icp_gamebot

A Telegram bot for betting ICP tokens on emoji dice games. Players type a bet amount, pick a game, and win or lose based on the roll result.

How It Works

1. Player sends a bet amount (in $ICP) to the bot in the game thread
2. The bot checks the player's balance on the ICP ledger via ICRC-1
3. Player selects a game from the inline keyboard
4. The bot sends a Telegram dice animation in the selected game
5. Win/loss is determined by the roll value, and ICP is transferred accordingly

Tech Stack

• Language: Rust
• Telegram Bot: teloxide 0.12
• Async Runtime: tokio
• Ledger: ICP via ICRC-1 (calls dfx canister call --ic)
• Number Formatting: numfmt

Prerequisites

• Rust toolchain (latest stable)
• dfx (ICP Canister SDK) installed and configured
• A Telegram bot token (from @BotFather)
• An ICP ledger canister ID (ryjl3-tyaaa-aaaaa-aaaba-cai on mainnet)
• A TREASURY dfx identity with funds for paying out winnings

Configuration

Open src/main.rs and set your values:

let bot = Bot::new("YOUR_TELEGRAM_BOT_TOKEN");
const TREASURY_PRINCIPAL: &str = "YOUR_TREASURY_WALLET_PRINCIPAL";
const TREASURY_IDENTITY: &str = "TREASURY"; // dfx identity name
const GAME_THREAD_ID: i64 = YOUR_FORUM_THREAD_ID;
const GAME_CHAT_ID: i64 = YOUR_CHAT_ID;

Build and Run

cargo build --release
cargo run --release

The bot listens for messages in the configured chat and thread. Players interact entirely through the Telegram UI.

ICP Transfers

• Bets are transferred from the player to the treasury before the game
• Winnings are transferred from the treasury to the player on a win
• Losses stay in the treasury
• All transfers use dfx canister call --ic ryjl3-tyaaa-aaaaa-aaaba-cai icrc1_transfer
• Balances are checked via icrc1_balance_of
