Who owns my smart contract?

All ERC-721A contracts deployed via Metacommerce are owned by the creator and their wallet.

Our Studio plan currently supports Ethereum.

Our Studio Pro plan supports Ethereum, Polygon, and Solana.

Who pays the gas fees?

Can I launch generative collections (PFP/10k, etc)?

Yes. We support the full process of launching a large generative collection.

Our platform includes a generative design engine, and custom workflows tailored specifically to allow you set-up, and drop large NFT collections.

Does Metacommerce take custody of NFTs sold?

No. Metacommerce is a dApp, when creators deploy contracts and mint NFTs via our creative suite they have full ownership of their work.

What should I name my contract?

Whatever you want! We suggest naming your contract something that aligns with you as a creator, your collection or brand.

What is the difference between ERC-721 and ERC-721a?

ERC-721a is an optimized variant of ERC-721. Its origins can be found with @NFTChance and Nuclear Nerds of the Accidental Apocalypse, and was further popularized and advanced by Azuki Zen. It provides optimized gas fees during minting transactions.

What is the difference between testnet and mainnet?

Think of testnet as the sandbox environment and mainnet as your production environment. It's where you should deploy and QA your contracts prior to pushing live and deploying to mainnet. Once your contract is live on the mainnet, you will have minimal editing abilities.

Are Metacommerce contracts interoperable?

Yes. Your Metacommerce contract is owned by you and can be imported to most major NFT marketplaces. To view compatibility view the list below.

Can I mint tokens for airdrops/giveaways?

Metacommerce enables you to handle airdrops and giveways for ERC-721a contracts. To run an airdrop or giveaway your contract must be live.

Once live you can navigate to your smart contract under the "live contracts" tab to add wallet addresses you'd like to drop NFTs to, or mint to your own wallet.

What are storefronts and minting embeds?

Storefronts and minting embeds are the sales channels currently available via our free platform.

Storefronts allow you to set-up a hosted landing page where users can mint your NFT drop. To set up a hosted page you must connect a custom domain and select a hosting plan.

Minting embeds allow you to embed minting functionality tied to your contract in an existing site (i.e. Shopify, Webflow, Wix, Squarespace) via a simple iframe.

What sales types are currently supported?

We offer two solutions currently for our Studio plan;

Drops (Ideal for PFP/ Large Collections):
Drop a collection on a set date, at a set time. Manage your whitelist and public sales, and access solutions to manage giveaways, treasury mints, and more.

Standard Sales (Ideal for 1 of 1's):
Mint your work ahead of time and sell it your way, this can be done in batches of 1 of 1's or piece by piece, the choice is yours.
