Calculator

Two utilities in one page. No state, no persistence — just calculators.

Unix time converter

For time-gated mints. Paste either side, get the other:

• Unix seconds ↔ readable local + UTC.
• Readable local ↔ Unix seconds + UTC.

Useful when a contract has startTime baked in as a Unix timestamp and you need to know “is that now?” in your timezone.

EIP-1559 gas calculator

Plug in:

• Gas limit — typical mint: 100k-300k. Get a real number from a previous successful tx if possible.
• Max fee per gas (gwei) — your ceiling.
• Max priority fee per gas (gwei) — your tip.
• Token price (USD) — current ETH/ETH-like price.

Get out:

• Worst-case cost in native gwei, native units, and USD.
• Expected cost (using priority fee + current base fee) in the same units.

The page shows the current base fee for your selected chain pulled live from the gas ticker, so the expected math reflects current conditions.

When to use this vs Settings defaults

• Settings → Tasks defaults: standing values applied to every new task.
• Build Task → Gas: per-task override.
• Calculator: dry-run the cost before you commit. Useful when you want to know “if I bump priority to 5 gwei across 50 wallets, what’s the worst case?”

Multiply the worst-case from the calculator by wallet count to get a quick batch budget.
