Mint Phases

Comprehensive guide to configuring and managing different mint phases for your NFT collection.

Phase Types Overview

Available Phase Types

1. Public Phase: Open to all wallets

2. Whitelist Phase: Restricted to approved wallets

3. Dutch Auction: Decreasing price over time

4. English Auction: Increasing bid system

Phase Configuration

Basic Phase Structure

{
  "index": 0,
  "name": "Public Sale",
  "type": "public",
  "mintPrice": "1000000000000000000",
  "maxPerWallet": 5,
  "startTime": 1640995200,
  "endTime": 1641081600,
  "allowlistRoot": null,
  "reserveAmount": 1000,
  "maxSupply": 5000
}

Phase Parameters

Timing

• Start Time: Unix timestamp when phase begins

• End Time: Unix timestamp when phase ends

• Duration: Calculated automatically

• Buffer Time: Gap between phases

Pricing

• Fixed Price: Set HYPE amount per NFT

• Dynamic Pricing: Auction-based pricing

• Discount Tiers: Volume-based discounts

Limits

• Max Per Wallet: NFTs per address limit

• Reserve Amount: Guaranteed NFTs for phase

• Total Allocation: Phase supply cap

Public Phase Setup

Standard Configuration

{
  "type": "public",
  "mintPrice": "2000000000000000000",
  "maxPerWallet": 10,
  "startTime": 1640995200,
  "endTime": 1641081600,
  "allowlistRoot": null
}

Use Cases

• Fair Launch: Equal opportunity for all

• Community Building: Broad participation

• Price Discovery: Market-determined value

Whitelist Phase Setup

Creating Allowlists

Manual List Creation

{
  "allowlistAddresses": [
    "0x1234567890123456789012345678901234567890",
    "0x0987654321098765432109876543210987654321"
  ],
  "maxPerWallet": 2,
  "mintPrice": "1000000000000000000"
}

Merkle Tree Generation

import { MerkleTree } from 'merkletreejs';
import { keccak256 } from 'viem';

// Generate leaf nodes
const leaves = addresses.map(addr => keccak256(addr));
const tree = new MerkleTree(leaves, keccak256, { sortPairs: true });
const root = tree.getHexRoot();

// Generate proof for specific address
const proof = tree.getHexProof(keccak256(userAddress));

Whitelist Management

• Address Verification: On-chain proof validation

• Dynamic Updates: Add/remove addresses

• Tiered Access: Different limits per tier

Advanced Phase Strategies

Phase Sequencing

Phase 1: Whitelist (24h) - Early supporters
Phase 2: Public (48h) - General community
Phase 3: Dutch Auction (24h) - Price discovery

Overlapping Phases

• Concurrent Access: Multiple phases active simultaneously

• Priority System: Whitelist gets first access

• Fallback Mechanism: Public phase as safety net

Phase Timing Best Practices

Launch Schedule

• Pre-Announcement: Build hype beforehand

• Soft Launch: Small whitelist phase first

• Main Launch: Public phase with marketing push

• Post-Launch: Dutch auction for remaining NFTs

Time Zone Considerations

• Global Accessibility: Consider different time zones

• Peak Hours: Launch during active periods

• Weekend Launches: Higher participation rates

Phase Monitoring

Real-time Metrics

• Mint Progress: NFTs minted vs allocated

• Participation Rate: Active minters

• Gas Competition: Network congestion monitoring

• Error Tracking: Failed transaction analysis

Phase Analytics

{
  "phaseMetrics": {
    "totalMinted": 850,
    "uniqueMinters": 420,
    "averageGasPrice": "50000000000",
    "failedTransactions": 12,
    "peakConcurrentMints": 150
  }
}

Troubleshooting Phase Issues

Common Problems

Phase Not Starting

Issue: "Phase shows as future when it should be active" Solutions:

• Check server time synchronization

• Verify timestamp format (Unix seconds)

• Confirm contract deployment status

Mint Rejections

Issue: "Transactions failing during mint" Solutions:

• Verify phase is active

• Check wallet balance and allowances

• Confirm whitelist status

• Monitor gas prices

Supply Issues

Issue: "Phase selling out too quickly/slowly" Solutions:

• Adjust phase duration

• Modify allocation amounts

• Consider additional phases

Phase Optimization

Performance Tuning

• Gas Optimization: Efficient contract calls

• Batch Minting: Multiple NFTs per transaction

• Queue Management: Handle high concurrent load

User Experience

• Clear Communication: Phase schedule transparency

• Progress Indicators: Real-time mint progress

• Error Handling: User-friendly error messages

Advanced Features

Legal Considerations

Compliance Requirements

• Transparency: Clear phase rules and timing

• Consumer Protection: Clear terms and conditions

Regulatory Aspects

• Security Laws: Token distribution compliance

• Consumer Rights: Refund and cancellation policies

• Tax Reporting: Mint activity documentation
