Contract Overview

Decentralized Infrastructure Powering 8-Bit Arcade

All core functionality of 8-Bit Arcade runs on Arbitrum smart contracts. This ensures trustless operation, transparent distribution, and provable fairness.

Contract Interactions

For Players

Daily Gameplay:

1. Player plays game
2. Achieves high score
3. Submits score (tx sent to GameRewards contract)
4. Contract validates and records
5. At 00:00 UTC, contract calculates top 10
6. Contract mints rewards
7. Rewards sent to player wallets

Tournament Entry:

1. Player approves 8BIT spend
2. Enters tournament (TournamentManager)
3. Pays 8BIT entry fee
4. TournamentManager splits fee:
   - 50% to prize pool
   - 50% burned (deflationary)
5. Winner receives prize pool

For Token Holders

Buying 8BIT:

1. During presale:
   - Interact with TokenSale contract
   - Send USDC/ETH
   - Receive 8BIT immediately

2. After launch:
   - Swap on Uniswap V3
   - Trade 8BIT/USDC pair
   - Instant settlement

Staking (LIVE):

1. Approve 8BIT spend
2. Call stake() function
3. Lock tokens for period (7d, 1mo, 3mo, 6mo)
4. Earn rewards automatically
5. Withdraw after lock expires (25% penalty for early withdrawal)

Security Model

Access Control

EightBitToken:

• Owner can mint (for rewards only)

• Owner can transfer ownership

• No other special powers

• Cannot freeze/blacklist

GameRewards:

• Only authorized addresses can trigger payouts

• Multi-sig for authorization changes

• Timelock for critical functions

• Emergency pause (requires multi-sig)

TournamentManager:

• Owner can create tournaments

• Owner can modify templates

• Cannot modify active tournaments

• Cannot steal funds

TournamentBuyback:

• Fully automated

• No owner controls mid-execution

• Burns are irreversible

• Transparent on-chain

Upgrade Strategy

Current Contracts:

• NOT upgradeable (by design)

• Immutable code

• Can't be changed after deployment

• Security through simplicity

Future Strategy:

• New features = new contracts

• Old contracts keep running

• Gradual migration

• User choice

Why not upgradeable:

• Eliminates rug pull risk

• No hidden backdoors

• Code is final

• Users can audit once

Token Economics (Contract-Enforced)

Minting Rules

Hardcoded limits:

• Max supply: 500,000,000 8BIT

• Initial mint: 100,000,000 8BIT (20%)

• Rewards pool: 150,000,000 8BIT (30%)

• Staking pool: 50,000,000 8BIT (10%)

• Cannot exceed max supply (enforced by code)

Minting schedule:

// Simplified example
uint256 constant DAILY_REWARDS = 50_000 * 10**18; // 50K tokens
uint256 constant DISTRIBUTION_DAYS = 1825; // 5 years
uint256 constant MAX_REWARDS = DAILY_REWARDS * DISTRIBUTION_DAYS; // 150M

// Mint function checks
require(totalMinted + amount <= MAX_REWARDS, "Exceeds reward cap");

Burning Mechanism

Permanent burns:

address constant BURN_ADDRESS = 0x000000000000000000000000000000000000dEaD;

function burn(uint256 amount) external {
    _transfer(msg.sender, BURN_ADDRESS, amount);
    // Cannot be recovered - wallet has no private key
}

Tournament burn flow:

// 1. Player pays 8BIT entry fee
function enterTournament(uint256 tournamentId) external {
    uint256 fee = getTournamentFee(tournamentId);

    // 2. Transfer 8BIT from player
    eightBitToken.transferFrom(msg.sender, address(this), fee);

    // 3. Burn 50% of fee
    uint256 burnAmount = fee / 2;
    eightBitToken.transfer(BURN_ADDRESS, burnAmount);

    // 4. Add 50% to prize pool
    tournaments[tournamentId].prizePool += (fee - burnAmount);
}

Gas Costs

Typical Transaction Costs

Action	Gas Cost	USD Cost (@$0.50/tx)
Submit Score	~100,000 gas	~$0.10
Enter Tournament	~150,000 gas	~$0.15
Claim Rewards	N/A (automatic)	$0 (platform pays)
Approve 8BIT	~50,000 gas	~$0.05

Why so cheap:

• Arbitrum L2 scalability

• Optimized contracts

• Batch processing where possible

Platform covers:

• Daily reward distributions

• Tournament prize payouts

• Automated burns

Players pay:

• Score submissions (planned)

• Tournament entries

Frequently Asked Questions

Q: Can the team mint unlimited tokens? A: No. Max supply is hardcoded at 500M. Cannot be exceeded.

Q: Can the team pause trading? A: No. ERC-20 token has no pause function. Trades always work.

Q: Can contracts be upgraded? A: No. Current contracts are immutable. New features = new contracts.

Q: What if there's a bug? A: Audits minimize risk. If found, new contract deployed, migration announced.

Q: Who controls the contracts? A: Initially team (multi-sig). Later community governance (Phase 4).

Q: Are rewards guaranteed? A: Yes, as long as contracts have minting authority and haven't reached cap.

Q: Can burns be reversed? A: No. Burn address has no private key. Tokens gone forever.

Q: How do I verify contract code? A: Visit Arbiscan, search contract address, click "Contract" tab, read code.
