The Signature Drop contract uses the ERC-721A standard to release a collection of unique one-of-one NFTs with lower gas fees for your community compared to the regular ERC-721 standard used in the NFT Drop.
You lazy-mint your NFTs by uploading the metadata and configuring a single claim phase, laying out the rules for how your users can claim NFTs from your drop; such as an allowlist, release date, or delayed reveal.
The "signature" in the name refers to the signature-based minting feature, that allows you to grant users the ability to mint NFT(s) based on a custom set of criteria, checked on-demand. This feature is optional and separate from the claim phase conditions.
Use Cases & Examples
You could use the Signature Drop contract to:
- Release a gas-optimized PFP Collection where each NFT has a different combination of traits
- Allow users that meet certain criteria to be able to claim NFTs from your drop

Lazy Minting NFTs
Lazy minting is the process of uploading your metadata for your NFT(s) without minting them yet.
This is useful for when you want other wallets to mint NFTs from your drop into their own wallets.
To lazy mint NFT(s), click Create to lazy-mint a single NFT, or Batch Upload to lazy-mint multiple NFTs at once.
Delayed reveals allow you to reveal the contents of the NFT to the user later at a specific date and show a placeholder asset in the meantime.
- Reveal upon mint: Collectors will immediately see the final NFT when they complete the minting.
- Delayed Reveal: Collectors will mint your placeholder image, then you reveal it at a later time.
You have the option to add a delayed reveal to a batch of NFTs after you batch upload them.
Setting the Claim Phase
A claim phase is a set of conditions that define when and how your users can claim an NFT from your drop.
The signature drop contract only supports one claim phase, (this claim phase can be edited later).
Within a claim phase, you can define:
- When the claim phase will start
- How many NFTs do you want to drop
- How much do you want to charge per NFT
- What currency do you want to use
- Which wallet addresses are allowed to mint (allowlist)
- How many NFTs can be claimed per transaction
- How many seconds do wallets have to wait between claims
To configure the claim phase, click the Claim Phases tab and Add Claim Phase.
