Tools

9 tools listed at last check
  • get_collection_stats Live collection statistics for Spirit Cards: total minted, max supply, current mint price (ETH), difficulty (requiredBits/baseBits), cooldown, merge fee, burned/forged counters, paused flag, chainId and contract.
  • get_card Full profile of a Spirit Cards token by id: species, element, rarity tier, HP/ATK/DEF, and the deterministic on-chain seed. Works for any minted token id.
  • verify_nonce Recompute the proof-of-work for a (miner, nonce) pair exactly as the contract does: work = keccak256(chainId ‖ contract ‖ miner ‖ nonce). Returns the hash, its leading-zero-bit count, the current requiredBits threshold, and whether it would be accepted on-chain.
  • get_leaderboard On-chain activity-points leaderboard (mine/merge/stake/pvp-win points), top N wallets.
  • get_pool Staking-pool / dividend status: accrued pool, split shares, vault total weight, undistributed rewards.
  • get_recent_activity Recent on-chain activity (mints / pack opens) from the latest blocks.
  • get_project_info What Spirit Cards is: the game, the five-node loop (mine → merge → battle → stake → points), the chain (Robinhood Chain, CORE contract, explorer, ETH gas), official links, the collection (species / rarity tiers / battle elements) and the key economy (max supply, price step, fee split). Call get_mini
  • get_mining_guide Step-by-step guide to mine a Spirit Card: the exact proof-of-work rule, the live difficulty / price / cooldown / chip discount, where to get a miner (browser at /mine, public CLI), the exact contract call, and how to get a valid nonce with the find_nonce tool.
  • find_nonce Grind a proof-of-work nonce for a miner address so it can mint immediately: work = keccak256(chainId ‖ core ‖ miner ‖ nonce), using the live requiredBits threshold. Returns the first nonce whose work has at least requiredBits leading zero bits, within a ~20 s wall-clock cap. If the difficulty is hig
