Estimating Cost

Before you launch anything, Skrybit answers the question every marketer asks first: “what would it cost to inscribe this whole campaign?”

Fee tiers: slow / normal / fast

Bitcoin transaction fees float with demand. Skrybit’s fee oracle tracks the live mempool and quotes three tiers:

The campaign cost estimate prices your entire campaign at each tier:

inscriptions = audience addresses × collection items (per distribution mode)
tier total   = inscriptions × (fee rate × inscription size + postage)

• Inscription size comes from your actual media — bigger payloads cost more per inscription.
• Postage is the small amount of sats that rides with each inscription into the recipient’s wallet (an inscription lives on real sats).
• The estimate may also include a cheapest-window hint from Skrybit’s fee forecaster — e.g. “inscribing in ~N hours could save X%” — useful when the drop is not time-critical.

The estimate excludes the platform service fee. The authoritative, all-in price (network cost + service fee) is fixed when the batch is created at launch — that is the exact amount you fund, and it will not change after you see it.

Dry-run the delivery plan

Separately from pricing, you can simulate a launch (dry-run). This runs the full planning path — audience resolution, distribution mapping, batch composition — and returns the plan without creating a batch or touching the chain:

• exactly which addresses receive exactly which items,
• the total inscription count,
• anything that would be skipped and why.

Make the dry-run your pre-flight check: if the plan looks wrong (audience too big, wrong collection linked, unexpected distribution), fix it now — after funding, the batch is in motion.
