Fair Launch Mechanics for Zora Content Coins

30-Minute Maturity Period

• Pool all initial buys during this window.
• Compute a weighted average price based on total capital committed.
• Execute a single batch swap on the bonding curve at maturity end.
• Distribute tokens proportionally—rewarding commitment over speed.

“Rewards capital commitment over sniper speed.”

Implementation via Hook Extensions

1. Maturity Phase - Use afterSwap to intercept buys. - Enforce flat issuance via custom delta (fixed token/ETH ratio). - Track contributions in hook state.

2. Post-Maturity Migration - Batch-execute pooled liquidity. - Migrate to standard V4 tick positions for normal trading.

Extend ContentCoinHook, deploy custom version, register via postDeployHook.

Anti-Dump: Inverted Bonding Curve Vesting

• Hook tracks presale contributions per address.
• Tokens vest via inverted bonding curve (linear unlock over 2–4 hours).
• balanceOf() computed on-the-fly—no transferable tokens until vested.

function computeVestedBalance(...) external view returns (uint256) {
    uint256 elapsed = block.timestamp - maturityEnd;
    return total * elapsed / vestingDuration; // Linear unlock
}

Deployment & Integration

• Use factory.postDeployHook to initialize timers and state.
• Register custom hook in HookRegistry for discovery and future migrations.
• Fully compatible with existing Content Coin flows.

Alternative Paths (Deeper Changes)

• Upgrading the canonical ContentCoinHook.
• Factory-level defaults for maturity/vesting.
• Governance or admin-set parameters.

“You could do it a lot easier without hooks but would require deeper changes to Zora.”
