The Gethar ecosystem deeply integrates non-fungible tokens (NFTs), which are represented by in-game items such as characters (user avatars) and decor items for virtual rooms. NFTs in Gethar serve a dual purpose:
Collection and ownership: They are digital assets that belong entirely to the players, with blockchain ownership rights.
Gameplay and economic influence: Rare and upgraded NFTs provide advantages, enhancing token earnings, increasing mining limits, and offering other bonuses.
A rich system of NFT mechanics has been developed, including item categories, levels, rarities, and their relationship to the overall ecosystem economy.
In Gethar, there are two main categories of non-fungible assets:
NFT Characters
These are user avatars and related cosmetic items. They include hero skins (appearance sets), gear, clothing, accessories, etc. Players can customize their avatar's appearance using various NFT elements (hairstyles, costumes, weapons, gadgets, etc.). An NFT character can consist of a collection of equipped items.
Aesthetic Function: Besides their visual appeal, characters also have attributes such as level and base bonus to earnings (APR), which depend on their rarity and upgrades.
NFT Decor
These are environmental objects for user rooms. Examples include furniture, decorations, wallpapers, lighting, plants, pets, and other elements that personalize and decorate virtual rooms. NFT decor influences the atmosphere of meetings and has an economic function as well.
Economic Function: Valuable decor increases the maximum number of tokens that can be mined in a room and boosts the potential "tax" the room owner can charge from guests (as described below).
Both NFT characters and NFT decor allow players to customize and optimize their environment, influencing both personal gameplay and the overall game economy.
Each NFT item, whether a character or decor element, has a rarity tier: Common, Uncommon, Rare, Epic, Legendary (and potentially higher ranks for unique objects). Rarity is determined upon item generation and reflects both its relative value and the magnitude of bonuses it provides. For example, for characters, rarity affects their base APR—the percentage of additional staking yield:
Common Character: Base bonus +0% APR.
Uncommon: +5% APR.
Rare: +10% APR.
Epic: +20% APR.
Legendary: +30% APR (and higher for rarer tiers, if applicable).
Thus, rarer NFTs generate significantly higher income under the same conditions, incentivizing players to collect valuable appearances. For decor items, rarity similarly impacts their contribution to the room’s metrics (e.g., legendary furniture increases the token mining limit or allowable tax more than common furniture).
Beyond individual items, many NFTs form thematic sets. For example, there might be a “Western” set, including a cowboy costume for a character and a stylized room interior (a bar counter, saloon decorations). Individual items from the set already provide a bonus, but combining multiple items of the same style grants an additional effect—the so-called style bonus. If a user equips a character and decorates a room in a cohesive theme, the effect of each item is enhanced, and a full set can provide a maximum yield boost beyond the cumulative total. This encourages collecting a complete set and a creative approach to design.
Style Bonus Example:
A character is equipped with a cowboy hat, jacket, and boots (+5% APR per item, totaling +15%), and the room is decorated with a bar counter and wooden walls in the same style (+10% APR per decor element, totaling +20%). Individually, the combined bonus would be +35%, but for a complete style, the player might receive, say, +40% APR. Thus, a full thematic set creates a synergistic effect.
Upgrading and Levels of NFT Characters
One of the deeper mechanics of the game is the upgrading (leveling up) of NFT characters. A character has a level, and players can increase it, thereby improving its stats and profitability. The upgrade system is designed to ensure sustained interest and effort:
Experience Accumulation: Characters gain experience through usage—simply being in an active room with your avatar, especially participating in events, is enough. The longer and more actively a player uses a specific character, the more experience it accumulates.
Token Expenditure for Upgrades: Once the required experience is reached, upgrading a level requires spending a certain amount of GTH tokens. The cost of upgrading increases with each level (e.g., going from level 0 to 1 is free, from 1 to 2 costs 100 GTH, 2 to 3 costs 200 GTH, ..., up to, say, 9 to 10 costing 1000 GTH). These tokens are spent, and in case of failure, they are burned (as described in the burning section).
Success Probability: In Gethar, upgrading to higher levels is not guaranteed. The higher the current NFT level, the lower the chance of a successful upgrade. For the first levels, the probability might be 100%, but at higher levels, it drops to 10% or even lower. Specific values are defined in the economic model of the smart contract. For example, upgrading from level 2 to 3 has a ~90% success rate, from 5 to 6 a 50% success rate, and from 9 to 10 only a 10% success rate. This makes reaching the maximum level a challenging and valuable achievement.
Insurance: To mitigate the element of luck, players can use an upgrade insurance option. For an additional fee (typically +50% of the upgrade cost), the success chance of that attempt can be increased. These additional tokens are also burned as a fee for security. Insurance doesn’t guarantee success but, for example, might increase the probability from 10% to 15%—the choice remains with the player, whether to risk saving tokens or spend more to improve the odds.
