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.
Positions & Archetypes
Each player has a primary position and an archetype that nudges their strengths and growth curve.
| Line | Positions | Common Archetypes |
|---|---|---|
| Attack | ST, LW, RW, CAM | Poacher, Target Man, Raider, Creator |
| Midfield | CM, CDM, LM/RM | Box-to-Box, Destroyer, Playmaker |
| Defense | CB, LB, RB | Stopper, Ball-Playing, Wingback |
| Goalkeeper | GK | Shot-Stopper, Sweeper-Keeper |
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.
