# Launching a collection

Launching through the Unvault launchpad is by application at onboarding.unvault.com, subject to Unvault's review and sole discretion. Accepted collections launch with a deployed ERC-721AC contract and a drop page that defines phases. A 10% launchpad fee is taken from mint proceeds (see the [Fee Schedule](https://support.unvault.com/policies/fee-schedule)).

## Phases

| Phase | Eligibility | Mechanism |
| --- | --- | --- |
| Allowlist | Addresses supplied by the creator | Signed voucher (EIP-712) issued by Unvault's mint signer; the contract verifies it |
| Bugz | Holders of BUGZ collection tokens at the specified chain and time | Voucher issued after a holder check |
| Public | Anyone | No voucher; per-wallet limits enforced on-chain |

Vouchers are bound to the collection, chain, wallet, phase and quantity, carry an expiry and a nonce, and cannot be reused. Mint caps and pause are enforced on-chain.

## Multi-chain launches

A collection can launch on several chains at once. Total supply is split across chains by configuration, and every minted item is vaultable from its home chain.

## Creator obligations

Creators warrant that they own or license the content, that statements about the project are accurate, and that the collection is not marketed as an investment. See Sections 9 and 17 of the [Terms of Service](https://support.unvault.com/policies/terms-of-service).
