The tier is set by the size of the list you publish. If the locked list turns out larger than the tier you paid for, the entries won't freeze until you move up — you are never billed a surprise amount.

Included in every tier

How publishing works

Reviewed first, paid second.

01

Create it

Name the giveaway and pick the Bitcoin block that will draw it.

02

We review it

A quick human check keeps spam off the platform. You'll hear back with an approval — sometimes with an offer attached.

03

Add your entries

Upload the list once approved. The size of that list sets your tier.

04

Pay & publish

Settle the fee, apply any coupon, and the public page goes live.

When am I charged?

Only when you publish. Creating a giveaway, having it reviewed and uploading entries are all free — you can walk away at any point before publishing without paying.

What if my list is bigger than I paid for?

The freeze refuses to lock a list larger than the tier you paid for, and tells you so. Move up a tier and it proceeds. Nothing is drawn or charged behind your back.

Do you have coupons?

Yes. If you have a code, enter it at the payment step and the discount is applied before you pay. Reviewers can also attach an offer to a specific giveaway when they approve it.

Is verification free?

Always. Participants and auditors never pay, never sign in, and can re-run the whole draw in their browser or from the CLI.

Ready when you are.
