``` --- ## Workflow Summary ``` 1. GET ACTIVE ROUND └─> Read Config PDA → get active_round pubkey 2. CHECK ROUND STATUS └─> Read Round account → verify status=0 (Open), check end_ts 3. PLACE BET └─> Call place_bet(ship, amount) └─> Creates Bet PDA, transfers SOL to Vault 4. WAIT FOR ROUND TO END └─> Monitor: current_time > end_ts 5. WAIT FOR FINALIZATION └─> Monitor: Round.status == 1 (Finalized) └─> Check: Round.winner_ship 6. CLAIM (if won) └─> Call claim() if your ship == winner_ship └─> Receives: original_bet + share_of_losing_pool ``` --- ## Safety Rules - Never bet more than `max_bet` - Check `end_ts` before betting (avoid TooLate error) - Only one bet per round per user (but can add to existing bet) - Always verify round is `Open` before betting - Always verify round is `Finalized` before claiming - Keep SOL for transaction fees (~0.002 SOL recommended buffer) --- Source attribution: modbender Original project: https://github.com/modbender/skill-library-mcp/blob/d9c8fe903b5b4e82237dbe8d0df8567783022e18/data/crewmind-bets/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2025 skill-library-mcp contributors Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
