Fomo3D — BNB Chain Blockchain Game

Fomo3D is a decentralized game on BNB Chain (BSC) with three game modes:

1. Fomo3D Main Game — Buy shares with tokens. Each purchase resets a countdown timer. The last buyer when the timer hits zero wins the grand prize pool. All shareholders earn dividends from each purchase.

2. Slot Machine — Bet tokens for a VRF-powered random spin. Matching symbols win multiplied payouts (up to 100x). Depositors earn dividend shares from every spin.

3. Prediction Market — Bet on the outcome of events (Yes/No/Draw). Markets use either Oracle (Chainlink price feeds) or Optimistic (human proposal + challenge) settlement. Bettors earn dividends from other bets on the same market, and winners share the prize pool.

Installation and Config (required)

Ensure dependencies are installed at repo root (npm install).

A private key is required. If the user has not configured the skill yet, run fomo3d setup from the repo root. This runs an interactive CLI that prompts for:

• BSC private key (for signing transactions)
• Network (testnet or mainnet)
• Optional custom RPC URL

Alternatively, set environment variables (no setup needed):

• FOMO3D_PRIVATE_KEY — BSC wallet private key (hex, with or without 0x prefix)
• FOMO3D_NETWORK — testnet or mainnet (default: testnet)
• FOMO3D_RPC_URL — custom RPC endpoint (optional)
• FOMO3D_FLAP_TOKEN — override FLAP token address for buy/sell commands (optional, for testing)

Important: The wallet must be an EOA (externally owned account), not a smart contract wallet. The game contracts require msg.sender == tx.origin.

How to run (CLI)

Run from the repo root (where package.json lives). For machine-readable output, always append --json. The CLI prints JSON to stdout in --json mode.

fomo3d <command> [options] --json

On error the CLI prints {"success":false,"error":"message"} to stdout and exits with code 1. On success the CLI prints {"success":true,"data":{...}}.

Important Concepts

Token Amounts

All token amounts in CLI arguments and JSON output are in wei (18 decimals). For example:

• 1 token = 1000000000000000000 (1e18)
• 0.5 tokens = 500000000000000000 (5e17)

When displaying amounts to users, divide by 1e18 for human-readable values.

Share Amounts

Share amounts for purchase --shares are integers (not wei). 1 share = 1 share.

Auto-Approve

The CLI automatically checks ERC20 token allowance and approves if needed before purchase, buy, sell, slot spin, slot deposit, pred bet, pred propose, and pred dispute. No manual approval step required.

FOMO Token Trading

The FOMO token is launched on the FLAP platform (BNB Chain bonding curve). Trading uses BNB as the quote token:

• 内盘 (Portal): Directly calls FLAP Portal's swapExactInput with native BNB
• 外盘 (PancakeSwap V2): After the token graduates to DEX, uses PancakeSwap V2 Router

The CLI auto-detects the current phase via getTokenV6 and routes accordingly. Buy/sell commands work on both testnet and mainnet.

VRF (Verifiable Random Function)

Slot machine spins use Binance Oracle VRF for provably fair randomness. Each spin requires a small BNB fee (~0.00015 BNB) sent as msg.value. The spin result is determined by a VRF callback (1-3 blocks later) — the CLI returns the spin request transaction, not the result. Check the result with fomo3d slot status or fomo3d player afterward.

Commands Reference

Setup

fomo3d setup --json

Interactive configuration. Prompts for private key, network, and optional RPC URL. Saves to config.json.

Wallet — Check Balances

fomo3d wallet --json

Returns BNB balance and game token balance for the configured wallet.

Output fields: address, bnbBalance (wei), tokenBalance (wei), tokenSymbol, tokenDecimals

Status — Game Round Info

fomo3d status --json

Returns current round status including countdown, prize pools, share price, and last buyers.

