Send NFTs

Send batch NFTs to emails and wallets, at scale, with a single API call. Recipients don't need a wallet or crypto to receive the NFT.

Use Cases

• Deliver a paid NFT after a buyer pays with mobile in-app purchases (for iOS and Android apps).
• Send an NFT to a customer as a Digital Twin after purchasing a physical item.
• Send an NFT to an attendee of an event as Proof of Attendance.
• Send an NFT to followers of your social media accounts as a Loyalty Program.
• Send a unique claim link to web2 users. They can create an email-based wallet for free or connect a self-custodial wallet later.

Requirements

• An active Minting Toolkit service (see Developer Dashboard: Services.
• Bring your own contract, or let Paper create one for you.

FAQ

How scalable is the API?

The Airdrop API was created with scalability in mind. As soon as a call is made, the request is sent to a task queue that processes the time-consuming parts of the airdrop execution in an async worker. The API itself returns a response as soon as the request is sent to the queue. Our workers gracefully handle the messiness around on-chain and off-chain failures and retries.

The default rate limit is 100 airdrops per minute, and we have load tested 2000-3000 airdrops per minute. We also have a batch API endpoint available for Enterprise customers that processes up to 200 airdrops per API call.

If you have a use case that may require an increased rate limit, please Contact Sales.

How long does a unique claim link last?

The unique claim link sent to a user's inbox lasts 30 days.

How can I make sure only Paper can airdrop from my contract?

Restrict contract calls to Paper to ensure only Paper can airdrop from your contract.

This step is done for you when using a Paper-managed contract.
