Whitelists
Last updated
A whitelist (allowlist) lets a specific set of wallets mint before — or on better terms than — the public. Studio 2.0 supports multi-phase whitelists, so you can run, say, a free early-supporter phase, then a discounted community phase, then the public mint, each with its own price, timing, and wallet list.

Each phase has:
Its own list of wallets — these mint during that phase.
Its own price and window — often a discount, opening before the public mint.
Per-wallet limits — how many each address can mint.
Phases run back-to-back: when one ends, the next begins, and the public mint opens after the last phase closes.
You can build a phase's list from:
A CSV or pasted list of addresses. Both cosmos1… and stars1… addresses are accepted (Studio converts them automatically).
A holder snapshot — allowlist the holders of another collection. Build the list with Snapshots, then drop it in.
Studio de-duplicates every list automatically, so overlapping sources never create problems.
Studio 2.0 keeps a local copy of each phase's member list so you can preview it (with a full-list view) and download it as a CSV at any time — one list per phase.
The whitelist contract itself only stores a cryptographic fingerprint of your list (a "merkle root"), not the addresses. Studio keeps the readable copy for you on the device you built it on. If you need it elsewhere, download the CSV.

You can add a whitelist while creating a collection, or build one on its own and attach it later:
Open Whitelists → Create.
Add your phases, prices, windows, and wallet lists.
Pick the network (testnet or mainnet) and the mint token (ATOM or STARS).
Deploy the whitelist, then use Set on collection to attach it to any collection you manage.
Studio runs a pre-flight check (matching mint token, mint not yet started) before it sets the whitelist, so you can't accidentally attach an incompatible one.
