Code Snippets

Different ways to token gate

SDK Coming Soon

With the release of our SDK, you'll be able to easily integrate all features within your framework of choice.

Demo API key

You can test the token gating API endpoint using "demo" as the API key. This will work for test networks and is rate limited. This cannot yet be used for airdrop and wallets APIs.

NFT Ownership

User owns 2 ERC721 NFTs

This example verifies that an address holds exactly 2 NFTs from the Bored Ape Yacht Club collection.

User owns at least 1 ERC1155 with a specific token ID

This example verifies that an address holds at least one NFT from the Crypto Baristas collection.

Since the smart contracts that OpenSea and Rarible provide have thousands of different NFT projects listed on them, the only way to accurately token gate something is by including the different IDs that a user should own.
