Features overview

Minting API

Create, edit, and airdrop NFTs on-demand via API calls, abstracting the complexity of contracts, gas fees, and wallets from you and your community


Creating NFTs	With a simple REST request you can: - Deploy a smart contract - Validate, upload, and pin your NFT metadata and media assets to decentralized permanent storage - Mints the NFT - Deliver the NFT to a wallet or email address. If the recipient doesn't have a wallet, one will be created for them instantly, for free
Editing and burning NFTs	In private beta. Contact us
Gas fees	Simply top up credits on the developer console using a debit or credit card. All gas fees are paid by Crossmint, included in the pricing, and abstracted away from you.
Blockchains	- Polygon: live in mainnet and testnet (Mumbai) - Solana: live in mainnet and devnet - Ethereum: coming soon (contact us)

Smart contracts	- Polygon: ERC-721. Contact us for ERC-1155 support - Solana: Read more Bring your own contract: In private beta, contact us
Smart contract ownership	By default, the smart contract will be owned by Crossmint. However, it can be transferred upon request. However, transfer of the ownership may disable certain features like editing or burning NFTs. Contact us if you need to bring your own smart contract. Currently in private beta. Coming self-serve in Q1.
Airdrops recipients	Wallets and emails addresses. If the recipient doesn't have a wallet, one will be created for them instantly, for free
Royalties	In private beta. Contact us
Mint check status	Every mint request returns an id field that uniquely represents each NFT. You can track the status of the mint event using this ID, since minting an NFT can take a few seconds before its finalized on the blockchain. Once it's finalized, this endpoint will provide all onChain data you'll need about the NFT.
Rate-limiting	200 TPS. For special drops, we can allocate additional resources. The baseline TPS will increase in late January/early February. Transactions are queued and submitted to the blockchain at the maximum rate the chain can handle.
Setting up OpenSea or Rarible pages	Contact us to give you edit access to your OpenSea page Concierge service available for enterprise clients
Emails	You are responsible for notifying NFT recipients of the airdrop
