
• The game only reads your public wallet address and requests your approval for each SOL transaction (Loot Boxes, bed/garden unlocks, shop purchases).
• All rarity odds, fusion chances and reward formulas are defined in the game's public client code and applied identically to every player.

⚠️ 19. Disclaimer

SPROUT.farm is currently in active development on Solana Devnet. Numbers, prices, odds and mechanics described in this document reflect the current build and may change before Mainnet launch. Crypto assets involve risk. Nothing in this document is financial advice.