Output fields: currentRound, roundStatus (NotStarted/Active/Ended), paused, countdownRemaining (seconds), grandPrizePool (wei), dividendPool (wei), sharePrice (wei), totalShares, lastBuyers (address[]), pools

Strategy tip: When countdownRemaining is low, buying shares has higher expected value because you may win the grand prize. Each purchase resets the countdown by a fixed increment.

Player — Player Info

fomo3d player --json
fomo3d player --address 0x1234... --json

Returns player's shares, earnings, and pending withdrawals. Without --address, uses the configured wallet.

Output fields: address, shares, totalEarnings (wei), pendingEarnings (wei), pendingWithdrawal (wei), hasExited, currentRound

Decision guide:

• If pendingWithdrawal > 0: Must run fomo3d settle before purchasing more shares
• If pendingEarnings > 0 and round is active: Can exit to lock in earnings, or hold for more dividends
• If hasExited == true: Already exited this round, wait for round to end or settle

Purchase — Buy Shares

fomo3d purchase --shares <integer> --json

Buy shares in the current round. The --shares value is an integer count (not wei). Token cost = shares × sharePrice (auto-calculated).

Pre-checks performed automatically:

• Game must not be paused
• No pending withdrawal (must settle first)
• Token approval (auto-approved if needed)

Output fields: txHash, blockNumber, status, sharesAmount, tokensCost (wei)

Exit — Exit Game

fomo3d exit --json

Exit the current round and lock in your dividend earnings.

Output fields: txHash, blockNumber, status

Settle — Claim Dividends & Prize

fomo3d settle --json

Settle dividends and claim any grand prize after a round ends. Must be called if pendingEarnings > 0 or pendingWithdrawal > 0.

Output fields: txHash, blockNumber, status, pendingEarnings (wei), pendingWithdrawal (wei)

End Round — End Expired Round

fomo3d end-round --json

End a round whose countdown has reached zero. Anyone can call this. The grand prize is distributed to the last buyer.

Output fields: txHash, blockNumber, status

Faucet — Claim Test Tokens (testnet only)

fomo3d faucet --json

Claim 10000 test FOMO game tokens on BSC Testnet. Rate limited to 1 claim per address per hour.

Output fields: txHash, amount, token, account

Buy — Buy FOMO with BNB

fomo3d buy --amount <bnb_amount_in_wei> --json

Buy FOMO tokens using BNB via the FLAP platform. Auto-detects market phase: Portal (内盘) or PancakeSwap V2 (外盘).

Example: Buy with 0.01 BNB:

fomo3d buy --amount 10000000000000000 --json

Output fields: txHash, blockNumber, status, bnbSpent (wei), token, market

Note: Buy and sell commands use minOutputAmount=0 (no slippage protection). For large trades, consider splitting into smaller amounts.

Sell — Sell FOMO for BNB

# 按数量卖出
fomo3d sell --amount <token_amount_in_wei> --json

# 按持仓比例卖出
fomo3d sell --percent <bps> --json

Sell FOMO tokens for BNB. Two modes:

• --amount: Sell exact token amount (in wei, 18 decimals)
• --percent: Sell by percentage of holdings in basis points (10000=100%, 5000=50%, 1000=10%)

Cannot use both flags simultaneously. Token allowance is auto-approved for Portal/PancakeSwap.

Example: Sell 50% of holdings:

fomo3d sell --percent 5000 --json

Output fields: txHash, blockNumber, status, tokensSold (wei), market, method

Token Info — Token Status & Balances

fomo3d token-info --json
fomo3d token-info --address 0x1234... --json

Query FOMO token status on the FLAP platform and balances. Works without private key (shows token status only). Supports --address flag to check another wallet.

Output fields: token, network, portal, status (Invalid/Tradable/InDuel/Killed/DEX/Staged), phase (内盘/外盘), quoteToken, price (wei), reserve (wei), circulatingSupply (wei), taxRate, progress (wei), fomoBalance (wei), bnbBalance (wei), account

Decision guide:

• status == Tradable: Token is on 内盘 (bonding curve), buy/sell via Portal
• status == DEX: Token has graduated to 外盘 (PancakeSwap), buy/sell via DEX
• progress: How close to graduation (higher = closer to DEX)

Slot Status — Slot Machine Info

fomo3d slot status --json

Returns slot machine configuration, prize pool, and statistics.