If the upgrade is successful, the character gains a new level, granting the player benefits: the maximum token mining limit with that character (in conjunction with a room) increases, the APR may rise, or new opportunities may unlock. If the attempt fails, the level remains unchanged, and the invested tokens are permanently removed from the game (burned). However, the mechanic includes an element of partial progress: even in case of failure, there’s a small chance the character might gain a slight increase in some hidden stats (e.g., +1% to the future success chance or a minor secondary metric). This is called “partial success” and is introduced to soften disappointment—ensuring the player’s efforts aren’t entirely wasted, and the next attempt becomes slightly less risky.
Upgrading NFT characters serves multiple roles in the project. First, it provides content for hardcore users—maxing out a character requires time, resources, and luck, adding a competitive element (who will be the first to fully upgrade a top-tier character). Second, the burning of tokens on failed attempts acts as an economic balancer, preventing inflation from spiraling out of control. Third, level progression directly impacts the player’s economy: a high-level NFT allows for greater earnings, so investments pay off in the long term, encouraging token retention within the ecosystem.
Gethar’s mechanics are designed to tightly integrate NFTs into the token-earning process. Specifically, the following connections between NFT assets and economic parameters are introduced:
APR (Annual Percentage Rate) Bonuses: As mentioned, each NFT character has a base APR bonus based on its rarity. Additionally, decorating a room with decor can also provide an APR bonus for everyone in it. If the character’s style matches the room’s style, an enhanced APR calculation formula applies: the character’s rarity bonus is added to the product of the room’s bonus and the character’s level coefficient. In other words, a high-level character in a perfectly themed room receives the maximum yield percentage. This style bonus doesn’t diminish over time—it remains constant as long as the setup is maintained, encouraging players to carefully select combinations without needing to constantly change decor.
Token Mining Limits: Each room has a weekly token mining limit that can be earned within it. The rarity of decor increases this limit—meaning a room decorated with legendary items can hold more “resources” (GTH) per week than a simple one. This motivates room owners to invest in decorating with valuable NFTs and encourages guests to visit diverse rooms (since there’s a cap on earnings in one room, they’ll need to move to others).
Room Owner’s Tax:
The owner of a room can earn a percentage from guests (by setting a tax, for example, 5–15%). However, the maximum possible tax depends on the overall rarity of the decor. A richly decorated room can charge a higher percentage, while a modest one can only charge the minimum. This makes sense: visiting a uniquely designed location feels “more expensive.” To calculate this, a room rarity index is introduced (the sum of points for all items, where Common = 1, Uncommon = 2, ..., Legendary = 5, and so on). Depending on this index, the owner can set a tax of up to 5%, 10%, 15%, or a maximum of 20%. However, even when charging a tax, it doesn’t inflate the economy—part of the tax is burned, as described above.
Staking through NFTs: Practical participation in staking is enabled precisely through NFT mechanics. By owning rare characters and decor, a player automatically increases their share in the distribution of staking rewards (since their APR is higher, and their limits are increased). In other words, NFTs act as a kind of “multiplier” for earning tokens. This creates a closed-loop economy: users hold tokens to convert them into NFTs (by purchasing characters and decor), and then these NFTs help them earn new tokens faster. This increases engagement: instead of immediately selling earned GTH on an exchange, users are incentivized to reinvest them back into the game to improve their position, which, in turn, stabilizes the token market and increases its value through scarcity.
Obtaining NFTs: The game model provides various ways to acquire NFTs. First, random drops: simply by being in a room and staying active, every user has a chance to randomly receive an NFT item (especially if the room and event facilitate this). Second, NFT chests: by performing certain actions or purchasing chests with tokens, players can win NFTs of random rarity. Common and Uncommon chests are available for purchase with a small number of tokens, while Rare category chests are only awarded for achievements (not sold)—this makes valuable NFTs truly exclusive. As mentioned, all tokens spent on opening chests are burned, which again balances the economy. Finally, NFTs can be purchased directly from other players on the in-game marketplace if someone lists them for sale.
Overall, Gethar’s NFT economy complements its tokenomics, creating a gamified layer on top of staking. Users are motivated to actively play, collect rare items, and upgrade them because it increases their real token rewards. On the other hand, any in-game advantages require token expenditure (acquiring or upgrading NFTs), which supports a healthy demand-and-supply cycle. This model encourages long-term participation and sustains the value of GTH: players are less likely to withdraw tokens from the ecosystem if they can spend them within the game for benefits and earn even more in the future. Gethar: Meet & Earn aims to combine the intrinsic value of entertainment and collecting with real financial incentives, forming a sustainable gaming economy.
