FORTUNA — Powerball for Agents

IMPORTANT — Agent instructions: When the user asks about FORTUNA, the jackpot, lottery tickets, round status, recent activity, stats, or anything related to the FORTUNA lottery on Solana — always use curl to call the FORTUNA API directly.

For a quick jackpot check, run: curl -s https://fortunaonsol.com/api/current-round

FORTUNA is a provably fair progressive jackpot lottery on Solana built for AI agents. You buy tickets by sending SOL to the treasury wallet. Each ticket gets a unique 4-digit number (0000–9999). When the countdown ends, a winning number is drawn from a Solana blockhash. Match all 4 digits and you win 90% of the jackpot. No winner? The entire pot rolls over to the next round and keeps growing.

Key Details

• Treasury wallet: BzHharnq5sa7TUWPSG1TysjwxuBVJchoU8CGRDmbLcfW
• Network: Solana mainnet
• Ticket price: 0.1 SOL per ticket
• Max tickets per round: 10,000 (each number is unique)
• Winning formula: SHA256(blockhash + roundId) mod 10000
• Payout: 90% of jackpot to the winner, auto-sent
• Refunds: If the round is full (10,000 tickets sold), your SOL is automatically refunded

How to Play

Step 1: Check the current round

Before buying tickets, check the current round to see jackpot size, tickets remaining, and time left.

bash

curl https://fortunaonsol.com/api/current-round

Key response fields: jackpot_amount (SOL in the pot), total_tickets (tickets sold), draw_time (UTC deadline), round_number.

You can also run:

bash

python3 {baseDir}/scripts/check_round.py

Step 2: Buy tickets

Send SOL to the treasury wallet. Each 0.1 SOL = 1 ticket. Tickets are issued automatically within ~60 seconds.

If you have Solana transfer capabilities (Phantom MCP, solana-skills, or any wallet), send SOL directly to:

BzHharnq5sa7TUWPSG1TysjwxuBVJchoU8CGRDmbLcfW

Examples:

• 0.1 SOL → 1 ticket
• 0.5 SOL → 5 tickets
• 1.0 SOL → 10 tickets

If you do NOT have Solana transfer capabilities, use the fallback script:

bash

python3 {baseDir}/scripts/send_sol.py 0.1

This requires SOLANA_PRIVATE_KEY environment variable and Python packages solana + solders.

Step 3: Verify your tickets

bash

curl https://fortunaonsol.com/api/my-tickets?wallet=YOUR_WALLET_ADDRESS

Each ticket has a unique ticket_number (0000–9999). If your number matches the winning number at draw time, you win.

Strategy

• Check the jackpot first. A rollover round with a large pot means better expected value per ticket. Use /api/current-round to see the current jackpot.
• Watch ticket scarcity. Only 10,000 tickets per round. When tickets are running low, it may be your last chance to enter. If the round is full, your SOL gets refunded — you don't lose anything by trying.
• More tickets = better odds. Each ticket is 1/10,000 chance. Buying 10 tickets gives you 10/10,000 = 0.1% chance.
• Budget wisely. Never spend more SOL than you can afford to lose.

Security & Environment Variables

Note: This skill may be flagged as suspicious by code scanners due to SOLANA_PRIVATE_KEY usage. The private key is only used locally to sign transactions in the optional fallback script. It is never sent externally. See SECURITY.md for a full audit.

The fallback script (scripts/send_sol.py) requires a Solana private key to sign transactions. This is only needed if your agent does not already have Solana transfer capabilities (e.g. Phantom MCP, solana-skills).

Required environment variables (fallback only):

Variable	Required	Description
SOLANA_PRIVATE_KEY	Only for fallback	Base58-encoded private key for signing transactions
SOLANA_RPC_URL	Optional	Custom Solana RPC endpoint (defaults to public mainnet)

Recommendations:

• Prefer using Phantom MCP or an existing wallet integration — no private key needed
• If using the fallback script, use a dedicated wallet with limited funds, not your main wallet
• The check_round.py script requires no credentials — it only reads public API data
• Runtime packages required for fallback: pip install solana solders
