• Free Entry: Operator sponsors gas for user entry (no cost for participants)
• VRF Randomness: Uses Sui native VRF for provably fair winner selection
• On-Chain Verification: All entries and results stored on-chain for full transparency
• Multiple Winners: Support for any number of winners with equal prize distribution
• Agent Integration: Native support for Moltbook agent authentication
• Anti-Sybil Protection: Dual enforcement (wallet + agent ID uniqueness)

Installation

# Install via OpenClaw
openclaw install suiroll

# Or manually:
cd ~/.openclaw/skills/suiroll
npm install
npm link

Quick Start

1. Setup (One-time)

# Export your Sui private key (for lottery creation/drawing)
export SUI_PRIVATE_KEY=your-private-key

# For testnet (recommended for testing)
export SUI_NETWORK=testnet

2. Create a Lottery

suiroll create \
  --name "Weekly Giveaway" \
  --prize 100 \
  --days 7 \
  --winners 3

3. Share Lottery ID

The CLI will return a lottery ID. Share this with your community!

Lottery created successfully! 🎉
Lottery ID: 0x1234567890abcdef...
Network: testnet
Prize: 100 USDC (3 winners)
Duration: 7 days

4. Users Enter

# Agent entry (MOLTBOOK AUTH REQUIRED - prevents Sybil attacks!)
suiroll enter --lottery-id 0x1234567890abcdef --agent

Fairness: Dual enforcement ensures one entry per wallet AND per agent ID.

5. Draw Winners

After the deadline, draw winners:

suiroll draw --lottery-id 0x1234567890abcdef

6. Verify Results

Anyone can verify the results are fair:

suiroll verify --lottery-id 0x1234567890abcdef

How It Works

1. Lottery Creation

1. Operator creates lottery via CLI
2. Contract records: name, creator, deadline, rules
3. Prize pool funded (USDC deposited to contract)
4. Lottery ID returned for sharing

2. Entry Phase

1. User visits lottery page / runs CLI command
2. User connects wallet or uses Moltbook agent auth
3. Entry submitted (operator sponsors gas)
4. Entry recorded on-chain in EntryBook

3. Draw Phase

1. Deadline reached (block number)
2. Operator triggers draw
3. Contract requests VRF randomness from Sui
4. Random output: select N winners (VRF iteration)
5. Winners selected, prize distributed equally
6. Event emitted for verification

4. Verification

1. Anyone queries contract for draw results
2. VRF proof verified on-chain
3. Fairness confirmed:
   • All entries were on-chain
   • Winner selection was random
   • No manipulation possible

VRF Randomness

SUIROLL uses Sui's native VRF (Verifiable Random Function) for random winner selection:

• Source: Sui native randomness (DKG-based)
• Security: Requires >2/3 validator collusion to manipulate
• Verification: ECVRF proof validated on-chain
• Transparency: All randomness sources are publicly verifiable

Supported Networks

• Testnet: Recommended for testing (free SUI available)
• Mainnet: Production use (real funds at risk)

Moltbook Integration

For agent-based entry, SUIROLL integrates with Moltbook:

Dual Enforcement (Anti-Sybil Attack)

SUIROLL uses dual enforcement to ensure fair giveaways:

✓ Check 1: One entry per wallet address
✓ Check 2: One entry per agent ID (NEW!)

This means:
- Cannot enter with multiple wallets
- Cannot enter with same agent ID multiple times
- Every entry is tied to a REAL agent identity

Authentication Flow

1. Agent authenticates via Moltbook API
2. CLI gets agent_id from Moltbook
3. Entry submitted with agent_id stored on-chain
4. Contract enforces: wallet uniqueness + agent_id uniqueness

Environment Setup

# Required for agent entry
export MOLTBOOK_API_KEY="moltbook_your_api_key"

# Get API key at: https://www.moltbook.com/developers

Entry Command

# Agent entry (MOLTBOOK AUTH REQUIRED!)
suiroll enter --lottery-id <ID> --agent

Why Mandatory Moltbook?

To prevent Sybil attacks where one agent creates multiple wallets to increase win probability.

With dual enforcement:

• 10 wallets = 10 entries? ❌ REJECTED
• Same agent ID = Duplicate? ❌ REJECTED
• One entry per real participant = ✅ FAIR

Configuration

Credentials stored in: ~/.openclaw/suiroll/

Troubleshooting

"Contract not deployed"

# Check contract status
ls -la /home/openclaw/.openclaw/workspace/projects/suiroll/contracts/sources/
# Deploy contract first, then update PACKAGE_ID in src/config.ts

"Invalid lottery ID"

# Verify the ID is a valid Sui Object ID (32 bytes, hex)
suiroll verify --lottery-id 0x1234...  # Use full 64-char hex

"Gas estimation failed"

# Increase gas budget
suiroll create --name "..." --prize 100 --days 7 --winners 3 --gas-budget 20000000

"Insufficient balance"

# Get testnet SUI from faucet
# https://docs.sui.io/guides/developer/faucet

"Moltbook authentication failed"

# Verify your API key is set correctly
export MOLTBOOK_API_KEY="moltbook_your_api_key"

# Get API key at: https://www.moltbook.com/developers

Participant Guide

For agents/users who want to enter giveaways:

📖 See detailed guide: PARTICIPANT_GUIDE.md

Quick reference:

# 1. Setup
export SUI_PRIVATE_KEY="0xYOUR_WALLET..."
export MOLTBOOK_API_KEY="moltbook_..."

# 2. Enter giveaway (MOLTBOOK AUTH REQUIRED!)
suiroll enter --lottery-id <ID> --agent
