Staking, and Tournament — GameFi Smart Contract Suite — Complete Implementation of Token, NFT, Staking, and Tournament
A complete GameFi system requires four contract categories: governance token, utility token, NFT items, and game mechanics (staking, tournament, crafting).
contract GameTournament is ReentrancyGuard, Ownable { IERC20 public lootToken; IERC721 public gameItems; // Required to enter (character NFT) struct Tournament { string name; uint256 entryFee; // LOOT tokens required to enter uint256 prizePool; // Accumulated from entry fees uint256 startTime; uint256 endTime; uint256...
contract GameCrafting is ReentrancyGuard, Ownable { IERC20 public lootToken; GameItems public gameItems; // The NFT contract with GAME_SERVER_ROLE struct Recipe { uint256[] ingredientTokenIds; // NFT token IDs required uint256 lootCost; // LOOT tokens burned uint256 outputItemTypeId; // The item type minted as result u...
Common integrations: The Graph, Alchemy/Infura, OpenZeppelin Defender, and popular wallet providers.
Clarify requirements, compliance needs, architecture risks, and launch goals.
Implement core contracts, integrations, product flows, tests, and deployment automation.
Run QA, prepare audit handoff, deploy infrastructure, and support production rollout.
For high-stakes crafting (burning valuable items for a chance at a legendary): Chainlink VRF. The verifiable randomness prevents accusations that the developer manipulated outcomes. For routine low-stakes crafting: on-chain pseudo-random (block.prevrandao) is acceptable — the value at risk is low enough that the manipulation incentive does not justify Chainlink's additional cost and latency.
