Presale overview
Contribution options, transparency, and verification expectations.
Presale tiers (bonus structure)
- Tier 1: 0.1–1 ETH → +20% bonus tokens
- Tier 2: 1–5 ETH → +25% bonus tokens
- Tier 3: 5+ ETH → +30% bonus tokens
The calculator in the app estimates tokens received and bonus amounts automatically.
Token conversion (calculator)
The app uses an internal conversion rate of:
1 ETH = 100,000 OPN
The calculator then applies the tier bonus based on your entered amount.
Payment methods
- Manual: send ETH from your wallet to the presale address shown in-app.
- Web3 gateway: pay with ETH, BNB, or USDT (ERC20 / BEP20).
- Solana: optional Solana presale path (shown in-app if configured).
Minimums
- Web3 gateway: $50 minimum (USD input).
- NOWPayments donation option: minimum noted in-app (currently $50).
Verification & records
The platform stores presale transactions and uses network-aware verification logic (e.g., Ethereum vs BSC) when available.
- Transactions can be recorded with wallet address, amount (USD + crypto), network, and TX hash.
- The automated presale ledger summarizes totals and recent transactions.
Always verify you are using the official address shown inside the app before sending funds.
