Stacks revolutionizes the sales process within The Lab, enabling creators to build and publish their mint pages independently. It supports releasing editions using ERC1155 or creating unique 1/1/X collections through ERC721 contracts. This innovative product offers creators an unprecedented way to showcase and sell their work without the hassle of indexing their contracts on external marketplaces, facilitating a direct sales pathway with a 0% creator fee structure.

The thumbnail has no specific dimensions, but it should be square. The maximum file size is 300MB, but we recommend a significantly smaller file instead, as this will ensure that the Stacks page loads quickly.

To set up the Stacks page, you must do an approval transaction and then a transaction to set up the actual Stacks sales contract. In total, this costs about 0.02 eth at 50 gwei.

No. The contract is built so that you sell one 1/1/x series per ERC-721 contract at one time. You can have multiple drops going across different contracts; however, only one can go at a time on a single contract.

Example: Bob has set up a Stack drop for a 1/1/100 collection. He is not able to setup another 1/1/x collection on the same contract until the sale has ended on the first drop. Once the sale has ended (either sold out, time ended, or manually closed), he can create a new drop.

A token on an ERC-1155 contract can only have one live drop for it at the moment. However, if an ERC-1155 contract has multiple tokens created, all of them can have a live stacks drop at the same time.

Example: Bob has an ERC-1155 contract with 3 tokens on it. He can create a Stacks drop for tokens 1, 2, and 3 and have them live simultaneously. However, if he wants to make another drop for token 1, he would have to wait until the first drop has ended for token 1 (either sold out, time ended, or manually closed).

For 721s: No! Stacks utilize lazy minting, meaning the collectors mint the tokens rather than the creator minting and then listing. The only reason to mint 721s is if you want to reserve some pieces for yourself. Minted tokens cannot be added to Stacks drops.

For ERC721: the tokens are minted in the order selected by the creator during Stacks creation. This order is denoted by a numbering schema in the token selection part of the Stacks configuration process.

Currently, the order in which the tokens are minted cannot be randomized, although this is a future-facing feature we plan to integrate. For now, a creator could use a random sequencer (https://www.random.org/sequences/).

For public sale: 12 hours, 24 hours, 48 hours, 1 week, and no limit.

For pre-sale: 1 hour, 2 hours, 12 hours, 24 hours, and 48 hours.

The minimum increment for both is 1 minute, and the maximum is 10 minutes

The draft tokens that were originally Stacked will be removed from your contract page if you decide to "UnStack"/ End your Drop. However, if you contact us with a link to the Stacks page, we'd happily bring those draft tokens back into your contract dashboard so you can restack them or mint them yourself.

Once you publish your Stacks mint page, it will be discoverable within LaunchPad and be displayed as an upcoming drop.

Yes! You can edit the description of the Stacks page, the thumbnail image, informational sections, FAQs, and links by going to your contract page and clicking a published Stacks drop.

No, you cannot pause a Stacks drop. Once a drop date and time are set, they are fixed and cannot be changed. Once the mint phases conclude, the Stacks page cannot be reopened; if you want to run a new mint or extend the mint, you’d have to create a new Stacks drop.

You can edit the start day and time if the Stacks page is still being drafted. Once it is published, you cannot change the drop dates or times.

Yes! When setting up a Stacks page, you’ll use our allowlist template. In this template, you can add a wallet address and specify the number of tokens (max allowance) each wallet address can mint during the pre-sale. It is important to note that if you set a pre-sale allowance of 2 for a collector, and then the public sale allowance is 5, that collector can only mint 3 pieces during the public sale.

Yes! You can set different wallet limits between the pre-sale/allowlist phase and the public sale. It is important to note that if you set a collector's pre-sale allowance to 2 and the public sale allowance is 5 if they minted 2 during the pre-sale, that collector can only mint 3 more pieces during the public sale.

If you’d like to reserve a supply, mint the specific tokens you want to reserve directly to your wallet using the ‘token recipient’ field on the token page. Please note that minted tokens cannot be added to Stacks drops.

Download our allowlist template when setting up your Stacks page. Then, you can add all the wallet addresses and specify the maximum number of tokens minted for each wallet address.

The allowlist should be consolidated into one file and uploaded using our CSV template.

No, it is locked once the allowlist is submitted and the Stacks page is published. So, we encourage you only to upload the allowlist when it is finalized and to double-check all the information before uploading the file.

No. You cannot change the mint allowances once you publish your Stacks drop.

Currently, you can index your 721 collections on Superare and Foundation. You can also import your 721 contracts to Makersplace directly on their platform. All collections are automatically indexed to Opensea as well.

Transient Labs does not have a snapshot tool.

No, unminted tokens do not exist on-chain and cannot be indexed to other marketplaces. Once the tokens are minted via Stacks, you can index the contract to the appropriate marketplace.

The payout address is the wallet address that will receive the mint revenue from your Stacks drop.

Correct. Stacks uses lazy minting, meaning only draft tokens can be added to Stacks drops.