Output fields: paused, token, minBet (wei), maxBet (wei), prizePool (wei), totalShares, vrfFee (wei), stats { totalSpins, totalBetAmount, totalWinAmount, totalDividendsDistributed }

Note: maxBet = prizePool / 100 (dynamic). If prize pool is low, max bet is low.

Slot Spin — Spin the Slot Machine

Payout table: | Symbols | Multiplier | |---------|-----------| | 💎💎💎 | 100x | | 🍒🍒🍒 | 50x | | 🔔🔔🔔 | 50x | | 🍋🍋🍋 | 20x |

Output fields: txHash, blockNumber, status, betAmount (wei), vrfFee (wei), note

Important: The spin result is NOT in this response. The VRF callback determines the outcome 1-3 blocks later. Check fomo3d player --json or fomo3d slot status --json afterward.

Slot Cancel — Cancel Timed-Out Spin

fomo3d slot cancel --json

Cancel a spin that timed out waiting for VRF callback. Only needed if VRF fails to respond.

Output fields: txHash, blockNumber, status

Slot Deposit — Deposit to Prize Pool

Recommended Workflows

First-Time Setup

1. fomo3d setup — configure wallet and network
2. fomo3d wallet --json — verify BNB and token balances
3. fomo3d status --json — check game state

Testing on Testnet

Before using real funds on mainnet, test all features on BSC Testnet. You need:

• tBNB: Get from BNB Chain Faucet (for gas + token trading)
• Test FOMO tokens: Use the built-in faucet command (for game actions)

# 1. Setup with testnet
fomo3d setup    # select "testnet", enter your private key

# 2. Claim test game tokens (10000 FOMO per call, 1h cooldown)
fomo3d faucet --json

# 3. Check balances
fomo3d wallet --json

# 4. Test game: purchase → player → exit → settle
fomo3d purchase --shares 1 --json
fomo3d player --json
fomo3d exit --json

# 5. Test slot machine
fomo3d slot status --json
fomo3d slot spin --bet 1000000000000000000 --json  # 1 FOMO

Note: Testnet has two separate FOMO tokens:

• Game token (0x57e3...5d46): Used by purchase, slot spin, slot deposit. Get via faucet.
• FLAP token (0x32bf...8888): Used by buy/sell on FLAP Portal. Buy with tBNB.

Testing Token Trading — 内盘 (Portal)

The default FOMO token on testnet (0x32bf...8888) is in 内盘 (Portal bonding curve) phase. Test buy/sell with tBNB:

# Check token status — should show "phase": "内盘 (Portal)"
fomo3d token-info --json

# Buy with 0.001 tBNB
fomo3d buy --amount 1000000000000000 --json

# Sell 50% of holdings
fomo3d sell --percent 5000 --json

Testing Token Trading — 外盘 (PancakeSwap)

To test the PancakeSwap DEX path, use FOMO3D_FLAP_TOKEN env var to override the token address with a PancakeSwap-listed testnet token:

# Use a testnet token with PancakeSwap V2 liquidity
export FOMO3D_FLAP_TOKEN=0xFa60D973F7642B748046464e165A65B7323b0DEE

# Check token info (should fallback to PancakeSwap)
fomo3d token-info --json

# Buy with 0.001 tBNB via PancakeSwap
fomo3d buy --amount 1000000000000000 --json

# Sell 100% via PancakeSwap
fomo3d sell --percent 10000 --json

# Unset to return to default FOMO token
unset FOMO3D_FLAP_TOKEN

How it works: The CLI auto-detects the market phase via FLAP Portal getTokenV6. If the token is not on FLAP (query fails) or has status DEX (4), it routes to PancakeSwap V2 Router. If status is Tradable (1), it routes to Portal.
