Players
On Gaff, players are on-chain assets, living, evolving NFTs you actually own. You scout them, develop them, pick their roles and tactics, then decide whether to keep, loan, or sell.
What a Player Is
Player NFT (ERC-721): Immutable identity + evolving performance data. You hold the keys, you control the asset.
Provenance: Academy → Graduation → Contracts → Matches → Transfers recorded on-chain or in verifiable logs.
Composability: Tradable on the Gaff Marketplace, portable to partner apps and analytics tools.

Each player has a primary position and an archetype that nudges their strengths and growth curve.

Core Attributes
Strength (overall ability): Blend of technical, physical, and mental sub-attributes.
Pace, Finishing, First Touch, Vision, Aerials, Press Resistance, Defensive Shape: Impact simulations based on formation/tactics.
Stamina & Fatigue: Falls with minutes and drills, recovers over time or via shop items.
Injury Proneness: Raises risk at low stamina or heavy training loads.
Form (rolling): Last 5 match ratings stabilize or swing performance.
Simulation DNA: Formations, tactics, and minutes-weighted stamina affect expected goals, chance creation, and defensive solidity.
Lifecycle
Scouted Prospect (off-chain profile) Hidden ranges (e.g., STR 60–72) revealed by friendlies & drills.
Academy → Graduation Meet thresholds → mint to NFT, club chooses to keep, loan, or list.
Contracted Senior Appears in squads, earns minutes, builds form & stats.
Transfer/Loan Market-driven mobility with club- or player-friendly terms.
Development & Training
Drills (2/day per player): Finishing, First Touch, Pace, Vision, Defensive Shape, Aerials, Press Resistance. Diminishing returns prevent spam:
Δeffective = Δbase / (1 + 0.35 * recent_sessions)Fatigue:
stamina = max(0, stamina - ceil(minutes_equiv / 3))Low stamina increases injury risk in matches.Plans: Team-wide templates aligned to your formation, respects match days.
Items (Shop): Energy, Focus, Rehab, Morale, capped per week to avoid pay-to-win spirals.
Contracts & Economics
Ownership: Your wallet = your rights.
Contracts: Term + wage bands (soft), options (club/player), performance bonuses (e.g., goal milestones).
Loans: Duration, minutes guarantees, recall rules, fee structure.
Transfers: Fixed price, auction, or offers. Royalties route a small cut to the developing club (time-boxed).
Match Impact
Selection: Starters + timed subs. Null/empty slots are ignored safely (no sim crashes).
Events: Goals, assists, substitutions, injuries, all timestamped.
Ratings (1–10): Minutes, contributions, and role drive per-match ratings.
Form Curve: Rolling window (last 5) influences performance expectancy.
Rarity & Identity
Visual layers: Kits integrate club identity, collectible cosmetics (non-stat).
Rarity tags: “Academy Gem”, “Evergreen”, “Late Bloomer”, purely collectible, no stat bias.
Name & bio: Editable by owner (rate-limited, recorded in metadata history. Roadmap).
Trading & Liquidity
List Gasless, Settle On-Chain: Sign a listing, buyer settles on-chain.
Bids/Offers: Time-boxed offers, partial escrow.
Price Discovery: Match stats and form surface in marketplace cards.
Health & Fair Play
Anti-farm: Daily/weekly mint caps, position-balanced cohorts, region cooldowns.
Anti-sybil: Multi-signal checks (device, usage patterns) on academy progression.
Cooldowns: Rename, transfer, and drill caps to keep the market sane.
What Success Looks Like
Builders turn prospects into stars and monetize the delta.
Tacticians squeeze extra xG from role + instruction fit.
Traders arbitrage form swings and future schedules.
Club lifers build legends with multi-season continuity, something Web2 resets never allowed.
Quick FAQ
Can I sell anytime? Yes, outside of temporary competition locks (e.g., after brackets are seeded. Roadmap).
Do ratings reset? No, stats persist, form rolls naturally.
Are cosmetics pay-to-win? No, strictly visual.
Can I port data out? Yes, open APIs and on-chain events enable third-party dashboards(Roadmap).
TL,DR
Players on Gaff are real digital athletes: ownable, improvable, tradable. Your scouting, training discipline, and tactical nous aren’t just “save files”, they’re value you can hold, prove, and trade.
