Airdrop Contract Troubleshooting
Airdropping NFTs to your community is a popular way to provide utility in many NFT-based projects. Using the airdrop contracts, you can airdrop any ERC20, ERC721, or ERC1155 tokens.
To get started, here is a quick overview of how to airdrop NFTs:
- Deploy your NFT/token contract and mint tokens
- Deploy the airdrop contract
- Approve the airdrop contract in your NFT contract via
approveorsetApprovalForAll. We recommendsetApprovalForAllfor large airdrops so you don’t need to approve each token ID individually. - Enter your NFT/token parameters into the airdrop contract’s
airdropfunction and execute
If you encounter an error after following these steps, verify the following:
- You have enough funds in your wallet to cover gas fees
- The airdrop contract has been granted approval on the NFT contract. See the example below:
- Your airdrop parameters use the correct formatting:
- recipients must be an array of quoted addresses:
["0x...","0x...","0x..."] - token ID must be an array of numeric IDs:
[0,1,2]
- recipients must be an array of quoted addresses:
- NFTs aren’t minted/claimed
- Trying to airdrop too many NFTs at once
- Airdropping NFTs to invalid wallet addresses
NFTs aren’t minted/claimed
Make sure you’ve minted the NFTs to your wallet first. You can only airdrop tokens you already own.
Trying to airdrop too many NFTs at once
Most chains limit a single transaction to around 100 recipients. Split large lists into batches of 100 addresses or fewer.
Airdropping NFTs to invalid wallet addresses
If you see execution reverted: ERC1155: transfer to non ERC1155Receiver implementer, one or more addresses in your list aren’t valid ERC1155 recipients. Remove any invalid addresses and try again.
