Terms of Service

Effective Date: September 24, 2026
Last Updated: September 28, 2026

1. Acceptance of Terms

Dungeons & Moles ("the Game", "we", "us") is developed and operated by Ailton Sávio Sacramento Júnior, an individual based in Brazil. By signing in to, or otherwise using, the Game through the Android app or the web client at app.dungeonsandmoles.com, you agree to these Terms of Service ("Terms") and to our Privacy Policy. If you do not agree, do not use the Game.

2. Eligibility

3. Description of Service

Dungeons & Moles is a fully on-chain PvE roguelike dungeon crawler built on the Solana blockchain. The Game includes:

• PvE Campaign: Seeded dungeon exploration with auto-resolving combat, POI interactions, and weekly boss fights
• PvP Modes: Gauntlet, Duels, and Pit Draft competitive modes
• NFT Marketplace: Trading of in-game items as on-chain assets
• Guest Mode: A local-only experience that does not require a wallet or blockchain interaction

All gameplay logic executes on-chain via Solana smart programs and MagicBlock Ephemeral Rollups. The Game uses Verifiable Random Functions (VRF) to ensure provably fair randomness.

4. Account and Wallet

4.1 Wallet-Based Authentication

The Game uses Solana wallet-based authentication exclusively. We support Phantom, Solflare, and Backpack wallets. There are no traditional accounts with usernames and passwords.

4.2 Wallet Security

You are solely responsible for:

• Maintaining the security of your wallet, seed phrase, and private keys
• All activity that occurs through your connected wallet
• Any losses resulting from unauthorized access to your wallet

We never have access to your wallet private keys or seed phrase. We cannot recover your wallet or reverse transactions if your wallet is compromised.

4.3 Session Keys

During gameplay, the Game creates temporary session keys derived from your wallet signature. These session keys sign in-game transactions on your behalf so you do not need to approve each individual action. Session keys are:

• Derived deterministically from your wallet signature
• Stored securely on your device (Expo SecureStore on native, sessionStorage on web)
• Limited in scope to in-game actions only
• Temporary and cleared when the session ends

You are responsible for the security of the device on which session keys are stored.

5. Payments and Transactions

5.1 Cryptocurrency Payments

All payments in the Game are made in SOL or SPL tokens on the Solana blockchain. Current pricing:

• PvE Campaign Runs: 0.05 SOL for 20 runs (with 20 free runs on profile creation)
• Gauntlet Entry: 0.01 SOL per run
• Duels Stake: 0.1 SOL per match
• Pit Draft Stake: 0.1 SOL per match
• NFT Marketplace: Variable SOL amounts set by sellers

Prices are subject to change. Changes will be reflected in the Game interface before you confirm any transaction.

5.2 In-Game Wallet

Starting a session funds a session signer (your in-game wallet) from your main wallet, currently about 0.09 to 0.10 SOL, to pay account rent and network fees. Excess funds above the cap are returned automatically, and you can withdraw the balance through the profile menu when no session is active. SOL spent on rent for a session that gets stuck may not be recoverable.

5.3 Prize Pools, Rewards and Events

Gauntlet entry fees, part of PvP stakes, run-pack purchases and marketplace trades fund on-chain prize pools, paid out by the on-chain programs as described in the Game's documentation. Events may award cosmetic items such as skins. Unless we say otherwise in writing:

• Rewards are set by the on-chain programs and the published event rules, and may be changed or cancelled for future events
• We may withhold or reverse the effect of rewards obtained through bugs, exploits, bots or multiple accounts, where technically possible
• Devnet rewards have no monetary value and may not carry over to mainnet
• Paid competitions with prizes are regulated differently in different countries. It is your responsibility to make sure taking part is legal where you live, and we may restrict them in some regions

5.4 No Refunds

This includes:

• Entry fees and run purchases
• PvP stakes (win or lose)
• NFT marketplace purchases
• Any other SOL or token transfers made through the Game

By initiating a transaction, you acknowledge and accept that it is irreversible.

5.5 Transaction Fees

Solana network transaction fees (rent, gas) are paid by you or by the Game's session funding mechanism. These fees go to the Solana network, not to us.

5.6 No Fiat Currency

The Game does not accept or process fiat currency (USD, BRL, EUR, etc.) in any form. We do not process credit card, bank transfer, or any traditional payment method.

6. Game Status

Specifically:

• Transition to mainnet will be announced in advance
• Progress on devnet may or may not carry over to mainnet
• We make no guarantees about the timeline or nature of future releases

7. On-Chain Data and Immutability

All game state, transactions, and interactions are recorded on the Solana blockchain. This data is:

• Public: Anyone can view your wallet address, transactions, game progress, items, and match results
• Permanent: Blockchain data cannot be deleted, modified, or made private
• Transparent: All game logic is executed by on-chain programs that can be inspected

By using the Game, you consent to having your gameplay data stored publicly and permanently on the blockchain.

8. Fairness and Randomness

The Game uses Verifiable Random Functions (VRF) provided by on-chain oracles to generate randomness for map generation, combat, POI outcomes, and other game mechanics. VRF provides cryptographic proof that randomness was generated fairly.

While we use VRF to ensure fair randomness, we do not guarantee any particular outcome, win rate, or return on your SOL expenditure. The Game is a skill-and-chance-based experience, and losses are a normal part of gameplay.

9. Acceptable Use

You agree not to:

• Use the Game if you are under 18 years old
• Attempt to exploit, hack, or manipulate on-chain programs or game mechanics
• Use bots, scripts, or automated tools to gain an unfair advantage
• Engage in market manipulation on the NFT marketplace
• Harass, threaten, or abuse other players
• Use the Game for money laundering or any illegal activity
• Attempt to interfere with or disrupt the Game's infrastructure
• Reverse engineer, decompile, or create derivative works from the Game client (except as permitted by applicable open-source licenses)
• Misrepresent your identity or impersonate another person

Violation of these terms may result in suspension or termination of your access to the Game.

10. Notifications and Analytics

If you allow them, the Android app sends reminders and event news. You can turn them off in Settings or in your phone's settings. The Game collects play analytics and error reports as described in the Privacy Policy; you can turn play analytics off with Share play data in Settings.

15. Force Majeure

We shall not be liable for any failure or delay in providing the Game due to causes beyond our reasonable control, including but not limited to: Solana network outages, blockchain congestion, Ephemeral Rollup infrastructure failures, internet disruptions, natural disasters, government actions, pandemics, or any other force majeure event.
